Overview

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).
