Litecoin Cash

Litecoin Cash (LCC) is a fork of Litecoin itself utilizing an SHA-256 hashing algorithm. While the initial goal was to focus on bringing back SHA-256, along the way we created "Hive Mining," an agent-based system allowing everyday users to participate in securing and hashing the network to earn real LCC rewards.

I downloaded the latest of [Samourai Wallet]1 (not from Play Store, but from an online APK I found, as I do not have Play Store installed on my phone).

You should never download Samourai Wallet from non-official/shady webpages. They provide the SHA-256 key of the official APK so you can compare that with the APK which you have downloaded before installing it. ([[link]14 )

Two or three days ago, [they removed some privacy features from the wallet]3 because of stupid and irritating Google policies that everyone here hates. They said they were moving to F-Droid soon with the full-featured app. That was nice, but am I wrong or they could have done this before they were forced to trim the app? Devs already know Google was applying these pathetic policies, they just tried to apply for an exception — as stated on their blog post.

AFAIK Samourai Wallet added to Play Store ~2016. Google didn't had that policy back then it came out recently ([[link]15 ) If you know how F-Droid works its really slow to update apps since they build it their own and there are lots of apps to be build in general I am also a huge F-Droid fan don't forget to donate/contribute to F-Droid they are doing an awesome work. Samourai Wallet is still in Alpha and it needs to be updated regularly and be shared fast so Google Play is a decent way to do it also it helps to see statics (default by Google if you have Google Services installed on your phone Samourai don't include any trackers, their Exodus Privacy Report here: [[link]16 ) and improve the app fixing bugs etc. are easier since the feedback mechanism which Google Play has. Also a little but non-important thing is Samourai back-end is currently not open-sourced they are working on that if they would add it to F-Droid now they would probably marked as promoting non-free network not so important but a little note. (I don't mean here that their back-end open sourcing is not important the notice mark on F-Droid is not important. Please don't try to draw the subject here.) They will be added to F-Droid really soon once they hit stable and completely open sourced their back-end.

Another thing I found is people (users) openly contradicting the privacy statements made by Samourai — [this particular one]6 being the most “extreme”, as it comes from what it seems to be an eminence here. I know Bitcoin is not oriented towards privacy and that privacy is very difficult to implement, but this made me think: why, for example, cannot I connect to a trusted node without having to run a full node myself, specially configure it and use a VPN to connect to it? Why there seems to be an interest in promoting transaction casting through Samourai servers? Also, what are Ricochet, STONEWALL and PayNym? I suppose they are their implementation of different Bitcoin Improvement Proposals, but can they be trusted? Some users in this sub say there’s something shady with this app.

They stated that clearly and that's why they are still on Alpha. They have explained to these numerous times ([[link]17 ) Also that's really hard to be a light wallet as you stated that the safest way is running your own node to maximize your privacy. As I told this is why they are still in Alpha once they release their back-end you can run their implementation on your full node and fully bypass their infrastructure. They are also working on a plug&play node ([[link]18 ) For their Ricochet, Stonewall and Paynym features you can have a look at their webpages. ([[link]19 , [[link]20 , [[link]21 ) They are all open-sourced features and processed on the client, not on their servers.

Then, there is [this serious claim]12 from a user saying that Samourai Wallet lost some of his bitcoins. I won’t get into details, but it was kind of scary to me since other users told him they were in the same situation.

Welcome to the Bitcoin world while financial sovereignty is something awesome it comes with huge responsibility don't going to list here examples which people lost a ton of bitcoins from paper wallets, other wallets, mistakes etc. I remember that guy as you can see in the comments Samourai team tried to help him also I and my friends tried to help him lots of hours (the chat history is available on Telegram group if someone wants to see it feel free to join and read it its pretty long btw) I invited him to the group ([[link]22 ) and he was a pretty good guy he didn't accused Samourai but just wanted help. The Github repository is there you can search the code/commit history and see that there is nothing wrong in private key generation the problem isn't on the Samourai side.

A few Paper Wallet questions, SHA-256. /r/Bitcoin

A few Paper Wallet questions, SHA-256. /Bitcoin submitted by BitcoinAllBot to BitcoinAll [link] [comments]

[Request] If all the power spent in bitcoin mining were targeted to SHA-256 breaking instead, how many wallets would it have broken?

EDIT: Just to be clear, I guess the answer is zero since the question is wrong, but I'm thinking more in the lines of "if we converted all the FLOPs ever spent in mining into a proper algorithm for breaking wallets, how many, if any, would we have broken"?

The Wallet Import Format on the Bitcoin wiki has different hash results for their SHA-256 hashes than I'm getting…

On the Wallet Import Format page on the Bitcoin wiki (https://en.bitcoin.it/wiki/Wallet_import_format) it has a hexadecimal string
800C28FCA386C7A227600B2FE50B7CAE11EC86D3BF1FBE471BE89827E19D72AA1D 
And it says that the SHA-256 hash of this is
8147786C4D15106333BF278D71DADAF1079EF2D2440A4DDE37D747DED5403592 
I'm not getting that. I've tried both an online hasher, and Python's hashlib, and I'm not getting that hash. Perhaps is the wiki incorrect? Or perhaps are they using a different hash algorithm than SHA-256?
EDIT:
For clarification, I keep getting
e2e4146a36e9c455cf95a4f259f162c353cd419cc3fd0e69ae36d7d1b6cd2c09 
as the SHA-256 hash.

Overwhelmed!

