BITMAIN announces Antpool

[btcash]

I support increasing the block size. @BITMAINtech 's AntPool will be prepared to switch to XT, IF we see majority has switched.

The pool with the most (absolute and relative) empty blocks supports blocksize increase..

BTW: Chinese pool operators shouldn't side with Hearn. He has made it obvious that chinese miners should fuck of if they have poor connectivity.
Not saying he is wrong.

Of course, it's easy to support a blocksize increase if you're willing to use SPV mining instead of running a proper full node at all times.  It also helps when the majority of the hashrate is local to your country's shitty internet giving you an advantage in orphan races caused by larger blocks.

look at you guys crying like a bunch of babies lol lol lol.

Sad to see that so many bitcoiners have so little brain capacity to get what is at stake here.

Care to explain this comment more?  Are you saying miners at antpool specifically?

Or in general bitcoiners?  I'm a little lost.

At least on my end:  It's because Antpool (and unless they changed, Discus Fish/F2Pool as well) still engages in SPV mining, meaning that they are not relying on a fully validating Bitcoin node to mine.  Which has caused them to fork the chain once in the past already, and means that they mine empty blocks at a significantly higher rate because they will move on to a new block header before their bitcoin node actually sees a new block.

SPV mining is something that people should NOT be okay with.  There's no excuse for it, and it is directly harmful to the network for such huge amounts of the hash rate to be mining on pools which will start mining a new block without validating the previous one.

Thanks for the explanation.  I have to admit that does sound scary.  Is there any stats or anything where we can see how often it messes up and goes to new block? Do they show as Orphaned?  Or would these non validated blocks show up as something else?

And thank you for your time explaining it.

https://bitcoin.org/en/alert/2015-07-04-spv-mining

It's only happened twice that I know of, both times were luckily caught early, though the first incident was 6 confirmations long.  One thing to note is that the "1 tx blocks" that AntPool, F2Pool, BTCChina, and a few others generate are the result of SPV mining, which causes transactions to take even longer to confirm because the pools aren't doing their jobs of processing transactions.  SPV mining is shortcutting the validation of blocks in order to try to gain an extra second or so of mining time on a block switch, but it can only be done by building an empty block based on the last block header (which is *assumed* to be a valid block but as we saw in July, isn't always the case).  

Note that if you're saving 2 seconds on every block switch, you're going to get about 0.3% more mining time in the long run (2 seconds every 600 on average).  The tradeoff is that you're slowing down the network's ability to process transactions by sending miners empty blocks.

As Kano has pointed out in the past:  Properly optimized pool software running on good hardware makes more impact than SPV mining.  CKpool and BTC Guild were frequently able to push work out for a new block faster than pools that use SPV mining techniques, and neither of us had to resort to short-cutting block validation in order to do it.

Greetings from germany,

why we get so often Orphaned blocks at this times?

377924   2015-10-08 02:26:26 Orphaned
377896   2015-10-07 21:26:48 Orphaned
377837   2015-10-07 10:54:27 Orphaned
377816   2015-10-07 07:47:47 Orphaned
377815   2015-10-07 07:31:52 Orphaned
377811   2015-10-07 06:50:36 Orphaned

@Antpool Team, it is possible to fix the core...

Best Regards

good going SHITMAIN !

[armedmilitia]

antpool.com down for me.

I checked on http://www.isitdownrightnow.com/, and it seems like it's down for everyone!

Edit: Site is back up, downtime was maybe ten minutes.

It has to do with the pool code, if it's optimized to get solved blocks and work out quickly, block change time, internet connectivity/latency of their mining operation.

Kano and Ck have done a lot of work on their pool code to avoid orphans and empty blocks, you could always try mining on a pool run by people who actually care about the bitcoin network:

Blocks are lost a few ways:
1) The obvious network orphans - fewer means a better connected pool
2) The hidden pool orphans when the bitcoind test says it got a network block, but the pool got it's block just after that, but before the pool software knew about the network block change (these show up on our pool - our 2nd orphan was like that - but most pools don't show these)
3) The lost stale blocks due to processing of work by the pool being too slow after a network block came in - due to slow pool processing
4) The lost stale blocks due to the miner getting the block to the pool after the pool knows about the next network block - due to a slow miner network, a slow pool network or slow pool processing

Just to let miners know, Kano and I worked on minimising the latency of bitcoind under the current flood of transactions and I'm happy to say that we've been able to deploy some of my custom modifications to this and solo ckpool which still guarantee maximum transaction processing (i.e. never a zero transaction block) while minimising the risk of stale work / orphans. Plus we are NOT using a transaction blacklist; all transactions are prioritised on their own merit as per bitcoind rules.

is it my imagination or is antpool taking longer to pay out ?

He forgot to mention the driving force behind it. One that transcends technology.

Lately, depends on the day.

I see Antpool gave us 10m, 30m, 1h and 1d averages back.

[willi9974]

why does it take so long, or if the block again Orphaned

[yslyung]

why does it take so long, or if the block again Orphaned

you can check on blockchain data. i think only 1 block is orphaned & it's not updated yet same goes to account balance.

Hello, what is with the Antpool Earning History, last block earning for some hours on block 379194, but 6 other block found and confirment...?

nothing changes since 5-6 hours... 

[paputa]

i know with ghash have 10 turns/shifts each turn= 1 hours
and i will paid for only 10 turns open ok
but for antmine?
I see

   
Earnings = 25 BTC * Your share count in 2.5 difficulty cycle / Total share count in 2.5 difficulty cycle


what is 2.5 difficult cycle?
thank you





and i have mined for few hours but when i found the block i don't received anything,why?

It usually takes a bit for the block to confirm.
