Too Long; Didn't Read
Digital signatures are an essential building block of the Bitcoin protocol and account for a large part of the data stored on the blockchain. We detail how the size of the encoded ECDSA signatures has been reduced multiple times over the last years and how the proposed Schnorr signature compares to the length of the currently used signatures. The signatures on the Bitcoin blockchain are nearly evenly split between 72 and 71 bytes in length between December 2015 and early 2018. Starting December 2015, nearly all transactions on the. blockchain have only low-s values in their signatures.
