A benchmark of Bitcoin full validation sync performance on five different implementations by Jameson Lopp.

BitMEX research developed a fork monitoring tool that can be used to monitor network and protocol upgrades for soft and hard forks for Bitcoin and BitcoinCash. They plan to include different implementations of Bitcoin nodes such as Bcoin, BTCD and Libbitcoin which might be helpful to detect consensus bugs such as CVE-2018-17144 that was discovered last September. They also announced that the source code for the tool will be made available soon.
