Topic: Is it just me; or... (Read 1060 times)

It seems just you, I've made several transactions the past few days, and it didn't take even a fraction of the time you stated to be conformed.

This is somewhat misleading, so I'll just clarify. After those blocks, if there were longer block times, it was merely because of chance. The last difficulty change (that is used to balance the system) was on 5th of June and the next one will be in a few days. Between these times, block times are not balanced in any way, they are randomly found every ten minutes or so, probably a little less than that now as the hash rate is usually growing all the time while the difficulty is adjusted only every 2016 block or approximately two weeks.

I posted these stats in another thread, but as I have not seen them posted on these forums before, I repost them in this thread since most have probably not seen my post in the mining section:

The probability of finding the next block in

less than 1 minute: 9.5 %
less than 5 minutes: 39.3 %
less than 10 minutes: 63.2 %
less than 30 minutes: 95.0 %

As you are reading this, the probability that you have to wait more than one hour from this moment until the next block is found is about 0.25 %, small but significant and without checking the blockchain I am quite sure longer block times have been seen many many times before. It would be expected to see a 90 minute block time about once per year. (Well, of course this kind of prediction is not reliable, because in a year there will probably be things are not accounted for in the theoretical model, such as the hash rate drops due to something unexpected)

My calculations were based on the assumption of average ten minute block time, which happens when difficulty is "correct" for the current hash rate, and that finding Bitcoin blocks is a very good example of something that is well modeled by a Poisson process. At the time of this post the average block time is probably somewhat less than ten minutes, so the first four probabities should be a bit bigger and the probability for the next block to be found after an hour or more should be even less than 0.25 %.

You may need to wait for confirmations. It is not just you who see this unconfirmed, there are tons of people who are in the same situation.

Sometimes the time between blocks found is longer than the average time, so the btc transaction will go slower.
If you have this all the time: 1: you are unlucky.
                                             2: something is wrong with ur pc or connection.

On average there will be one block found every 10 minutes. The time between each found block can very greatly from less then one second between blocks to close to two hours between blocks (it usually will not get to be more time then this but is can).

It can sometimes take a couple (or more, sometimes up to 6 blocks depending on the TX policy of the pools that find the blocks) of blocks to get your first confirmation even if you include a fee in your TX.

As long as your TX is showing up on blockchain.info's node (their website) your TX should eventually confirm.

Sometimes blockchain is really slow. Just wait

first confirmation takes seconds... complete transaction might take 30 minutes or so.

you may need to wait a minimum of 3 confirmation

Some time blockchain works slow yesterday I have to wait for 40 minutes then block came and I have confirmation but today its working very good and giving confirmations very quickly 

If you look at the block history on the blockchain.info homepage you can see the blocks have been a bit erratic the past few hours. Just happens sometimes, the Bitcoin network has a mind of it's own.

It's nothing to worry about, it'll be back to normal v.soon I'm sure.. from my experience there is a block holding it up with a bunch of transactions in it - once that block is finally solved the bottleneck (for want of a better word) will be clear and it'll all flow smoothly again.

yet just 12 hours ago someone was complaining of the opposite


bitcoin is not a strict 10 minute rule.. its a fluid(average) 10 minute rule.
if theres a influx of fast block creation, then there will be a time of slow block creation just to balance the system.

and to add ontop of this. some pools are greedy and make 0 fee transactions wait longer (hate greed)

Did you add a fee ?
if not it can take a while... if you did sometimes it takes an hour (but not usually) for a block to be found...
6 confirms can actually take quite some time..at times.. but it sounds like you are just wanting 1.
I am about to goto bed but post up the transaction ID and I am sure someone else will be able to assist and tell yoy if there is a fee or what might be happening.

its just you.

...is it taking longer for Bitcoin to confirm payments? I've been sitting here for about 45 minutes waiting for a recent payment to come through and not much going on. It's not a lot, but still...
