List of crypto coins, oracles and projects that provide data to blockchain smart contracts. Watch some fun videos



Chainlink (coin "$LINK") is an Ethereum token that powers the Chainlink decentralized oracle network. This network allows smart contracts on Ethereum to securely connect to external data sources, APIs, and payment systems. (Ref


File Coin

Filecoin (coin "$FIL" ) is a cryptocurrency that powers the Filecoin network, a decentralized peer-to-peer file storage network that aims to let anyone store, retrieve, and host digital information. FIL tokens are used as payment for these services and as an economic incentive to ensure files are stored reliably over time.(Ref

The Graph

The Graph (coin "$GRT") is an Ethereum token that powers The Graph, a decentralized protocol for indexing and querying data from blockchains. Just as Google indexes the web, The Graph indexes blockchain data from networks like Ethereum and Filecoin. This data is grouped into open APIs called subgraphs that anyone can query. (Ref



Chromia(coin "$CHR" )Chromia is well positioned for the fast growing crypto blockchain by being the relational blockchain platform. Chromia leverages your database SQL knowledge to the decentralized Apps with its own coin “CHR.”



Polygon(coin "$MATIC" ) Ethereum's Internet of Blockchains! Polygon is a protocol and a framework for building and connecting Ethereum-compatible blockchain networks that are faster & less expensive.
