Blockchain Consensus Algorithms

Algorithm

⎊ Blockchain consensus algorithms represent the procedural mechanisms by which a distributed network achieves agreement on a single, consistent state of data, crucial for maintaining integrity within decentralized systems. These algorithms mitigate the risks associated with distributed ledger technology, specifically addressing the ‘Byzantine Generals’ problem where participants may act maliciously or fail. Proof-of-Work, Proof-of-Stake, and Delegated Proof-of-Stake are prominent examples, each employing different methods to validate transactions and create new blocks, impacting network security and scalability. The selection of a specific algorithm influences transaction throughput, energy consumption, and the level of decentralization achieved, directly affecting the viability of cryptocurrency and derivative applications.
