Ethereum developer Tim Beiko published an article describing some changes after the Ethereum merger. First, the block time has been reduced from 13 seconds to 12 seconds. Second, a block needs to be confirmed by 2/3 of the nodes before it is finally recognized. If an attacker wants to create a fork, he needs to burn at least 1/3 of the stake, which costs more than 2.5 million ETH. Third, some information in the block header is set to 0, including the difficulty value, sequence value, and hash value representing the uncle block list, which are unique to POW. Fourth, the original code for calculating the mining difficulty (0x44) will be replaced by a random number. This change can be used to determine whether the smart contract has been upgraded to POS. If the return value is greater than 2**64, it means that it is indeed executed on POS.

The 360 ​​Threat Situation Monitoring System has developed a "mining" monitoring and disposal function, which can form a normalized "mining" monitoring mechanism from the regulatory side, the enterprise side, and the city side. According to the monitoring data of the 360 ​​Threat Situation Monitoring System in November, the average daily number of active mining host IPs is 109,000, and the main network types used are home broadband, enterprise dedicated lines, and data centers, mainly distributed in Guangdong, Jiangsu, Zhejiang, Shandong and other places in my country.

360 implements full-cycle monitoring and analysis of "mining" activities, which can be summarized into the following three stages: the first stage is pre-investigation. It provides the total IP amount, risk level, and activity trend of mining hosts using data centers, enterprise dedicated lines, organizations and other network types across the country, provinces, cities, districts and counties, helping regulatory agencies and corporate institutions to grasp the activity status of mining hosts in real time; the second stage is in-process investigation. Based on the priority of regional mining host events, it provides detailed reports such as threat profiles, family gangs, duration, number of connections, and disposal suggestions involved in the event to assist regulators and corporate units in issuing disposal; the third stage is post-verification. The 360 ​​threat situation monitoring system continuously provides monitoring capabilities, tracks event disposal results, verifies and evaluates regulatory effects, and forms a closed-loop regulatory system.
