Added to my list of Mother of all spam attacks (https://bitcointalk.org/index.php?topic=1776143.0)

I can look for more addresses, but it is too boring...

https://blockchain.info/address/1F2YvHS6zJv4jTqFgMM4erUXcRXH8W798u?show_adv=true

Are these your addresses? It looks like the fees used in some of the most recent (and unconfirmed) transactions are very low, and will likely not confirm until the current backlog is essentially eliminated.

someone please tell me what it is? I found these very small transactions here, what is it? why is there such transactions? and why do you call it spam? this means that the transaction is not due to you, silly. I think that is the cost for any transaction of you. I've never used blockchain, so I do not understand much about it

Why do you care about this spam?
Spamming the network with such transactions is pointless.
Somebody is wasting  time and efforts for nothing.

No. I do not waste my funds for nothing. If I would want to spam blockchain for any reason
I will not publish my transactions on forum.

Why do you think that I am responsible person for all bitcoin problems?  ;D
Such spam is the reason of current backlog

I don't care. I only published it for others who may care.
Nothing is pointless.
Wrong

I wonder when the asking of right questions start. questions such as how to fight these types of spam, not just this new method of big transactions spending multiple inputs but also the older ways of spamming regular looking transactions every 2 seconds transactions that spend 1 input and have 1 or 2 outputs.

Probably by adding a few restrictions on what people can do with the chain.Limiting their access to the network or verifying the outputs before the transactions are broadcasted.But that would take the 'open-ness' out of the bitcoin source and people would call it a more centralized thing.

Lol, I don't blame you for all of Bitcoin's problems. I do know you well enough to know that you are a Bitcoin expert who likes to profit off of vulnerabilities -- I also know that you have your own unique way of making problems/flaws in various systems public. 

I disagree. 19yj1mUuA6nAoCRVvPY7Wo8MmBc9jPJBpo for example is spamming transactions with an ~12 sat/byte fee while others such as 17bgX68iQZW4RxeQTSw3AZBpboMKjYsscB and 1BMLUBy8MMEmpvudWhHXgnv5VCNr5ZxF3n are spamming transactions with a ~40 sat/byte fee.

It is reasonable to say that there are roughly 10 mb worth of transactions that pay a fee in excess of 40 sat/byte and in excess of 30 additional mb worth of transactions that pay in excess of 10 sat/byte (I do not have a breakdown in increments less than 10 sat/byte). source (https://jochen-hoenicke.de/queue/24h.html)).

It will take more than 10 blocks to reduce the mempool so that miners are confirming 40 sat/byte transactions because new transactions are being broadcast, and users will reasonable pay market rates for tx fees, which are above 40 sat/byte, and any transaction above this rate will result in this backlog not declining.

It's the free market, people have the right to do anything if the follow the rule.
There is no rule to forbidden people do such things.

Nothing surprising, happens every time when there is a backlog. Somebody (who is currently pushing for large block sizes) tries to make the network unusable to force bitcoin to increase block size so it would be even easier for them to ddos the network with huge cheap txs and eventually kill bitcoin. But they will fail as they always had )

The beauty of decentralized system? NO?  The current blockchain spam is very annoying, affecting people that has little to no technical knowledge on Bitcoin.  Not all bitcoin users have the knowledge about the transaction fee adjustment, and this spam may give them trauma (first time experience in Bitcoin transaction and a result of days of waiting since they have no knowledge about tx fee competition) .  This might be funny but it is true.

I disagree. Because you making a wild guess.

I find these facts, kindly correct any of them that are wrong:
* In the past 7-8 years blocks were empty
* In the past 7-8 years txs were cheap even free
* Nobody ddos the network!
* They are spamming with 100,000 transactions (50 MB to 70 MB) http://statoshi.info/dashboard/db/memory-pool past 7 days
* What you said is only true if we increase the limit to something such as 10 MB or more

Today, free for send BTC highter than befor many

The blocks weren't empty. There's always the coinbase transaction and other transactions. The transaction fee has always been there, as the adoption rate increases, it will rise.

Bitcoin is still usable, just pay a higher fee. Increasing the block size will make it much more expensive to impact Bitcoin at this scale.

