Bech32

Definition ∞ Bech32 represents a specific address format utilized primarily for Bitcoin SegWit transactions. This format employs a checksum to detect errors and offers improved readability compared to earlier address types. Its design prioritizes efficiency and security, contributing to lower transaction fees and enhanced reliability for Bitcoin users. Bech32 addresses typically begin with “bc1”, signifying their compatibility with modern Bitcoin protocol upgrades.
Context ∞ The adoption of Bech32 addresses continues to expand as more wallets and services integrate SegWit support, making it a standard for Bitcoin transactions. While older address formats remain functional, the efficiency and error detection capabilities of Bech32 position it as the preferred choice for new implementations. Discussions often center on its role in optimizing block space and reducing transaction costs, particularly during periods of high network congestion. Its widespread acceptance is a key indicator of Bitcoin’s ongoing technical evolution and user experience improvements.
