We focus on a clear, dependable Bitcoin halving schedule and countdown so you can quickly see the next halving’s ETA, blocks remaining, and block-reward changes. We’re grateful to the global open-source community and public block explorers for data and inspiration.
Btbjb is an independent information site maintained by a Bitcoiner. We specialize in the Bitcoin halving schedule and concise explainers. Our goal is to combine a clean design with reliable data to lower the learning curve so both newcomers and experienced users can grasp the key milestones at a glance.
We assume a long-run average block interval of about 10 minutes. Using public APIs for the latest block height, we compute the remaining blocks to the next halving height and derive an ETA. The actual date naturally shifts with hashrate and difficulty.
We query public height endpoints (e.g., mempool.space, blockstream.info, blockchain.info) with automatic fallback and refresh roughly every 60 seconds. Data is used solely to display height and ETA; we do not collect personal sensitive information.
