I am not sure that this discussion is really off topic for this list, this is a real issue, would everybody even here say that they feel very comfortable with their keys? That if something happen to them there is no pb for the family or trusted parties to retrieve the keys? That this process is secured in case the trusted parties are finally untrusted? etc
I don't think so, if experts are not comfortable then how can we expect non experts people to manage this? (except going to a wallet sw asking them all the info, even online, crazy but they just don't know) Comments below Le 30/09/2017 à 06:49, Jonas Schnelli via bitcoin-dev a écrit : > And I would also extend those concerns to BIP39 plaintext paper backups.

This is the intent of https://github.com/Ayms/bitcoin-wallets and https://github.com/Ayms/zcash-wallets But even myself can get confused, where did I put the backup seed? But remember you did not backup the seed but the first derivation step and you mixed it secretely, so nobody can reconstitute it except you, well... what did I do exactly? What version is my real wallet? What is the encryption key? How did I do last time to add the key in qt? etc > They should never leave the device over the channel used for the signing > I/O.
