Recently, the World Economic Forum (WEF) released a report on the security of blockchain networks. The report pointed out that most data breaches are not the high-end technology level of hackers, but the lack of corresponding security measures. It is more willing to try to exploit or destroy the deployment of the blockchain than the attacker destroys the blockchain. The report also pointed out that cybersecurity should be regarded as a core leadership discipline. The World Economic Forum recommends that the head of the blockchain-related company should establish a cybersecurity leadership position and ensure that the position has sufficient power to take corresponding strong measures. .
