TACo (Threshold Access Control) enables end-to-end encrypted data sharing and communication. There is no requirement to trust a centralized authority or entity, who might unilaterally deny service or even (surreptitiously) decrypt private end-user data.
It is currently the only access control layer available to Web3 developers is decentralized from genesis, via the live, well-collateralized, and battle-tested Threshold network. This means access to all data encrypted using a TACo Mainnet DKG public key will be managed by a distributed set of machines, from the very first byte.
All third-party services – digital, Web3 and beyond – impose a trust burden on the user. TACo minimizes this trust burden by disassembling and distributing sensitive cryptographic operations – key generation, access condition verification, and decryption fragment provision – across a large group of independently operated nodes.