I am not really savvy in coding. So, the sequences of letters and numbers involved are driving me a bit crazy.
Here is what I have done:
Downloaded AwesomeMiner and as a wallet, I used Electrum. Surprisingly, when I check the bitcoin reddit, these two apps are not mentioned. Am I in the wrong track?
Now, in AM app, I used SHA-256 algorithm, BFGMiner(5.4.2), as as a pool, I used bsod mining pool.
BUT, this is what I got:

Even I understand that the mining is not working at all.
Just wondering what should I do now?

However, I check out some video on the bitcoin reddit, so I will start from there.

RESEARCH REPORT ABOUT ARYACOIN

RESEARCH REPORT ABOUT ARYACOIN
Author: Gamals Ahmed, CoinEx Business Ambassador

https://preview.redd.it/a7jv4azk86u51.jpg?width=1600&format=pjpg&auto=webp&s=e4a4dbb5afacd5747076beaa59e6343b805c3392

ABSTRACT

Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain.
The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.

1.INTRODUCTION

The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions.
When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved.
This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency.
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.

1.1 OVERVIEW ABOUT ARYACOIN

Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details.
Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda.
Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified.
Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin.
Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim.
Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details.
Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time.
According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public.
In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks.
AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by
first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.

1.1.1 ARYACOIN HISTORY

Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team.
Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin.
We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said.
Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC.
Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees.
We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.
One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”.
So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.
We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.

1.1.2 ARYACOIN’S MAIN GOAL

Aryacoin’s main goal is to educate people and give them the freedom to use cryptocurrency in any way they want. Aryacoin empowers the users to transfer, pay, trade cryptocurrency from any country around the globe.
Platforms that have been created by Aryacoin Team, as well as those that will go live in future, operate on the same principle and exclude absolutely no one.

1.1.3 PROBLEM ARYACOIN SEEKS TO SOLVE

Aryacoin aims to provide a long-term solution to the problem of double spending, which is still common in the crypto market. The developers of the system have created a peer-to-peer distributed timestamp server that generates computational proof of the transactions as they occur.
Besides, the system remains secure provided honest nodes control more CPU power than any cooperating group of attacker nodes. While Bitcoin was designed not to be regulated or controlled, many exchanges and governments have put regulatory measures on the pioneer cryptocurrency at every step. Aryacoin aims to overcome these restrictions as a free digital currency.

1.1.4 BENEFITS OF USING ARYACOIN

Aryacoin solution offers the following benefits:
  • Real-time update: whether you’re going on a holiday or a business trip, no problem. You can access your coins all over the world.
  • Instant operations: Aryacoin makes it quite easy for you to use your digital wallet and perform various operations with it.
  • Safe and secure: all your data is stored encrypted and can only be decrypted with your private key, seed, or password.
  • Strong security: The system has no control over your wallet. You are 100% in charge of your wallet and funds.

1.1.5 ARYACOIN FEATURES

1. Anonymity
The coin provides decent level of anonymity for all its users. The users can send their transactions to any of the public nodes to be broadcasted , the transaction sent to the nodes should be signed by the private key of the sender address . This allows the users to use the coin anywhere any time , sending transactions directly to the node allows users from any place and country .
2. Real Life Usage
aryacoin’s team is continuously developing new and innovative ways to use the coins , they are currently developing exchanges where the users can exchange the coins without any fees and any restrictions . They also are currently developing other innovative technologies, which would allow users to spend our coins everywhere and anywhere.
3. Offline Exchanges
They are also working with different offline vendors which would enable them to buy and sell the coins directly to our users on a fixed/variable price this would allow easy buy/sell directly using cash . This would allow the coins to be accessible to users without any restrictions which most of the online exchanges have, also increase the value and number of users along with new ways to spend the coin. This would increase anonymity level of the
coin. In addition, introduce new users into the cryptomarket and technology. Creating a revolution, which educates people about crypto and introduce them to the crypto world, which introduces a completely new group of people into crypto and a move towards a Decentralized future!
4. Transactions
When it comes to transactions, Aryacoin embraces a chain of digital signatures, where each owner simply transfers the coin to the next person by digitally signing a hash of the previous transaction and the public key of the next owner. The recipient can then verify the signatures to confirm the chain of ownership. Importantly, Aryacoin comes with a trusted central authority that checks every transaction for double spending.
5. Business Partner with Simplex
Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries.
In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020.
Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.

1.1.6 WHY CHOOSE ARYACOIN?

If you want to use a cryptocurrency that allows you to keep your privacy online even when buying and selling the coins, the Aryacoin team claims that AYA is the way to go. Aryacoin is putting in the work: with more ways to buy and sell, and fixing the issues that were present in the original Bitcoin, plus pushing the boundaries with innovative solutions in cryptocurrencies. You can get started using Aryacoin (AYA) payments simply by having a CoinPayments account!

1.1.7 ARYANA CENTRALIZED EXCHANGE

Aryana, the first Iranian exchange is a unique platform with the following features:
  • The first real international Persian exchange that obtains international licenses and is listed in CoinMarketCap.
  • The first Iranian exchange that has been cooperating with a legal and European exchange for 3 years.
  • The possibility of trading in Tomans (available currency in Iran) at the user’s desired price and getting rid of the transaction prices imposed by domestic sites inside Iran.
  • There is an internal fee payment plan by Iranian domestic banks for depositing and withdrawing Tomans for Aryacoin holders in Aryana Exchange.
  • The number that you see on the monitor and in your account will be equal to the number that is transferred to your bank account without a difference of one Rial.
  • The last but not least, noting the fact that there is a trading in Tomans possibility in Aryana exchange.
Aryana Exchange is using the most powerful, fastest, and most expensive server in the world, Google Cloud Platform (GCP), which is currently the highest quality server for an Iranian site, so that professional traders do not lag behind the market even for a second.
The feature of Smart Trading Robots is one of the most powerful features for digital currency traders. Digital cryptocurrency traders are well aware of how much they will benefit from smart trading robots. In the Aryana exchange, it is possible to connect exchange user accounts to intelligent trading bots and trade even when they are offline.
The injection of $ 1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course.

