Svmuu News: Bitcoin News posted on X that Libbitcoin developer @evoskuil stated the latest version of Libbitcoin Server can complete the initial block download for a full node at Bitcoin and perform a full verification within 55 minutes.This speed boost comes from a new GPU-based signature verification system, which runs in parallel with standard script verification rather than as a separate step.The software does not pause execution to verify each ECDSA and Schnorr signature; instead, it captures signature checks, batches them, and processes them via the GPU while the rest of the verification continues. @evoskuil noted that this method achieves a signature capture rate of approximately 99.5% without blocking verification, thereby eliminating the need for a second verification.If a batch of signature checks fails, the software traces it back to the corresponding block and marks that block as invalid. He also noted that this design can batch-process virtually any number of signatures, keeping the GPU ahead of the rest of the validation process and significantly reducing full node synchronization time.
