Researchers at the Digital Currency Lab at the Massachusetts Institute of Technology (MIT) have developed a solution that can prevent attacks on blockchains, according to The Block.
At the moment, the 51% attack remains the most popular, in which the miner seizes control over more than half of the hash rate, which gives him the opportunity to spend the same cryptocurrency twice. To address this issue, MIT researchers launched Pool Detective last December.
The proxy server connects to 32 separate pools and collects data about their work. During the analysis, experts identify “unexpected behavior or anomalies.”
MIT believes that hackers can use cheap power to attack the blockchain. The researchers plan to expand monitoring of mining pools, tracking not just blocks, but messages in peer-to-peer networks. Their content will allow you to better understand what kind of work the miners will get compared to the expected result. The team also plans to develop a version of Pool Detective, which individual miners will launch for their own protection.
