Unfortunately this keeps happening. BCHD happily reports that transaction is accepted, doesn't broadcast it further, responds as if transaction exists...

Happened today with 858f20eeffb834ee6ba88a09d6b4fcb0b0d379d5efcd0a0bddca65e6c6153513 (nowhere to be found), also quite a few daily reports from people who send money to someone and then later (after a restart) the money disappears. Happens daily.

How can we find out the root cause?

These transactions were affected (we have the hexes, so that means that BCHD accepted them):

858f20eeffb834ee6ba88a09d6b4fcb0b0d379d5efcd0a0bddca65e6c6153513
e6905b9ecfe88f6b654f70696a16534200ecde76253d929b19c67c08570dadc9

Unfortunately, it seems that BCHD has already restarted, so I can't find the information about them anymore.

We can we do? (My mailbox is now full of people (these transactions were to ~400 people) panicking that their money was stolen - there's a notification that they got the money, but the money is now gone... after BCHD restart, when mempool was reset)

The fee for tx was calculated by BITBOX this.BITBOX.BitcoinCash.getByteCount then multiplied by 1.01, then Math.floor.

Here's a similar transaction: https://blockchair.com/bitcoin-cash/transaction/ca7b6388346eed0e29b4e9c3907c813bb09b911c387426cbc1919b7da1d445c6

Size: 3,625 Fee: 0.00003662 BCH. So the failed transactions probably had a similar fee. So, it doesn't seem to be a fee issue.

It doesn't only happen with big transactions - sometimes transactions with just a few inputs-outputs fail. (By "fail" I mean that they are accepted by
BCHD, appear in mempool, can be spent, not broadcasted to the network or maybe the network doesn't accept the broadcast, disappear upon node restart)

Is there a way to enable verbose logging in BCHD maybe?

Even more failed/non-relayed transactions today:

Hundreds of people affected. Email blown away. What can we do?

When we first sent this transactions (via GRPC SubmitTransaction), we've got back this:

2f2f022d3579356a20ec985e4bdb9d30f8982b95cf2ca4e82771b71d454f6aca

So, the transaction was accepted.

If we go to https://explorer.bitcoin.com/bch/search/2f2f022d3579356a20ec985e4bdb9d30f8982b95cf2ca4e82771b71d454f6aca

We can see that the transaction did not reach the network:

If I try to SubmitTransaction again (though this time via Swagger over GRPC), I get:

{"code":3,"message":"tx rejected: already have transaction 2f2f022d3579356a20ec985e4bdb9d30f8982b95cf2ca4e82771b71d454f6aca"}

So, this transaction is in the mempool, but not broadcasted.

Finally, I went to https://rest.bitcoin.com/#/rawtransactions/sendRawTransactionSingle

I get:

{
  "error": "Missing inputs"
}

Ok, let's decode and see the inputs

Here's the 93db...:

If I submit it to BCHD I get:

tx rejected: already have transaction 93db5f6a539f4470fe1e2c3d015075f0dee2172e3bf86e72c68a9f9a92457733

If I submit it via rest.bitcoin - I get:

{
  "error": "txn-mempool-conflict (code 18)"
}

Now, I'm kind of stuck. I found this: https://updates.cryptoapis.io/?lng=en&page=5

Many customers got this error using our APIs or with their own node. It happens if you try to broadcast a second transaction and the first one is still not mined, which means it doesn't allow you to create more than one transaction from same address in the same block.

But this doesn't really help. A double spend? How?

The parent of this transaction is:

d6598c5b98545d57382fcf793978b461fbcb86fb70dc54abf02ca85209a98df4

and indeed, we can see this transacation on BCH network and we can see that 8d6da5c6fc593944a7c814c250fd49c03b05a756951002a37eae7887b6de6436 spends the last output.

The order of sending was:

This means that "get utxos" (GRPC call to the same node) got us d6598c5b98545d57382fcf793978b461fbcb86fb70dc54abf02ca85209a98df4 (which was long before that and was already spent by 8d6da5c6fc593944a7c814c250fd49c03b05a756951002a37eae7887b6de6436 - this is the first transaction we sent in this batch!)

How is this possible?

Ok, talking to @blockparty-sh it seems that in this particular situation a restart was a root cause:

R C:
one plausible explanation, however unlikely... is that we did 4 transactions, which went into mempool

node restarts

we try to get utxos, but it is still syncing mempool from outside

it gives us an old utxo

Jt:
well this wasnt really restarting at all before (other than rarely/manually for upgrades) and same issue was occurring

R C:
we spend it. bchd remembers and allows it, but then it doesn't allow external tx from bch network

Jt:
i can slow them down too

R C:
is there a way to find out was there a restart at the time?

Jt:

03:05:11 CEST; 41min ago
last restart

R C:
double spending transaction was sent at 2020-08-19T01:05:29.900951529Z yes ~40 minutes ago

Ok, i'll add it to the issue... I don't think it solves the original issue though

But it seems that we need to stop restarts

I think this is actually a problem of its own (getting UTXOs while node is syncing :( ), but it seems that it is unrelated to the original problem.

