Classic PBFT-like algorithms Sample Clauses

Classic PBFT-like algorithms. It is interesting to see that most partially synchronous con- sensus algorithms already collect forms of cryptographic ev- idence like signatures or certificates to guarantee agreement must have had the same value as a preparation. During view changes, if 𝑡 < 𝑡0, then a preparation implies a propagation of a value to the leader within messages announcing the new view.
