Flux is a cross-chain oracle aggregator that provides smart contracts with access to economically secure data feeds on anything. Every component of the protocol is designed to be maximally open-source, permissionless, and trustless, enabling individuals and communities to design and develop bespoke solutions for data provision and retrieval.

Flux is supported and developed by the Open Oracle Association, a Swiss Non-Profit entity with the sole purpose of supporting the ecosystem through the distribution of grants both in monetary means through USDC and the Flux Token (FLX).

Chainlink is blockchain middleware that allows smart contracts to access key off-chain resources like data feeds, various web APIs, and traditional bank account payments. By providing smart contracts secure access to these key resources, ChainLink allows them to mimic real world agreements that require external proof of performance and need to make payment in widely available payment methods e.g. bank payments.

The Chainlink Network is a decentralized network of ChainLink Nodes, which are all selling usage of specific data feeds, APIs and various off-chain payment capabilities directly to a smart contract. Any data, payments, e-signature, or other API provider, as well as individual developers, can easily join the network by connecting an API they're familiar with. Once the API they'd like to offer to smart contracts is connected to a ChainLink, they become a ChainLink Node Operator, responsible for keeping that API connected to the ChainLink Network and being compensated in LINK for their successful fulfillment of on-chain requests.

The LINK token is an EIP20 token with additional ERC667 functionality. The total supply of the token is 1,000,000,000, and each token is divisible up to 18 decimal places. To prevent accidental burns, the token does not allow transfers to the contract itself and to 0x0.

DIA (Decentralised Information Asset) is an open-source, financial information platform that utilises crypto economic incentives to source and validate data. Market actors can supply, share and use financial and digital asset data.

As a Swiss-based non-profit association, it is DIA’s mission to democratise financial data, similar to what Wikipedia has done in the broader information space with regard to central encyclopaedias. DIA data sources and methodologies are transparent and publicly accessible to everyone. DIA uses crypto-economic incentives for its stakeholders to validate data sources when be added and throughout their usage.

Pulse is an open-source app for prediction markets, by the community, for the community. Built on Flux Protocol.
