These participants are called nodes, which share, copy, and synchronize data through distributed ledger technology to ensure the consistency and immutability of data in the blockchain network. When nodes receive new transactions or blocks, they need to first verify their correctness, then add valid transactions to their local ledgers and propagate them to adjacent nodes. This process is jointly completed by all nodes in the blockchain  network, achieving the maintenance and recording of consensus rules."}]}],"pr":"fcec8af78ab1b981cef4912f79d0a09d870b5539fde4a8fa1bc59b0abf120a16"}
