solex, where do you go to get your mempool size info?  there seems to be discrepancies btwn sources.

Lately I am using tradeblock as their site is fast and informative. https://tradeblock.com/blockchain
For some reason the leadership at blockchain.info has become rudderless and their site is often not keeping up and development there seems static. My impression anyway.

you're referring to the 1MB single tx block that f2pool constructed as a non std tx to help reduce the UTXO set?

why was that a bad thing?  it was a one off to help consolidate all that dust and required that a miner self construct this type of block and transmit it.  that wouldn't be a repeatable, viable attack to inflict on the network by a rogue miner looking to gain an advantage over other miners for the following reasons:

1.  constructing an 8MB bloat block while the rest of the network is making 1MB blocks runs the severe risk of orphaning
2.  if the pool consists mainly of hashers, they would react by redirecting their hash away from the attacking pool to preserve the network
3.  if it was coming out of China from a large miner, that miner runs even more risk of orphaning due to the GFC.
4.  other miners receiving such a bloat block could react defensively by switching to mining a 0 tx block during the validation process.
5.  game theory suggests a miner wouldn't even begin to do this attack for preservation of BTC value and his hardware investment.

Yes. The block which reduced the utxo set. That was the good part (though Greg posted on irc that it could have been constructed much more efficiently). Anyway, the bad part is that validation took 25 secs (because of all the inputs). Bitcoin full nodes have no way at present to look at a block and decide to orphan it in advance because it is a "bloat block" that will take too long to validate, they will all chug through the block first.You are probably right bloat blocks would not propagate fast enough and get orphaned.

here's a subtle theory i have as a result of that 1MB tx block.

i think the only reason an attacker would even try that type of bloat block to try and choke the network is if and when all other miners are creating similar sized blocks; like the situation we have right now with full blocks.  that way, it runs less chances of being orphaned (which it wasn't) b/c it doesn't stand out in the crowd of other 1MB blocks.  but if we went to no cap tomorrow, trying to attack with a huge bloat block while everyone else is still at 1MB blocks would stand out. all other miners could then react defensively, if they so chose, by mining 0 tx blocks during the 25 sec validation period.  or, more likely, it would just get orphaned. thus, any attack would fail with no limit.  afaic, there weren't any defensive 0 tx blocks mined after that 1MB single tx block b/c none of the other miners were particularly threatened by it as they were also mining 1MB blocks.   then, it would be quite likely their hashers would abandon them for egregious activity perpetrated against the network good and destroy them like they did with ghash.

IOW, what i'm saying is that there will be a tremendous incentive for miners to stay together near the average block size across the network even w/o any cap at all.  if they all decide to create larger blocks, fine, they advance to bigger blocks together as most miners are honest.  that would be a good thing.  the majority of them don't want disruption.  spammers would even get wiped out in this situation if the miners in aggregate decide they can handle the spam.  which they would by assessing full node functioning across the network and examining their own internal capacities along with user fees and access.  spam would even help strengthen the mining industry unbeknownst to the spammer by feeding revenue to them while desperately trying to jack mempools and disrupt users.  and IF by chance spammers do start to jack the mempool, then miners can simply dial up their minfees to choke them off.

no limit is the easiest most straight forward way to short circuit the spammers ability to disrupt the user and jack mempools.

i'm glad the VC's are starting to focus in on what the real problem is:

https://a16z.com/2015/07/13/a16z-podcast-bitcoins-growing-pains-and-possibilities/

Oh how nice to hear the view from 2865 Sand Hill Road, courtesy of In-Q-Tel (AKA CIA) partner A16 and Hearn@sigint.google.mil.

27 seconds in, and we've already being treated to hard-selling, counterfactual exaggeration in the form of "there not much time left to make changes before Bitcoin blockchain capacity runs out."

"1MB kludge"  No, wrong, a sanity check/DOS regulator is not a "kludge." 

 Angry  FFS, I'm struggling to not attribute to malice what can be explained by ignorance, but Hearn should know better.  Especially as Gavin as told us the sky will not fall because of full 1MB blocks.

Please tell us how you see Bitcoin growing, and how you propose to prevent DOS by limiting block size, this seems like an oxymoron to me.


I'd also like to highlight a point that reflects ignorance on how the economics of Bitcoin incentives work, it is repeated by the "lets limit block size for now proponents", and that is that transaction costs are unrealistically low, or the cost of a transaction is not reflected in the TX fee or the market for TX fees is insufficient to sustain Bitcoin and this is a problem.

Bitcoin has been undergoing massive inflation, that inflation is subsidizing mining. Miners are being subsidized to grow the network infrastructure with a 25 BTC block subsidy every 10 minutes. This subsidy is an empirical part of Bitcoin and it is gradually removed in a disruptive but constructive manner essential to Bitcoin's growth, it has another benefit in that it reduces the cost of TX fees, and grows to protect the value stored in the network while it is small and vulnerable.

It is dishonest to claim transaction costs are low without pointing out that they are being subsidized and the subsidy is designed to reduce over time slowly enough to allow market driven prices to evolve.

