The Bitcoin halving is scheduled to happen each 210,000 blocks, or roughly each 4 years. This explicit occasion will probably be executed mechanically by the community at precisely blockheight 840,000. Primarily based on the way in which Bitcoin’s creator Satoshi Nakamoto designed the system, bitcoin miners “find” the subsequent block to hash to the blockchain each 10 minutes, which means it must be simple to determine exactly when the subsequent halving ought to occur all the way down to the minute.
