The Bitcoin halving is scheduled to happen each 210,000 blocks, or roughly each 4 years. This explicit occasion can be executed routinely by the community at precisely blockheight 840,000. Based mostly on the best way Bitcoin’s creator Satoshi Nakamoto designed the system, bitcoin miners “discover” the subsequent block to hash to the blockchain each 10 minutes, which means it needs to be straightforward to determine exactly when the subsequent halving ought to occur right down to the minute.
