☑️About BIP39

To understand BIP39, you need to understand BIP first.

What is BIP?

BIP is an acronym for "Bitcoin Improvement Proposal", which is "Bitcoin Improvement Proposal", proposed by Amir Taaki in BIP 0001 in 2011 and extended by Luke Dash Jr. in BIP 0002.

The so-called BIP is a standard that proposes to improve the Bitcoin protocol. It is used to introduce the Bitcoin design document with characteristic information. Design documentation for information provided by the coin community.

Types of BIPs

In the Bitcoin system, BIP can be roughly divided into three types: standard class, information class and process class.

All BIPs go through the same submission, review, and activation process, so the only difference between these three types of BIPs is their goals.

Standard class BIPs are submitted to change network protocols or other operating modes or functions that are sufficient to affect interoperability, including transaction verification and block size parameters.

Informational BIP mainly solves design problems and establishes general guidelines. Unlike standard BIPs, these BIPs usually propose entirely new network functions.

The process class BIP is roughly similar to the standard class, with the main difference: the process class BIP proposes process changes other than the Bitcoin protocol.

What are the current common BIPs

BIP 0011 (multi-signature output)

BIP32: A layered derivation scheme proposed to avoid the trouble of managing a bunch of private keys, which is the HD wallet shared by Shengchao before.

BIP44: It enhances the path definition specification for the layering of BIP32, while adding support for multiple currencies.

BIP39: Make torrent backup friendly by defining mnemonics.

BIP 0152 (Dense Block Relay)

In a short words , BIP39 is to make the private key more convenient and easy to store.