1.1.8 HOW DOES ARYACOIN WORK?

Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership.

2. ARYACOIN TECHNOLOGY

2.1 PROOF-OF-WORK

They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.
For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.
The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past
block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes.

2.2 NETWORK

The steps to run the network are as follows:
  • New transactions are broadcast to all nodes.
  • Each node collects new transactions into a block.
  • Each node works on finding a difficult proof-of-work for its block.
  • When a node finds a proof-of-work, it broadcasts the block to all nodes.
  • Nodes accept the block only if all transactions in it are valid and not already spent.
This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees.

2.3 AYAPAY PAYMENT SERVICES GATEWAY:

According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world.
This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee.
In other similar systems or even systems such as PayPal, money is stored in the user account.

2.4 CONSENSUS ALGORITHM IN ARYACOIN

The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain.

2.5 DOUBLE-SPEND PROBLEM AND SOLUTION

One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore
be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput.

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

What is your personal financial strategy and vision of Gridcoin?

I started the 2020 year by totally ignoring what is a blockchain, or a cryptocoin. And once I started Qwant-ing (alt Google) it, it was a matter of a few days that I learned how to CPU and GPU mine. I even got a SHA-256 ASIC warming up my flat. Of course, the more I learned about Bitcoin and other PoW coins, the worse I was feeling about the incredible waste of energy with such useless hashes and the consequences of the greedy speculation against the "smaller" coins. So I got rid of the ASIC and while looking at the web for alternative coins using PoS or similar, I found this project, in which I really get identified. Now I'm a happy math and astronomy cruncher. It's just amazing, to be crunching and at the same time, getting rewarded.
There are plenty of things to contribute to this project, and I feel really motivated to get further involved into it. Now my question concerns the "money" side, the financial stuff. Of course Gridcoin is not Bitcoin, although it seems that Gridcoin has a long story behind. I see potential, mostly due to the very active community, the increasing interest in Distributed Computing (and thus the eventual popularity of the Proof-of-Research concept) and the "seriousness" of this project. But the perpetual inflation and the apparent lack of significant volume exchanges might underestimate its value, strictly speaking of the markets dynamics.
The growing scarcity and popularity of the mainstream coins might also be pushing this coin out of the radar of most of the people, explaining the actual stagnancy of the GRC market. And so, here is where I ask to you: what is your vision of Gridcoin? Do you (personally) bet everything for this project, in terms of investments (GRC-only wallets) and computational resources? Or do you diversify your portfolios, speculating as well in another cryptos/stocks?
I'd really like to hear from you, to know if you're interested (or not) in the money side of the project, and, for the affirmative case, to know why you're here and why you want to stay here. Thank you for your attention and your feedback!

Will my recovery phrase still work 100 years+ from now?

Assuming the Bitcoin network exists 100 years from now, would my future grand-children be able to recover my Bitcoin if they found my seed phrase that I created in 2018?
Or is it possible that by then the technology will have evolved (such as migrating to a stronger encryption protocol, perhaps) to such an extent that recovery keys from 100 years ago are no longer compatible?

Looking for Technical Information about Mining Pools

I'm doing research on how exactly bitcoins are mined, and I'm looking for detailed information about how mining pools work - i.e. what exactly is the pool server telling each participating miner to do.
It's so far my understanding that, when Bitcoins are mined, the following steps take place:
  1. Transactions from the mempool are selected for a new block; this may or may not be all the transactions in said mempool. A coinable transaction - which consists of the miner's wallet's address and other arbitrary data - that will help create new Bitcoin will also be added to the new block.
  2. All of said transactions are hashed together into a Merkle Root. The hashing algorithm is Double SHA-256.
  3. A block header is formed for the new block. Said block header consists of a Version, the Block Hash of the Previous Block in the Blockchain, said Merkle Root from earlier, a timestamp in UTC, the target, and a nonce - which is 32 bits long and can be any value from 0x00000000 to 0xFFFFFFFF (a total of 4,294,967,296 nonce values in total).
  4. The nonce value is set to 0x00000000, and said block header is double hashed to get the Block Hash of the current block; and if said Block Hash starts with a certain number of zeroes (depending on the difficulty), the miner sends the block to the Bitcoin Network, the block successfully added to the blockchain and the miner is awarded with newly created bitcoin.
  5. But if said Block Hash does not start with the required number of zeroes, said block will not be accepted by the network, and the miner Double Hashes the block again, but with a different nonce value; but if none of the 4,294,967,296 nonce values yields a Block Hash with the required number of zeroes, it will be impossible to add the block to the network - and in that case, the miner will either need to change the timestamp and try all 4,294,967,296 nonce values again, or the miner will need to start all over again and compose a new block with a different set of transactions (either a different coinable transaction, a different set of transactions from the mempool, or both).
Now, what I'm trying to figure out is what exactly each miner is doing differently in a mining pool, and if it is different depending on the pool.
One thing I've read is that a mining pool gives each participating miner a different set of transactions from the mempool.
I've also read that, because the most sophisticated miners can try all 4,294,967,296 nonce values in less than a fraction of a second, and since the timestamp can only be updated every second, the coinbase transaction is used as a "second nonce" (although, it is my understanding that, being part of a transaction, if this "extra nonce" is changed, all the transactions need to be double hashed into a new Merkle Root); and I may have read someplace that miners could also be given the same set of transactions from the mempool, but are each told to use a different set of "extra nonce" values for the coinbase transaction.
Is there anything else that pools tell miners to do differently? Is each pool different in the instructions it gives to the participating miners? Did I get anything wrong?
I want to make sure I have a full technical understanding of what mining pools are doing to mine bitcoin.

