Abstract generation in progress

Jump Crypto’s Firedancer validator client has gone live on the Solana mainnet after roughly three years of development, marking a major step toward Solana’s long-term goal of supporting up to one million transactions per second (TPS) in real-world conditions.

It was activated after over 100 days of continuous testnet operation on a handful of validators, producing more than 50,000 blocks without major issues.

Firedancer is a high-performance, C/C+±based validator client for Solana built as a full alternative to Solana Labs’ original Agave client.

A production-ready alternative reduces the risk that a bug in one implementation could halt the entire network

Earlier this year, a hybrid client known as “Frankendancer,” which combines elements of Agave and Firedancer, entered beta testing. Blockworks data shows more than 26% of validators now running it — a possible early signal of Firedancer gaining momentum.