It is also premature to centrally enforce protocol changes to manage or manipulate market driven transaction costs while those invested in Bitcoin are subsidizing the inflation and the actual cost transaction cost.


blocksize has nothing to do with DDOS.
transaction fees, on the other hand..
they are just bound to skyrocket at some point - but that would ensure safety and integrity of the network, regardless of blocksize.

bitcoin is a privilege, bitcoin is a worldwide decentralized network.

it wont save neither greece, nor the "africans" (such fucking racist argument BTW..).
you wont be able to buy frappucinos with bitcoins, nor any other immediate useless consumption carp..

geezuz chr*st.  the whole thrust of this thread is about Bitcoin replacing gold as a worldwide currency and as a new form of Money for the Ages.

for it to do that, it must replicate what gold has done for thousands of years.  and that would be to function as a liquid money for everyone.  yes, even those little African kids who are digging it up out of the ground as we speak.  if it doesn't do that, then Bitcoin will forever be competing with physical gold and never get the chance to ascend to the throne, so to speak.

even if you disagree with that concept, wouldn't you agree that that would represent the ultimate in decentralization and security for Bitcoin if used at that level of the masses assuming it could be achieved technologically?

if financial elites like Krugman believe users/participants are the key to Metcalfe's Law and growing the internet, then Bitcoin should be employing strategies that attempt achieve the opposite of what he believes; grow it's users/participants:

The growth of the Internet will slow drastically, as the flaw in “Metcalfe’s law” — which states that the number of potential connections in a network is proportional to the square of the number of participants — becomes apparent: most people have nothing to say to each other!

By 2005 or so, it will become clear that the Internet’s impact on the economy has been no greater than the fax machine’s.

iCE called limiting block size "a sanity check/DOS regulator" you say it has nothing to do with increasing transactions ie DOS but more to do with transaction fees, (which are heavily subsidized) at this point in time.

So why do we need to "limit block size for now" in that case?

I don't see the mechanism that will make transaction fees sky rocket, the only one that will function in a free market is limiting block size.

The next question is why do you think that's a good idea?

I'd say your suspicion is likely correct.  The part I was listening to when I pecked out this note was the guy explaining away the 'privatized gains/socialized losses' in the mainstream system as being associated with spreading the cost of theft and fraud around.  The guy completely neglected what I suspect to be the major cost in mainstream-land which would be the cost of spying on and regulating individual users at the behest of the govt.  There are good reasons to ignore this cost from these guys perspective because they expect to channel Bitcoin into an evolutionary path where it does this only better.  Whenever I hear someone make a big deal about standard Libertarian principles but subtly leave out large and important blocks I get suspicious.

Distributed crypto-currency solutions have the potential to support 'the masses' no matter what their position in life by taking over certain functions of government when and organized and 'standard' government fails to serve the people.

Bitcoin will hopefully end up being a part of this process, but will fail and will in fact become part of the problem if it is subverted.  The most likely way this subversion would happen would be that it is induced to outgrow itself and centralize.  That concept is the source of my desire to see things 'go slow and with caution' with respect to the blocksize (and other things.)

In other words, it is absolutely the lesser of two evils to reserve the use of Bitcoin itself to those who are positioned to support it in a net-positive manner and plan on Bitcoin being a key element in a foundation upon which solutions which can realistically support disadvantaged people can be built.

To me, and I suspect many others, the 'restriction' in native used of Bitcoin via fees or anything else is pretty much exactly the opposite of 'screw the masses'.  It's just that there is an added layer of complexity which might make it look that way to the casual observer.

another productive member of society dispersers into the wild after realizing bitcoin profit, while he doesn't buy coffee with Bitcoin ( unlike Adam Back who advocates bitcoin should be good for coffee) it's unclear if he left the proverbial note: "Who is John Galt?" before embarking.

I agree that 'bitcoin should be good for coffee' with the caveat that it should be done (in cup-sized quantities) by use of a proxy.  Exactly the type of thing that Blockstream seems to be working on in fact.

It will propagate just as fast as the other blocks, the size is not the issue so much as the construction.

This issue arises when larger blocks are permitted.  Though even at 1mb block construction can be made to be disadvantageous to other miners in order to increase the validation time.

I am not pretending that there is no resolution to this, only that there is not yet one implemented.  It is more important to develop in order rather than rush in a fix to 1mb block limits for which we are not ready, or one which is poorly designed.

the above 2 statements appear to be inconsistent.  the bloat tx does indeed take longer to propagate; 25 sec:

Rusty got a bit overzealous in his pessimism as was pointed out in the comments by Dusty, who may be the Dusty who pops in here every once in a while:

In fact not: if a block takes too long to be verified nobody builds on it and your block get orphaned (miners build only on blocks they’ve verified… or at least they should).

So you lose the time you hashed and your reward: next time you’ll probably learn the lesson and create a smaller block Smiley

I am not pretending that there is no resolution to this, only that there is not yet one implemented.  It is more important to develop in order rather than rush in a fix to 1mb block limits for which we are not ready, or one which is poorly designed.

i wonder if that is true.  it's possible that everything exists in the protocol now along with the game theory, as it stands, to encourage miners not to bloat blocks for the fear of orphaning and preservation of network value.

I see your confusion.  You've confused propagation with verification.

Again, this isn't about creating a too-big block, or even an especially large one (though the larger it is the longer the verification time can be).
It is about creating blocks of acceptable size with valid but complex transactions.

Yes, other miners may decide to implement some trap for blocks that take a long time to verify.  Doing so runs the risk that not everyone else will do that, and get stuck mining on the not-longest chain.

If the block is discarded and they continue on the previous, then they are forking at risk of orphaning.  Either way the miners have a risk and the complicated TX miner has an advantage... unless everyone does the same thing (and they won't).

Looks like miners are refusing to process spam. A lot of small blocks 130k-250k

that is evidence that miners can indeed control spam or bloated blocks that attempt to attack the network.

lift the limit entirely.

lift the limit entirely.

This is also evidence that we are currently using 20% of network capacity. (and 80% of load was only temporary spamming)

does your above argument depend on the existence of the relay network or not?
