Version: IOTA


Since the IOTA network is permission-less, anybody is able to use it and interact with it. No central authority is required at any stage. So anybody is able to generate their own seed and then deterministically generate the respective private keys/addresses.

IOTA uses the Ed25519 signature scheme and addresses are usually represented by Bech32 (checksummed base32) format string of 64 characters.

A root of the Ed25519 signature scheme is basically a 32-byte (256-bit) uniformly randomly generated seed on which all private keys and corresponding addresses are generated. In the examples below, the seed is represented by a string of 64 characters using the [0-9a-f] alphabet (32 bytes encoded in hexadecimal).

Seed Mnemonics/Phrases

In modern wallet implementations such as the library and the firefly wallet, the seed is usually generated from a seed mnemonic (seed phrase), using BIP39 standard, to be better memorized/stored by humans. It is based on a randomly generated list of english words and later used to generate the seed. The seed is a root for all generated private keys and addresses.
