According to AMBCrypto, DASH has deployed Chainlock, which enables instant settlement and rapid re-use without any risk to the payee and reduces the 51% attack on DASH. Chainlock will randomly select 400 nodes to form arbitration through the master node. When 60% of the nodes agree to verify, the limited period of the newly generated block will be confirmed and added to the main network. Dash Core Group CEO Ryan Taylor said that "the cost of attacking the Dash network for an hour is not just to rent a certain hash value like attacking other cryptocurrencies, you must also control 20% to 25% of the bitcoin supply in order to try. It may make Dash the safest cryptocurrency, even more than Bitcoin."
