141  Bitcoin / Bitcoin Discussion / Re: Why the Bitcoin rules can't change (reading time ~5min) on: February 28, 2013, 01:28:22 AM
I'm part of that sticky group of people that WILL NOT accept a larger block size.  I doesn't matter what other people say; or the reasons that they give.  Frankly, I would reject (with my full node, and SPV nodes) any non-bitcoin chain.  Any block breaking the 1mb/10min avg limit will not be a bitcoin for me.
If they developers commit to scaling the network as far as the demand for transaction requires so that it can be the replacement for PayPal, and for Visa, and maybe even national currencies that we've all been promised, then I'll start up an extra full node to replace yours.


That isn't the point either.  The fact is that my nodes will continue to run quite fine; rejecting your blocks.  I will be using bitcoin, and you will be using some alt-rule-chain that I don't consider to be bitcoin.

My coins will be spendable in both chains.  Smiley

The thing is that if 10% (or even 1%) of the Bitcoin USERS do not accept the change, the change will not happen: because the economic consequences will be too-large.


We are not working in a democracy here.  We are working with a "do what the you want, but I'm not going to change my code mkay."
For this change to be successful, the bar isn't 50%, or 90%, or 99%, but rather closer to 99.9%.

So yes, I think that there is AT LEAST a key 10% of the Bitcoin user population (including me) that will veto any such changes.

Phew, for a moment you had me worried, but with 90% following one side of a fork - then worries over.

da2ce7, please consider that nearly everyone on this forum has bitcoin's interests at heart. That it why thousands of posts debate the minutiae of any software change. Then consider how much progress there would be if 100% agreement was needed before any action took place...

But, for such a change, even 1% can veto it... That is what makes Bitcoin so great!  The economic problems caused by 1% forking makes it not worth for the 99% to implement the change.

I see the block size (and frequency) as much as economic rules as the total number of coin is.  I disagree with Satoshi that it is just something that we can 'change.'

I'm part of that sticky group of people that WILL NOT accept a larger block size.  I doesn't matter what other people say; or the reasons that they give.  Frankly, I would reject (with my full node, and SPV nodes) any non-bitcoin chain.  Any block breaking the 1mb/10min avg limit will not be a bitcoin for me.


However I am not worried.  I know that Bitcoin will be just fine with a 1mb block limit; as MarkM so eloquently put is, we need to get over having only one chain, but rarther think of having a ecosystem of hundreds of merge-mined chains that all fullfill different roles.


One of the reasons, (there are many), that I work on Open Transactions is that I believe that we need secure and cryptographically auditable off-chain transactions.  Making the need for more than 7tx/s on the Bitcoin block chain much (completely?) negated.

The best part is that I am in control of this problem.  Even if every other person moves to larger (or more frequent) blocks, I know my bitcoins are safe, and for-me bitcoin will keep-on working. (well other than the attack of a drastic lower hash-rate maybe)

So yes, I think that there is AT LEAST a key 10% of the Bitcoin user population (including me) that will veto any such changes.

152  Bitcoin / Development & Technical Discussion / Re: The MAX_BLOCK_SIZE fork on: February 02, 2013, 01:46:32 PM

In 10-years, a modern smartphone/computer will be able to run the full processing node if the Max_Block_Size remains 1MB.  This is a clear economic benefit for Bitcoin: Decentralized Bitcoin verification.  In fact in a few years, virtually every computer will be able to process the entire blockchain without issue thus making Bitcoin extremely unique in the realm of payments.

What is the use of having portable devices act as full nodes if you can't (because of fees) use bitcoin for purchasing anything smaller than a house? As I see it, your argument is not valid. With 1MB blocksize limit, even if Bitcoin remains a relatively small niche currency, the limit will act as a hard constraint on the potential utility of the currency. Of course, once we start hitting the limit, it will hurt Bitcoin's public image so much that it's conceivable so many people will move away from Bitcoin that we get few more years of time to fix the issue.

Lets not get ahead of ourselves here.  I expect that we will have a multi-layered system the vast majority of the transactions being made off-chain.

Additionally; who is to say that one wouldn't want to verify their house transaction with a smart-phone.

People completely mis-judge the free-market.   If you have to use alt-chains because the fees are so high, well isn't that a success of bitcoin already!  By no stage has bitcoin failed then.

The argument for larger blocks is VALID for a proticol that isn't Bitcoin.  However it is a catch 22, for Bitcoin.  It only becomes a problem if Bitcoin is a success.  If Bitcoin is a success, by definition it isn't a problem.

154  Bitcoin / Development & Technical Discussion / Re: The MAX_BLOCK_SIZE fork on: February 01, 2013, 12:05:26 AM
Jeweller, thank you for your great questions, I’ll endeavour to answer them.

First I wish to point out that that I believe that a bitcoin-like protocol that has no block-size limit. Where the miners choose the ‘best block’ based upon two factors: block size and difficulty, would be still economically secure. I suggest miners would orphan blocks that are too-large (thus too-expensive to maintain). (The network would find some sort of equilibrium).

