Chaincerts is a cutting-edge platform that revolutionizes the way digital credentials are issued, verified, and showcased.
Chaincerts issues secure, non-transferable, and verifiable digital credentials on the Stellar network. Managed through Soroban smart contracts, serve as unique identity credentials that showcase an individual or entity's characteristics, features, traits, and accomplishments in a visually appealing format.
This repository hosts a collection of smart contracts, specifically developed for the purpose of creating, distributing, and revoking digital credentials using Decentralized Identifiers (DIDs) on the blockchain. The objective of this project is to provide a decentralized, secure, and tamper-proof solution for issuing and managing digital credentials, utilizing the power of Soroban smart contracts.
📖 As part of our commitment to transparency in the Chaincerts system, we encourage the use of a "build in the open" approach when developing these smart contracts. This approach allows anyone to easily review and examine the underlying code of the smart contracts, ensuring that they function as intended and do not contain any hidden vulnerabilities or malicious code. By using this approach, we can build trust in the system and promote greater confidence in the use of Chaincerts. Check the Open Source LICENSE for details.
The Issuance Contract defines the rules for issuing and managing digital credentials within the Chaincerts ecosystem. With this contract, issuing entities can set the revocability and expiration of credentials, define the eligible recipients, and restrict the distribution of credentials. Additionally, the Issuance Contract is responsible for executing the distribution action to different recipients, and it can revoke credentials making them invalid.
The DID Contract allows to manage a digital identity within the Chaincerts ecosystem. By following the guidelines set forth in the W3C DID Core specification, this contract empowers users to take control of their digital credentials, enabling self-revocation, customizable access capabilities, and streamlined credential issuance authorization.
The Deployer Contract is a simple wrapper that allows the Issuance and DID contracts to be deployed and initialized through one function, requiring the user to sign a single transaction instead of two.
The diagram bellow illustrates how the smart contracts manage the credential issuance, revocation, display, and verification processes.
In order to utilize the contracts, it is necessary to have Rust and Soroban installed. The installation process is outlined in the Soroban setup documentation, which can be accessed at Soroban setup.
