Firstly, transactions are bundled into blocks and then propagated through the network for other nodes to validate. During the validation process, nodes utilize consensus algorithms (such as proof of work (PoW) or proof of stake (PoS))  to confirm the legitimacy of transactions. Once a block is recognized and added to the blockchain by the majority of nodes, the transaction is considered confirmed.↵↵Transaction finalization is completed after the blockchain reaches a certain level of confirmation. Generally, when a block is added to the blockchain, the transactions contained in it are considered final."}]}],"pr":"bb3655837298cba591ff5add2a4d4a58cacdab78f43a73c4d77b75757ecc94ea"}
