Bitcoin (BTC) developer Pieter Wuille has unveiled two proposals on GitHub for a Taproot soft fork in a message to the bitcoin-dev mailing list on May 6.
Taproot is a solution that aims to combine the advantages of Merkelized Abstract Syntax Tree (MAST) and the Schnorr signature scheme in order to reveal less information after a bitcoin transaction takes place.
MAST allows for the alternative possibilities of how a bitcoin transaction could have occurred to remain private, and Schnorr allows for a MAST-enabled transaction to occur without revealing that MAST was used to check transaction conditions. Schnorr signatures enable wallet software to use key aggregation/thresholds within one input.”
As Cointelegraph has previously covered, privacy is a feature of bitcoin that is expected but in actuality does not exist to a high degree.
