Oracles

The veracity of the data fed into the six indicators will be essential to maintaining faith in the Arda Index. To this end, the Arda smart contract utilizes an oracle to ensure that we are removing the possibility that human error contaminates data inputted to the Arda Index.

An oracle is a data feed that sends information from the outside world to a blockchain. Blockchains are not able to natively pull data from off-chain sources. An oracle therefore allows for verifiable data off-chain to be brought on-chain that will provide a smart contract with the information required to execute pre-determined actions.

Initially, the oracle will pull from a repository for the data inputs and hosted on a soon-to-be launched public website. On our roadmap however is deep integration into the primary sources for current and future data inputs into the Arda Index.
