BREAKING: #China dumps $4 billion worth of U.S. treasuries in 7 months.

Here is what happens:

1. Generate the Seed Phrase:

• The wallet software generates a random 128-bit number (entropy).

• This entropy is passed through a hash function (SHA-256) to produce a checksum.

• The original entropy and a portion of the checksum are combined to create a 132-bit number.

• This 132-bit number is split into 12 groups of 11 bits each.

• Each group of 11 bits is mapped to a word from the BIP-39 word list, resulting in a 12-word seed phrase.

2. Convert Seed Phrase to Seed:

• The 12-word seed phrase is converted into a binary seed using a key stretching function called PBKDF2 (Password-Based Key Derivation Function 2).

• The 12-word seed phrase is used as the input password for PBKDF2, and “mnemonic” is used as the salt.

• The PBKDF2 function runs 2048 iterations of HMAC-SHA512, producing a 512-bit seed.

3. Add the Passphrase:

• The passphrase (if provided) is concatenated with the 12-word seed phrase to form a new “mnemonic + passphrase” string.

• This combined string is again fed into the PBKDF2 function, with the same salt (“mnemonic”).

• PBKDF2 runs another 2048 iterations of HMAC-SHA512, generating a new 512-bit seed.

4. Derive the Master Key:

• The 512-bit seed is used as the input to HMAC-SHA512, generating a master private key and a master chain code.

• These are used to create a hierarchical deterministic (HD) wallet structure, according to BIP-32.

5. Generate Child Keys:

• From the master private key and master chain code, child private keys and chain codes are derived for different account levels (e.g., account 0, account 1).

• Each private key corresponds to a Bitcoin address.

By adding a passphrase, you’re effectively creating an entirely different seed, which results in a completely different set of keys and addresses. This additional layer of security is sometimes referred to as a “13th word” or a “seed extension.”

In short;

1. Generate entropy (random 128-bit number).

2. Convert entropy to a mnemonic seed phrase using the BIP-39 standard.

3. Use PBKDF2 with the mnemonic seed phrase and passphrase to create a 512-bit seed.

4. Derive master private key and chain code using HMAC-SHA512.

5. Generate child keys and addresses using BIP-32. 🎯🙌🫡

You don’t need to reassure people here that you keep your word.

We assume you will.

You’re here.

But if you don’t? Better spin up a new Npub.

If you want a nip05 identifier for your nostr profile you can use

fluterbus@nostrich.cc in your profile!

we respond like the hydra

Totally agree!

Much appreciated. Just received. Thanks and let’s keep connected.

As per my perspectives, If quantum computers become a threat to Bitcoin, the community might do a "fork" to upgrade to stronger cryptography, making Bitcoin's security even better. They'd make this move based on how quickly quantum tech is advancing, not just after attacks happen. Also, a quantum hacker might test their skills on smaller targets first, keeping their strongest attacks hidden until needed. This plan would help Bitcoin stay safe by improving its security ahead of time. Does it make sense ?
