It kind of sucks when a small group of people can do this to the network. You sound like you have a reasonable suggestion, but I'm not technical-minded enough to understand it. It would be nice if the people who DO understand the technicals would get some consensus and fix the problem.There's nothing stopping either of you from learning how it works, it's sort of crazy to get involved in something like this and let everyone else do the thinking for you. And FYI, Zicadis has zero clue, adding more pools (or more mining hashrate in general) makes negligible difference to the speed that transactions get processed. If you don't know what you're talking about, please, either learn, or be quiet. Title: Re: mempool 70k+ and growing fast.

Post by: Hazir on April 28, 2017, 10:09:21 PM And now imagine if Bitcoin blocks were 2 MB instead of 1 MB, what will it change against spam attack of that caliber exactly?
It was said that legitimate use of block space is around 70% rest is unsanctioned use - mostly spam. My question: do we have any scaling solution which will take care of obvious attempts to cripple BTC network? Title: Re: mempool 70k+ and growing fast.

It was said that legitimate use of block space is around 70% rest is unsanctioned use - mostly spam. My question: do we have any scaling solution which will take care of obvious attempts to cripple BTC network? It was just a few weeks ago the network was running at like 5% of capacity for days. Its my personal belief the network runs at about 10% of capacity when its not under spam attacks. It's my personal belief the majority of the spam is coming from the Chines mining pools running ASIC-boot. I have zero proof of this but why else would these attacks continue so routinely when we all know they must cost a lot of money; unless of course you're a large mining operation with ASIC-boost. Title: Re: mempool 70k+ and growing fast. Post by: richardsNY on April 28, 2017, 10:54:57 PM Chances are high that this spam attack is coming from the same entity that has been spamming the network back in early February. Quite some addresses from back then are being reused to fuel this spam attack. It's an easy target to point at, but I can't think of an entity that is willing to pump serious money into spamming the network other than the BU gang.
Title: Re: mempool 70k+ and growing fast. Post by: Quantus on April 28, 2017, 11:05:10 PM Hypothetically What would give someone an incentive to spam the network like this?
Could it be an exchange looking to lower the price so they can buy back in? Maybe these spam attacks are even sold as a service to large investors. Mining pools could easily accommodate such an request for a nominal fee of course. "Pay me 'X' and I will slow the network, this will sow fear in the community and the price will drop" Title: Re: mempool 70k+ and growing fast.

Look at the average size of the blocks. Just because the mempool isn't overflowed doesn't mean the blocks are only 10% full. Title: Re: mempool 70k+ and growing fast.

"Pay me 'X' and I will slow the network, this will sow fear in the community and the price will drop" This is part of the political agenda though we do not know who is spamming the network but this is for sure to make the community pressure the developer to either implement Segwit or Blocksize increase. I wonder if one of the two suggestion can halt this kind of attack if it was implemented. Title: Re: mempool 70k+ and growing fast.

I wonder if one of the two suggestion can halt this kind of attack if it was implemented. Well larger blocks would not stop spam attacks or even make them cost much more. But with segwit theoretically companies like mcdonalds, Wall-Mart or even that little coffee shop off main street you like so much could setup a side chains so customers could fund accounts so you can buy coffee every morning with little to no fee and then any money you don't spend at the end of the month gets sent back to your main wallet address at the end of the month. To my understanding thats how it would work. My very limited understanding... The companies would be responsible for security and spam attacks on their side chains.

They would not stop them for sure, but they would make them cost much more since there is so much more block space to fill. With mostly-full blocks now, there's only a tiny amount of space a spammer needs, and after that, they can use the smallest fee possible that would allow a tx to remain in a mempool.

Look at the average size of the blocks. Just because the mempool isn't overflowed doesn't mean the blocks are only 10% full. Blocks are being filled with fake transactions they are not legitimate transactions they don't propagate across the network like other transactions. They are created at the time the blocks are created inside the mining facilities by the miners to facilitate an efficiency boost for miners. (google ASIC-boost) And increasing the block size would have virtually no affect on spam attacks, if you doubled the block size it would just make it cheaper to send transactions thus making it cheaper to send spam. https://i.ytimg.com/vi/6chkGsc-0tY/hqdefault.jpg And just like that it looks like the attack has stopped or maybe just taking a break, I wonder how long it will take for the backlog to be cleared.

It would actually make it worse. They would be able to make much spammier transactions due to the quadratic hashing problem (which segwit fixes) which could cause chainsplits.

Not necessarily because lets say the fee was cut in half with double the number of tx... if blocks are 90% full on average, the extra 10% is all you need to overflow... so its a 1:11 ratio. You would need to have fees get 1100% cheaper before it would be the same cost. Title: Re: mempool 70k+ and growing fast.

Oh there is ! it's called Segwit but it's not yet implemented because people chose to debate over it and not actually test it to some altcoin. Maybe one day the community will have an actual consensus when it's all to late for this crypto currency. Title: Re: mempool 70k+ and growing fast. Post by: pooya87 on April 29, 2017, 04:02:57 AM This another spam attack? Looks like it started 4 days ago. http://statoshi.info/dashboard/db/transactions to be fair the spam attack started at least 2 years ago and only had some breaks in the middle to rest and gather all the small transactions in one address to start spending (spamming) again. this spam attack seems to be working...i have had a couple of transactions fall off and viabtc.com/tools/txaccelerator/ keeps notifying me that transaction does not exist there are two possibilities that i can think of without seeing your transaction1. your transaction did not reach viabtc when you used them which means you should have waited a little like 30 seconds! 2. your transaction was rejected by viabtc node so they say it doesn't exist. (i have experienced them rejecting my secondary RBF tx with higher fee) Just out of curiosity with such huge backlogs why dont we have more mining pools created to help alleviate this tx problem we facing ::) that is not how mining works. even with more mining power there still would be the same blocks being mined within the same time frame.Title: Re: mempool 70k+ and growing fast. Post by: bitart on May 07, 2017, 09:53:20 PM It seems that mempool has recovered to the ~50% of the last day's peak, at last... (55k instead of 96k)
It's still huge but I was wondering how long can the demand/spam attack fill the mempool with such a high transaction quantity. It seems that this extra high peak has gone, but we're still above the average, and if we have a look at the 60 days chart, we've only dropped back to the highest peaks of the past 60 days. It can be the demand too, that causes the increase, I remember in Feb.2017 Trezor shop has run out of stock because of the high demand from Japan and from the rest of the world... Maybe people in Japan started to use their new Trezors :) |
