There are a number of ways to solve the 'Byzantine general’s problem'. One way is to use a 'voting system', where each general casts a vote for or against the proposed plan. If a majority of the generals vote in favor of the plan, then it is adopted. If there is a tie, then the vote is repeated.

Another way to solve the Byzantine general’s problem is to use a 'consensus system', where each general agrees to a plan if a majority of the other generals also agree to it.

Use of 'digital signatures'. Each general can sign their message with their private key & then other generals can verify the signature with the corresponding public key. This way, they can be sure that the message came from the correct sender.

Use of a 'distributed ledger', such as a 'TimeChain'. With a Timechain, each general can send their message to every other general & then everyone can agree on the order of the messages. This way, even if some of the generals are malicious, the correct message will still be agreed upon.
