Blockchair utility endpoints: halvening countdown and per-chain data ranges.

How to use

  1. Bitcoin halvening — see the current block height, the next halvening block, blocks remaining, current/next miner reward, and the estimated date. Useful for tracking Bitcoin's supply schedule.
  2. Available ranges — shows the earliest and latest block/date Blockchair has indexed for each supported chain. Click a chain name to jump to its dashboard.
  3. Data refreshes automatically (halvening every minute, ranges every 5 minutes). Reload the page to force-fetch the latest values.
