[PRESS RELEASE – Bangalore, India, January 11th, 2024]
In a groundbreaking collaboration with Chainlink, Hypersign is at the forefront of revolutionizing decentralized finance by effectively incorporating Know Your Customer (KYC) processes into the blockchain. Using Chainlink functions, Hypersign introduces a transformative approach to On-Chain KYC Verification, seamlessly integrating Decentralized Identifiers (DID), Verifiable Credentials, and Zero-Knowledge Proofs. This strategic amalgamation tackles the inherent pseudonymity of blockchain transactions and establishes a robust framework ensuring user privacy and regulatory compliance. Moreover, the collaboration’s innovative use of Hypersign’s decentralized identifiers is pivotal in bridging the gap between traditional finance and decentralized finance (DeFi).
This collaboration facilitates the cross-chain verification of KYC data, offering a revolutionary solution that propels the financial industry toward a decentralized and interconnected future. Hypersign is set to launch its final testnet version, Prajna, on January 19th, and the mainnet goes live shortly after.
Problem Statement
In a Cross-chain Zero-Knowledge Proof KYC (ZK-KYC) verification system where the Issuer and Verifier operate on separate blockchains, the challenge is to ensure that when a user submits their proof to the Verifier Smart Contract, the contract can validate the legitimacy of the proof and confirm its origin and issuer’s attestation from another blockchain, essentially verifying that the user possesses valid credentials issued by the authorized entity.
Example Scenario
Consider a user with credentials on one of the Cosmos AppChain (Hypersign ID chain) attempting to verify their identity on a separate Ethereum Virtual Machine (EVM) chain. The challenge lies in efficiently confirming the validity of the user’s Zero-Knowledge Proof (ZKP) and ensuring the associated credential is authorized by the issuer on the Cosmos AppChain.
Solution- Utilizing Chainlink Functions and Hypersign DID
The solution employs Chainlink Functions to facilitate interoperability between blockchains, allowing any Ethereum Virtual Machine (EVM) chain to validate the issuer’s attestation on the Cosmos AppChain (Hypersign ID chain). This process entails users submitting Verifiable Presentations (VPs) and conducting validation through a combination of Chainlink Functions and the Hypersign Decentralized Identifier (DID) network. A critical component is the Groth16Verifier smart contract, built on the Groth16 zero-knowledge proof system, which plays a pivotal role in verifying proofs on the EVM chain, ensuring the integrity of provided information aligns with the expected parameters. Users submit their Zero-Knowledge Proofs as VPs to the Business Smart Contract on the EVM chain, and this Business Contract utilizes Chainlink Functions to cross-verify the issuer’s attestation from the Cosmos AppChain, confirming the ZK-Proof’s association with a valid credential issued by the authorized issuer. Following successful Chainlink-based verification, the Business Contract proceeds to authenticate the ZK-Proof by interacting with the Verifier Smart Contract on the EVM Chain.

Road Ahead
Hypersign is set to launch its final testnet version, Prajna, on January 19th, showcasing significant advancements in its technology with the participation of key figures from the SSI and Cosmos ecosystem. Introduction of the “X25519KeyAgreementKey2020” Verification Method and the innovative BBS+ Signature Scheme for enhanced digital security. Additionally, the integration of Baby JubJub Key pairs and advancements in DID Document canonization reflect Hypersign’s commitment to secure, private transactions and standardized decentralized identities. The reconfiguration of the SSI SDK and improvements in the Credential System further highlight its focus on developer accessibility and efficient credential management.
Hypersign ecosystem is powered by its native token, $HiD, which will be used for governance once the AppChain goes mainnet.
