Project revenue of 55 million LINK (equivalent to 5 years of mining) is pre-allocated into the Revenue smart contract. It will release it over 2000 days at a rate that decreases every 200 days.
The purpose of the revenue is to provide funds for re-investment into the Link ecosystem and to provide profit for the developer.
The block reward is the same as Ethereum. 5 LINK per block / 30k LINK per day.
