TRISA Protocol and API

This section of the documentation describes the TRISA Protocol and API.

Navigating the Open Source TRISA Code

The trisa repository contains a gRPC implementation of the TRISA protocol as described by the white paper, which leverages protocol buffers and Golang.

The proto folder contains the core RPC definitions, including:

• the interVASP Messaging Standard (IVMS) message definitions, which serve as the basis for how two VASP peers should mutually describe entities involved in cryptographic transfers, including names, locations, and government identifiers. This is the spec that will allow originators to identify themselves to beneficiaries and to request information from those beneficiaries to meet the legal requirements of their regulators.
• the TRISA Network’s service definitions, essentially how the different parts of the API work — from the exchange of keys (to ensure both peers have the requisite details to exchange information) to the transfer of “secure envelopes” (cryptographically sealed protocol buffer messages that can only be decrypted by the intended recipient). The trisa subfolder also contains generic message types for transactions that are intended to provide maximum flexibility for a wide range of TRISA use cases.

The pkg folder contains the reference implementation code, including compiled code generated from the protocol buffer definitions in the proto folder¹.

• The iso3166 folder contains language codes.
• The ivms101 folder extends the generated protobuf code with JSON loading utilities, validation helpers, short constants, etc.
• The trisa folder contains structs and methods for a range of TRISA-related tasks, such as performing cryptography and making mTLS connections.

The lib folder is intended to showcase utility code similar to that in the pkg folder, but for languages other than Go. If you work in a language other than go, this would be a great place to start your contribution!

Another integral part of the TRISA protocol is the Global Directory Service, which serves as a look-up tool for TRISA members to identify peers with which they wish to exchange information.
