Analyze Bitcoin-NG, PeerCensus and BizCoin

and conluced that none of them is safe in an adversarial environment, and amplify the ability of malicious users

Stellar Consensus Protocol, Avalanche

Avalanche can be viewed as a randomized realization of the Stellar Consensus Protocol

In the lens of classical consensus protocol

Updates recorded in the ledger are immutable, with cryptographic time-stamping to achieve serializability
