Network for decentralized threshold cryptography and end-to-end…
NuCypher is one of two founding teams of the Threshold Network, which hosts tBTC, TACo, Random Beacon & tUSD. Since 2017, NuCypher has pioneered cryptographic primitives for end-to-end encrypted data sharing, including Proxy Re-Encryption and Threshold Access Control (TACo), novel cryptoeconomic mechanisms (e.g. Stable Yield). and original network/governance architectures (including a historic on-chain merger). TACo, our flagship product, is running on over 120 nodes with ~$80m of associated economic security, has paying adopting developers and major infrastructure partners (Ceramic, Irys, Textile, Unlock), and has been decentralized from genesis (mainnet launch in Jan 2024).
Threshold Network (NuCypher) provides a Bitcoin-focused infrastructure that enables verifiable Bitcoin accounts and on-chain access to Bitcoin liquidity for institutions, protocols, and developers. It positions itself as the standard for Bitcoin finance by offering programmable, secure, and transparent access to Bitcoin capital markets via threshold cryptography and tBTC.
Threshold Network uses threshold cryptography to enable verifiable Bitcoin accounts and tBTC, a bridge that allows Bitcoin to be used across DeFi and on-chain markets. It provides secure, scalable access to Bitcoin capital markets with direct BTC deposits/withdrawals, composable SDKs for integration, on-chain proof of reserves, and options for lending, staking, trading, and yield generation backed by institutions and professional operators.
Who it’s for: Institutions, protocols, and developers seeking programmable, secure access to Bitcoin liquidity and on-chain capital markets; users requiring permissionless DeFi participation with custody standards maintained.

Meet tBTC, a decentralized, permissionless, scalable BTC bridge to DeFi
tBTC is a decentralized, trust-minimized BTC bridge that mint tBTC by depositing BTC with the Threshold Network, enabling BTC to be used permissionlessly in Ethereum DeFi for activities like lending, borrowing, and liquidity provisioning. It targets BTC holders and DeFi users seeking a non-custodial, centralized-bridge alternative.
