HD Wallets - Mnemonic Seed (BIP 39 standard)

From Entropy to Seed

1. Generate Entropy

2. Entropy to Mnemonic

3. Mnemonic to Seed

To create a mnemonic you first of all need to generate entropy, which is our source of randomness.

You can think of entropy is being a very large random number that nobody has ever generated before, or will ever generate in the future. It’s also best to think of this number as a series of bits (e.g. 10011010010001...), which is how computers store numbers.

(The entropy we generate must be a multiple of 32 bits, as that will allow us to split the entropy up in to even chunks and convert to words later on. Furthermore, the entropy should be between 128 and 256 bits, as that’s enough to make it impossible for two people to generate the same entropy)
