BIP84 is a proposal in the Bitcoin Improvement Proposals (BIPs) series, which is dedicated to the generation of Bitcoin addresses and wallet management. Specifically, BIP84 defines an account derivation scheme based on SegWit (Segregated Witness) and Bech32 address format.
Core content of BIP84
Address format: The addresses generated by BIP84 are in Bech32 format, which is a new address format introduced by the Bitcoin network to improve transaction efficiency and reduce transaction fees. Bech32 addresses start with `bc1`, and they can more efficiently encode and represent the input and output of Bitcoin transactions than traditional Base58Check format addresses.
Wallet structure: BIP84 proposes a derivation path for Hierarchical Deterministic Wallets (HD Wallets) to derive multiple private keys and addresses from a single root seed (usually a mnemonic or private key). This structure allows users to create multiple accounts and addresses without exposing or reusing any single private key.
SegWit support: BIP84 is specifically optimized for SegWit, a technology upgrade on the Bitcoin network that increases the capacity and transaction efficiency of the blockchain by separating certain data in the transaction (i.e., witness data) from the main body of the transaction and placing it in another part of the blockchain.
Application scenarios of BIP84
BIP84 was proposed mainly to meet the needs of the Bitcoin community for more efficient and secure wallet management. By using BIP84, Bitcoin wallets can provide a more user-friendly experience, such as:
Address reuse reduction: By generating a large number of unique addresses, BIP84 wallets can reduce the risk of address reuse, thereby improving user privacy protection.
Cost optimization: Due to the lower cost of SegWit transactions, BIP84 wallets can save transaction fees for users.
Compatibility and scalability: BIP84 wallets are compatible with the existing Bitcoin network and other BIP standards, while providing a good foundation for possible future expansion and upgrades.
Summary
BIP84 is an important part of the Bitcoin Improvement Proposal, which defines a derivation scheme for hierarchical deterministic wallets based on SegWit and Bech32 address format. By using BIP84, Bitcoin wallets can provide more efficient, secure, and user-friendly services, thereby promoting the continued development of the Bitcoin ecosystem.
