How do I get a bitcoin attestation?

[mikedilger]

I tried "ots stamp --hash ID" and it gave me something. But the verify command at the bottom of the README says "no bitcoin attestations found".

Is my command correct? Am I even asking for one? I don't know.

Publish a nostr event that timestamps my NIP-41 (nostr-protocol/nips#829) replacement key event.
according to https://github.com/nostr-protocol/nips/blob/master/03.md

This is my whitelisting event:

{"id":"73a994a881ab41499ded5f0f880826e69a2ab673e56d8932929ffcabc2e3c8c5","pubkey":"ee11a5dff40c19a555f41fe42b48f00e618c91225622ae37b6c2bb67b76c4e49","created_at":1722977357,"kind":1776,"sig":"16a4b56bb243f2e3a398522f3395fa1d46cd746397c99ff4facf880cbb29b07cdf544781b4d38f3614145ee544ae6ee679612c90d17b83e8aa678ca73c696ea3","content":"","tags":[["p","df66c4594d14fc41305c118ff9779e1a65230a93d9205a6a2c118f6feab77592"],["alt","pubkey whitelisting event"]]}

Now I need an OTP attestation event like this

{"id":"5a969a26dbe80f2e703b1bdae1b5f81217a51982d996600217eb5ef6d3844e3e","pubkey":"ee11a5dff40c19a555f41fe42b48f00e618c91225622ae37b6c2bb67b76c4e49","created_at":1722978124,"kind":1040,"sig":"0d832bad88a07e90cb27e7b8e1e977fa24921307161c89e1c36a0618b7b919192c02a9251bbdc4c36ee0077561cd698b5d9f56d29c34c1dcc832ec21de894eef","content":"AE9wZW5UaW1lc3RhbXBzAABQcm9vZgC/ieLohOiSlAEIc6mUqIGrQUmd7V8PiAgm5poqtnPlbYkykp/8q8LjyMXwECxdLfBJJPeE1c661TemUFkI8SBsnGxbRHIfZ4xJGAvZSpHJM9QY4M45mp7n5gDW+v3zdAjxBGayjoTwCLwIVZ0LdSMSAIPf4w0u+QyOLi1odHRwczovL2FsaWNlLmJ0Yy5jYWxlbmRhci5vcGVudGltZXN0YW1wcy5vcmc=","tags":[["e","73a994a881ab41499ded5f0f880826e69a2ab673e56d8932929ffcabc2e3c8c5","wss://chorus.mikedilger.com:444/"],["alt","opentimestamps attestation"]]}

Except that this one appears to be wrong since it doesn't have any attestations in the OTP content. I created the content with

ots stamp --hash 73a994a881ab41499ded5f0f880826e69a2ab673e56d8932929ffcabc2e3c8c5

and then base64 encoded it.

What does ots info say when you pass in the file it gave you in ots stamp?

What happens generally is that you'll send your hash to a calendar server. The calendar server will wait until it has gotten more hashes from other people, then aggregate everything and publish a single Bitcoin transaction with a merkle root of all the hashes it had accumulated.

That process may take hours.

So you have to call ots upgrade with your file so this command will try to ask the calendar server if the transaction is already published and fill in the rest of the merkle path up to the block hash -- i.e. it will convert your "calendar attestation" to a "bitcoin attestation".

AHA ok I ran the upgrade, I have something now. Thanks.
