Action Control

TACo Action Control is currently in alpha and available only on the DEVNET environment.

TACo Action Control enables decentralized, conditional signing of data using threshold cryptography. It allows applications to request signatures from a distributed network of nodes, where signatures are only generated when predefined conditions are met.

Problems Addressed

1. Centralized Signing Authority

Problem: Traditional signing systems rely on a single key holder, creating security vulnerabilities and single points of failure.

Solution: TACo distributes signing authority across multiple nodes using threshold cryptography. No single entity can unilaterally generate signatures, reducing the risk of non-availability, key compromise, or malicious signing.

2. Unconditional Signing Powers

Problem: Once an entity is granted signing authority, they can sign any data at any time without restrictions. Providing unrestricted access to private keys to automated system such as bots or trading agents poses significant security risks.

Solution: TACo allows delegating limited signing authority to automated systems and strictly enforces conditional signing, where signatures are produced only when predefined conditions are independently verified by multiple signers, each and every time. This enables fine-grained, dynamic control over what can be signed and under what circumstances, without exposing master keys.
