# Inspiration\\nAt VeriDID, we are a startup specializing in custom verifiable credential management system development. We were inspired to use NEAR out of two concerns that we have. The first is that the existing blockchain used for AnonCreds verifiable credentials (Indy-Plenum) is slow, complicated, and is lacking maintainers and developers to keep up with the issues. Our second is that we want to be able to use our existing expertise in Javascript and Typescript to build smart contracts. We have Solidity experience, but we do not write contracts regularly and feel that staying in Javascript is a safer way to write secure contracts.\\n\\nThe use case came from an analysis of using Hyperledger Fabric for the mutual fund industry in Canada. The project did not go through as Fabric was deemed to complicated and expensive to run and it does not easily support business to consumer use cases.\\n\\n# What it does\\nThe system uses verifiable credentials to send fund reports to dealer and regulators. The dealers can then share a proof of the report to their customer and the regulators can do the same for their auditors. The verifiable credentials are generated using a project called credo-ts that provides us with AnonCreds standard verifiable credentials and DIDComm communication for handling the credential issuing protocols. For this project we have swapped out the Indy-Plenum blockchain for NEAR with NEAR smart contracts. Indy-Plenum does not support smart contracts and uses some wrapper code on the nodes to handle the access controls. This is not ideal.\\n\\nThe process for sending the reports takes 6 steps. Only steps 6 and 7 are required after sending the first report.\\n\\nInstantiate a credential agent\\nConnect the agent to another agent using an Out-Of-Band invitation\\nRegister a Decentralized Identifier for the report issuer using the NEAR Verifiable Data Registry (VDR) built with NEAR smart contracts.\\nRegister a credential schema for the report on the VDR\\nRegister a credential definition for the issuer\\\'s instance of the schema on the VDR\\nIssue a verifiable credential to the connected agent\\nThe credential recipient can share the report with another agent using a proof presentation\\n# How we built it\\nWe built the NEAR smart contracts based on your documentation and examples. We based the behaviour on how AnonCreds credentials expect to interact with a blockchain. We used the credo-ts project to handle the cryptography involved in generating the credentials and for the DIDComm communication protocols for peer-to-peer agent communication. We used Nest.js for our servers and Next.js for web interfaces.

VeriDID - Winning Project REDACTED Hackathon Waterloo City Node 3rd - $300USD

We would like to continue our work in using NEAR for a Verifiable Data Registry (VDR) for Hyperledger Indy projects.  A VDR is like a decentralized certificate authority.  The VDR is used by all organizations that want to issue verifiable credentials.
