The explosive blockchain gives people unlimited fantasy. When many people think about the benefits of blockchain, one of its problems has aroused people's concern, that is, security. Some time ago, 360 discovered a high-risk vulnerability in the blockchain, which can control all the nodes on the EOS. We all know that 51% of the nodes in the blockchain can tamper with the data, let alone 100%. Let's see what's going on
On May 29, 360 Vulcan team announced that it had discovered a series of high-risk security vulnerabilities of EOS platform. It is verified that some of the vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks.

Blockchain technology is popular in the market because it can rece intermediate links, rece fraud caused by data consistency, improve business efficiency and speed, rece the risk of counterparties, increase revenue and save costs
in-depth study of its implementation principle, blockchain uses cryptography algorithm, specially designed data structure and multi-party consensus algorithm to solve the consistency, reliable storage and anti tampering problems of multi-party transaction records by machine algorithm, which has a strong natural relationship with electronic data storage
first of all, the electronic contract signing records are stored in the shared account book jointly maintained by multiple parties, which can not be tampered with, denied, and of course will not be lost
secondly, electronic contract text and electronic contract elements are encrypted, including electronic contract participants. Only participants can decrypt and view the data to protect the privacy of the parties
thirdly, the machine strictly implements the pre-defined rules (smart contract), and no longer only relies on a single agreement with a third party. KYC service based on blockchain automatically checks and verifies the validity and identity of certificates, and ensures the authenticity of participants' identities on the basis of privacy
in recent years, speculation related to virtual currency (such as ICO, IFO, IEO, IMO, STO, etc.) has become popular, prices have risen and fallen sharply, and risks have gathered rapidly. Relevant financing entities raise funds from investors or virtual currencies such as bitcoin and Ethereum through illegal sale and circulation of tokens. In essence, they are illegal public financing without approval. They are suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal crimes, which seriously disrupt the economic and financial order
on September 4, 2017, the people's Bank of China and other seven ministries and commissions issued the "notice on preventing the financing risk of token issuance", which cleaned up the ICO and virtual currency trading venues. The scale of domestic virtual currency transactions decreased significantly, effectively avoiding the impact of virtual currency prices on China's financial market.
