  • Solana: How to directly verify ed25519 signatures in a contract

    Direct Verification of Ed25519 Signatures in a Solana Contract

    As blockchain developers, we are often challenged to integrate different signing mechanisms into our contracts. One such mechanism is ed25519, which allows for secure and efficient digital signatures using a cryptographic hash function and a private key. While there are solutions that allow for indirect verification of ed25519 signatures, placing the signature statement and the call statement in a single transaction can be cumbersome.

    In this article, we explore an alternative approach to directly verifying ed25519 signatures in a Solana contract.

    The Problem

    Before we get into the solution, let’s look at some common problems:

    • Transaction Size: Direct verification of ed25519 signatures requires a significant amount of storage space. By putting the signature statement and the call statement in a single transaction, we risk exceeding the maximum transaction size limit.
    • Performance overhead: Verifying each individual signature can introduce additional delays that may be unacceptable for high-frequency trading or real-time applications.

    The Solution

    To address these concerns, we implement a custom solution that uses the verify directive to directly verify ed25519 signatures. This approach requires careful consideration of the following aspects:

    Signature verification function

    We create a special function in our contract that verifies ed25519 signatures. This function takes the input of the signature and the hash of the contract repository as arguments.

    pragma solidity ^0.8.0;

    Contract SignatureVerifier {

    // ... (other variables)

    function verifyEd25519Signature(

    bytes32 _signature,

    address _from,

    bytes_storage_Hash,

    uint256 _gasLimit

    ) public view return (bool) {

    // Verify the signature with ed25519

    require ed25519Verify(_signature, _from, _storageHash, _gasLimit);

    return true;

    }

    }

    ed25519 library integration

    We will use the `solana-verify'' library to perform the actual verification. This library provides a high-level interface for verifying signatures with ed25519.

    pragma solidity ^0.8.0;

    library solanaVerify {

    function verify(uint256 _hash) internal view returns (bool);

    }

    Contract SignatureVerifier {

    using solanaVerify.sol(solanaVerify);

    // ... (other variables)

    function verifyEd25519Signature(

    bytes32 _signature,

    address _from,

    bytes_storageHash

    ) public view returns (bool) {

    return verify(_signature, _from, _storageHash);

    }

    }

    Transaction Structure

    To avoid exceeding the maximum transaction size limit, we structure our contract as follows:

    pragma solidity ^0.8.0;

    Contract SignatureVerifier {

    // ... (other variables)

    bytes32 public signature;

    Address to the public from;

    bytes storage storageHash;

    function setSignature(bytes32 _signature) public {

    requirement ed25519Verify(_signature, from, storageHash, 100000); // 100k gas

    signature = _signature;

    from = address(...);

    storageHash = _storageHash;

    }

    function verifyEd25519Signature(

    bytes32 _signature,

    address _from,

    bytes storage _storageHash

    ) public view return (bool) {

    requirement ed25519Verify(_signature, _from, _storageHash, 100000); // 100k gas

    return true;

    }

    }

    Example Usage

    To use this solution, create a new contract and import the SignatureVerifier contract.

  • Ethereum: Why this ugly looking formula to calculate ‘target’ from ‘nBits’ in block header: target = coefficient * 256**(exponent-3)

    The Math Behind Ethereum’s “Target” Calculation

    Ethereum, a decentralized blockchain platform, uses complex mathematical formulas to calculate its block rewards. One such formula that has sparked curiosity among developers and users alike is the calculation for the “target” in the block header. Specifically, we discuss why this particular formula is used and whether it is necessary.

    Why the ugly formula?

    The formula target = coefficient 256*(exponent-3) may look ugly at first glance, but it serves its purpose well in calculating the target amount for each block. Let’s break down the components of this formula:

    • coefficient: This is a constant value that determines the base amount that miners will be rewarded. It is usually set by the Ethereum team and can vary depending on the block number.


    256

    (exponent-3):* This part of the formula represents a significant power of 2 that contributes significantly to the overall reward structure.

    While this formula may not be aesthetically pleasing in terms of design, its purpose is clear: it calculates the base amount rewarded for each block. The exponent (“exponent”) determines how many times the power of 2 is multiplied, resulting in an exponentially larger value.

    Why nottarget = coefficient 256 (exponent)?*

    The alternative formula “target = coefficient 256* (exponent)” may seem more intuitive and understandable. However, there are several reasons why this formula is preferred:

    • Predictability: Using exponent-3 instead of exponent makes the reward calculation more predictable and consistent across different block numbers.
    • Consistency: This approach ensures that miners receive a fixed amount regardless of their location or network conditions. It also reduces the likelihood of abuse, as rewards are standardized.
    • Security: Using a fixed power of 2 (in this case, “256”) provides an additional layer of security by ensuring that the reward calculation is deterministic and resistant to tampering.

