In order to bring determinism to the oracle layer, Chainlink has developed a network of decentralized oracle networks (DONs), with each DON involving a combination of multiple security techniques needed to service a particular use case.
The Chainlink stack supports multiple open standards for designing and operating oracle services, which currently span four key verticals: 1) Data, 2) Interoperability, 3) Compliance, and 4) Privacy. Built upon these standards exists an ever-expanding collection of modular, purpose-built oracle services, which can be easily created and seamlessly composed using the Chainlink Runtime Environment (CRE). CRE is a developer platform and decentralized execution environment for running, managing, and composing oracle services into scalable end-to-end solutions, which run in a highly secure, reliable, and cryptographically verifiable manner.

Chainlink is the industry-standard oracle platform bringing the capital markets onchain and powering the majority of decentralized finance (DeFi). The Chainlink stack provides the essential data, interoperability, compliance, and privacy standards needed to power advanced blockchain use cases for institutional tokenized assets, lending, payments, stablecoins, and more. Since inventing decentralized oracle networks, Chainlink has enabled tens of trillions in transaction value and now secures the vast majority of DeFi. 
Many of the world’s largest financial services institutions have also adopted Chainlink’s standards and infrastructure, including Swift, Euroclear, Mastercard, Fidelity International, UBS, ANZ, and top protocols such as Aave, GMX, Lido, and many others. Chainlink leverages a novel fee model where offchain and onchain revenue from enterprise adoption is converted to LINK tokens and stored in a strategic Chainlink Reserve. Learn more at chain.link.

Chainlink is not a governance protocol. Chainlink is an open-sourced platform of standards developers leverage to build next-generation onchain applications. It is developed and maintained by Chainlink Labs and a broader community of contributors. While there is no onchain token-based governance like in some DeFi protocols, the direction of the protocol is guided by core developers, researchers, and ecosystem partners, with feedback from the community.

# Chainlink Maximum token supply Methodology

## 1. Overview

This metric represents the maximum possible supply of LINK tokens as defined by Chainlink's tokenomics. Unlike dynamic blockchain metrics, this is a fixed protocol parameter that represents the theoretical upper limit of LINK tokens that can exist. The metric answers the question: "What is the maximum number of LINK tokens that can ever be in circulation according to the protocol's design?" The calculation uses a static value approach since maximum token supply is determined by protocol specifications rather than real-time blockchain activity.

## 2. Data sources

This metric relies on protocol-defined parameters rather than dynamic blockchain data:
- **Protocol tokenomics specifications**: Official Chainlink documentation defining the maximum token supply
- **Token contract parameters**: Smart contract specifications that establish supply limits
- **Launch date records**: Official token launch date from protocol deployment history

## 3. Step-by-step calculation

### Component A: Maximum supply definition
- **Purpose**: Establishes the fixed maximum token supply value and launch date
- **Logic**: Sets the maximum supply to exactly 1,000,000,000 LINK tokens based on Chainlink's protocol specifications. The launch timestamp is set to September 16, 2017, marking when the LINK token became available. The calculation uses daily granularity to ensure the metric can be queried at a daily level.
- **Key fields**: `timestamp` (launch date), `timestamp_grain` (daily intervals), `token_supply_maximum` (1 billion tokens)

### Final aggregation
- **Combining components**: No aggregation of multiple components is needed since this is a single static value
- **Currency conversion**: Not applicable as this metric represents token quantity, not monetary value
- **Time aggregation**: The fill-forward strategy ensures the maximum supply value of 1,000,000,000 tokens is available for any date from September 16, 2017 onward
- **Final calculation**: The metric returns exactly 1,000,000,000 LINK tokens as the maximum supply for all dates from the launch date forward, representing the theoretical upper limit of tokens that can exist according to Chainlink's tokenomics design
