Bitcoin News posted on X that Libbitcoin developer @evoskuil said the latest Libbitcoin Server can complete Bitcoin full-node initial block download and full verification in 55 minutes. According to Odaily, he said the speed improvement comes from a new GPU-based signature verification system that runs in parallel with standard script verification instead of as a separate step.
He said the software does not pause to verify each ECDSA and Schnorr signature, but instead captures signature checks, batches them, and processes them on the GPU while the rest of verification continues. @evoskuil said the method can capture about 99.5% of signatures without blocking verification, eliminating the need for a second verification pass.
If a batch signature check fails, the software traces it back to the corresponding block and marks that block as invalid. He also said the design can batch nearly any number of signatures, keeping the GPU ahead of the rest of the verification process and significantly reducing full-node sync time.
