Algorithmic consensus in cryptocurrency refers to the agreed-upon protocol that enables the network of computers to reach a consensus on the validity of transactions. This consensus is achieved through a set of rules and procedures known as algorithms that govern how transactions are verified and added to the blockchain.
In a decentralized system like cryptocurrency, there is no central authority that validates transactions. Instead, the network relies on algorithms to ensure that all transactions are legitimate and secure. These algorithms ensure that all participants in the network agree on the state of the ledger and prevent double-spending or fraudulent transactions.
Different cryptocurrencies may use different algorithms to achieve consensus, such as Proof of Work (PoW) or Proof of Stake (PoS). These algorithms ensure that all nodes in the network work together to validate transactions and maintain the integrity of the blockchain. By reaching consensus through algorithms, cryptocurrencies can operate autonomously and securely without the need for a central authority.
