In Partnership with

QVI Support:

The vLEI Hackathon will support the further development of the GLEIF ecosystem. This includes Qualified vLEI Issuers (QVIs). They are essential, trusted service providers that issue and manage credential assurance, issuance and revocation. Participants may wish to collaborate with QVIs in the development of their proposals. The current Qualified vLEI Issuers are listed below.

Technical Information and Downloads

The vLEI is supported by a technology ecosystem and infrastructure based on the Key Event Receipt Infrastructure (KERI), Authentic Chained Data Containers (ACDC), and Composable Event Streaming Representation (CESR) suite of protocols. Infrastructure consists of signing infrastructure (wallets, witnesses, mailboxes, controller agents, and proxies), and verification infrastructure (watchers, verifier agents, observers). Some of this infrastructure is run by GLEIF and some is run by a network of Qualified vLEI Issuers and market partners. The GLEIF Testnet described below provides sample signing and verifier infrastructure components with the exception of a wallet. No specific wallet is provided below. There are open source, community wallets, proprietary wallets, and custom wallets that may be used with the below infrastructure. One such community wallet is the KERI Foundation’s wallet repository. Browser based wallets may be constructed with the signify-ts Typescript library.

Architecture Overview

The following PDF document downloads provide an overview of key GLEIF Testnet components that Hackathon participants may wish to use. The URLs for each hosted service may be found in each document. A general overview of the vLEI architecture can be found here: The GLEIF verifiable LEI (vLEI) Ecosystem training. The documents below describe each of the following components:

  • Witness Pool: A KERI Witness receives key event logs with controller signatures from KERI Agents. For authenticity, the witness adds witness signatures to the key events, then makes the key event logs available to Verifiers.
  • KERI Agent (KERIA) Server: The KERI Agent manages the key event logs of each Signify Client and publishes signed key event logs to witnesses.
  • Schema Server: this holds the schemas for Authentic Chained Data Containers (ACDC); this file server hosts the schema files in JSONSchema format for any used ACDC Credentials. The Schemas are JSON files that contain a schema describing the structure and format of an individual ACDC Credential
  • vLEI Reporting API: this is is used by Qualified vLEI Issuers (QVIs) to inform GLEIF of vLEI credentials that have been issued to entities and of updates for vLEI Credentials that have been revoked.
  • Webhook: The Webhook Call Receiver is an API service run by the hackathon participant that receives webhook calls from the Presentation Handler, a Verifier.
