  • Bitcoin Core released upgrade v0.19.0.1 on November 24th. The upgrade provides a few new RPC enhancements, updated settings for whitelisting, and added a new setting for block filters. The new block filters enable the creation of BIP158 filters for the entire chain. Ethereum:

  • The BitcoinCash network upgrade activated on November 15th. The upgrade features two new advancements. The first is that now all signature checking operators support Schnorr signatures. The second feature removed the BIP62 malleability vector which means that most of the transactions on the BCH network are now non-malleable. There is now no way that transactions can be modified in-flight without validation. BIP62 originally allowed a transaction on the Bitcoin blockchain to be malleable in multiple ways, allowing a valid transaction to be modified in-flight without invalidating it.
