In chain news, the Bitcoin network is expected to undergo a Taproot soft fork upgrade in 24 hours (at block height 709632) at the current Bitcoin block-out rate.Taproot, announced by Bitcoin Core developer Greg Maxwell in 2018, will be able to significantly increase the flexibility of Bitcoin smart contracts by combining the Schnorr signature with the Merkle Abstract Syntax Tree (MAST) and Tapscript's new scripting language, which can dramatically increase the flexibility of Bitcoin smart contracts while enhancing Bitcoin's privacy and scalability.