Could anyone reverse engineer private keys from public ones? I know it's meant to be impossible, but...

Surely whatever the future brings, it will bring UNTOLD supercomputing power. Computers are already that much better at cryptographic problem-solving, thanks to Bitcoin itself.
SHA256 hash may be high-grade for its time, but am I correct in saying that all you need to beat it is more raw computing power? A large amount, but... no higher degree of complexity. Just power and time.
Some claims have been made that private keys have already been reverse engineered from public ones.
It does seem implausible, but presumably anybody who accomplished this task would end bitcoin and destroy a 100 billion dollar market. Probably a few teams working on it right now.
Presumably Satoshi knows precisely how the hashing function works. Wouldn't that help him to reverse engineer keys? If not, why not?

What is Blockchain Technology?

What is Blockchain Technology?
The original article appeared here: https://www.securities.io/what-is-blockchain-technology/
Its been almost ten years since Satoshi Nakamoto first introduced Blockchain technology to the world in his 2008 Bitcoin Whitepaper. Since that time, these revolutionary networks have gained popularity in both the corporate and governmental sectors. This growth is easily explained when you consider that blockchain technology provides the world with some unique advantages that were previously unimaginable. Consequently, today, you can find blockchain technology in nearly every sector of the global economy.

What is Blockchain Technology?

A blockchain is a network of computers that share a distributed ledger across all network participants (nodes). This strategy is far different than say, fiat currencies that originate from a centralized authority figure. Importantly, this ledger keeps an unbroken chain of transactions since the birth of the network. This “chain” of transactions grows larger as new “blocks” of transactions are approved and added to it.
Bitcoin Whitepaper
In order to approve new transactions, each node works together with others to validate new blocks. Additionally, the nodes also validate the current state of the entire blockchain. In order for a new block of transactions to be added to the blockchain, they must receive approval from 51% of the network’s nodes. Nodes are also referred to as miners. In this manner, blockchain networks are decentralized networks that provide unmatched security to the world of digital assets.

Security via Decentralization

Decentralization is an important aspect of blockchain technology because it makes these revolutionary ledgers immutable and unalterable. In fact, since there is no centralized attack vector, hacking a blockchain is nearly impossible. The larger the blockchain network, the more secure the data on it remains.
For example, let’s look at the world’s largest blockchain, Bitcoin. Currently, the Bitcoin blockchain has over 10,000 active nodes located across the globe. This distribution means that in order for an attacker to alter even just one tiny piece of information on the blockchain, they would need to successfully hack 5,000+ computers at once.
While this task may not be impossible for the quantum computers of the future, it’s so unprofitable that it makes no sense to even attempt such a monumental task. Additionally, on top of successfully hacking 5000+ computers at once, an attacker would also need a supercomputer to recalculate the new blockchain transactions in time to introduce them into the network. It would literally be more affordable to create a new cryptocurrency from scratch.

Consensus Mechanisms

One of the reasons why blockchain networks are so secure is the integration of consensus mechanisms. Consensus mechanisms are cryptographic protocols that leverage the participants of a blockchain network in securing its data. In the case of Bitcoin, the Proof-of-Work (PoW) consensus mechanism is used.

Proof-of-Work (PoW)

The Proof-of-Work consensus mechanism was revolutionary to the world of cryptography when it was first introduced years prior by Adam Back in his Hashcash whitepaper. In the concept, Back describes the integration of a mathematical equation to the network’s security protocols. In this way, every computer can show “proof” of their work securing the network.

Miner Rewards

It’s important to understand that nodes receive a reward for their mining efforts. These rewards adjust automatically depending on the network’s difficulty and value. In the case of Bitcoin, miners originally received 50 Bitcoin for their efforts. Today, this seems like fortune, but back in 2009, Bitcoin was only worth pennies. As the value of the token rises and the network goes, the mining rewards shrink. Today, Bitcoin miners receive 6.5 BTC if they add the next block to the chain.

SHA-256

Notably, every node validates and secures the blockchain, but only one gets to add the next block of transactions to the network. To determine who the next miner is that gets to add this block, every computer competes in a mathematical race to figure out the PoW equation. In the case of Bitcoin, the equation is known as SHA-256. Importantly, the first SHA algorithm dates back to Hashcash. This early version of the equation was known as SHA-1.
Notably, the SHA-256 equation is so difficult that it’s easier and more efficient for your computer to just make random guesses rather than attempting to figure out the equation directly. The answer to the equation must begin with a predetermined amount of 0s. In the Bitcoin blockchain, the equation’s answer must start with four zeros. However, if the network’s congestion rises, so does the difficulty of these equations. This difficulty adjusts by the addition of another zero at the beginning of the required SHA-256 answer.
Similarly to traditional commodities such as gold, there are costs that are associated with the creation and introduction of these digital assets into the market. These random guesses utilize intense computational power. This power equates to real-world costs such as electricity bills. Studies have shown that securing the Bitcoin network can use more electricity than required by entire countries. Luckily, over 80% of Bitcoin’s power consumption comes from renewable sources such as solar or hydroelectric. This cost of mining also adds measurable value to each Bitcoin.

