On June 12, more than 90% of the computation already supports Taproot’s locked-in upgrades, which means that Taproot will be activated when Bitcoin reaches a block height of 709,632 and also means that the Taproot soft fork upgrades activated in November 2021.
Taproot
Taproot was first introduced in early 2008 as a soft fork of the Bitcoin network to enhance Bitcoin’s privacy and scripting capabilities.
Taproot is a set of entirely new Bitcoin scripting structures that define how to use and collect addresses for Taproot-type transactions. The initial concept came from the MAST (Merkel’s Abstract Grammar Tree) proposed by the Bitcoin founders. Thus, Taproot can be considered a special implementation of MAST. With MAST, Taproot can show only the relevant parts of the contract during transactions. It will bring many significant improvements to how Bitcoin transactions operate, such as reduced costs and increased privacy. It will also lay the foundation for enhanced smart contract capabilities and improved lightning networks.
Taproot includes the Schnorr Signature component and the upgrades for Taproot itself. In Taproot itself, when unlocking the asset with MAST, you only need to expose one of the scripts. Hashes can represent the other logic without exposing any further details.
