RPC error: -25: Min anchor quorum was not reached!

[dell1503]

Hi Guys,

Since this morning I run the script as well.
I always received the following output, where I start the Script as follow:
./main.py --config ./config.toml --repeat 30

I see the following Result in the Consol from the Script:

2021-03-02 16:39:17.583325 repeating the routine
================================================

checking competing anchors in BTC mempool

requesting anchor template from DeFi RPC
RPC error: -25: Min anchor quorum was not reached!

When I check defi-cli spv_listanchorauths I got a empty respond.
Is my assumption correct that the Script is working fine, but there is nothing to Anchor yet?
I reffering to https://github.com/DeFiCh/ain/wiki/Create-Bitcoin-Anchor where it staters:
"f it empty, then need to wait for 15 blocks to let your node to receive the anchor auths message"

As far as I understood the Script, this Error is not covered in the error handling of the Script?
Or is something wrong with my Setup?

RPC's are running both. Funds also available.

"RPC error: -25: Min anchor quorum was not reached!"

Don't ask me why, but this is normal behavior.
If someone else could explain why sometimes the anchor quorum does this in a bit more detail?

Please let your node run for half an hour to get the anchor auth information, and you can use the below API to check if you node received the anchor auth nodes.

defi-cli spv_listanchorauths

@AltCoiFish More information can be found in the link below.

Anchor teams creating the auths and confs can be found with getanchorteams.

defi-cli getanchorteams

  "auth": [

  ]

Auths used in anchor creation require signatures from 66% plus one members of the team to meet quorum.

defi-cli spv_listanchorauths

  {
    "blockHeight": 682245,
    "blockHash": "dbfadf572ca98e1c747de7d0e29e149052b63c27c45e440d868f267f1c07f644",

    ]
  }
]

The latest auth seen in spv_listanchorauths shows that this is not met for the team above. Further info is in the link I posted above.

Please let your node run for half an hour to get the anchor auth information, and you can use the below API to check if you node received the anchor auth nodes.

defi-cli spv_listanchorauths

Thank you for your replay. My defid Node is running more then 12h and still an emmpty respond:

~$ defi-cli spv_listanchorauths
[
]

I understood it like this, this should stay empty until the new Anchor team is created and they create the Anchor Data?
This is wrong?
I should always have a respond, at any time during the anchoring process?

Thanks for helping out here.

[AltCoiFish]

Thank you for your replay. My defid Node is running more then 12h and still an emmpty respond:

As a suggestion , after you did upgrade to version 1.5. did you start your dfid with rescan as this was needed at the time.
Check the upgrade procedure on https://github.com/DeFiCh/ain/releases/tag/v1.5.0

Not sure if its related here.

[ShengguangXiao]

Can you share your command line parameters for defid? And upload the log in ~/.defi/debug.log

[Bushstar]

What is the result of spv_syncstatus?

[dell1503]

I start from scratch, new Host and new BTC and DEFI Host,
Keep you updated.

So guys, I'm one step closer, I think.
I think I "solved" the problem of the empty list when do defi-cli spv_listanchorauths.
I Basically reset-up everything, the new host, and also BTC and DEFI Node. My BTC Node was quite old, and there was maybe a wrong config or so. I don't Know.
However, when I use in the config.toml:
Mode = "Fixed"
It seems to work, at least it creates a Transaction:

$ ./main.py --config ./config.toml
checking competing anchors in BTC mempool
ok

requesting anchor template from DeFi RPC
* DeFi block      : 86cc0d9cd8884821af2fddc3206cde609a8df9cbcfe0c250e49b32da5c6063b1
* potential reward: 55.00000000 DFI
ok

checking minimum profit conditions
ok

creation of anchor transaction
ok

sending anchor transaction
* BTC anchor transaction: 1c50f0c9ab8f19c0b065f1af6b8b5329c949862fdd0f73ad99fd045a6184d7ab
* DeFi block            : 86cc0d9cd8884821af2fddc3206cde609a8df9cbcfe0c250e49b32da5c6063b1
* potential reward      : 55.00000000 DFI
ok

Which is wired, that the Transaction didn't go through, yet, and the potential rewards is 55, where I see in the DEFI Block Explorer at that time 35 DFI.

When then Enabling in the config.toml:
Mode = "Estimation"

I recive directly an error:

$ ./main.py --config ./config.toml
Error: 'feerate'

Find attached my config.toml. (I removed the RPC Part) and the ~/.defi/debug.log
github.zip

[dell1503]

After restart the DeFi Node had had the same issue again that defi-cli spv_listanchorauths stays empty.
I notice that I had the pruned mode active in my config. I removed that and doing now a -reindex

[ShengguangXiao]

You node log has a lot of error like this, means the anchor syncing have problem, can you restart your node with -spv_resync option?

[dell1503]

I did. I stopped def-cli stop and re-launch the node with:
$ defid -spv -spv_resync -daemon

Checked the Status with

 $ defi-cli spv_syncstatus
{
  "connected": true,
  "current": 673163,
  "estimated": 673163
}

The debug.log look first (after sync) good, but then I spotted again some errors:
2021-03-04T20:17:32Z ERROR: ValidateAuth: anchor previousAnchor does not match top anchor

But when spv_listanchorauths looks better:

$ defi-cli spv_listanchorauths
[
  {
    "blockHeight": 685440,
    "blockHash": "bed023dbb8a2430c321fe75f6bea64422e6c4fb7c9e72551109b7cc59f412bb7",
    "creationHeight": 685755,
    "signers": 1,
    "signees": [
      "8UPz9hVnYKrHSz1FVBn3qz6hRrNjFrRYC8"
    ]
  },
  {
    "blockHeight": 685425,
    "blockHash": "2f7142d1425c8d4df31776c107b3967b2ddfa186f8c01ac680945ab1a7c67149",
    "creationHeight": 685740,
    "signers": 1,
    "signees": [
      "8UPz9hVnYKrHSz1FVBn3qz6hRrNjFrRYC8"
    ]
  }
]

Then I run the Script again after around 30min, after the -spv_resync was finished. Still the same Error:
RPC error: -25: Min anchor quorum was not reached!

I attached my defi.conf, debug.log and spv.log
github1.zip
Is there a special need for running spv?

[Bushstar]

There is a new version of DeFichain released soon that has a few updates for anchors. You could be running into issues related to those updates. After updating you will need to run -spv_resync again.

[dell1503]

After doing nothing on the Node, the Script went through. Nothing Changed

$ ./main.py --config ./config.toml

* potential reward      : 265.00000000 DFI
ok

However when checking the the Transaction, all look fine. How can I find the anchor team confirmation?

[Bushstar]

You can use spv_listanchorrewardconfirms to see the anchor confirms and spv_listanchorsunrewarded to see unrewarded anchors. Your anchor needs to be seen as active in spv_listanchors by the majority of the anchor confirm team to be confirmed for reward payment.

[dell1503]

Thank, I was able to verify the transaction.

Solution for Future reference:

First try to start the node with
-spv_resync
You can check status of the resync with defi-cli spv_syncstatus

After Sync is complete, wait until Anchor History is build, defi-cli spv_listanchorauths for me this took very long, like 8 hours.

If that doesn't help, rebuild the entire Blockchain.

Thank you all for the support!
