In July of last year, the 92 respondents named in the arbitration registered accounts with BitMart before carrying out a 51% attack of the BSV blockchain. In this type of attack, users take over the mining capabilities of a blockchain, leveraging more than half of the mining power, which allows them to mine faster than other users and affect transactions.
