Bitcoin Optech Newsletter #409 Recap Podcast
Bitcoin developers have proposed a draft BIP for testnet5 to replace testnet4 due to persistent exploitation of the '20-minute rule' (difficulty exception) and monetization of testnet coins. Testnet5 will remove the 20-minute exception, start with a higher minimum difficulty (1 million vs 1), and implement BIP54 rules from block 1. Additionally, LND released v0.21.0-beta featuring production support for simple taproot channels and internal tooling for onion messages.
