TY - JOUR JF - isc-monadi JO - منادی VL - 8 IS - 1 PY - 2019 Y1 - 2019/9/01 TI - A Review of Consensus Algorithms in Blockchain TT - مروری بر الگوریتم‌های اجماع در بلاکچین N2 - Blockchain technology is a decentralized data structure based on a chain to the ledger of interconnected data blocks. Blockchain stores new blocks in the ledger without having to rely on intermediaries in a competitive or voting mechanism. Due to the chain structure or graph between each block and its previous block, it is impossible to modify blockchain data. Blockchain architecture provides trust in a peer-to-peer network through nodes on the network according to different consensus algorithms. In this article, we intend to describe the mechanism of each consensus-based, voting-based, and distant-oriented graph consensus algorithm.
