Jump Crypto’s Firedancer validator client has gone live on the Solana mainnet

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.