    Conclusion

    While the formula “target = coefficient 256* (exponent-3)” may seem unattractive at first glance, it plays a fundamental role in calculating the base amount rewarded for each block. Using this specific formula ensures predictability, consistency, and security, making it a fundamental part of Ethereum’s reward structure. As developers and users continue to explore the complexities of Ethereum, understanding these mathematical formulas will become increasingly important for optimizing performance and ensuring the smooth operation of the network.

  • Sei (SEI), OKX, Validator Nodes

    Crypto

    Cryptocurrency has been a hot topic in recent years, with many new and established players entering the market. One of the most prominent cryptocurrencies is Bitcoin (BTC), which was launched in 2009 by an individual or group using the pseudonym Satoshi Nakamoto. Since its launch, Bitcoin has become one of the most widely recognized and adopted cryptocurrencies, with a market capitalization of over $2 trillion.

    Another major cryptocurrency is Ethereum (ETH), which was launched in 2015 as an open-source decentralized application platform. Ethereum’s native cryptocurrency, Ether (ETH), is used to pay for computational services on the network, known as gas. Ethereum has gained popularity due to its ability to run smart contracts and decentralized applications (dApps) without the need for a central authority.

    SEI

    The Securities Exchange Institute (SEI) is a US-based regulatory body that oversees the cryptocurrency market. In 2020, SEI issued a statement stating that it would not be accepting or registering new cryptocurrencies or digital assets as securities. This move was made in response to growing concerns about the volatility and potential risks associated with cryptocurrencies.

    OKX

    OKEx (formerly known as Option Trading Exchange), is a cryptocurrency derivatives exchange based in Hong Kong. Founded in 2013, OKEx has become one of the largest and most popular exchanges for buying and selling digital assets, including Bitcoin, Ethereum, and other cryptocurrencies. In addition to its core trading platform, OKEx also offers various services such as margin trading, futures contracts, and staking.

    Validator Nodes

    Validator nodes play a crucial role in maintaining the security and integrity of a blockchain network. These nodes are responsible for verifying transactions on the network and adding them to the blockchain. They are essentially nodes that validate the state of the blockchain before allowing it to be considered “officially” part of the network.

    To operate as a validator node, an individual or organization must possess sufficient computing power and energy resources, typically in the form of cryptocurrency mining hardware such as ASICs (Application-Specific Integrated Circuits) or GPUs (Graphics Processing Units). The energy consumption required for these nodes is substantial, making them difficult to maintain on a short-term basis.

    Key Players

    Several key players have emerged in the validator node market, including:

    • Binance: One of the largest cryptocurrency exchanges in the world, Binance has also invested heavily in its own validator node infrastructure.

    • Huobi: Another major cryptocurrency exchange, Huobi has established its own validator node network to support its users’ transactions.

    • Chainlink Labs

      : A company that provides decentralized data feeds and nodes for various blockchain networks, including Ethereum and Binance Smart Chain.

    Conclusion

    The validator node market is a critical component of the cryptocurrency ecosystem. These nodes play a vital role in maintaining the security and integrity of blockchain networks, and their energy consumption can have significant environmental impacts. As the cryptocurrency market continues to evolve, it will be interesting to see how validators adapt to new technologies and strategies, such as proof-of-stake (PoS) consensus algorithms, and how they navigate the challenges associated with energy consumption and scalability.

  • Bitcoin: Handling Multi-Signature Transactions with PSBT in Bitcoin

    Handling Multi-Signature Transactions with PSBT in Bitcoin: Best Practices

    In Bitcoin, a multi-signature transaction is one in which multiple parties must sign a transaction before it can be confirmed and added to the blockchain. Partially Signed Bitcoin Transactions (PSBTs) are a convenient way to represent such transactions, but they require careful handling due to their complex cryptographic structure.

    What are PSBTs?

    A PSBT is a binary representation of a Bitcoin transaction that includes all the data required for signing, including sender information, recipient information, and transaction amounts. It is essentially a compact representation of a Bitcoin transaction, allowing for the efficient storage and transfer of these transactions on the blockchain.

    Benefits of Using PSBT

    PSBTs offer several advantages over traditional signed Bitcoin transactions:

    • Storage Efficiency: PSBTs store all the necessary data in a single binary file, making it easier to store and transfer.
    • Faster Transaction Confirmation: By signing transactions from multiple parties, PSBTs can enable faster transaction confirmation times.
    • Improved Security: The use of signatures provides an additional layer of protection against malicious actors attempting to manipulate or modify the transaction.

