The four-word codes

Restore codes are drawn from the BIP39 English word list, published with the Bitcoin Improvement Proposals and placed in the public domain. It was chosen because every word is short, unambiguous in speech, and distinguishable from every other by its first four letters — which is what lets QuizFu forgive a typo. Words unsuitable for a children's site were removed before use.
