Threshold Network

Threshold Network is a set of protocols and the node operators that back them to offer a full suite of decentralized threshold cryptography services. Threshold cryptography protects data by distributing operations across a network of independent nodes. This simple idea increases security and availability and reduces reliance on trusted parties. It was formed by the first ever on-chain merger between the Keep and NuCypher networks.



Keep was a privacy layer for Ethereum. A “keep” is an off-chain container for private data. Keeps help contracts harness the full power of the public blockchain — enabling deep interactivity with private data. The Keep network, powered by KEEP tokens, handled custodianship for tBTC v1. It has been superseded by the Threshold Network for tBTC v2, an upgraded, more scalable, and more efficient version of tBTC operated by Threshold since 2022.
