In the Bitcoin  system, transaction data is bundled into a block and broadcasted throughout the entire network. Upon hearing the broadcast, miners begin to calculate a difficulty puzzle, the answer to which needs to meet certain conditions, such as the answer must be a hash value starting with 0. Miners compete to solve this puzzle, and the first successful miner receives a certain amount of Bitcoin as a reward, while his solved block (solved block) is added to the blockchain, forming a new block.↵↵This mechanism ensures the security and integrity of the blockchain, as it requires a significant amount of computational effort to solve the puzzle. Moreover, the difficulty of the puzzle is automatically adjusted by the network to maintain a consistent mining rate, which prevents the network from being overwhelmed by too many transactions or malicious attacks."}]}],"pr":"bb43faf1db66c5bfa9f1df52667a08fa28bbf5d0d263e758ec72e0ead127d55d"}
