The first halving event in the Ravencoin blockchain took place on 11 January 2022 at block 2,100,000. Following this event, block rewards for miners were reduced by 50%, falling from 5,000 RVN to 2,500 RVN. The next halving event will occur after another 2,100,000 blocks are created, which would take approximately 1,458.3333 days from the first event. In terms of years, this would be another 3.99 years from the first halving event. However, this calculation assumes that block time remains 1 minute, which cannot be guaranteed. Block time is subject to change based on differences in mining power, which could impact this timeline shared by Ravencoin developers.
