What Cryptographic Algorithm Is Commonly Used for Implementing a Threshold Signature Scheme?
One of the most commonly used cryptographic algorithms for implementing a Threshold Signature Scheme (TSS) in blockchain oracles is the Boneh-Lynn-Shacham (BLS) signature scheme. BLS signatures are highly efficient because they allow multiple signatures to be aggregated into a single, short signature that can be verified quickly on-chain.
This property is ideal for decentralized oracle networks where many nodes must contribute to a single, verifiable data report.