    Transacting Multi-Signature Transactions with PSBT

    To manage multi-signature transactions using PSBT, follow these best practices:

    1. Configure the PSBT Client Library

    The command line tool “psbt” is a popular choice for working with PSBT on Bitcoin. You can install it using pip: pip install psbt.

    2. Create a new transaction

    Create a new transaction using the psbt create command:

    psbt create --from your-username@example.com --address my-pallet-address -txnb your-tx-number

    Replace your-username, my-pallet-address, and your-tx-number with your actual wallet information.

    3. Create a PSBT file

    The generated transaction will be stored in a binary file named psbt-file.psb. You can use the psbt file-to-binary command to convert this file to a usable format:

    psbt file-to-binary psbt-file.psb -o psbt.bin

    4. Sign transactions

    To sign transactions with multiple parties, create separate PSBT files using the same transaction data and add them to your wallet as part of a single psbt command:

    Example: signing two parties

    Sign two parties, Alice and Bob, with their respective public keys:

    psbt create --from alice@example.com --address my-pallet-address -txnb 1000 your-tx-number

    psbt create --from bob@example.com --address my-pallet-address -txnb 2000 your-tx-number

    5. Handle signatures

    To To verify the authenticity of a transaction, you need to include a signature in the PSBT file. You can do this using the psbt sign command:

    psbt sign psbt.bin --from alice@example.com --signing-prompt username --address my-signing-address -txnb 1000 your-tx-number

    Example: Verifying a Transaction

    To verify a specific transaction, use the psbt verify command:

    psbt verify psbt-file.psb -username -my-signing-address -txnb your-tx-number

    By following these steps and best practices, you can efficiently handle multi-signature transactions using PSBTs in Bitcoin.

  • Ethereum: Is there a way to pass parameters and headers using Net::HTTP in Ruby?

    I can guide you through creating an article on how to pass parameters and headers using Net::HTTP in Ruby.

    Introduction

    In this article, we will explore the use of Net::HTTP in Ruby to send HTTP requests with custom parameters and headers.

    Passing Parameters Using Net::HTTP

    Net::HTTP provides a params method that allows you to set key-value pairs for your request. Here’s an example:

    require 'net/http'










    Set the URL and headers for our request

    url = '

    headers = { 'Authorization' => 'Bearer YOUR_BEARER_KEY', 'Content-Type' => 'application/json' }


    Create a new HTTP request object with parameters

    req = Net::HTTP.new(url, 443)

    req.use_ssl = true

    params = {

    'key1' => 'value1',

    'key2' => 'value2'

    }


    Set the headers and parameters for our request

    req.set_param('param1', params[:key1])

    req.set_header('param2', headers[:Authorization])


    Send the request with the custom headers and parameters

    row = req.get

    puts res.body

    Passing Headers Using Net::HTTP

    Net::HTTP also provides a set_header method that allows you to set specific headers for your request. Here’s an example:

    require 'net/http'


    Set the URL, headers, and parameters for our request

    url = '

    headers = { 'Authorization' => 'Bearer YOUR_BEARER_KEY', 'Content-Type' => 'application/json' }

    params = {

    'key1' => 'value1',

    'key2' => 'value2'

    }


    Create a new HTTP request object with headers and parameters

    req = Net::HTTP.new(url, 443)

    req.use_ssl = true


    Set the headers for our request

    req.set_header('X-User-Agent', 'My Ruby App')

    req.set_header('Content-Type', 'application/json')


    Send the request with custom headers

    row = req.get

    puts res.body

    Example Use Case: Passing Parameters and Headers using Net::HTTP

    Here’s an example of how you can use Net::HTTP to send a request to the Binance API:

    require 'net/http'

    def get_binance_data(key, value)


    Set the URL for the Binance API

    url = '


    Create an HTTP request object with headers and parameters

    req = Net::HTTP.new(url, 443)

    req.use_ssl = true

    params = {

    'symbol' => key,

    'limit' => value

    }


    Set the headers for our request

    headers = { 'Authorization' => 'Bearer YOUR_BEARER_KEY', 'Content-Type' => 'application/json' }


    Send the request with custom headers and parameters

    row = req.get

    puts "Binance Price: #{res.body}"

    end

    key = 'BTC/USD'

    value = 1000.0

    get_binance_data(key, value)

    Note that this is just a basic example of how to use Net::HTTP in Ruby to pass parameters and headers for your requests. In practice, you may need to handle errors, authentication, and other advanced features depending on your specific use case.

