Hazync Validates 1,789 Bitcoin Blocks in 27 Milliseconds with 17 GPU-Year Price Tag

A research prototype called Hazync has made significant progress in validating Bitcoin transactions. According to its developer, Hazync can validate a 226,434-byte cryptographic receipt covering the first 1,789 blocks of Bitcoin in just 27 milliseconds.

This achievement is impressive, but it comes with a caveat - the process requires an enormous amount of computational power. The developer estimates that it would take approximately 17 GPU-years to complete a genesis-to-tip proof campaign for Bitcoin.

Hazync uses RISC Zero's zero-knowledge virtual machine (zkVM) to make Bitcoin validation reusable. The zkVM executes the validation program, and the resulting receipt gives other users a compact file to check.
