The Supernova upgrade on MultiversX has achieved an impressive block finalization time of 88 milliseconds in internal testing. This development positions MultiversX as a leader in blockchain efficiency, with expectations to maintain sub-300ms finalization in real-world conditions. In comparison, other blockchains like Solana and Sui have finalization times ranging from 400 to 800 milliseconds, while Ethereum and Bitcoin have significantly longer times at approximately 12,800 milliseconds and 3,600,000 milliseconds, respectively. The upgrade could significantly enhance transaction speeds and network performance on the MultiversX mainnet.