[zquestz]

Thanks for all the info, we will definitely be looking into this!

[zquestz]

Next time this happens, dump out the output from https://explore.cash, this uses the same node and can display the tx even if other nodes on the network don't see it!

[zquestz]

The fee for tx was calculated by BITBOX this.BITBOX.BitcoinCash.getByteCount then multiplied by 1.01, then Math.floor.

Here's a similar transaction: https://blockchair.com/bitcoin-cash/transaction/ca7b6388346eed0e29b4e9c3907c813bb09b911c387426cbc1919b7da1d445c6

Size: 3,625 Fee: 0.00003662 BCH. So the failed transactions probably had a similar fee. So, it doesn't seem to be a fee issue.

It doesn't only happen with big transactions - sometimes transactions with just a few inputs-outputs fail. (By "fail" I mean that they are accepted by
BCHD, appear in mempool, can be spent, not broadcasted to the network or maybe the network doesn't accept the broadcast, disappear upon node restart)

Is there a way to enable verbose logging in BCHD maybe?

Yes, there is a way to enable much more verbose logging. I am going to enable it tonight on my server. Just start bchd with -d debug

My guess is that upstream peers don't like the transaction for some reason. Have you tried broadcasting any of these transactions through bitcoin cash node or bitcoin abc? Want to help you figure this out! Also how quickly are you sending these transactions? Are they one right after another? Is there a delay between sends?

[readcash]

The problem is that these "bubbles" appear randomly. It's very hard to predict when and why. My hunch is that they might be due to low fees, especially if users ignore the maximum we recommend and set the amount manually (thereby creating a low fee transaction). But I thought #382 was supposed to solve that, but we've seen these bubbles after that too.

The problem with catching "sources" (hex representation) of user transactions is of course with the fact that they broadcast it themselves (via js) directly to the node, so we don't really have any way (currently) to catch and log that. I'll see, maybe I can add something.

It would be great if we could get more sample transactions that are stuck. That would ease our debugging immensely!

[zquestz]

I also have CRAZY logging enabled on my node now, so debugging these should be easier and I am logging every INV interaction between my node and its peers!

[readcash]

Thank you, Josh!

We'll have to wait for another report from users. I got some reports today, I replied to get some additional info, but still waiting for responses. I'll inform you when I have anything new. Thanks again!

Happened in last 24 hours. explore.cash can't find either.

Thanks!

I figured out that we have paid upvote TXIDs, so I can check them against rest.bitcoin.com, so I can easily find missing ones, at least here.

Some fresh transaction that happened on BCHD, but haven't been propagated:

I don't see any of these transactions in my logs even in debug mode.... very strange. Any chance we can start getting the full tx payload so we can analyze those? Also @cpacia if you have some time I would love help debugging this for our biggest user =)

[readcash]

I was hoping we could do without the full TX, since these actually are send browser-to-GRPC, so I have to create a completely new logging channel for this, but since we don't have any choice...

Me, too. I turned up the logging level on my node to debug and I assumed this would be trivial to track. Unfortunately I don't see ANY logs for these txs...

Still trying to monitor, but haven't got any "bubbly" transactions in the last 24h

GRPC (bchd.fountainhead.cash) replied with TXID, accepting it, but TX never appeared anywhere after this.

Ok, thanks for the detailed report. It is VERY strange that the node that replied with the TXID doesn't see it in its own mempool! That might give us a hint as to how this is broken. I want to see if there are any code paths that will return the TXID even if we decided not to accept it!

[zquestz]

@cpacia any ideas how that can happen? Are there cases we would return the txid but not add it to the mempool?

[readcash]

One more idea is that it was removed from the mempool later for some reason. But the only reason I can think if is double-spend, which is hard for me to imagine how it happened, since we get UTXOs before each send.

We don't have any code to generate the TXID, so it's 100% that we got it from GRPC

and bfa45 has a lot of successful spending transactions... :(

I would need to restart the node, since there's now about 50 transactions that spend descendants of this UTXO, which doesn't exist!

Hello,@read.cash ,my name is [cut]. I am a @read.cash regular user.
My @read.cash account name is [cut]. There is a problem in my account.And I also face many problems in my [cut] account.
Yesterday, 30 August 2020, I lost my 4.84$.
This 4.84$ I never got back.
Today,31 August 2020,when I sent the dollar money to another account, it showed me the success of the send money. But the dollar was not added to his account of the person to whom I sent the money and the dollar was not returned to my account.
Today I was sending 2.01$.
Today's send money Transaction: cda2b1ff9b78ce3fc3c4bd7f8e521be4aed09094

In two days I lost a total of 6.85$.
Now I am very shocked

You can close the issue if you will, read.cash no longer uses BCHD.

Not going to close it. Going to still try and figure out why you had these issues but other broadcast heavy apps have not... Just curious what are you using to track utxos now?
