A single signature is produced for each one, which differs from multi-sig (and similar) script implementations in Bitcoin that require several independent digital signatures. It also means that this single signature mechanism can be used on any ECDSA signature chain, irrespective of if the chain natively has multi-sig capabilities or not. ECDSA signatures are typically around 72 bytes per signature, where as Schnorr signatures are a maximum length of 64 bytes. This gives us about a 12% reduction in signature size. The use of Schnorr signatures in single signature transactions would help clear up a little more space for more transactions, but only slightly. Schnorr helps in this respect, but this isn’t what excites the Bitcoin ... User Guide of Threshold Signature Scheme (TSS) in Binance Chain Introduction. Threshold Signature Scheme (TSS) is a cryptographic protocol for distributed key generation and signing. TSS allows constructing a signature that is distributed among different parties (for example three users), and each user receives a share of the private signing key. To sign a transaction, at least two of these ... Digital Signatures (ECDSA). The algorithm for digital signatures used in Bitcoin is Elliptic Curve Digital Signature Algorithm, or ECDSA, based on the mathematics of elliptical curves for coupling private and public keys, which uses the script functions OP_CHECKSIG, OP_CHECKSIGVERIFY, OP_CHECKMULTISIG, and OP_CHECKMULTISIGVERIFY. ^ "RFC 6979 - Deterministic Usage of the Digital Signature Algorithm (DSA) and Elliptic Curve Digital Signature Algorithm (ECDSA)". Retrieved February 24, 2015. ^ "The Double-Base Number System in Elliptic Curve Cryptography" (PDF). Retrieved April 22, 2014. ^ Bendel, Mike (December 29, 2010). Your private key is your passport to the Bitcoin network. It’s what allows you to generate an address for receiving coins, and what later allows you to spend them. In this article, we’ll take a look at the Schnorr signature algorithm, an alternative to ECDSA that could bring some exciting changes in Bitcoin. A brief recap on digital signatures

Pieter Wuille, Bitcoin Core Developer and Blockstream Co-Founder, spoke about Key Tree Signatures. Bitcoin supports multisig transaction outputs, which require more than a single signature to unlock.
