One of the core components of Bitcoin is the Digital signature algorithms, it is used in making public keys out of private keys, signing transactions and in multisig transactions. Bitcoin so far has been using Elliptic Curve Digital Signature Algorithm ECDSA, for the past few months developers in the Bitcoin community have been talking about changing this algorithm into another one called Schnorr Signatures.
Schnorr is another signing algorithm that bring multiple benefits to the table. A new BIP was recently submitted by Peter Wuille about the changes that should happen in the future to Bitcoin’s signing algorithm with all the bells and whistles it should bring. The security of Schnorr is easily provable given a certain assumption, this is not the case for ECDSA.
