This launch sets the stage for Hypersign's future advancements in identity management and integration across various digital platforms.

Introduction

In a significant stride towards advancing digital identity, Hypersign is proud to announce the release of Hypersign Identity Testnet Version 2.0, named Prajna, on January 19, 2024. This release marks a substantial enhancement over the preceding Jagrat testnet, emphasizing correctness, interoperability, and privacy improvements. The choice of "Prajna" for the testnet, signifying the "state of awakening" in Vedanta philosophy, reflects our journey through various stages of consciousness, paralleling the evolution of the Hypersign Identity Network.

The Journey from Jagrat to Prajna

Reflecting on Jagrat Testnet

The Jagrat testnet was our initial foray into exploring network behavior, governance processes, and functional capabilities. With the support of our validators, investors, and community, we undertook extensive testing phases, including functional, stress, and security testing. Challenges such as network halts were encountered and overcome, laying the groundwork for the next development phase.

Prajna Testnet: Enhancements and Innovations

1. Correctness

In our commitment to correctness, we meticulously reviewed and implemented W3C specifications related to self-sovereign identity, such as the decentralized identity core and the verifiable credential specifications. This approach ensures the compatibility of Hypersign-based DIDs with other DID projects.

2. Privacy

Privacy remains our utmost priority. We've implemented selective disclosure and zero-knowledge proofs in our verifiable credentials, enhancing privacy in various use cases. The introduction of BabyJubJubKey support and our custom crypto suite, BabyJubJubSignature2021 Suite, are pivotal in this endeavor.

3. Cryptographic Keys and Wallets

Our network now supports an array of cryptographic keys and signature algorithms, including Ed25519VerificationKey2020, EcdsaSecp256k1VerificationKey2019, and the new BabyJubJubKey2021, along with wallet integrations like Metamask and Keplr.

4. Interoperability and Smart Contract Deployment

Ensuring seamless interaction within the SSI infrastructure, we have integrated Interchain Blockchain Communication (IBC) for cross-blockchain DID and VC verification. This step enhances the flexibility and wider adoption of SSI.
Developers interested in creating ID DApps will have the opportunity to engage with native SSI modules, utilizing DID, VC, and similar tools to develop various ID products. However, we intend to avoid having the Hypersign ID network inundated with arbitrary contracts, as is common with other Layer 1 chains. While our primary vision encourages developers to create ID products on Hypersign, we place the decision-making power in the hands of our community. To facilitate this, we have implemented a governance-based approach for contract deployment. Developers wishing to deploy a contract must first undergo a review process by a pre-approved list of wallet addresses, initially comprising core developers. This list can be modified through changes in governance parameters. Only after receiving approval can a developer deploy their contract. This approach not only secures the network but also aids in reducing congestion and minimizing costs.

5. Governance and Fixed SSI Fee Structure

When it comes to governance and cost efficiency, customers need to assess the cost of a product before incorporating it into their existing systems. A notable challenge with web3 products is the fluctuation in transaction costs, which are often linked to the market value of the underlying token and the gas units needed for transaction execution. This volatility in transaction fees can be burdensome for businesses and individuals dependent on blockchain technology. For example, transaction costs can soar during elevated token prices, potentially making it unaffordable for users.
Therefore, it's vital to implement regulations for SSI-based transactions that guarantee fair and consistent fees. A consensus-based fee mechanism for each SSI transaction, establishing a fixed fee, can address this issue. By doing so, SSI transactions can have a distinct approach to transaction fee deduction. To this end, we have introduced seven fixed-fee governance parameters:
  • Register_did_fee fixed-fee parameter
  • Update_did_fee fixed-fee parameter
  • Deactivate_did_fee fixed-fee parameter
  • Register_credential_schema_fee fixed-fee parameter
  • Update_credential_schema_fee fixed-fee parameter
  • Register_credential_status_fee fixed-fee parameter
  • Update_credential_status_fee fixed-fee parameter
For example, imagine we initially set the price for a Create DID transaction in the Genesis block at 10,000 uHiD. If market conditions later warrant a reduction in affordability, we could lower the price to 8,000 uhid through governance proposals. This strategy ensures that SSI transaction costs remain fair and accessible for all users.

Unique Features and Developer Tools

Unique Wallet Association with DID for Reputation-Based Use Cases

Ensuring a one-to-one relationship between a blockchain ID and a single DID Document is crucial for reputation-based applications. This exclusivity is necessary to prevent the misuse of a single wallet for inflating the reputation scores of multiple DIDs, thus maintaining the integrity and reliability of the reputation system.

Support for BabyJubJub Key in Zero-Knowledge Infrastructure

We have incorporated the BabyJubJub (BJJ) Key into our zero-knowledge infrastructure, marking a significant advancement in privacy technology. The introduction of the BJJ Key paves the way for cutting-edge privacy features such as Selective Disclosure and Zero-Knowledge Proof, enhancing the security and confidentiality of our platform.

Integration of Metamask and Keplr Wallets

To facilitate a broader and more flexible use of DIDs and Verifiable Credentials (VCs), we have extended support to popular wallets like Metamask and Keplr. This integration is particularly beneficial for developers within the Ethereum and Cosmos ecosystems, allowing for the easy integration of DIDs and VCs into existing Decentralized Applications (DApps) without compromising user experience. This strategic move ensures seamless interoperability and user-friendly interactions across different blockchain platforms.

Software and Tools: For Developers and Builders

In addition to the Hypersign ID blockchain node, we are rolling out a suite of tools and software designed to enable developers to integrate self-sovereign identity into their current or new products effortlessly.
