Firstly, the consensus mechanism adopts methods such as Proof of Work (PoW) and Proof of Stake (PoS) to ensure fair competition among nodes in the network to generate new blocks. In the PoW mechanism, nodes need to solve calculation problems to compete for account rights. The node with stronger computing power has a greater chance of winning the right to generate blocks. This competitive approach requires malicious attackers to invest heavily in computing resources to affect the operation of the blockchain, thereby reducing the probability of malicious attacks.↵↵Secondly, the blockchain employs a distributed ledger technology that stores data across multiple nodes in the network, making it difficult for malicious attackers to manipulate or tamper with the data. Additionally, the blockchain  uses cryptographic algorithms to secure the data, making it virtually impossible for attackers to break into the system.↵↵Lastly, the blockchain ecosystem is constantly evolving, with continuous"}]}],"pr":"f30b34352dedc492d6d9862cf0ab191d2f781c65dc93348142f160a4c07986da"}
