How often does Bitcoin’s mining difficulty adjust?
Bitcoin’s mining difficulty adjusts every 2,016 blocks, which is designed to occur approximately every two weeks. The protocol changes the target difficulty so that blocks continue to be produced at an average interval of about ten minutes, even when total mining power rises or falls.
What did the SegWit upgrade change?
Segregated Witness, or SegWit, separated transaction signature data from the traditional transaction structure. This reduced transaction malleability and increased effective block capacity. SegWit also enabled later improvements, including the Lightning Network, and introduced the foundation for native bech32 address formats.
What are bech32 Bitcoin addresses?
Bech32 is a human-readable Bitcoin address format introduced for native SegWit outputs through BIP 173. These addresses usually begin with “bc1” on Bitcoin’s main network. Compared with older Base58 formats, bech32 addresses provide lowercase-only encoding, built-in error detection, and more efficient SegWit representation.
