Blockchain security (Blockchain security assessment qualification)

3 There is never finalityblockchain securityA checkpoint mechanism is needed to make up for the final blockchain. It is a distributed shared accounting technology. What it needs to do is to allow all parties involved to establish trust relationships at the technical level. 4 It mainly includes: first, implementing information content security management responsibilities. Second, it has technical conditions suitable for its services. Third, it is to formulate and disclose management rules and platform conventions. Fourth, it is to implement a real identity information authentication system. 5

However, there are still many challenges to blockchain security issues. Yu Kequn said that blockchain is still in its infancy. There are many challenges such as the security of cryptographic algorithms, protocol security, use security, system security, etc. Yan Hanbing, director of the National Internet Emergency Center Operation Department, also pointed out that if blockchain wants to occupy an important position in the global economy, it must first solve the security problems it faces. Yan Hanbing pointed out that blockchain security issues include multiple aspects such as.

Even if someone attempts to tamper with a transaction record, their changes will not be accepted by the network because other nodes will have the correct copy of the record. In addition, the encryption technology used in Bitcoin ensures that only the parties involved in the transaction can see the details of the transaction. Protectblockchain securityIn general, blockchain provides a highly secure way to store and transmit data through distributed networks and encryption technology, making it more difficult for data to be tampered with or attacked.

Security risks are one of the important risks faced by blockchain technology. There is a security problem with encryption algorithms in the blockchain system. Although the blockchain is designed to use encryption technology to protect the security of data, once an algorithm loophole appears or is cracked, it will lead to data leakage or tampering. In addition, smart contracts also have security risks. If there are loopholes, they may be maliciously exploited, causing property damage regulatory risks that cannot be ignored in the blockchain.