Right, I don't know for sure. What I know are facts, and they are - this is not the first and not second ddos attack; they been going on since bitcoin classic and the block size debate started. Every time there is a slight congestion, or a difficulty adjustment, network gets attacked. So your facts are incorrect, somebody is actively trying to prove their point or just harm bitcoin adoption. Even 2x block size increase will make such attacks much more dangerous and heavy for the verifying nodes, in effect block size increase could allow the attacker to kill the network nodes with specially crafted txs like these. But the layman would be requesting block size increase seeing so many transactions, and thats what the attacker is hoping for.

Good thing that bitcoin developers are smart and can continue securing the protocol under such an immense pressure.

These were just the small transactions with decreased fee. It all happens with user requirements. If they doesn't need a short time confirmation would go for these transactions. Few websites provide prioritize transactions with certain fee amount. This too might be a part of those addition.

Indeed, all addresses spotted here are not spamming but used by komodo notary nodes

And what is the difference? ;D

Komodo is using the bitcoin blockchain to notarize KMD transactions (dPoW)
not spamming to try to chrash the BTC price or promote segwit or who knows what.

It's great to hunt spamming tx to figure out what is happening on BTC network, just saying you can ignore those addresses for your hunt  ;)

The email spamers are using Internet infrastructure for advertizing buisnesses.
Nobody says that they want to break Internet down :) and force users to use another ways to communicate.

But email letters are spam for receptients.
And komodo transactions are spam from bitcoin user point of view.

Ok I got your point :)
To explain it, i saw a mention of this thread initially on https://bitcointalk.org/index.php?topic=1776143 so my intervention was mostly to tell people that are searching for spam attacks to ignore the addresses mentioned above.
By attacks i mean actions to affect BTC network on purpose.

Now, even if i like your analogy, considering that komodo transactions are spamming the BTC blockchain is indeed a question of point of view...

Hopefully there won't be other coins that decide to do things like this in the future; blocks are already full enough as it is and we don't need more txs on the chain. Komodo had a great initiative but it's just bogging down the bitcoin blockchain with its method of tx verification.

Disable free transactions or have a master node(like GOLEM) which is a decentralized super computer to filter low fees or no fees transactions.

yea those people have some sort of enemy with bitcoin and may be they belong to developers group of other altcoins. To slow the network bitcoin they might create such havoc condition.

I can imagine some altcoins have an interest in seeing the bitcoin network harmed in any way.
Not many really because they are mainly traded against BTC currently.
And certainly not komodo because it offers a service that rely on it.

When a company's website has lots of traffic, you don't tell the user's to stop using it, you upgrade the server right?

Utility gives value, otherwise bitcoin would be at 0 still.

This is the major difference between centralized and decentralized technologies.
Your advice is for centralized buiseness.

I think it is have a relationship with this.

https://bitcointalk.org/index.php?topic=1737342.0

There is no difference. In a centralized environment you increase the resources, in this case BTC increases the block size. Everything is a choice.

Correct. We are accounting for about 0.2% of the tx's maybe so not really a huge deal.

Speak for yourself.  I am a bitcoin user and I don't consider these transactions spam.   Anyone is free to
use the network as they want.  That is the very essense of 'permissionless'. 

Those are the addresses being used to hide a spam attack on the Blockchain. These guys know that we are operating on a network, where most blocks are about 80% full, so they just spam the network with useless transactions to fill up these blocks to cause backlogs and severe congestion.

The motives is unclear, but people seem to think that it has something to do with SegWit or BU where a "fake" congestion is being forced onto people to get them to make a decision and to break the gridlock.

Others seem to think, miners are behind this. They create a backlog and then people will pay higher miners fees to get their transactions confirmed. This leads to more profits for them.

What a sad situation for everyone else to see this technology being manipulated by greed.

wow very interesting and  didnt realise this is going on..unbelievable

I would at least people look through this thread to see these miners fees being paid by Komodo notary nodes to recycle the hash rate of the bitcoin network to protect the Komodo chain.


Www.komodoplatform.com and checkout the white paper.

