How Chainlink (LINK) Works 

Transaction Process  

When a smart contract needs external data, it sends a request processed by the Chainlink protocol via a Service Level Agreement (SLA) contract, which matches the request with suitable nodes and validates data.  

Chainlink node operators fetch and translate the data, delivering it back on-chain.  

Developers pay node operators in LINK tokens for these services, and fees are determined by the service demand. 

Wallets and Private Keys  

LINK is an ERC-20 token, making it compatible with various wallets like MetaMask, Trust Wallet, Coinbase Wallet, and Ledger Nano X for secure storage.  

As an ERC-20 token, LINK can be stored on any Ethereum private wallet.  

Hardware wallets like Ledger Nano S and X provide extra security through offline private key storage. 

Security Features  

Chainlink's decentralized architecture utilizes multiple independent oracle networks, preventing single points of failure during data and transaction verification.  

Staking mechanisms incentivize honest node operator behavior, as they risk losing their staked LINK tokens if they act maliciously.  

Chainlink oracles have secured over $12 trillion in on-chain transaction value. 

The Impact of Chainlink (LINK) 

Chainlink is instrumental in the tokenization of real-world assets (RWAs), like tokenized T-bills via OpenEden and tokenized equities via Backed Finance. This process brings real-world assets on-chain, enhancing liquidity, transparency, and accessibility.  

Banks and financial institutions, including Swift, DTCC, and ANZ Bank, are exploring Chainlink's capabilities for blockchain and tokenization use cases. Chainlink also supports DeFi innovations, utilizing Proof of Reserve (PoR) to verify assets backing RWA tokens, ensuring transparency for users.  

As of October 2023, K33 Research identified Chainlink's LINK as the "safest bet" for profiting from the RWA tokenization trend, given its role in connecting blockchains with the outside world. 

Chainlink's Cross-Chain Interoperability Protocol (CCIP) enhances global financial inclusion by connecting multiple blockchains.  

It enables seamless cross-border transactions and liquidity access for underserved regions.  

In November 2024, the Central Bank of Brazil piloted Chainlink's CCIP to automate cross-border commodity settlements.

Chainlink automates trade processes using dynamic NFTs for digitized documents, reducing inefficiencies in traditional supply chains.  

Vodafone's Digital Asset Broker (DAB) uses Chainlink to enable the exchange of trade documents across diverse platforms and blockchains.  

Key Aspects of Chainlink’s (LINK) Tokenomics 

Total and Circulating Supply  

LINK has a fixed total supply of 1 billion tokens, with approximately 600 million in circulation as of March 2025.  

The initial token distribution allocated 35% to the public through an ICO, 35% to node operators, and 30% for ongoing development.  

This model ensures that developers, node operators, and the company are invested in the network's success. 

Issuance Schedule 

All LINK tokens were pre-mined during the 2017 ICO, ensuring scarcity over time as no new tokens are minted post-launch.  

The initial distribution allocated 35% of the total supply to the public during the ICO and 35% to node operators as incentives. The remaining 30% was allocated to SmartContract, the parent company, for development purposes. 

Chainlink implements a revised token release schedule to establish a self-sustainable oracle economy.  

This schedule plans to release approximately 7% of the total LINK supply into circulation between Q2 2023 and Q1 2024, and a similar amount every twelve months thereafter. 

Consensus Protocol Process 

Chainlink employs a decentralized network of oracles that stake LINK tokens to validate data accuracy, ensuring agreement on the state of the blockchain.  

Oracles in a Chainlink network utilize Off-Chain Reporting (OCR) to aggregate their observations into a single report, which reduces gas fees and improves scalability.  

A designated leader coordinates this process.  

Chainlink oracles can use PBFT derivatives to achieve consensus, requiring over 2/3 of participants to be well-behaved, with deviations triggering epoch cancellations and new rounds. 

Utility and Adoption 

LINK serves multiple essential functions, including compensating node operators for their services and enabling staking for enhanced network security. It also facilitates the execution of smart contracts across prominent DeFi platforms such as Aave, Synthetix, and JustLend.