Miners

As Bitcoin began to gain in profitability, its network’s computing power expanded significantly. In the beginning, nodes, also known as miners, could mine for Bitcoin using nothing more than your home PC. Eventually, miners realized that graphic cards were far better at the repetitive guessing required to figure out the SHA-256 algorithm. This led to a computational race in the market.

ASIC

Eventually, large blockchain firms such as Bitmain introduced Application Specific Integrated Circuit (ASIC) miners into the equation. These purpose-built miners were thousands of times more efficient at guessing the SHA-256 algorithm than the GPUs and CPUs before them. Consequently, their introduction created a scenario in which the average miner now needed to invest thousands in mining equipment to stay relevant.

Mining Pools

Luckily, some creative minds in the field began to think of ways to level the playing field out again. They developed “mining pools.” A mining pool is a network of miners that all share computational power for the common goal of mining blockchain transactions. Importantly, mining pool participants receive a percentage of the reward based on their contributions to the network’s overall hash (computational power).
Importantly, over the last three years, there has been a push to move away from power-hungry consensus mechanisms such as PoW. This desire to secure blockchains in a more efficient manner has led to the development of some truly unique consensus mechanisms in the sector.

Proof-of-Stake (PoS)

The Proof-of-Stake mechanism does away with the difficult mathematical algorithms and instead utilizes a more psychological approach to securing the network. In a PoS blockchain, users don’t need to compete mathematically to add the next block to the blockchain. Instead, PoS users “stake” their coins via network wallets to secure the network. The way staking works is simple.
Keeping a certain amount of coins in your wallet allows you to participate in transaction validations. The more coins you stake, the more likely the chances are you get to add the next block of transactions to the network. In most PoS systems, a miner from those with the most tokens staked at the time receives the chance to add the blocks.
The advantages of a PoS consensus mechanism are immediately evident. For one, you don’t need to pour tons of resources into your network to keep it safe. Additionally, since nodes are chosen based on their amount of staked coins, there is never a scenario in which a node gains anything from validating incorrect transactions. Basically, a hacker would have to fully invest in the cryptocurrency prior to attacking the network. In this way, PoS systems create a huge deterrent to attackers.

The Future of Blockchain Technology

Blockchain technology has come a long way from its early days as a means to secure cryptocurrency networks. Today, blockchain technology has numerous uses across every type of industry imaginable. Specifically, blockchain programs have impacted the logistical, financial, and data security sectors in a major way.

Blockchain Technology Logistics

Blockchain logistical systems are more efficient and cost-effective to operate than traditional paper-based models. In fact, the immutable and unalterable nature of blockchain tech makes it ideally suited to logistical tasks. Soon, you may be able to ascertain much more information regarding the creation and delivery of your products thanks to these new-age systems emerging.

Fundraising

Blockchain technology has also altered the way in which businesses raise funds. In a traditional corporate crowdfunding strategy such as an IPO, companies must balance between cost-effectiveness and participation. The inability to process smaller transactions meant that for the longest time, companies had to turn away potential investors. Nowadays, blockchain technology enables businesses to easily automate these procedures via smart contracts.

Smart Contracts

Smart Contracts feature preprogrammed protocols that execute when they receive a certain amount of cryptocurrency sent to their address. These contracts live on the blockchain and enable remarkable functionality. For example, in the case of fundraising, a smart contract can automate processes such as the approval of investors and the distribution of funds.

Blockchain Technology Today

You can expect to see further expansion of the blockchain sector in the coming months as more governments and institutions explore its benefits. For now, the blockchain revolution is well underway.

30+ Reasons Why Cryptocurrencies Are Worthless

1)It is possible to change the code through a miner vote or a fork and change the total supply or anything. DASH did it : they reduced the total supply from 84M to 18.9M a few years ago. They could also increase it to 999 Trillions if they wanted to so that millions of DASH are mined every week.

2)You can also fork bitcoin anytime , start over from 0 and claim it's the real bitcoin. (BCH , BSV , BTG , LTC , BCD etc)

3)Why would you pay $10,000 for a digital collectible unit called BTC when you can use BCH or TRX or LTC .. you name it. They work just as fine and cost less. There is no rarity like in gold.

4)Think of any amount you hold in ethereum as a gift card to use smart contracts on the ETH blockchain. Ridiculous. You’d rather hold a wal mart gift card or even simply cash.

5)Private keys may be bruteforced as we speak. Quintillions entries a second. When they’ll have enough bitcoins under control , they could move them all at once instantly.(At least 45,000 ETH have been stolen this way for now through ethereum bandit)SHA 256 is too old , bitcoin is 10 years old , it is not secure enough , quantum computing could potentially break it.

6)And that’s if people don’t find a way to create an infinite amount of coins to sell on exchanges.. it happened with monero , stellar , bitcoin , zcash , zcoin , eos , etc..

proofs :

“Bitcoin , Coindesk : “The Latest Bitcoin Bug Was So Bad, Developers Kept Its Full Details a Secret”an attacker could have actually used it to create new Bitcoin — above the 21 million hard-cap of coin creation — thereby inflating the supply and devaluing current bitcoins.”

