Protocol upgrade decouples consensus from execution to solve scaling bottlenecks
High-performance blockchains often hit a bottleneck when transaction execution sits inside consensus: validators must execute blocks before confirming them, so heavier smart contracts and state updates slow the whole network. MultiversX’s Supernova, live on testnet, removes that constraint by decoupling consensus from execution. Proposers now submit blocks without pre-executing transactions, validators vote immediately, and execution happens asynchronously, with results usually notarized in the next block header about one block later. To keep this safe, Supernova adds a virtual mempool that tracks pending nonces, balances, and unconfirmed proposed transactions so future blocks remain likely to execute validly. It also uses the Execution-Result Inclusion Estimator to limit how many execution results a block can reference, plus automatic backpressure if execution lags. The goal is faster finality and more responsive performance for latency-sensitive apps like DeFi and onchain order books.
