Nostr Web Client

Every nsec is an onchain wallet, when creating a nostr account you could create an xpub for the user, the user could keep it private in a nsec bunker, other user would send an event asking the npub for an address and the bunker would give it. Or the xpub can just be public if the user wants.

You could use Bitcoin Script.

// Main script

OP_OVER OP_HASH160 OP_EQUALVERIFY OP_DEPTH 0 OP_GREATERTHAN

OP_IF

OP_VERIFY

OP_ELSE

OP_RETURN

OP_ENDIF

//

OP_CAT OP_HASH256

OP_SWAP OP_CHECKSIG

OP_VERIFY

OP_BOOLAND

//

// Example condition: check if the event content contains a specific string

OP_SWAP OP_SUBSTR OP_NIP OP_EQUALVERIFY

//

// Example: Unlock the UTXO by sending the funds to a specific address

OP_DUP OP_HASH160 OP_EQUALVERIFY OP_CHECKSIG

With this script, do i need to know the transaction id to unlock the utxo?

Merging Nostr identities and Bitcoin Scripts can be 🤯

Let's hope to see more ideas like this:
