Published on Thursday, the paper was penned by developers Gregory Maxwell, Andrew Poelstra, Yannick Seurin and Pieter Wuille. It details how Schnorr multi-signatures can be applied to the bitcoin, and though there’s no guarantee they will ultimately be utilized, this new release could mark an additional step in that direction.
Specifically, the Schnorr concept proposes bundling signatures into one small data entry, rather than having multiple signatures listed individually. This has the result of saving space on the blockchain, enabling it to process more signatures while increasing security, according to the paper.
Security is increased by enabling a multi-signature system, wherein at least two parties need to confirm a transaction for it to process. This limits or prevents malicious parties from launching a transaction on another user’s account.
The paper’s authors note:
“The size of the multi-signature in that case grows linearly with the number of signers. In order to be useful and practical, a multi-signature scheme should produce signatures whose size is (ideally) independent from the number of signers and close to the one of an ordinary signature scheme.”
