Topic: Bitcoin Block time - page 2. (Read 549 times)

So the fee was 6000 sat per kB. I think that is ok.

I tried to use Lightning network, all wallets even the offcial one I used were "not compaible" to the test I made (this picture you can paint for 1 sat per pixel)

What is the real difference. Some special nodes confirm the transaction faster like instant send in Dash?? Thats it, nothing really special 

This probably happened because you have picked a fee which was too low.
Usually 1 sat/B transactions get confirmed pretty fast, but the mempool started growing a bit today. This happens in cycles.
You can check the current status here: jochen-hoenicke.de/queue/#1,8h.

How high was your transaction fee ?
If you really need it to be confirmed as fast as possible, you might bump the fee (assuming you have the RBF-tag set; depends on the wallet you are using).




Bitcoin is the most proven and secured payment system around.
Each other crypto is either a clone or some untested system which massive vulnerabilities.




The LN is completely different from master nodes. You seem to have a misunderstanding of the LN.
If you want to get a deep understanding you might read want this article (part1 , part2).

If you instead don't want to spend 15 minutes of your life, you might look at the wikipedia article instead.

Both sources should make it clear that the LN in not similar to the concept of master nodes.

But today again same problem I really hate that. I send a transaction with normal fee and now waiting at the computer for about 2 hours and it is still not confirmed.

Why all crypto people use this Bitcoin Bullshit for payment. Yes for payment in Crypto it is bullshit.  

And dont tell about Lightning, this is child foot age. And nearly same as Master Nodes.

Variance happens, difficulty has little to do with. Reducing retarget times to timeframes of eg. 1-2 hours you'd lose most of the network's reliability, stability and security.

Case in point: When Bitcoin Cash hardforked last year, they started off with retargets every 144 blocks (= one day). The result was a clusterfuck of hashrate oscillation between Bitcoin Cash and Bitcoin. Sometimes Bitcoin Cash would have a block every minute, causing the retarget period to only last a couple of hours. Sometimes Bitcoin Cash would swing towards the other extreme and have only 1 block every couple hours, practically grinding to a halt for days. So in a way Bitcoin Cash was the first coin to introduce banking holidays to cryptocurrencies. Joking aside, the latter was incredibly annoying, especially since many exchanges had to up the minimum required confirmation count to 12-24 confirmations, due to the questionable security and stability of the Bitcoin Cash network.

In other words, there's a lot of side effects to keep in mind. One may argue that 2 weeks are too long a timeframe, but a certain margin of error is required as to avoid hashrate fluctuations. Then again reducing the timeframe to other conservative timeframes, like for example 1 week, you'd still have variance in block intervals like you experienced.

It is also worth noting that for the most part of Bitcoin's history it's been ahead of its block intervals anyway. As the network grows, block intervals are on average shorter each difficulty period as they should be. Hence difficulty increasing. Hashrate being added to the network actually reduces the block interval within each period. It's only that at the beginning of each difficulty period the network adjusts back up to a block interval of 10 minutes.

Why are there more miners entering the market? Well, likely there's still profits to be made if you're able to minimize costs at the right corners. Old mining hardware may be phased out and replaced by more efficient and powerful miners. Old mining hardware may be bought up and brought back online by newcomers who have no idea what they are doing.

Yes difficulty must be addapted more fast.

And why not halven block time and reward ?

Lots of options for reducing the retargeting time, Even keeping the same difficulty protocol I think lowering it to 1 Day (360 blocks) would be plenty.  Reading old posts people were worried about crazy difficulty oscillations, but DarkGravityWave doesn't seem to have that and it retargets every block.

Want to send some BTC, now over 1 hour no block found.

For payment in  just NOT to use

The network behaves as it was initially designed. Every 2016 blocks there is a retarget, the difficulty gets adjusted upwards or downwards so the AVERAGE time between two blocks is ~10 minutes.
You are correct tough, if the networks hashrate would drop to 50% in the first 10 minutes after a retarget, it would take about 4 weeks untill the next retarget, at which point the time between two blocks would once again be ~10 minutes. This is still "working as designed" tough, theoretically, there is no problem... Sure, blocks would probably be completely full for the next 4 weeks, a fee war could start, it would take a longer time to get a confirmation,.... But everything would sort itself out, without technical problems.

The fact that at this moment, the time between the last 6 blocks was ~20 minutes (i didn't verify this): no problem, it's completely possible... That's why the difficulty is adjusted so the AVERAGE time between two blocks is ~10minutes, and that's also why we don't retarget every 10 or 20 blocks (if we would retarget to often, the difficulty would jump up and down quite a bit, since the number of samples would be to low).

Solving a block requires the miners to increment a nonce in the block header, then create a sha256d hash of this new header and check if the result in under the current target. It's possible that after a miner receives a new block and start working on the next block, he finds a header whose sha256d hash is under the target in less than a second, it's also possible he'll never find a valid block...

Ok, but when there are "waves" of hash rate in the two weeks, the coin can not adapt.

Depending on BTC.com the difficulty will rise about 3 % in 6 days, but as I said at the moment 5 to 6 Blocks in 2 hours....

It's not like that.
Bitcoin mining is designed to adapt to the total hashrate of the miners based on the previous block.
The difficulty will always change to maintain the average of 10 minutes per block. "Average" means that sometimes, it doesn't guarantee that the difficulty can accurately "harden" the block discovery.
So sometimes, a new block was discovered in less than 2minutes, sometimes, it can take 30 minutes to mine a block.

I am really wondering about BTC Block Time.

This morning only 6 Block found in 2 hours. Of course it depends on luck. But it depends also an HASH Rate. This is so enormous high and only adaped every 2 weeks.

Why does the biggest coin does not solve this difficulty problem? And why still more and more miners start so that the difficulty rises without watching the price.
