Supra is now Humanode’s official decentralized oracle provider

Humanode Core

01 Aug 2024 • 4 min read

If you’re a builder developing on the Humanode chain and need access to accurate off-chain and real-time price feeds for your dApps, or if you're a developer on another blockchain wanting to integrate Humanode's cryptobiometric technology for Sybil resistance without the hassle of deploying on Humanode—you're in luck.

We’re pleased to announce that Supra is now the official oracle provider for the Humanode chain and has launched oracle price feeds on the Humanode chain. This deployment means developers building on the Humanode chain will now have access to reliable price feeds from offchain sources and other chains. If you’re interested in reviewing the documentation directly, visit here. We will lay down the detailed use cases later in this article.

A blockchain oracle connects your application or smart contracts to real-world data. Without an oracle, blockchain services are limited to only what’s available on-chain, missing out the essential real-world data such as price feeds, real-world events, or even web APIs.

Imagine you have a robot that can only move around your house but can't look outside to see the weather. A blockchain oracle is like giving that robot a special window so it can see what's happening outside. This window helps the robot know if it's sunny, rainy, or windy. Without this window, the robot can only guess the weather based on what's inside the house. In the same way, a blockchain oracle gives your application or smart contract a way to get real-world information, like price feeds or events, that it can't see by itself.

Why launch Supra’s oracle on Humanode?

Reliable Price feeds: First, Supra’s price feeds allow dApps and smart contract builders on Humanode to access reliable off-chain data. Supra's oracles and dVRF support dApps across 85+ blockchains, offering accurate and secure data feeds with 600-900 ms data freshness.

Supra Distributed Oracle Agreement (DORA) fetches and authenticates price feeds from high-quality sources enhancing the interoperability of smart contracts to guarantee the future of financial markets by integrating real-world data into public and private chains.

DeFi dApps like lending and borrowing platforms need accurate data from external sources to function properly. This is where Supra’s decentralized oracles come in, providing the necessary data to ensure these applications run smoothly.

Development of Cross-chain Biomapper: Secondly, Humanode’s mission is simple: to make Web3 truly decentralized with one person = one vote = one node.While builders on Humanode can use its cryptobiometrics and Sybil-resistance features easily, developers on other chains face big challenges. They need a way to integrate these features without deploying them on Humanode. One of the use cases of oracles is the deployment of cross-chain Biomapper.

Let us explore in detail what this deployment means for devs building on Humanode and other chains.

What does this mean for developers building in the Humanode ecosystem?

As the official oracle provider for Humanode Supra enables decentralized lending, borrowing, and other web3 application development on the Humanode chain.

Supra provides real-time financial data. This is crucial for DeFi applications. Think of lending and borrowing platforms on Humanode. They can now access accurate asset prices and exchange rates. Loans and collateral valuations are based on up-to-date information. This reduces risks and builds trust among users.

How will the services and dApps on other blockchains benefit from this deployment?

The Humanode team plans to build the cross-chain Biomapper using Supra’s oracles.

This innovative tool will allow builders to utilize Humanode’s cryptobiometric technology without deploying on the Humanode chain. Users will be able to pay the fees from other blockchains and L2s without the need to hold HMND or buy it on CEXes. This feature will simplify user interactions with the Humanode cryptobiometrics, reducing friction and making it easier.

Here are some use cases that builders across multiple chains can leverage with the Cross-chain Biomapper:

1. Enhancing DeFi Lending and Borrowing:

In DeFi, ensuring each account represents a unique individual can prevent fraudulent activities and enhance trust. Supra's integration with Humanode enables the implementation of Cross-chain Biomapper which can be utilized by builders developing on other chains to ensure each user is a unique human. This is particularly beneficial for lending and borrowing platforms, where identity fraud risk is high. Developers can now build systems where loan approvals and collateral assessments are based on verified humans, enhancing security and trust.

2. One Person, One account in DAOs:

DAOs require a fair voting system to ensure decentralized governance. With Humanode’s private biometrics verification and Supra's data accuracy, developers can implement a "one person, one account" mechanism. This prevents the concentration of voting power and ensures that all votes are cast by unique individuals. This approach promotes fairer and more democratic decision-making processes within the app.

3. Cross-Chain Data and Interoperability:

Supra supports cross-chain oracles, allowing data to be read and written across different blockchains. This means developers on any EVM-compatible chain can leverage Humanode’s Sybil-resistance features. For instance, a dApp on Ethereum can verify user identities via Humanode’s biometrics, ensuring that interactions are genuine and unique across multiple blockchain environments.

Summing Up

The integration of Supra into the Humanode ecosystem provides developers with powerful tools to enhance their applications with Sybil-resistance using private biometric verification. By leveraging accurate data feeds, verifiable randomness, and cross-chain interoperability, developers can create more secure, trustworthy, and user-friendly dApps. This partnership not only advances the capabilities of the Humanode chain but also offers solutions for developers across various blockchain platforms.
