Hi Chris,
I apologise if I did not make it clear enough, but the 24 seed words used
to make the quantum passphrase are separate, newly generated 24 seed words,
and not the same as those for the main wallet.
With both layers (seed words + quantum passphrase) the security provided is
Hi Chris,
Thank you for your thoughts.
Unfortunately, your analysis is incorrect.
This is a non-destructive adaptation of the BIP39 standard, and is
certainly not "rolling your own security".
The 'quantum' passphrase is relying on the well established security of the
existing BIP39 standard.
Thank you for your reply Tobias,
I don't think that the chicken-egg scenario is relevant, but please let me
explain why:
Wallet A = seed words (A) - add minimal funds as a canary/sacrificial wallet
Wallet B = seed words (B) - add minimal funds as a canary/sacrificial wallet
Wallet AB = seed
Hi Chris,
thanks for the clarification. It makes sense so far.
About the "chicken - egg" problem:
When you generate a BIP39 mnemonic "A" without password, you get a Seed
"As" from which you derive your private key.
Using the same mnemonic with a passphrase will give you a different seed
"As*"
Hi Tobias,
In answer to your questions...
"Isn't your suggestion already covered by BIP39 since there is not
restriction in how you choose your passphrase?"
- Correct, my idea is covered by BIP39, and therefore compatible with
BIP39... I see the 'quantum' passphrase as an optional 'soft fork'
Hello Chris,
Isn't your suggestion already covered by BIP39 since there is not
restriction in how you choose your passphrase?
It's up to any user to choose his password like you propose. I see your
proposal more like a way to choose my password rather than anything that
needs to be implemented
Hi,
I'd like to submit an idea for review, as a potential informational BIP
(Bitcoin Improvement Proposal), describing an optional method of producing
a BIP39 passphrase, using only BIP39 'mnemonic' seed words.
The idea specifically refers to a method of introducing two-factor
authentication, to
