According to U.Today, Ethereum founder Vitalik Buterin believes that the 51% attack problem can be solved by timeliness detectors. The new concept proposed by V God solves three challenges because it allows active blockchain users to agree on three crucial issues:
1. Whether a "serious enough" 51% attack has occurred;
2. What is the "correct" chain to aggregate;
3. Which validators are responsible for the attack. This analysis will be performed by randomly selected validators. Relevant personnel will check the timestamp of each block to see if it produced the block "on time". Therefore, only those blocks that are "on time" will be rebroadcasted to the mainnet through the verifier's signature.
