First, sync-time was improved through “Headers First” synchronization, which ensures that new Bitcoin nodes don’t waste time validating (potentially) weaker blockchains. In recent years, sync-time has been improved with “Assume Valid,” an optional shortcut that lets nodes skip signature verification of older transactions, instead trusting that the Bitcoin Core development process in Bitcoin Core 0.21. It took 341 minutes to sync Bitcoin Core 0.21 from genesis to block 655,000 with assumevalid=0 on my benchmark machine. 🚀Endomorphism FTW🚀 — Jameson Lopp (@lopp) November 6, 2020.
