Solana (SOL-USD) climbed 11.4% to $215.40 on Thursday, a fresh year-to-date high, after Jump Crypto subsidiary Jump Trading activated the long-anticipated Firedancer validator client on Solana mainnet at 14:00 UTC. Initial network telemetry from Solana Beach showed sustained throughput averaging 12,400 transactions per second over the first five hours of operation, with peak bursts above 18,000 TPS during a coordinated stress test.
Firedancer — written from scratch in C and Rust — represents the second independent validator implementation on Solana alongside the original Anza client. Roughly 18% of stake is now operating on Firedancer at activation, with Jump Crypto president Kanav Kariya telling Bloomberg the company expects 40% stake migration by end of Q3. The architectural diversification has been a long-standing investor concern given the network's history of multi-hour outages between 2021 and 2023.
