The Great Consensus Cleanup
The great consensus cleanup is a new BIP suggested by developer Matt Corallo to address different issues in the current Bitcoin consensus, the new set of consensus changes aim at reducing complexity of Bitcoin implementations, improving worst-case validation times and fixing vulnerabilities like timewarp.
Bitmex Research Launched a Fork Monitoring Website
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.
Accuracy of Bitcoin Timestamps

An interesting thread was started by Neiman via bitcoin-dev regarding the accuracy of Bitcoin block timestamps.

I’m doing a research project about blockchain timestamping. There are many such projects, including the fantastic OpenTimestamps.

I didn’t find any discussion or research regarding Bitcoin timestamp accuracy (also not in the history of this mailing list). I share here a simple analysis of timestamp accuracy, and a suggestion how to improve it.
