Libbitcoin developer @evoskuil said the latest version of Libbitcoin Server can complete a Bitcoin full node’s initial block download and full validation in 55 minutes. He attributed the speedup to a new GPU-based signature verification system that runs in parallel with standard script validation instead of being handled as a separate step. According to his description, the software does not stop to verify each ECDSA and Schnorr signature one by one. It captures signature checks, batches them, and sends them to the GPU while the rest of the validation process continues. @evoskuil said the approach can capture about 99.5% of signatures without blocking validation, removing the need for a second verification pass. If a batch signature check fails, the software traces the failure back to the relevant block and marks that block as invalid. He added that the design can batch nearly any number of signatures, allowing the GPU to stay ahead of the rest of the validation pipeline and sharply reduce full-node sync time.

He said the improvement comes from a new GPU-based signature verification system that runs in parallel with standard script validation rather than as a separate stage.
Under the design he described, the software does not pause execution to verify each ECDSA and Schnorr signature individually. Instead, it captures signature checks, batches them, and processes them on the GPU while the rest of validation keeps moving.
@evoskuil said the method achieves a signature capture rate of about 99.5% without blocking validation, which removes the need for a second verification pass.
If a batched signature check fails, the software traces the failure 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 validation flow and significantly cutting full-node synchronization time.