    I hope this helps! Let me know if you have any questions or need further assistance.

  • Ethereum: Can someone with 51% computing power earn more than he deserves?

    Ethereum: Can Someone With 51% of the Computing Power Earn More Than They Deserve?

    The debate over the 51% rule on Ethereum has been going on since the project’s inception. The 51% rule refers to the ability of a powerful group of miners to control more than 50% of the network’s mining power, potentially leading to an attack on the network. But can someone with 51% of the computing power earn more than they deserve?

    The Problem with 51% Power

    When a miner controls more than 50% of the network’s mining power, they become the dominant force in the network’s consensus mechanism. This can give them a significant advantage over other miners and users. For example, if a group of powerful miners were to attack a node on the network, they could potentially control more than 50% of the hashing power, allowing them to manipulate block rewards and transaction fees.

    A Case for 51% Power

    Supporters of the 51% rule argue that it is essential to protect the network from centralization and ensure that all miners have an equal say in decision-making. By limiting the number of miners to 51% power, they argue that the network will be more resilient to attacks.

    However, critics argue that the 51% rule is too restrictive and could lead to censorship and unfairness on the network. They point out that a group of influential miners could simply opt out of the majority decision-making process or use their collective power to manipulate transactions without affecting others.

    Ethereum 51% Rule

    In February 2021, Ethereum updated its protocol to include a hard fork to prevent exactly this scenario from occurring. The new rule limits miners to holding more than 1 million ETH (about $5.7 billion at the time) in their wallets, significantly less than the original 2 million ETH required to secure the network.

    Can someone with 51% power earn more than they deserve?

    While the new rule provides some protection against centralization, it does not eliminate the risk entirely. A group of powerful miners could still attempt to manipulate the network through other means, such as exploiting bugs or using their collective power to control more than 50%.

    However, the new rule significantly reduces the likelihood that a miner will attempt to exploit these vulnerabilities.

    Conclusion

    In conclusion, while someone with 51% of the computing power can potentially earn more than they deserve if they are not careful, it is unlikely that they will be able to do so without facing significant risks and consequences. The new rule provided by Ethereum aims to mitigate these risks and protect the network from centralization, but there are still concerns about its effectiveness.

    Ultimately, the debate over 51% power is still ongoing, with supporters and opponents making valid arguments on both sides. As the ecosystem continues to evolve, it will be interesting to see how this issue is addressed in the future.

  • Ethereum: Foundry script: balance mismatch of tx caller

    Ethereum Foundry Script: Balance Mismatch Error

    As a developer working with Ethereum smart contracts, it is essential to ensure that your scripts are working properly and are accurately tracking account balances. However, there are often oversights that can lead to issues such as balance mismatch. In this article, we will delve into the “balance mismatch” error in Foundry and provide guidance on how to reproduce and resolve it.

    What is a balance mismatch?

    A balance mismatch occurs when the actual balance of an account on the blockchain differs from its displayed balance as shown to the caller of the function used to track the balance of that account. This can happen for a variety of reasons, including:

    • Broadcasting incorrect transactions
    • Conflicting balances between accounts (e.g. due to reentrancy attacks)
    • Incorrect contract code or logic

    Reproduction of foundry scripts

    The following foundry script demonstrates a balance mismatch error:

    MyContract contract {

    fn myFunction() -> Balance {

    // Simulating some transactions

    let tx1 = Tx::new(&[Address::from(0x123456789)), 100);

    let tx2 = Tx::new(&[Address::from(0x234567890)], 200);

    foundry_script {

    vm.startBroadcast(Address::from(0x345678901));

    vm.gather();

    Balance::new().balance() // Should return the caller's balance

    .if_eq(expectedBalance);

    expectedBalance

    }

    }

    fn myFunction2() -> Balance {

    let tx1 = Tx::new(&[Address::from(0x123456789)], 100);

    foundry_script {

    vm.startBroadcast(Address::from(0x234567890));

    vm.gather();

    let balance = expectedBalance;

    assert!(balance.balance().if_eq(expectedBalance));

    balance

    }

    }

    fn myFunction3() -> Balance {

    let tx1 = Tx::new(&[Address::from(0x123456789)], 100);

    foundry_script {

    vm.startBroadcast(Address::from(0x234567890));

    vm.gather();

    let balance = expectedBalance;

    assert!(balance.balance().if_eq(expectedBalance));

    balance

    }

    }

    fn expectBalance() -> Balance {

    // Returns the expected balance based on some logic (e.g. a fixed value)

    Balance::new().balance()

    }

    }

    In this script, we have three functions myFunction, myFunction2 and myFunction3 that simulate transactions and track their balances. The error occurs when calling these functions from the foundry_script file. Specifically, the vm.startBroadcast() function is called with an address as a parameter, but the caller of this function does not have the same balance.

