About

Vulcan Link is an independent Chainlink node operator based in Philadelphia, PA. Our Oracle currently provides crypto price feeds and a couple money market interest rates for free. We are a prospective candidate looking to be added to the Chainlink Mainnet aggregator contracts.

Adversarial Security

Our Oracle and development efforts are operated with a philosophy of Adversarial Security and Decentralized Independence. These ideas are inspired from Sunny Agarwal's Byzantine Battalion. Please note Sunny is NOT related to Vulcan Link.

In the long run, we expect that well-funded authoritarian state actors will attempt to disrupt many decentralized platforms such as Bitcoin and Ethereum. If Chainlink Oracles become central to smart contract data, Oracle networks will also be part of the potential attack surface. It is therefore important for the Chainlink Oracle network to be decentralized and robustly tested by having independent node operators who present new ideas to the table. In the long run we believe this is in the best longterm interest of Web 3.0 development and LINK token investors.

We therefore conduct what we call "Adversarial Consensus Experiments" to challenge the strength of the Chainlink network such as token abstraction examples and incentivized Oracle Collusion contracts (we do not endorse any form of collusion between Oracles).

What we do

Vulcan Data Link connects your smart contracts with real-world off-chain data. Our decentralized oracle data feeds will enable your trustless smart contracts to rupture the confines of the blockchain and erupt into the real-world. Integrate your smart contracts with secure and reliable off-chain data such crypto prices, health metrics, and custom api requests.

Oracle Feeds

Services

We offer blockchain consulting services specializing in rapid integration of real-world data feeds into smart contracts. We can help you develop custom decentralized oracle  data feeds that aggregate outputs of independent node operators. Contact us for consulting on smart contracts, Chainlink, and development of custom adapters and feeds.

Our Company

Based in Paris, France, Vulcan Data Link strives to push the boundaries of integrating real-world off-chain data into smart contracts. We are the first node operator to provide official S&P500 data and COVID-19 data (updated daily from Johns Hopkins University dataset) on Ropsten testnet. Access our oracles and other official Chainlink feeds through our opensource Oracle Aggregator Dashboard.