If I was to pull out the continuous issue here:
Max_Block_Size is both a network and economic issue.

Changing the max block size has real economic consequences that can be split into two areas:  Fees and Uses.

Fees:
While I don’t think that the network needs a low Max_Block_Size to remain secure, that shouldn’t be up to my own analysis.  People may have invested into Bitcoin because they believe the 1MB limit to be the value required to maintain a secure network.

We don't know if Bitcoin had a different limit if they would have invested in the first place OR NOT.

Uses:
In 10-years, a modern smartphone/computer will be able to run the full processing node if the Max_Block_Size remains 1MB.  This is a clear economic benefit for Bitcoin: Decentralized Bitcoin verification.  In fact in a few years, virtually every computer will be able to process the entire blockchain without issue thus making Bitcoin extremely unique in the realm of payments.

We don't know if Bitcoin had a different limit if they would have invested in the first place OR NOT.


So I believe that the Max_Block_Size is clearly a moral issue, more than a practical issue.  Just like the Maximum Bitcoins, or Generation Rates.




- refuse the change and go with a small-block client
- grudgingly accept it and upgrade to a big-block client
- give up on bitcoin all together?
Keep on using the smaller chain.  Although I could double spend my coins in the larger chain for my own benefit.


Saying you reject it on "moral" terms though makes me think you might not be willing to make that kind of pragmatic compromise.
Yes.

Perhaps a better question then I'd like to ask people here is: The year is 2015.  Every block is a megabyte.  Someone wrote a new big-block client fork, and people are switching.  What will you do?
If it is better for my purposes than Bitcoin I would move over.  However I believe that the network effect will be that bitcoin is always my first store of value.

Hello,

I'm from a YouTube channel in the UK called Truthloader. I've seen us mentioned in a couple of places on the forum but I'm basically here to tell people that tonight at 7PM GMT we have a live debate on our channel with Gavin Andresen, Birgitta Jonsdottir and other guests. I wanted to let people in the forum know that this event was happening so that they could come watch and get involved in the discussion.

The link (if I'm allowed to post this) is www.youtube.com/truthloader but hopefully if I escape newbie world before tonight I can post the direct live link in the forums prior to the debate.

Would be great to see everyone/anyone there!

Thanks,

Grace Cheesy

Cool I'll keep a lookout for it!

157  Bitcoin / Development & Technical Discussion / Re: The MAX_BLOCK_SIZE fork on: January 31, 2013, 08:47:48 AM
Without a sharp constraint on the maximum blocksize there is currently _no_ rational reason to believe that Bitcoin would be secure at all once the subsidy goes down.


This is a very interesting game-theory question.

I have done some preliminary analysis of the problem and have found that gmaxwell may not be correct on this assertion.  (I used to support the razing of the max block size limit; however I now reject it on moral ground.  The same moral grounds that I would reject any change of the number of coins; that it would make any past uses of the protocol under a false pretence)

Now I will try and explain why a bitcoin-like protocol could be secure without the max-block-size limit.

The core issue is the mixing up ‘cost-to-attack’ with ‘active hash rate,’ when in the long run they separate to be quite independent qualities.   While the vast majority of the miners income is from mining blocks for new bitcoin; there happens to be a very strong causation, this causation doesn’t need to hold.

The first thing that we can define is the ‘damage cost of double spends’ this cost can be modelled defined by the equation:
cost = time x value
time: real number between 0 and 1
A double spend a long time after a transaction, for a large amount is a very costly (up to the full cost of the tx).


In the free-market, in the long term, the market will sustain any fraud rate that is less than the cost of reducing it.  (aka, it is cheaper to buy insurance than to increase the difficulty of an attack).
I see no reason why a bitcoin-like protocol wouldn't be subjected to the same principles:  The network will spend the absolute minimum on maintaining its security. (Either via hashing or via insurance).

So what is the cheapest form of network security? Dynamic response to threats.
Bitcoin miners incur virtually no cost; unless they are actively mining.  Bitcoin insurance companies could amass huge collections of bitcoin miners and turn them on when it is cheaper for them to out-mine the double-spend than pay the insurance out.

The bitcoin network will look quite easy to attack; well until you try and attack it.
This will raise the COST TO ATTACK (that is a constant); while the COST TO DEFEND is at a minimum; only the minimum number of miners are turned on to defend the chain when it is attacked.
Otherwise a background mining operation will be run by bitcoin companies for ‘general network health.’
158  Bitcoin / Development & Technical Discussion / Re: The MAX_BLOCK_SIZE fork on: January 31, 2013, 07:55:37 AM
This has been discussed again and again.  This is a hard-limit in the protocol, changing it is as hard as changing the total number of coins... ie. virtually impossible.

Many people have invested into Bitcoin under the pretence that the hard-limits of the protocol do not change.

Even if a super-majority wanted the change.  A significant amount of people (myself included) will reject the chain.  Thus creating a fork.
