When #halving? Current block 838,971
Number of blocks remaining: 840,000 - 838,971 = 1,029 blocks
Time until block 840,000: 1,029 blocks * 10 minutes per block = 10,290 minutes
Bitcoin halving is like a scheduled event that reduces the number of new bitcoins miners can earn. It happens approximately every 210,000 blocks mined. The first halving occurred after 210,000 blocks, the second after 420,000 blocks, and so on.
Currently, we're expecting the fourth halving to occur around 840,000 blocks. When the halving happens, the number of bitcoins rewarded to miners for each block they mine gets cut in half. This helps control the supply of bitcoins over time, making them more valuable and ensuring the system remains secure.
