Blockchain Sui's total value of locked positions ( TVL ) has surged from $90 million to $560 million in three months. As of the end of October last year, there were 73 million SUIs in its DeFi protocol, which now exceeds 320 million. Built as a delegated proof-of-interest network by former Facebook/Meta engineers, Sui is said to be positioned as a high-performance blockchain that executes transactions in parallel to improve transaction processing efficiency.
