Problem statement :

Cardano metadata oracles are missing an operator-friendly node, making it hard for people to participate.

Describe your solution to the problem

We want to build an operator-friendly node software and would lower the barrier of entry for new oracle operators.

Relevant experience

We launched the first metadata oracle on Cardano, and we were the first community public oracle pool on Ergo blockchain.

Website/GitHub repository (not required) https://nut.link/
Detailed plan (not required) – Fill in here any additional details

Cardano metadata oracles (nut.link) are the first generation of oracles providing external data sources to the blockchain, that the developers can use.

At the moment, there is no operator-friendly node, making it hard for people to participate. By having a node that can be easily run by multiple operators, we would achieve both higher reliability of endpoints and higher degree of decentralisation.

We want to build an open-source, feature-rich, yet operator-friendly, node software. By doing so, we would lower the barrier of entry for new oracle operators and build the foundation of oracle pools.

External data provided by oracles is critical for developers and is a major dependency for dApps creations on Cardano.

You probably all know our proof of concept metadata oracles called https://nut.link/. At this time, we have five independent oracle operators that have provided more than 4 000 data points already!

The nut.link metadata oracles has been featured in:

First Cardano Oracles/What is an oracle?

 

 

## Potential

We would like to see more than 100 independent operators by end of this year, with datapoints consumed not only by wallets, but also by the dApps deployed within the Cardano ecosystem.

But we need to start with an oracle node.

 

## Deliverables

Within 2 months of receiving the funding, we will release the beta version, engaging with early adopters from the community. We will deliver the stable release within 4 months from the funding.

Deliverables of the metadata oracle node are broken down below:

  • Support for metadata oracle registration and data posting
  • Data source definitions templates that are easy to share within the operators’ community
  • Fetching and scraping of data with error handling and retries
  • Transaction construction, including dynamic fee estimation
  • Support for full local Cardano node (using `cardano-cli`) or remote API endpoint (lightweight metadata oracle client)
  • Prometheus style endpoint for monitoring and Grafana integration
  • Licensed under the open-source Apache License 2

We will maintain the project for at least a year and use project Catalyst in the future to extend it if there will be an interest from the community.

 

## Relevant experience

We have experience with oracles on UTXO blockchains. We launched the first metadata oracle on Cardano, and we were the first community public oracle pool on Ergo blockchain.