Stellar : “Stellar Inflation: Glitch Leads to 2.25 Billion Extra XLM Printed”

Monero : “A bug in the Monero (XMR) wallet software that could enable fake deposits to exchanges has been recently brought to public attention through a Medium post”

Zcoin : Forged coins were created, but not exceeding 1% of the circulating supply. We will release further details on exact numbers when Sigma is released.

EOS : “Hackers Forge Billion EOS Coins to Steal Real Crypto From DEX “

Zcash : “Zcash Team Reveals It Fixed a Catastrophic Coin Counterfeiting Bug” etc..

7)Segwit , and especially Lightning network is a very complex technology and it will inevitably have flaws , bugs , it will be exploited and people will lose money. That alone can cause bitcoin to drop very low levels.

8)Then miners may be losing millions so they will stop mining , blocks may be so slow , almost no transaction will come though , and bitcoin may not have enough time to reach the next difficulty adjustement. This is reffered to as a death spiral. Then every crypto even those with no mining involved may crash hard.

9)Many crypto wallets are unsafe and have already caused people to lose all their investment , including the infamous “parity wallet”.

10)It is NOT trustless. you have to trust the wallet you’re using is not just generating an address controlled by the developper , you have to trust the node the wallet connects to is an honest node , you have to trust a Rogue state or organization with enough computing power will not 51% attack the network. etc..

11)Bitcoin is NOT deflationary. Bitcoins are created every blocks (roughly every 10 minutes) and you wil be dead by the time we reach the 21 million current hard cap.

12)Bitcoin price may artificially be inflated by Tether.

13)It’s an energy waste , an environmental catastrophy.

14)The only usecases are money laundering , tax evasion , gambling , buying on the dark net , evading sanctions and speculation.

15)Governments will ban it if it gets too big , and they have a big incentive to do so , not only for the obscure usecases but also because it threatens the stability of sovereign currencies. Trump could kill bitcoin with one tweet , force fiat exchanges to cease activity.

16)Most cryptos are scams , the rest are just crazy speculative casino investments.

17)It is pyramidal : early adopters intend to profit massively while last comers get crushed. That's not how money works. The overwhelming majority of crypto holders are buying it because they think they will be able to sell it to a higher price later. Money is supposed to be rather stable. That's why the best cryptocurrencies are USDT USDC etc..

18)The very few stores accepting bitcoin always have the real price in the local currency , not in bitcoin. And prices like 0.00456329 BTC are ridiculous !

19)About famous brokers listing bitcoin : they have to meet the demand in order to make money , it doesn't mean they approve it , some even short it (see interactive broker's CEO opinion on bitcoin)

20)People say cash is backed by nothing and losing value slowly , and yes it is very flawed , but there is a whole nation behind it , it's accepted everywhere , you can buy more things with it.

21)Everybody in crypto thinks that there will be a new bullrun and that then , they will sell. But because everybody thinks it will happen , it might not happen. The truth is past performance doesn’t indicate future performance and it is absolutely not guaranteed that there will ever be another bullrun. The markets are unpredictable.

22)Also BTC went from about $0.003 to the price it is today , so don’t think it’s cheap now.

23)There is no recourse if you’re scammed/hacked/made a mistake in the address etc. No chargebacks. But it might be possible to do a rollback (blockchain reorganization) to reverse some transactions. BSV did it.

24)In case of a financial crisis , the speculative assets would crash the most and bitcoin is far from being a non speculative safe heaven ; and governments might ban it to prevent fiat inflation to worsen.

25) Having to write down the private key somewhere or memorize it is a security flaw ! It’s insane to think a system like this will gain mass adoption.

26) The argument saying governments can not ban it because it is decentralized (like they banned drugs) doesn’t work for cryptos. First , drugs are much harder to find and much more expensive and unsafe because of the ban , and people are willing to take the risk because they like it. But if crypto is banned , value will drop too much , and if you can’t sell it for fiat without risking jail , goodluck to find a buyer. Fiat exchanges could close. Banks could terminate every crypto related bank account. And maybe then the mining death spiral would happen and kill all cryptos.

27) Crypto doesn’t exist. It’s like buying air. It’s just virtual collectibles generated by a code. Faguzzi, fugazzi, it’s a whazzie, it’s a whoozie.. it’s a.. fairy dust. It doesn’t exist. It’s never landed. It’s no matter, it’s not on the elemental chart. It… it’s not fucking real!

28) Most brilliant guys have come out and said Bitcoin was a scam or worthless. Including Bill Gates , Warren Buffet , The Wolf Of Wall Street…

29) Inflation is necessary for POW , BTC code will have to be changed to bypass the 21M cap or mining will die ! If BTC code is not changed to allow for miners to be paid reasonably , they will cease mining when the bitcoin block reward gets too low.Even monero understood it ,the code will have to be changed to allow for an infinite bitcoin supply (devaluating all current bitcoins) or the hash will decrease and the security of bitcoin will decrease dramatically and be 51% attacked

30) Don’t mix up blockchain and cryptos. Even blockchain is overrated. But when you hear this or that company is going blockchain , it doesn’t mean they support cryptocurrencies.

31) Craig Wright had a bitcoin mining company with Dave Kleinman (he died) and on january 1 2020 he claims he will be able to access the 1.1M BTC/BCH/BTG from the mining trust. He may or may not dump them on the market , he also said BTC had a fatal flaw and that by 2019 there will be no more BTC.

32) Hacks in cryptos are very common and usually massive. Billions of dollars in crypto have been stolen in the last 6 years. In may 2019 Binance was hacked and lost 7,000 BTC (and it’s far from being the biggest crypto hack).

