TrustLink Labs is building foundational infrastructure for the Internet of Value through TSN, a hybrid settlement network designed to make value transfer interoperable, identity-aware, and privacy-preserving across applications and blockchain networks. TSN combines off-chain coordination and verification with on-chain authorization and asset settlement. Cross-network interoperability is an architectural goal; individual routes must be verified before they are described as live. The network combines protocol layers with application SDKs so a payment can be addressed through a portable identity, authorized by a wallet, checked against private state, and settled under asset-specific rules. TSN names the full infrastructure. TSNP is the on-chain Transfer Settlement Network Protocol. TIP manages transfer identity, including the 10-digit TIN. GPRU guards the integrity and privacy of the user’s private state presented to TCAP. TCAP governs the accepted assets, reserves, and settlement transition. DIP describes the deposit-ingress protocol for external value. Circle’s CCTP is a separate protocol used only where an integration supports it. The design goal is to keep identity, private-state verification, and asset governance in distinct roles. GPRU’s proof is intended to show that a hidden state is current and that a proposed change follows from it; TCAP remains the authority over funds and applies authorized changes atomically. The hidden-head proof path and confidential debit/exit are not established as end-to-end capabilities. For current implementation and deployment status, see Current Protocol Capabilities. The detailed engineering record is maintained in the repository documentation.
