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. --- # Agent Instructions This documentation is published with GitBook.
