In a blockchain system, transaction version refers to the updating and adjustment  of data in the blockchain according to different versions of transaction protocols. To set the maximum supported transaction version, several aspects need to be considered:\\n\\n1. Consensus Algorithm: The consensus algorithm in a blockchain system determines how nodes reach agreement with each other, thus deciding the data in new blocks. Common consensus algorithms include Proof of Work (PoW), Proof of Stake (PoS), and Byzantine Fault Tolerance."}]}],"pr":"9b6b93e9deab0ebf3846104171f6df983ea2c3d50f637ce8feea9d09c7d22bf7"}
