Build Link Contract For Free

Essentially, Chainlink is a middleware between on-chain and off-chain systems. By giving smart contracts access to off-chain resources, Chainlink lets them react to real-world events and execute agreements that would otherwise need external proof of performance.

Chainlink is a decentralized Oracle network that enables universally connected smart contracts. I'll try to explain this in just a second. It allows blockchains to securely interact with external data feeds and payment systems.

Instead of using Solidity or another specialized language for writing smart contracts, Solana uses Rust. Just last year, 90% of respondents in a software developer survey said they currently use Rust or have in the past.

In short, the process works the following way: you create a keeper compatible smart contract, register an upkeep job on the Chainlink Keepers web app, then Chainlink Keepers perform your upkeep jobs at the specified intervals without any further input from you.

Chainlink is a decentralized blockchain oracle network built on Ethereum. The network is intended to be used to facilitate the transfer of tamper-proof data from off-chain sources to on-chain smart contracts.

Step 1: Deploy an Oracle Contract to Kovan.Step 2: Build a New External Adapter.Step 3: Register Adapter URL in a New Chainlink Node.Step 4: Create a Job Specification for the external adapter.Step 5: Register the Chainlink node in the Oracle contract.Step 6: Create a requester contract to submit a request.Apr 29, 2019

A link contract is an approach to data control in a distributed data sharing network.In XDI, a link contract is a machine-readable XDI document that governs the sharing of other XDI data.
