Performance

Charts below present system memory and time needed to sync BTC block chain up to the given block number.

Note:
Gocoin uses (configurable) LastTrustedBlock to avoid verifying scripts from all blocks known as valid.
Referenced Bitcoin Core uses an identical mechanism (configurable with assumevalid parameter).
Both implementations come with a recent trusted block built into their code (no need to configure them explicitly).

Gocoin 1.11.0, built with Go 1.23.4

Benchmarks were run on Hetzner dedicated server with 3.2GHz Intel i7-8700 CPU, 128GB RAM, 2x1TB SSD and 1Gbit internet connection, running Debian 12 (bookworm).
