Fork (blockchain)
In blockchain, a fork is defined variously as: * "What happens when a blockchain diverges into two potential paths forward", * "A change in protocol", or * A situation that "occurs when two or more blocks have the same block height". Forks are related to the fact that different parties need to use common rules to maintain the history of the blockchain. When parties are not in agreement, alternative chains may emerge. While most forks are short-lived some are permanent. Short-lived forks are due to the difficulty of reaching fast consensus in a distributed system. Whereas permanent forks (in the sense of protocol changes) have been used to add new features to a blockchain, they can also be used to reverse the effects of hacking such as the case with Ethereum and Ethereum Classic, or avert catastrophic bugs on a blockchain as was the case with the bitcoin fork on 6 August 2010. The concept of blockchain technology was first introduced in 2008 by an unknown person or group of pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monero
Monero (; Abbreviation: XMR) is a cryptocurrency which uses a blockchain with privacy-enhancing technologies to obfuscate transactions to achieve anonymity and fungibility. Observers cannot decipher addresses trading Monero, transaction amounts, address balances, or transaction histories. The protocol is open source and based on CryptoNote v2, a concept described in a 2013 white paper authored by Nicolas van Saberhagen. Developers used this concept to design Monero, and deployed its mainnet in 2014. The Monero protocol includes various methods to obfuscate transaction details, though users can optionally share view keys for third-party auditing. Transactions are validated through a miner network running RandomX, a proof-of-work algorithm. The algorithm issues new coins to miners and was designed to be resistant against application-specific integrated circuit (ASIC) mining. Monero's privacy features have attracted cypherpunks and users desiring privacy measures not provided in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
