Pico 3.1 is live. Real-time Ethereum proving, still on a single machine with 4 GPUs, and now with:

✅ 128-bit provable security
✅ final proofs of 300 KB or less
✅ fully open source, CPU and GPU, under MIT and Apache 2.0

The security level and proof size match the Ethereum Foundation's end-of-2026 targets. And it got a little faster: 99% of blocks proven in 8.73s or less (Pico 3.0: 9.10s).
