@jack, what if the blockchain could optionally enforce a requirement that your transaction is signed with your Nostr key? Even with a vuln like ColdCard saw, funds couldn’t move without your nsec. We’d need a BIP but it seems wise to me. This feels like something
@Spiral could influence.
We’d have identity and money bound at the script level further improving security and control.
@Bitkey hw could also securely generate (or import) and hold your nsec file and link it to the phone app.
@Bitkey would also be an authorized signer in a BitKey wallet implementation so my transactions would either both be signed by me or one by me and one by you.
I think of this like DKIM or TXT DNS records. Or TLS requiring not just a key pair but signed by a trusted cert authority. Similar pattern only using Nostr.
