60,000 Unconfirmed transaction and counting

[jonald_fyookball]

Things are definitely better then It was yesterday, I have a question though, If this is indeed a spam attack, anybody could do it? or this require money and resources to do? curious how It's done but If it require money, I believe big whales are behind it.

i am no expert but some things (i think) are obvious. for example the transactions need to be paying higher fees or they would be useless. so each paying 200-300 satoshi per byte.

only useless to real user.   spammer doesnt need to pay anywhere near that cost.  they can put absolute minimum that would be relayed whatever that is (no fee?) im not sure

if there are 1 million transactions paying 10 satoshi per byte i pay 20 satoshi per byte and i will have priority over all of the 1 million spam transctions so miners will pick my tx.

they spam to take the space in the block (fill it up) not to take the space in the memory pool. and to take the block you need to have higher priority hence the higher fee.

you are partially right..but

a)  they can still bid very low and cause problems
b) it contributes to high fees for everyone else
c) the fuller the blocks are naturally, the less extra space there is , so cheaper to spam (this is why bigger blocks will help fight spam)

You would think, but not so.

Bitfury still fill blocks with low fee spam from addy 3QQB6AWxaga6wTs6Xwq8FYppgrGinGu15f before higher fee paying real tx's.
See for example https://blockchain.info/block-index/1477998

Addy https://blockchain.info/address/3QQB6AWxaga6wTs6Xwq8FYppgrGinGu15f has sent 140238tx's, all spam, nearly all relayed by Bitfury.

yes i have seen those before but for every one of these low fee spams there are so much more with higher fees.
and bitfury only finds 11% of the blocks nothing more. so that would be practically ineffective because other miners reject them.

c) the fuller the blocks are naturally, the less extra space there is , so cheaper to spam (this is why bigger blocks will help fight spam)

i find this statement contradictory.
cheaper to spam means easier to make more transactions.

and how much bigger blocks are we talking about!
1.2 MB 1.5 or 2 or 10 MB or 20
are nodes and miners really ready for that size. i don't think so.

But for every one of these low fee tx's (sending nothing exept a fee) included in a Bitfury block, another higher paying fee is not included, meaning fees rise further. 140,000 tx's from 1 addy, sending nothing except low fee, have been included in Bitfury blocks, while "recommended fee" paying tx's (6x higher fee or more) are left in the mempool.

140,000 tx's at 386 bytes equals around 5.5 blocks created by 1 addy, mined by Bitfury, sending 0 btc.
Can't be helping anything.

since you brought this up i went through it and i encountered this:
https://blockchain.info/block-index/1486455 (mined by AntPool)
Ctrl+F the address it contains 252 of these transactions and it seems like bitfury is not the only miner picking these up after all!

p.s. the block was mined during the spam attack while mempool was full (2017-04-15 11:09:19)

You did not "go through it" very far though(?), or you would see that only a tiny fraction have been mined by other pools.
Some Bitfury blocks include around a thousand of these tx's.

p.s. the block i linked was also mined at the peak of mempool backlog.

Lets say that naturally blocks would be 800kb.  If you only have 200kb free per block, and a transaction is say, 200bytes,
thats 1000 transactions.  Let's say people don't really want to pay more than $1 (they can use paypal or another coin),
that is going to cost $1000.

But if you have lets say 8mb blocks, and 7mb are free , thats 35,000 transactions.  So even if transactions are only 5 cents,
it still costs more ($1750).  

Obviously that's just one possible comparison but the more full blocks get the cheaper it gets to spam, that is the principle here.

Yesterday I was transact some money and I have no problem :/ I have no idea there were so many unconfirmed transaction until now. And yes, of course we need bigger blocks because more and more people are using btc and that will be more and more difficult to make a transaction, I hope this problem will be solved soon, especial now, Easter.

ETH probably spamming to promote their awesome blockchain  mean time in BTC idiots are fighting Segwit/notSegwit.
1MB block no limit. ***
When BTC spammed ETH blockchain they forked 2x in 3weeks... Problem solved.
And this is main difference between those coins BTC can be played like children in kindergarden.

[OliynyK]

We need bigger blocks... lets all just run le BU

Hahahaha oh ya but then we'll also have unlimited bitcoins and they're going to be worthless. That sounds great let's all jump on board.

I know it is not a proper solution ,if there is a split then unlimited bitcoins will be worthless and how about the price of bitcoin unlimited futures started by some exchanges basically Bitfinex and HitBTC, did they create some dumb contracts and how about people speculating about that.

That's interesting, can we confirm that by far Bitfury is the only pool picking these up?
As if Bitfury wants to collect their spam fee back.

Time to kill this thread. Unconfirmed transactions down to 6700.

[aomakun]

What exactly is going on here?: https://blockchain.info/unconfirmed-transactions Is it possible that It's some kind of attack from miners to make people think that we need Bitcoin unlimited? Hash rate is no longer being displayed on the first page for some reasons so I can't tell exactly.

naturally a lot of unconfirmed transaction because every day bitcoin users then increases.

That's not what the problem is. The problem is that blocks aren't big enough and people are spamming them so that something will actually be done about it. There's an agenda behind their spamming and that's what this is a discussion about.

well that is the clear difference between a complete decentralized system without any centralized authority to decide whether actiate segwit/nosegwit or anything else.

and a centralized system called ethereum which is performing like a bank and the decisions are made by that centralzied authority without heeding what the rest of the users say.

Very interesting find considering BitFury is the biggest nuthugger of Core/Blockstream/SegWit. Could they be getting big money from the same banks that are funding blockstream to spam the network?

is that the reason bitcoin having so many unconfirmed transactions, to force people to use ETH? which means bitcoin unlimited and/or SegWit have nothing to do so? wow ETH is a troll towards bitcoin for this.

[chixka000]

Honestly, I am starting to hate this kind of situation. I am clearly seeing an abuse here but i cant do anything about it. Because of the slow confirmation must of the online wallets now are offering higher fees(effect would be we can sent micro payments) so f*ck those miners who are doing this act