    Why does this error occur?

    The problem arises because foundry_script expects the account to be in a specific state (e.g., not yet broadcasted). However, when calling these functions from foundry_script, the caller’s address has already been broadcasted. As a result, vm.startBroadcast() does not return an empty address, which leads to incorrect balances being tracked.

    Solution: Use vm.startCall

    To fix this error, we need to use vm.startCall instead of vm.startBroadcast. Here is the updated script:

    “`rust

    contract MyContract {

    fn myFunction() -> Balance {

    // Simulate some transactions

    let tx1 = Tx::new(&[Address::from(0x123456789)], 100);

    let tx2 = Tx::new(&[Address::from(0x234567890)], 200);

    vm.startCall(Address::from(0x345678901))

    .withArg(tx1)

    .withArg(tx2)

    .build().unwrap();

    }

    fn myFunction2() -> Balance {

    let tx1 = Tx::new(&[Address::from(0x123456789)], 100);

    vm.startCall(Address::from(0x234567890))

    .withArg(tx1)

    .build().

    What are GUI Miners?

    GUI Miners, also known as graphical miners, use a graphical user interface (GUI) to mine cryptocurrencies. They rely on the GPU’s ability to perform complex mathematical calculations to solve mathematical problems that are used to validate transactions and create new units of the cryptocurrency. The most well-known GUI Miner is Ethereum Mining, specifically using its original algorithm to mine Ether (ETH).

    What are BitMinters?

    BitMinters, on the other hand, use a centralized mining pool to mine cryptocurrencies. Unlike GUI Miners, BitMinters do not require any special hardware or software to operate. Instead, they rely on the collective power of many computers around the world to solve mathematical problems and validate transactions.

    GUI Miner Hardware Requirements

    To get started with GPU mining, you will need a powerful computer with a high-performance graphics card (GPU). When it comes to Ethereum mining, here are some general guidelines:

    • AMD Ryzen 5 1600 or higher
    • Intel Core i5-2400 or higher
    • 8 GB or more RAM

    Hardware Requirements for BitMinters

    BitMinters do not require any specific hardware configuration other than a standard desktop computer. However, to optimize performance and reduce costs, you can use:

    • A high-performance processor (e.g. Intel Core i7-9700K or AMD Ryzen 9 3900X)
    • A fast storage drive (SSD)
    • A decent internet connection for mining

    GPU vs. CPU: Which is better?

    When it comes to mining cryptocurrencies, both GPUs and CPUs can be viable options. However, the choice depends on your hardware configuration, budget, and personal preferences.

    • GPU: Typically, high-end GPUs (e.g. NVIDIA GeForce GTX 1080 Ti or AMD Radeon RX 580) can produce more hashes per second (mhash/s) than low-end CPUs.
    • CPU: Conversely, lower-end CPUs (e.g. Intel Core i5-8300H) can keep up with the hash rate of high-end GPUs.

    7 mhash/s GUI Miner vs. 0.3 mhash/s using BitMinter

    Now that we’ve covered the basics, let’s dive into your experience using both platforms.

    In our example, you mentioned that you use Ethereum as your cryptocurrency of choice and are getting a 7 mhash/s GPU miner. However, when you switch to BitMinters, you only reported 0.3 mhash/s.

    There are a few reasons for this discrepancy:

    • Hash Rate: Hash Rate is the rate at which your mining rig creates new hashes compared to its total computing power. A higher hash rate means that more coins can be mined per unit of time.
    • Mining Pool: BitMinters uses a centralized mining pool, while GUI Miners operate independently. This means that the combined hash power of multiple miners is typically greater than the power of any individual miner.
    • Network congestion: With larger mining pools like BitMinters, network congestion can occur if too many miners are competing for resources at the same time. This can lead to a decrease in hash rate and an increase in the difficulty of finding new hashes.

    Conclusion

    In summary, while GUI Miners and BitMinters offer unique advantages and disadvantages when it comes to mining cryptocurrencies, the choice ultimately comes down to your hardware configuration, budget, and personal preference.

    If you’re looking for a high-end GPU setup, 7 mhash/s hashrate can be achieved with a well-tuned system. However, if you prefer a centralized mining pool with easier to manage network congestion, BitMinters is a great option.
