I’d like to learn more about how Daedalus’s mnemonics work.
The documentation says:
The full list of accepted mnemonic codes to secure a wallet is defined by the BIP-39 specifications. Note that picking up 12 random words from the list is not enough and leads to poor security. Make sure to carefully follow the steps described in the protocol when you generate words for a new wallet.
“full list of accepted mnemonic codes” – does this mean that all (12-word) combinations which are generated according to BIP39 can also be safely used with Daedalus?
If the relation to BIP39 is maintained, why not allow 15-, 18-, 21- and 24-word mnemonics? Mnemonics which encode only 128 bits of entropy (12-word ones) will become vulnerable once quantum computing becomes a viable threat. I’d hate to see a scenario where the first quantum attacks take place and people would have to be warned manually to generate new mnemonics and transfer funds as quickly as possible.