33) Bitcoin was first. It's an ancient technology. Newer blockchains have privacy, smart contracts, distributed apps and more.Bitcoin is our future? Was the Model T the future of the automobile? (John Mc Afee)

34) IOTA investiguating stolen funds on mainnet. IOTA shuts down the whole network to deal with trinity wallet attack.

35) Compared to bitcoin other cryptos work just as fine and don't waste so much energy.

36 ) Everytime miners disagree on the updates it will create another version of bitcoin : problem of governance and legitimacy.

37) Cryptos are only legitimate if they act as a credit for a redeemable asset like USDT or gold backed coins.


While the native language of the writter is not english , I think you get the point and it doesn't make it any less relevant.

Mining and Dogecoin - Some FAQs

Hey shibes,
I see a lot of posts about mining lately and questions about the core wallet and how to mine with it, so here are some facts!
Feel free to add information to that thread or correct me if I did any mistake.

You downloaded the core wallet

Great! After a decade it probably synced and now you are wondering how to get coins? Bad news: You don't get coins by running your wallet, even running it as a full node. Check what a full node is here.
Maybe you thought so, because you saw a very old screenshot of a wallet, like this (Version 1.2). This version had a "Dig" tab where you can enter your mining configuration. The current version doesn't have this anymore, probably because it doesn't make sense anymore.

You downloaded a GPU/CPU miner

Nice! You did it, even your antivirus system probably went postal and you started covering all your webcams... But here is the bad news again: Since people are using ASIC miners, you just can't compete with your CPU hardware anymore. Even with your more advanced GPU you will have a hard time. The hashrate is too high for a desktop PC to compete with them. The blocks should be mined every 1 minute (or so) and that's causing the difficulty to go up - and we are out... So definitly check what is your hashrate while you are mining, you would need about 1.5 MH/s to make 1 Doge in 24 hours!

Mining Doge

Let us start with a quote:
"Dogecoin Core 1.8 introduces AuxPoW from block 371,337. AuxPoW is a technology which enables miners to submit work done while mining other coins, as work on the Dogecoin block chain."
- langerhans
What does this mean? You could waste your hashrate only on the Dogecoin chain, probably find never a block, but when, you only receive about 10.000 Dogecoins, currently worth about $25. Or you could apply your hashrate to LTC and Doge (and probably even more) at the same time. Your change of solving the block (finding the nonce) is your hashrate divided by the hashrat in sum - and this is about the same for Doge and LTC. This means you will always want to submit your work to all chains available!

Mining solo versus pool

So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or $2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.

Buying an ASIC

You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per $ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...

Making profit

You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.

Cloud Mining

Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc.
Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you $54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same.
Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.

Alternative coins

Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!

Folding at Home (Doge)

Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much.
Thanks for reading

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

Are we naive to think the elites were surprised by btc/blockchain? Some interesting points inside.

I'll start with saying the concept of blockchain was created by NSA with a bunch of cryptologists in 1994-1997 so they have known about it for a long time(even created it, actual paper below)
disclaimer: theres just a tiny bit of a conspiracy spin to it
With that as a starting point, it’s now becoming increasingly evident that Bitcoin MAY be a creation of the NSA and was rolled out as a “normalization” experiment to get the public familiar with digital currency. Once this is established, the world’s fiat currencies will be obliterated in an engineered debt collapse (), then replaced with a government approved cryptocurrency with tracking of all transactions and digital wallets by the world’s western governments.
.
What evidence supports this notion? First, take a look at this document entitled, “How to make a mint: The cryptography of anonymous electronic cash.” This document, released in 1997 — yes, twenty years ago — detailed the overall structure and function of Bitcoin cryptocurrency.
https://digitalcommons.wcl.american.edu/cgi/viewcontent.cgi?article=1389&context=aulr
.
[1997]With the onset of the Information Age, our nation is becoming increasingly dependent on network communications. Computer-based technology is impacting significantly our ability to access, store, and distribute information.
.
An electronic payment protocol involves a series of transactions, resulting in a payment being made using a token issued by a third party.
.
The most common example is the electronic approval process used to complete a credit card transaction; neither payer nor payee issues the token in an electronic payment.
.
The electronic payment scenario assumes three kinds of players:
" a payer or consumer ("Alice"),
" a payee, such as a merchant ("Bob"), and
" a financial network with whom both Alice and Bob have accounts(the "Bank")
Why would they want blockchain? Its even mentioned in the paper.
The untraceability property of electronic cash creates problems in detecting money laundering and tax evasion because there is no way to link the payer and payee. To counter this problem, it is possible to design a system that has an option to restore traceability using an escrow mechanism.
Theyre talking about blockchain and tracing money in fucken 1997.
So whilst btc is great and open source but do you think this is going to replace banks? That they didnt see this coming? Blockchain is great for goverment.
Btc is Robin Hood style money and its gonna get smashed.
.
"See Tony Eng & Tatsuaki Okamoto, Single-Term Divisib Electronic Coins, 1994 ADvANcES IN CRYPTOLOGY-EUROCRYPT '94, LECTURE NOTES IN COMPUTER SGI. 311, 313."
Three divisible off-line cash schemes have been proposed, but at the cost of longer transaction time and additional storage.
Eng/Okamoto's divisible scheme is based on the "cut and choose"
Okamoto's scheme is much more efficient and is based on Brands' scheme but also will work on Ferguson's scheme.'
Okamoto and Ohta's scheme is the most efficient of the three, but also the most complicated.
It relies on the difficulty of factoring and on the difficulty of computing discrete logarithms.
Eng/Tatsuaki Okamoto and Ohta's scheme
Tatsuaki Okamoto +eng+ohta
Satoshi Nakamoto
Did these 3 create this or?
??
.
It is evident that SHA-256, the algorithm Satoshi used to secure Bitcoin, was not available because it came about in 2001. However, SHA-1 would have been available to them, having been published in 1993.
.
On top of the fact that the NSA authored a technical paper on cryptocurrency long before the arrival of Bitcoin, the agency is also the creator of the SHA-256 hash upon which every Bitcoin transaction in the world depends. “The integrity of Bitcoin depends on a hash function called SHA-256, which was designed by the NSA and published by the National Institute for Standards and Technology (NIST).”
.
“If you assume that the NSA did something to SHA-256, which no outside researcher has detected, what you get is the ability, with credible and detectable action, they would be able to forge transactions. The really scary thing is somebody finds a way to find collisions in SHA-256 really fast without brute-forcing it or using lots of hardware and then they take control of the network.” Cryptography researcher Matthew D. Green of Johns Hopkins University said.
.
Chaum developed ecash way back in 1983, long before the large scale propagation of the world wide web. Chaum was a proponent of anonymity in transactions, with the express demand that banks and governments would have no way of knowing who had purchased what.
.
Although Bitcoin adds mining and a shared, peer-to-peer blockchain transaction authentication system to this structure, it’s clear that the NSA was researching cryptocurrencies long before everyday users had ever heard of the term.
.
‘I wouldn’t be surprised if he is actually an American working for the NSA specializing in cryptography. Then he got sick of the government’s monetary policies and decided to create Bitcoin.’ Vitalik Buterin account then replied: ‘Or the NSA itself decided to create Bitcoin.
Here you see a freedom of information act letter to the NSA asking about their involvement in BTC and they say its classified lol
Why the fuck would that be classified?
We're fucked guys.

