Plutus is Cardano's smart contracts platform. We develop web3 solutions for Cardano in Haskell. Cardano is based on EUTXO, as is Bitcoin.

Cardano is built on Haskell and based on the dedicated Ouroboros consensus algorithm. The blockchain's cryptocurrency is ADA.

Chainlink Oracles, data feeds, VRF and automation - these are leading features of Chainlink available for smart contracts and web3

Data feeds are data "produced" by oracles, published on the blockchain, available to be read for free by smart contracts.

The oracle's business model is to execute off-chain (off-blockchain) queries and return them to the contract in exchange for a fee, which the contract pays by asking oracles for off-chain data.

External data to the smart contract (from outside the blockchain) can be provided only, as parameters (arguments) of its call. Oracles are software running outside the blockchain, which listens for "requests" by smart contracts for external data,…
