The way the key are generated, the owner of the wallet "knows" the used key by the indexes (M/x/y/z) of the keys so no need to store explicitly the points/addresses sharing non-extended public keys...a great secure way to use hd wallets ! | |

| Nov 30, 2014 at 20:08 | comment | added | idkwptc | Ok, I wanted to be sure I understood the principle. Sharing the extended public keys as advised in the specs looked "debatably safe" to me given the way the keys were generated. Thank you for your time ! :) | |
| Nov 30, 2014 at 20:05 | comment | added | Nick ODell | @idkwptc You could store the used points or the addresses. Either would work, for an audit. | |
| Nov 30, 2014 at 20:03 | comment | added | idkwptc | Well (I'm no expert at all so I may say something totally wong) each transaction related to the wallet use a public key (point on ec) so storing the used points should be enough to perform an audit without sharing the chaincodes, isn't it ? | |

you didn't need to calculate subkeys since you give all the public keys (N(M/*)) I don't understand. Could you clarify?
