What about this block then? Its size is only slightly above 98Kb. Why is it not filled with all those transactions unconfirmed at that moment, huh?

Miners are getting hungry

I'm also curious about that (after much thinking).
maybe you should move this to the bitcoin discussion, it might get more replies there. not that this topic is about economics.

I meant economics actually. What all this may mean for Bitcoin ecosystem, short term and long term

that's 0.0001 for 2.7kb transaction. the right fee for that should be 0.00027.
your other transaction, the ones who got confirmed faster, may not have so many inputs.

by the way. who set the fee? you or the exchange? if it's the latter then that exchange is doing poorly with fee management.

I can't set the fee. But the question is still there, that is, why some blocks with tiny number of transactions (3 digits) don't include it

Number of transaction shouldn't be the main cause here. The blocks have a size limit, hard limit is 1mb, while soft limit is around 750kb. They can choose what limit they want as long as its between the two numbers. The blocks may have already been filled by larger transactions. Many miners has also set up a policy to accept specific transactions due to the spam eg. increasing minimum transaction fees.

you sure? it shows 4k+ from here. 10k~ yesterday, and 20k~ the day before yesterday.
just raise the fee a bit if you want your tx to be confirmed fast.

At the moment there are 19815 unconfirmed transactions. I'm not able to raise the fee, since I don't control it. I withdrew from an exchange. It is interesting that later withdrawals with the same fee (10,000 satoshi) went through, though...

I don't know what's going on

Checked on that time but there were not ~20,000 unconfirmed transaction.

Quote from: deisik on September 14, 2015, 06:38:47 AM

Besides, I see blocks with a very low number of transactions (and well below 1 MB in size). So could it be a concerted action by miners to get more fees, for example?

I think since the price of bitcoin has fallen down ~20$ then people don't trade.
So the number of transaction are small, and it's Monday (lot's of work in real life)

Here's the most recent snapshot. I don't know what else I can say

We checked at the same time, a bit confused
"7004 Unconfirmed Transactions Live updating list of new bitcoin transactions"
From this website? https://blockchain.info/unconfirmed-transactions , anyway the number is huge enough

It is not a problem with a TX fee. I've later had a few other transactions (with much smaller amounts) with the same fee (10k) which were confirmed without even one block missed...

Even from the same exchange

can you post the tx id? might help some people to point out what's the problem (if there is a problem).

I think there should be a mechanism to let you cancel the transaction and rebroadcast with a higher fee. At least you should get a market feedback of the ongoing fee rate depends on the network load

Well, it may be a bit of an exaggeration about the exponential part, but right now there are over 20,000 unconfirmed Bitcoin transactions. Yesterday this number was around 10,000. Personally, my own 1 BTC transaction got stuck and hasn't been confirmed for almost 20 hours already (this will be of particular interest to those who stubbornly continue to insist that Bitcoin transactions are fast and reliable)...

Your ideas, guys

Never had any problems today with any large transactions I made. Got 1 btc transaction just now and received 1 confirmation in just a matter of minutes. Looking forward for it to reach 3 confirmations. Funds came from trading with ecoin.eu

Now it seems the unconfirmed transactions were filtered out or got confirmed. Any way bitcoin network passed the stress test. But still need a solution for faster transactions.

Different sites/nodes have different policies. They can accept different transactions into their mempool depending on how their backend is structured. Sites with worst hardware or ram would tend to accept less transactions as too many of them may just crash their backend.

sorry. let me clarify my question. I see ~~4k-5k~~~ 6k~ unconfirmed tx in blockchain.info instead of 20k~ like OP.
should that happen?

I'm seeing 6k right now. The picture might just be outdated and blockchain.info is known to prune some transactions for whatever reasons. Plus the blocks seems to have high transaction count. It may have just help to reduce the spam.

I've given you the link. Exactly at blockchain.info

Update: now it reads 6K. Seems to be a glitch there

Well blocktrail.com has a different opinion.
149,000 transactions and counting. 83 mb mempool size

beat me to it.
also I see 4k~ unconfirmed transactions instead of 20k~. why is that?

The Status is of really a big concern when you are Trading . In trading all depends upon Confirmation of Transactions as though from the present scenario we can see that the bulk of Unconfirmed transaction is rising exponentially from last few days , and on up to it is stress test and spamming , for network to survive the size must be increased.

You'd better stop
