[Synchronization time reduced to 55 minutes, Libbitcoin Server completes Bitcoin full node initial block download via GPU signature verification] Odaily Planet Daily reports that Bitcoin News posted on the X platform stating that Libbitcoin developer @evoskuil claims the latest version of Libbitcoin Server can complete the initial block download for a Bitcoin full node in 55 minutes 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 as a separate step. The software does not pause execution to verify each ECDSA and Schnorr signature; instead, it captures signature checks, processes them in batches, and handles them via GPU while the rest of the verification continues. @evoskuil stated that this method achieves approximately a 99.5% signature capture rate without blocking verification, eliminating the need for a second verification pass. If batch signature checks fail, the software traces them back to the corresponding block and marks the block as invalid. He also mentioned that the design can batch process virtually any number of signatures, keeping the GPU ahead of the remaining verification process and significantly reducing full node synchronization time.
