Sync time reduced to 55 minutes: Libbitcoin Server completes Bitcoin full node initial block download with GPU signature verification

Odaily reported that Bitcoin News posted on X platform, stating that Libbitcoin developer @evoskuil claims the latest version of Libbitcoin Server can complete the initial block download of a Bitcoin full node in 55 minutes, along with full verification. This speed improvement comes from a new GPU-based signature verification system, which runs in parallel with regular script verification rather than being executed as a separate step. Instead of pausing execution to verify each ECDSA and Schnorr signature, the software captures signature checks, batches them, and processes them through the GPU while the rest of the verification continues. @evoskuil stated that this method achieves a signature capture rate of approximately 99.5% without blocking verification, thus eliminating the need for a second verification. If a batch signature check fails, the software traces it back to the corresponding block and marks that block as invalid. He also mentioned that 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 synchronization time.
