I was thinking about various ways to keep a backup of a deterministic wallet seed, or an important private key (e.g. address used to donate to the AGS fund).
Offline or paper wallets risk loss through hardware failure, theft, fire etc.
Encrypted files could be backed up to various locations, but what if the encryption is broken somehow? Or you could suffer memory loss and forget how to decrypt the file!
My novel solution I will call the skin wallet
Tattoo your wallet seed or private key where the sun doesn't shine!
Just make sure you keep it secure! You'll have to do the tattoo yourself, keep it covered up, and avoid people accessing it by force!
It could be a good solution if you get amnesia.
It would also hopefully enable loved ones to inherit should you pass away.
Has this idea already been talked about?
