Proof of Parallel

Every Solana transaction is signed. Checking those signatures is one of the heaviest jobs a validator does, and Solana was built to do it on GPUs. Here one rented gaming GPU checks every signature on Solana mainnet, live.

You are the Solana leader. Tap the real transactions, never the fakes, and see how far one human gets before the GPU takes over. Play full screen

Live: Solana mainnet on one GPU

–

signatures per second on Solana mainnet right now, every one verified on the GPU

– of one RTX 4090's measured capacity (6,759,163 signatures per second)

–signatures verified

–blocks checked

–GPU time per block

–room to grow

How: every confirmed block is pulled from Solana mainnet, every ed25519 signature in it is checked on the GPU with Solana's own open-source verifier (anza-xyz/solana-perf-libs, unchanged). Network rate is the average signatures per block over the last minute times 2.5 blocks per second (400 ms slots).

PoP Score: signatures per second per $1 an hour

GPU	Sigs / sec	$/hr rented	PoP Score	vs CPU

Each GPU rented on vast.ai on 2026-11-05 and measured against the CPU in the same machine (ed25519-dalek on every thread, 1% tampered signatures, every result checked). PoP Score = signatures per second for each dollar per hour. The gaming cards win on value; the RTX 4090 is the fastest card outright.
