DEPRECATED: Key standards for BLS12-381

These specifications have been deprecated in favour of EIPs 2333, 2334, 2335.

In order to further enhance interoperability, it is useful to define standards in addition to the BLS Signature Scheme, and BLS hash to curve standards.

These standards are specifically targeted at the blockchain industry, however wherever possible, a non-specific standard is used to ensure the proliferation of the standards.

This set of standards consists of the following documents:

Key derivation

• Mnemonic - A human-readable backup for secret keys which is converted into a seed
• Tree KDF - Building out a tree of keys from a single seed
• Tree Path - Allocating purposes to each key from the key tree

Key checksums

• Public key checksum - Checksums for addresses

Key storage

• Keystore - Encrypted files for storing and transferring private keys
