How it works
Before the latest evolution of tBTC, Bitcoin to Ethereum bridges used a centralized model that required users to send their Bitcoin to an intermediary. tBTC doesn’t require users to trust a third party — it’s secured by the Threshold network. Formed by the first ever on-chain merger between the Keep and NuCypher networks, the Threshold Network is a set of protocols and the node operators that back them. Threshold cryptography distributes operations across a network of independent nodes, protecting data and reducing reliance on third parties.
