Telegram proposes consensus algorithm Catchain or reachable theoretical limit of BFT solution

Telegram co-founder Nikolai Durov details Telegram's open network consensus mechanism Catchain in a recently published paper. The solution presented by Catchain is the Byzantine Fault Tolerance (BFT Consensus Mechanism) Proof of Stake (PoS) algorithm, which is similar to the algorithm used by NEO or Cosmos. As long as one-third of the nodes are not malicious, Catchain can work normally, which is equivalent to the theoretical limit of BFT solutions.
