After two years of testnet validation, the Firedancer client developed by Jump Crypto has begun mainnet rollout on selected Solana validators.
Early measurements show a 4.2x throughput improvement on the upgraded subset, with peak block production hitting 8,400 TPS during stress windows tracked by Melega's infrastructure desk.
Network analysts characterize the upgrade as the most material execution-layer improvement to Solana since the Sealevel parallel runtime.
