Mining is an important component of the blockchain system, which verifies transactions and creates new blocks by solving mathematical problems. However, there is a security risk called the 51% mining attack, where attackers can manipulate blockchain data or prevent the generation of new blocks by controlling more than 50% of the computing power. This attack poses a serious threat to the security of blockchain.\n\nAnother incentive mechanism in blockchain networks is endorsement rewards, which aims to encourage participants to verify transactions and protect network security. Endorsement nodes validate transactions to ensure that they meet the requirements of the blockchain protocol, and thereby secure the overall security of the network."}]}],"pr":"34f8120b4c65b2fcd6e5b71a20ad7f802d4a6c962eae13a73c25f5c1f281ed0b"}
