Very few wallets support anything other than English, = +which can lead to vendor lock-in and long term loss of funds if a rare = +non-English wallet disappears. + +However, because people can memorize things better in their native = +tongue, supporting multiple languages seems quite useful. + +I would prefer a new standard where words are mapped to integers rather = +than to a literal string. For each language a mapping from words to = +integers would be published. In addition to that, there would be a = +mapping from original language words to matching (in terms of integer = +value, not meaning) English words that people can print on an A4 paper. = +This would allow them to enter a mnemonic into e.g. a hardware wallet = +that only support English. Such lists are more likely to be around 100 = +years from now than some ancient piece of software. + +This would not work with the current BIP-39 (duress) password, but this = +feature could be replaced by appending words (with or without a checksum = +for that addition). + +A replacement for BIP-39 would be a good opportunity to produce a better = +English dictionary as Nic Johnson suggested a while ago: + =E2=80=A2 all words are 4-8 characters + =E2=80=A2 all 4-character prefixes are unique (very useful for = +hardware wallets) + =E2=80=A2 no two words have edit distance < 2 + +Wallets need to be able to distinguish between the old and new standard, = +so un-upgraded BIP 39 wallets should consider all new mnemonics invalid. = +At the same time, some new wallets may not wish to support BIP39. They = +shouldn't be burdened with storing the old word list. + +A solution is to sort the new word list such that reused words appear = +first. When generating a mnemonic, at least one word unique to the new = +list must be present. A wallet only needs to know the index of the last = +BIP39 overlapping word. They reject a proposed mnemonic if none of the = +elements use a word with a higher index. + +For my above point and some related ideas, see: = +https://github.com/satoshilabs/slips/issues/103 + +Sjors + +> Op 5 jan. 2018, om 14:58 heeft nullius via bitcoin-dev = +<bitcoin-dev@lists.linuxfoundation.org> het volgende geschreven: +>=20 +> I propose and request as an enhancement that the BIP 39 wordlist set = +should specify canonical native language strings to identify each = +wordlist, as well as short ASCII language codes.
