# Terminology
|
|
|
|
|
|
|
|
|
|
The key words "MUST", "MUST NOT", and "MAY" in this document are to be interpreted as described in RFC 2119.

# Abstract
|
|
|
|
|
|
|
|
|
|
This is HIP039 describing mnemonic seedphrases for Hush wallets.
|
|
|
|
|
|
|
|
|
|
# Motivation
|
|
|
|
|
|
|
|
|
|
Mobile lite wallets require a seedphrase which users can backup all addresses and funds in the wallet.
|
|
|
|
|
We are not interested to follow BIP39 exactly, but to use the latest improvements related to it's goal.
|
|
|
|
|
|
|
|
|
|
This project has some promising improvements to BIP39, notably embedding the "wallet birthday" directly
|
|
|
|
|
in the seed and versioning:

|
|
|
|
|
|
|
|
The improved KDF of scrypt will likely be used in HIP39.

# Specification
|
|
|
|
|
|
|
|
|
|
Currently HIP39 is targeted to be implemented in SilentDragonAndroid, with hushd support coming later
|
|
|
|
|
as things such as multi-language support is finalized.
