- Accepted requests
- Average response time
- Penalty payments
The Chainlink Reputation Contract verifies an oracle provider’s authenticity and performance history, discarding any disreputable or unreliable nodes.
The Chainlink Aggregating Contract:
- Validates data from single and multiple sources
- Reconciles the validated data by averaging it into a single piece of data
- Ensures that the data provided to smart contracts is accurate and reliable
- Overcomes the limitations of blockchain smart contracts
- Provides a secure connection to real-world data
The Architecture of Chainlink: Securely Connecting Data Providers and Smart Contracts
Chainlink’s architecture, which includes Service Level Agreements (SLAs), off-chain data providers, and on-chain smart contracts, establishes a secure connection between data providers and smart contracts. Chainlink nodes employ the use of “Chainlink Core” software to translate requests from on-blockchain programming languages to off-blockchain programming languages that are compatible with real-world data sources.
External adapters in Chainlink facilitate interaction with third-party API endpoints, connecting blockchain technology to real-world applications. The OCR protocol enables nodes to compile their observations into a single report outside of the chain. A single node transmits a transaction containing the consolidated report to the chain. This transaction has to be endorsed by a quorum of nodes. This architecture allows secure access to real-world data for smart contracts, enhancing their capabilities and reliability.
Service Level Agreement (SLA) in Action
Service Level Agreements (SLAs) are instrumental in delineating the data needs and conditions for Chainlink users, aligning them with suitable oracles and data providers. An SLA outlines the data requirements and conditions for users, connecting them with suitable oracles and data providers. The SLA is enforced through a combination of sub-contracts, including a reputation contract, an order-matching contract, and an aggregating contract.
The order-matching contract logs the SLA parameters and collects bids from oracle providers, while the aggregating contract combines the responses from multiple oracles to generate a reliable and accurate result. This architecture ensures that the agreed-upon service levels are met, providing Chainlink users with accurate and reliable data.
The Chainlink Core Software
The Chainlink Core software facilitates the following:
- Translation of on-chain requests to off-chain language
- Routing of requests to external APIs
- Gathering and verifying data from off-chain sources