We have been doing this since Oct last year consistently. We use the Bitcoin network like any other user. The short sighted view that we are spamming the bitcoin network is crazy, we are paying fees for txs. If it can't handle the amount of txs it is a problem for the network, not of its users.

I deeply know that spamming blockchain is a harmful things that people do to bitcoin and that will be reason why take times to get confirm a transaction. But I don't know that why do they do that? They want to crash blockchain down? or want to delay the transaction to get their purpose (I mean if a trading don't confirmed too long - about 48 hours - the fund will be send back to sender right?). And how can you find these transaction, how about detect it and report to blockchain developer?

if you think about it, in the centralized environment there is not a single person that take the full decision about a task, for their service, they always consult between 10 people or s

it's not very different than miners deciding about the future of bitcoin, it's just more hard because of 10 people we have 100 that need to decide...

of course. "centralized" != "one person"

does not matter how many humans work for a service
from the point of view from the rest world there is centralized service "facebook" and a billion of users connecting to it
how many employees work for facebook is not an agrument to think that facebook is not centralized

Today bitcoin is not decentralized. So, 10 pool admins can make anything.
Either increase block size or ban some addresses which produce too much traffic

There are several in here that accuse the Komodo notary nodes in their group-signed transaction of contributing to the delays on the Bitcoin Network.  This is not the case.  First, our transactions count for well less than 1% of the current backlog. In addition they are a part of a necessary function in the SuperNET ecosystem aimed at enhancing the bitcoin networks scalability.


Everyone has heard of the block size debate and its proposed solutions.  Whether you are a proponent of SegWit + LN or BigBlocks or some other method in-between, most all can agree something needs done.   Komodo aims at tackling current and future need for storing data on a secure distributed ledger  through its scalability mechanism  known as " Delayed Proof-of-Work ".

Delayed Proof-of-Work  works by receiving submissions from third-party blockchains and recording their hashes into a Komodo Block.   The blockhash of that block  is then submitted in a group-signed transaction to Bitcoin's Network through a group of elected node operators.   This signed transaction forms a "checkpoint"  where if at a future time either a third-party blockchain or Komodo itself  becomes threatened by a malicious actor or a fork divides the community, this checkpoint system gives the operators of the respective networks a " last known good" block hash  from which they can start efforts of fixing their network.  


The Delayed Proof-of-Work system  is already securing more than 36 blockchains!!!  


For an attacker to totally compromise Komodo or the independent block chains that it secures  it would have to undermine bitcoin's security,  which is an extremely difficult if not impossible feat.



Delayed Proof-of-Work acts as a scalability mechanism  in the sense that developers can develop blockchain based projects, in full control of their own blockchain without being restricted by the technical and political limitations of bitcoin or other parent network   while at the same time  benefit from the security granted by the incredible amount of hashing power that is used to secure bitcoin.

It could be a group of miners making a fee market. As difficulity gets higher and bitcoin's estimatefee function provides inertial values, they can dissolve some of their BTC mined to the network while part of these fees are recycled back to them. Recently, there was 3.1 BTC (roughly $3500 now) in fees as seen in block #455009.


Probably it is carefully watched process as they don't want to get mempool size over 300MB (when throttling by mempoolminfee is triggered) and on the other hand not to let fees estimation drop too low.


Of course, activating segwit or increasing block size is in such case counterproductive.

Bitcoin lacks a bit of direction in my opinion. As I understand it, the current issues faced by the blockchain are not technical in nature. The problems are bureaucratic.

In the next few years, Bitcoin will see 1000% more transactions. These problems can and should be solved now, before it is too late.

I think this is normal. about transactions that are not treated backlog while all stuck. I think they should like, if we backlog, I am afraid that the trapped will continue to lengthen, and perhaps, the small trading range that is approximately the cost of transaction

You have to understand that others may have other opinions.
And the only way to resolve this in bitcoin style is to vote by hashrate.
How many PH/s do you produce? None?
Your voice is too weak it can not be heard.
Your opinion nobody cares

There are no technical problems. Every problem has the First Name and Last Name.

I doubt.

You are welcome to start solving these problems.
Dont waste time posting here. Solve them!

Good catch !
