Quick take - Link token

All LINK tokens (1B total) were issued in September 2017 at inception, which is to say that there is a finite supply.

Timeline


  • 20 Jul 17. Steve Ellis (Co founder of Chainlink) proposes the addition of a new function to the ERC20 (Ethereum Request for Comments) token contracts. ERC677. Read the full ERC677 standard proposal HERE.

Utility

The LINK token is used to pay Chainlink node operators for their oracle services (on-chain data aggregation and submission & off-chain computation services). In addition, once Chainlink staking goes live, Chainlink node operators will be able to deposit a specific amount of LINK as collateral in order to be elegible to service specific requests. This was first outlined in the original whitepaper.


ICO and token allocation

ERC677

ERC stands for Ethereum Request for Comments. Ethereum Request for Comments is an official protocol for implementing improvements to the Ethereum network. ERC standards are created by the Ethereum community developers. The developers make a document describing methods and rules that they think would improve the Ethereum ecosystem. If the core developers and community agree with the proposal, it becomes a standard.

ERC20 Tokens The ERC-20 is a Token Standard that implements an API for tokens within Smart Contracts.

It provides functionalities like, to transfer tokens from one account to another, to get the current token balance of an account and also the total supply of the token available on the network.

ERC677 ERC677 is short for ERC: transferAndCall Token Standard #677. Steve Ellis (co founder of Chainlink) opened the ERC677 issue on Jul 20, 2017. ERC677 tokens inherit functionality from the ERC20 token standard, however ERC677 also allows token transfers to contain a data payload. Essentially it is an ERC20 token with the additional TransferAndCall functionality.

ERC677 tokens can be stored in any ERC20 compatible wallet.

At launch, 35% of LINK tokens were sold, establishing an initial circulating supply of 350M Another 30% (300M LINK tokens) were allocated to LINK's parent company (SmartContract.com)tokens were spent on hiring, operations and development.) The last 35% (350M tokens) are held in reserve to pay incentive rewards to network participants like node operators.
