How do I share information about a transfer with Universe(s)? #907

For my test asset, I've now made two transfers, first in the amount of 5 and, then in the amount of 1. Both transfers have succeeded, in that I can run tapcli assets list on both of the recipient tapd instances, and the correct amount of both assets show up.

I have also somehow synced information about the FIRST transfer with at least one universe, but for the SECOND transfer, there seems to have been some synchronization failure, and it seems nobody else on on the network knows about the SECOND transfer.

On the machine that both 1) minted the asset and 2) runs assets.megalith-node.com, I can run tapcli assets transfers, and I see this encouraging list:

}

So, how could I find out why various universes don't know about this SECOND transfer?

Well, on this computer, I am hosting a universe, why don't I query the universe to see if it knows about the transfers?

So, I start here:

https://lightning.engineering/api-docs/api/taproot-assets/universe/asset-leaves#universerpcid

The AssetLeaves API:

AssetLeaves queries for the set of asset leaves (the values in the Universe MS-SMT tree) for a given asset_id or group_key. These represents either asset issuance events (they have a genesis witness) or asset transfers that took place on chain. The leaves contain a normal Taproot Asset proof, as well as details for the asset.

This sounds like what I want! So I run it

tapcli universe leaves --asset_id 5eb3e9332e8b0d12d4831e26dd9c6553c2467b9a6927e7006953b33987ddcf1e
{
    "leaves": []
}

Ok. This didn't work. So what if I try group_key instead of asset_id?

Great! So clearly my local universe knows something about this asset.

But -- my it seems my local universe does not know about the TRANSFERS ... When I run...

user@aw68:/src$ tapcli universe leaves --group_key 028ca92f8044d1eecdccd373ec358c4c282eefca0d9258793fea7086c45ad8537b --proof_type transfer 
{
    "leaves": []
}

.... Clearly: My local universe doesn't know about the transfers.

How could I tell it about the transfers?

My guess is that I might need to start by exporting a proof...

Export Proof
https://lightning.engineering/api-docs/api/taproot-assets/taproot-assets/export-proof

documentation:

Export a taproot asset proof that contains the full provenance of an
asset.

... and then import the proof to my local universe
Insert Proof
https://lightning.engineering/api-docs/api/taproot-assets/universe/insert-proof

documentation:

InsertProof attempts to insert a new issuance or transfer proof into the Universe tree specified by the UniverseKey. If valid, then the >proof is inserted into the database, with a new Universe root returned for the updated asset_id/group_key.

I tried various things, which were not successful, and eventually froze up after spending too much time staring at the InsertProof documentation:

--asset_id value    the asset ID of the universe to query for
--group_key value   the group key of the universe to query for
--outpoint value    the target outpoint on chain to locate a tap proof within
--script_key value  the script key (scoped to an assetID) to query a proof for
--proof_type value  the type of proof to query for, either 'issuance' or 'transfer' (default: "issuance")
--proof_file value

What does the asset ID of the universe to query for mean? In the context of an Insert of Proof, what does query for mean? My understanding is that asset_ids are unique, not scoped in any way by universes?

Also, I can understand where the group_key and asset_id would come from? But what about outpoint and script_key? Do I get that data from the tapcli assets transfers command?

I wonder if I am just misunderstanding and there is a better way to inform a local universe about a transfer?

Here is a zip file with the proof that appeared on the recipient of the 2nd (final) transfer.
aw57-1-megacoin.zip
My rough guess is that I need to somehow import this proof into a tapd node, then sync that node with a universe.
I tried

user@AW64:/src$ tapcli universe proofs insert --proof_file ./proofs/aw57-1-megacoin.assetproof
[tapcli] outpoint and script key must be set

So I think I need to figure out what outpoint and script key to set.

It seems that this proof includes the script_key, so I am confused about why the proofs insert command also asks for the script_key.

But, I do think this is the proof that I need to upload to one or more universes.

OK, this command seems promising:

It seems I did "insert" the proof, but still this node does not know about this transfer... When I run verifyownership using the proof file from the tapd node that retains the balance of this asset (94), it still fails.

I have now exported another proof, this one from the node which retained the balance of 94. Here is that decoded proof

What is a universe proof? Is that something different from an asset proof ? How can I obtain the universe proof corresponding to this transfer?

So now I want to go back to the node with 94 on it, and generate a proof:

I use this command...

tapcli --network mainnet proofs proveownership --asset_id 5eb3e9332e8b0d12d4831e26dd9c6553c2467b9a6927e7006953b33987ddcf1e --script_key $(tapcli --network mainnet assets list | jq -r --arg asset_id 5eb3e9332e8b0d12d4831e26dd9c6553c2467b9a6927e7006953b33987ddcf1e '.assets[] | select(.asset_genesis.asset_id == $asset_id) | .script_key')

and it generates this proof

Back on the computer I want to know about this proof. I run proofs verifyownership

This proof is still rejected with the same asset amount mismatch

 stderr='[tapcli] unable to verify asset ownership: rpc error: code = Unknown desc = error verifying proof: asset amount mismatch\n

So somehow I still need to figure out a way to propagate knowledge of this transfer to Universe(s). Any wild guesses on a strategy?

Even when I run it on the same node that generated the proof, that owns the 94 of this asset, when I run
tapcli proofs verifyownership --proof_file my_proof.foo
.. I still get the response
error verifying proof: asset amount mismatch

Another probably unrelated issue... This command https://lightning.engineering/api-docs/api/taproot-assets/asset-wallet/verify-asset-ownership

has in its docs use the dash character (-) to read from stdin instead ... I have tried various combinations of - after the command, followed by the proof in hex, but that has never worked. I can only get verifyownership to work by converting the hex to a binary file, and reading it with the --proof_file flag

verifyownership output failing seems like a new / undocumented bug.

To import a transfer proof, you should be able to do something like tapcli universe proofs insert --proof_type transfer ..., you'll need to also use the --asset_id, --group_key, and --outpoint flags I think to match the contents of the proof.

You may want to try the development CLI command importproof. I think you'd need to build the CLI from source to use that.

The error verifying proof: asset amount mismatch is a bug that I fixed recently on main. So it should be gone with the upcoming v0.4 release.
