The Data Connector is able to come to consensus on information from external blockchains and the internet, so that it can be used securely and trustlessly by smart contracts on Flare.
Why
The Data Connector allows applications to be built on Flare that can use data from external blockchains and the internet securely. It can power a wide range of interoperability solutions which in turn will enable developers to build applications that are multi-chain or cross-chain. Developers will be able to access the value, liquidity and information of multiple ecosystems through a single deployment.
How
The Data Connector uses a set of independent attestation providers which fetch the required information from other blockchains and deliver it to the Flare network. The Data Connector smart contract then checks if there is consensus among the received answers, making the results available to the network if so.
The Data Connector operates in one of two modes:
- Read the state of other blockchains and, for instance, prove whether a deposit has or has not been made by a given blockheight.
- Provide data proofs from open internet APIs. For example it could confirm whether a specific tweet was sent, a specific sporting result occurred or if a bank transaction was completed.
The Data Connector allows information from other chains and
the internet to be securely and trustlessly used on Flare.