Waltonchain adds GNU General Public License details to code - BUT does the code contain this?

Waltonchain adds GNU General Public License details to code - BUT does the code contain this?
Dear Crypto community,
Yesterday we saw Waltonchain release their Open Source code which resulted in huge criticism regarding the oversight of removing the original copyright to the original codebase, Ethereum Go, on which it is based.
Following this, the team have now updated the code to show the original copyright:
Image from Github
Source: https://github.com/WaltonChain/WaltonChain_Gwtc_Src/blob/mastep2p/rlpx.go?utm_source=share&utm_medium=ios_app
Github: https://github.com/WaltonChain?tab=repositories

I'd like to say thank you to the community for having such strong opinion on this matter, and for all the subreddit admins that assisted in creating clarity toward this. As a global community we should hold every blockchain up to the same standards, and I am grateful that this was shown in regard to the GNU General Public License.

Now that the issue is resolved, and since Waltonchain is currently a hot topic, I implore all the coders and devs out there to delve deep into the code to see exactly what Waltonchain have released. Not just the modification to the eth codebase, but the additional code. What does the code allow?

What we've been told as a community is that the Waltonchain source code has changes that allows for:
  • Security - DASH X11 - Most cryptographic algorithms used in cryptocurrencies use only one hash function for calculation. There are 11 of them in X11, which provides a higher degree of protection against hackers and scams. Waltonchain has customised the DASH X11 hashing algorithm to fit their purpose.
  • More secure than Bitcoin. The Bitcoin algorithm is SHA-256 is based on a previous secure hash algorithm family of standards, namely SHA-2, the hash functions within the X11 algorithm all successfully made it into the second-round in search for a new, more secure standard — SHA-3. Keccak, the function which won the competition and is therefore the new standard on which SHA-3 is based on, can at the very least be considered more secure that SHA-256.
  • Efficiency — Waltonchain have produced ASICs with the equivalent hashing power of 200GPUs (32–40kW) whilst using only 135W, thus helping the parent chain become decentralised
  • PoS aspect works in tandem with PoW, in that it adds a reduced difficulty based on number of coins held and time between blocks. Effectively the longer coins are held and the longer the time between blocks, the lower the difficulty for mining blocks. This again enhances the power efficiency of the network in its entirety.
  • Fast cross-chain searching via Proof of Labour —PoL enables hash values or indices from sub-chains (child chains) to be synced with the parent chain in a ‘cross chain index mechanism’ to enable fast searches for data via the parent chain.
  • Scalibility — Unlimited scalibility due to child chains; each CC is an independent blockchain (or DAG) using its own consensus mechanism (PoS, PoA, PoW, PoeT, etc) and can store data within itself. The parent chain by nature therefore cannot become bloated.
  • Atomic Swaps — PoL by nature ensures a record of every inter-chain transaction is held, and allows the function of atomic swaps between currencies.

Also to note is that the code has been audited by Knownsec, the same company that audited projects like HPB and NANO.

Lets have an open dialogue and talk about these features of the code - but firstly, do they exist? Hopefully people will approach this with the same enthusiasm as they did yesterday.

EDIT 1st June: A user on the Waltonchain sub has done an analysis which by the looks of it, disproves the initial assessment by many of the 'blockchain experts' in cc that have said the open source code is simply a copy and paste . https://www.reddit.com/waltonchain/comments/bveqea/changeset_goethereum_v171_to_gwtc_v110/
It is interesting to see just how much people love to hate Waltonchain that they spread misinformation either intentionally, or unintentionally, and that it gets the most attention out of any announcement.
