Witnet

Witnet protocol enables smart contracts to realize their true potential by accessing a wide variety of valuable data sets and securely verifying and delivering this information with its strong cryptography economy guarantee. Witnet is designed specifically for 'autonomous' smart contracts -- contracts that require extremely high anti-jamming capabilities and leave no room for tampering. Witnet supports most DeFi primitives such as Price Feeds, Stable Coins, derivatives, etc. It also acts as a reliable source of randomness to create uniqueness in NFT (non-homogeneous token).
