A Developer Puts Bitcoin Block Verification at 27 Milliseconds and the Full Chain at 17 GPU Years
Proofs now cover blocks 1 through 1,789, and the compute bill to prove the remaining sixteen years of history is the reason nobody has finished.
A developer working on Hazync, a project applying zero-knowledge proofs to Bitcoin's chain history, reports verification times of about 27 milliseconds per block for the range already proved, blocks 1 through 1,789. The proving campaign for…

Statelessness Replaces Re-Execution as the Scaling Path
Major chains keep shifting from every-node re-execution toward proof-carrying, stateless verification, so the contest over scaling moves into proving-system engineering and the cost of running an independent node becomes the decisive measure of decentralization.

17 GPU years parallelizes to roughly 6 days across 1,000 GPUs, so the barrier to proving the full chain is upfront compute budget rather than calendar time.
