Binance clogging the mempool?
1969 sats \ 50 comments \ @039957a0bd 14 Nov 2022 bitcoin freebie
Looks like the following wallet bc1qm34lsc65zpw79lxes69zkqmk6ee3ewf0j77s3h (should belong to Binance) is clogging up the mempool, next 100 blocks full of their UTXOs.
Sounds just like suspicious and bad timing as most of plebs are withdrawing their BTCs from the exchanges... what a shame!

Binance isn't clogging the mempool. They're outbidding everyone else.
Who knows why though. 😂

To incentivize alternative withdrawal methods :) aka faster and cheaper altcoins! But who knows :p
(AFAIK they don't support LN yet)

Perfect opportunity for full RBF transactions. My node is running full RBF. Peter Todd's node is running full RBF. If your tx is stuck and you need to increase the fee so it'll get through, connect to one of our nodes so a miner running full RBF might see it.

Indeed. I had to turn my full-rbf bounty reward down to normal fees (was ~$300) because double spends are certainly going to get mined.

...and a bunch of them got mined. The most expensive being: https://mempool.space/tx/397dcbe4e95ec40616e3dfc4ff8ffa158d2e72020b7d11fc2be29d934d69138c
One of the problems with trying to run a full-rbf bounty is it's too easy to double spend by accident. 😂

How does one tell this was a double spend from looking at the link you posted?

He's saying he increased the fee for that tx after it was already in the mempool and his tx with his donated sats got mined instead of the original.

Can you please ELI5 what this means in regards to full-rbf double spend?!
reply

Basically the simplest way to double spend an unconfirmed transaction is to just broadcast a new one with a higher fee. Nodes running full-rbf will replace the lower fee tx with the higher fee; nodes not running full-rbf will only do that if the transaction opts into replacement (about 30% of txs do).
When the mempool is full, lower fee txs get kicked out to make room for new ones with higher fees. This happens on all nodes, so it's particularly easy to double spend.
tl;dr: don't rely on unconfirmed transactions. Wait until at least one confirmation before treating them as a real payment.

Thanks I understand! This is how the police in a recent SN article tricked those ransomware people recently to send the decryption keys without it being confirmed. 'Double Spend by accident' that the poster mentioned above is not an issue with Bitcoin, but a human error when people do not wait for the confirmation to happen.

As long as I have a few confirmations, I am not at risk of this, correct?

Last time Binance did this was June crash. Maybe they know something big is about to hit.

[Edit: Oh, .. I see ... to cause a delay of a selloff.]
If I send a deposit transaction to an exchange and the fee wasn't high enough, and I didn't have RBF set, and I don't know about CPFP (or can't use it because it came from a custodial wallet), then my deposit transaction doesn't confirm and I won't be able to sell.

I think its to discourage withdraws rather than to delay a selloff

So this delay in withdrawals would prevent a bank run right? My thinking: if there are too many withdrawals and Binance had fractional reserves at some point they'd have to pause withdrawals, which would result in widespread panic

Mempool is currently full and purging. Someone more knowledgeable correct me, but we haven't seen this level of congestion since December 2017.

Is 300mb a fixed size of the mempool or just how the mempool tool did their UI?
reply
439 sats \ 0 replies \ @nerd2ninja 15 Nov 2022
The mempool is not a global state. It runs in the RAM of your computer when you run a full node. Most people have theirs set to the default of 300MBs, but I have mine set to 2000MBs, but I'm also running full RBF on my node. So if you send a tx at a higher rate, it'll either get replaced on computers with full RBF, or replaced on computers which are dropping low fee txs due to their mempool size limits.

It's the configured default mempool size is my understanding, so most relaying nodes are purging low fee txs to maintain that size.

sometimes it happens that you lost the transaction but after a while it get confirmed. so maybe the miners increased the size, but the nodes that broadcast the transaction did not.

As measured in vBytes. I don't remember the mempool purging, but maybe it was.
We also had a lot of congestion in April '21 getting up to 250 MvB, which most likely resulted in a lot of default mempool purging given segwit was widely adopted by then.

It will raise the price a lot, but not that much. Plenty of small transactions are pushing into the front of the line with higher fees. It will impact LN by raising the channel establishment/closing cost.

  • Paying sats to miners
  • Consolidating the UTXO set, which means less resource needed to keep its state in RAM
  • Incentivize using of L2 tech
that looks not that bad

Is this malicious from binance? curious
reply
10 sats \ 0 replies \ @iguano 16 Nov 2022
maybe not, in binance the people deposit to their account using a legacy address (this is the malicious part) but they (binance) tend to consolidate them all in one segwit address,
maybe they do this for compatibility, and they can improve the efficiency of the usage of the blockchain but is normal that a consolidation of a high-volume exchange will take a lot of space of the blockchain .
