In the process of validating a block by block producers(at least 15 block producers should validate and agree – knowledge taken by technical paper). How can they communicate with each other that they are validated a block and agreed?
Did they follow the YES/NO strategy or they share more information of block they validate?
All the process of communicating and validating blocks is done in the eosio code by the concensus
“A consensus mechanism is a fault-tolerant mechanism that is used in computer and blockchain systems to achieve the necessary agreement on a single data value or a single state of the network among distributed processes or multi-agent systems.”
You can see the codes for the chain they are running there: https://github.com/EOSIO/eos/blob/master/libraries/chain
