Understanding Bitcoin Halvings
A Bitcoin halving is a pre-programmed event in Bitcoin’s protocol that reduces the block reward miners earn by half. Created by Satoshi Nakamoto, halvings occur every 210,000 blocks (roughly four years) to:
- Control Bitcoin’s circulating supply.
- Simulate scarcity, akin to precious metals like gold.
