A Deep Dive on Chainlink

Chainlink serves as a bridge between the traditional world and the blockchain world, creating secure highways of information that connect these blockchain protocols to real-world data sources. In doing so, Chainlink helps to expand the functionality and reliability of blockchain smart contracts by providing them with real-world data and off-chain computations.

Overview and Purpose

Chainlink is an infrastructure project that solves a fundamental challenge in the blockchain space — the inability of smart contracts to access external data. By creating solutions that enable blockchains to communicate with each other and external "real-world" data sources, Chainlink plays a crucial role as a blockchain oracle in expanding their capabilities.

Network Architecture

At the heart of Chainlink's infrastructure are several key components that work together to enable secure data flow:

• Data Feeds: These rely on oracles to deliver real-time external data to blockchain networks, ranging from commodity prices to weather data and sporting event outcomes.
• CCIP (Cross-Chain Interoperability Protocol): This protocol enables different blockchains to communicate with each other, facilitating asset transfers and information sharing across multiple chains.
• Data Streams: Optimized for low-latency data delivery, these streams use a dual-oracle system – one set retrieves data off-chain while another verifies it onchain.
• Functions: These allow smart contracts to receive real-time data from Chainlink oracles without requiring developers to manage their own nodes.
• Automation: This service enables faster scaling of smart contract-based services through automated integration with the oracle network.
• VRF (Verifiable Random Function): This provides verifiably random values for applications requiring randomness, such as games.

Chainlink uses a unique consensus mechanism called Offchain Reporting for its operations.

LINK Token Fundamentals

The LINK token serves as the network's primary currency, used to pay network operators for providing external data to smart contracts. Additionally, token holders can stake their LINK (minimum 1,000 tokens) to contribute to network security and earn rewards.

Supply Characteristics

Chainlink has a maximum supply of 1 billion LINK tokens. The initial distribution was structured as follows:

• 35% (350,000,000 LINK) allocated to Node Operators & Ecosystem
• 32.3% (323,000,000 LINK) distributed through Private Token Sale
• 30% (300,000,000 LINK) retained by the Company
• 2.7% (27,000,000 LINK) sold in the Public Token Sale

The initial token sale occurred on September 17, 2017, at approximately $0.09 per LINK. The project expects to put about 70 million LINK into circulation annually, with full circulation projected by Q1 2030.

Project Development

Chainlink was launched on September 4, 2017, with its mainnet going live on May 30, 2019. The project originated in the Cayman Islands and was co-founded by Sergey Nazarov and Steve Ellis. Nazarov, who has been in the crypto space since 2011, serves as co-founder of Chainlink Labs and previously held positions at QED Capital and CryptaMail. Ellis, serving as CTO, co-authored the Chainlink whitepaper with Nazarov.

The project raised $32 million through its initial token sale, with $29 million coming from private investors at $0.09 per LINK and $3 million from the public at $0.11 per LINK.
