I'm not against bigger blocks. I simply disagree with the urgency suggested by some of their proponents as well as the current proposed implementations (especially the very dangerous XT fork)

The truth is that there's nothing dangerous in the XT fork, and the "smallblockers" are fully aware of this.

Either there will be a clear voting majority behind the push to bigger blocks, or there won't even be a fork. No fork will begin until 75% of the hashing power will start supporting it. In that case it will be crystal clear which fork can claim itself being Bitcoin, and which instead will end up as an altcoin.

This chart brings up a very good point.  Like you point out, in such a scenario, the miner can only earn a profit if he can include a sufficient number of fee-paying TXs in his block.  But what happens if the miner before him cleaned out the mempool?  It seems the rational miner will stop hashing1 entirely until enough new transactions have built up to push his block into the "profitable" zone in your graph (the zone where the supply curve is below the demand curve).  


Maybe I'm missing something, please correct me if I'm wrong.

In the event of an empty mempool (and with a 0 btc subsidy), for a miner to obtain a profit would be necesary to wait until enough new fee paying transactions enter into the mempool, otherwise keep mining at a loss.

Isn't this the same as saying

"In order for a transaction to be added to the blockchain, a sufficient fee must be provided"

I’d like to share a research paper I’ve recently completed titled “A Transaction Fee Market Exists Without a Block Size Limit.”  I formalizes the ideas from Cypherdoc, Adrian-X, thezerg, Rocks, ZB, Justus Ranvier, Solex, Melbustus, Majamalu and many others here.   In addition to presenting some useful charts such as the cost to produce large spam blocks, I think the paper convincingly demonstrates that due to the orphaning cost, a block size limit is not necessary to ensure a functioning fee market. 

Just finished reading it. Well done.

"Extracting?"  What an interesting word choice.   Roll Eyes

You make it sound like I put Satoshi's quote through some kind of violent mechanical processing, instead of the commonplace practice of editing for clarity and brevity.  But we all understand your goal here is to impute and exaggerate my intellectual dishonesty, in order to distract from the larger issue of why Team Gavinista is losing the Bitcoin Civil War.

The BitDNS discussion was not germane and thus excluded.  A link to the full text of the primary source was provided.

WRT my choice of word, guess what ? English is not my native language. Are you going to pick on me for this ?

But you know what ? I think that I like the image you are referring to. It conveys exactly the idea of what you are doing with that quote: you squash and grind its content, keeping only what you are interested in and discarding what you can't use.

WRT the "Bitcoin Civil War", keep on dreaming. If you think that "you" will be able to stop people from running the code they think will suit their needs, be my guest

Now its Frap.doc's turn to get rekt:

Piling every proof-of-work quorum system in the world into one dataset doesn't scale.

Bitcoin users might get increasingly tyrannical about limiting the size of the chain so it's easy for lots of users and small devices.


 Cheesy

You should keep in mind this while posting.

Maybe then you would take a full quote of a post, instead of just extracting a part out of its context in order to prove your point.

BitDNS users might be completely liberal about adding any large data features since relatively few domain registrars are needed, while Bitcoin users might get increasingly tyrannical about limiting the size of the chain so it's easy for lots of users and small devices.

But I guess that intellectual honesty has never been your goal here

I like the wind of subsidy in early tx's sails analogy.  But the recent appearance of "cosmic background spam" makes it outdated.

The problem is that sailboats are expensive to construct and operate, while Bitcoin tx are not.
[...]

Yes, they're not expensive, especially the spam ones. And guess why is that so ? Because there's no room for those transactions in a 1MB block, and  whoever is sending them can just resend them over and over again without actually spending a dime on them.

You are never going to get human consensus on an unlimited block size to the point where it isn't controversial. Just isn't going to happen.

The good news is that Bitcoin is not software.   It is a protocol  Smiley.   Of course you have to get people to agree to use your fork but that is another thing entirely.  Errr, consensus?

The problem is that currently Bitcoin (the protocol) is conflated with Bitcoin Core (the software). Until this state of things changes we are de facto running a centralized system, with veto power in the hands of a few selected ones. And this is what bothers me the most.

And now icebreaker is quoting a guy who's only contribution is a failed OS architecture, probably typing it from his incredibly successful linux android or windows monolithic kernel.  And yes I tried minix.  It crashed after a few hours.

And to add irony on top the argument actually adds ammo to block size increase crowd because lightning or sidechains will be an ESSENTIAL part of a 1MB chain.  There won't be any value to users if BTC is running if lightning or SC fails because there isn't space on the chain for users.

I'm guessing ice is still in school regurgitating here the garbage his professors (who likely never worked on a million+ LOC project in their lives) feed him.



Whoah, that's a bit harsh. I wouldn't agree on saying minix is Tanenbaun only contribution, there's so much more from him, despite being proven "wrong" on the specific monolithic/microkernel debate.

Apart from that, I agree with you on SC and LN (currently mostly vaporware) being an essential part of a 1MB chain in order to make it valuable.

I received one of these at the beginning of this week, I put it at work and this is what it's giving me atm:

I had a spare cpu cooling fan, I decided to give it a try putting it above the stick heatsink. Without the fan the stick was mining at an average of 3.7Gh/s, with a WU of about 23.0/m - it really gets hot Smiley

Just to share it, I'm having fun with it - it's my first miner after all  Cheesy

Why would the cost to a particular node depend on the number of nodes?

lol, do we have single centralized server ?

We don't.
But why should a single node owner pay for the storage used by every other node in the network, instead of bearing just its share ?
Because that's what it looks you're implying...




Whole network must upgrade. So spammer spend $1200 but bitcoin network 10x more on upgrade,

On the other hand:
Spammer spends 0 (no fees) while whole network spends K for bandwidth

Edit: I agree in full with Peter R and what his table reports.

12  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: July 21, 2014, 03:44:15 PM

I send the USD to the exchange in any way it's available to me, preferably with the cheapest one.
It could be one of these: ACH for Coinbase; Plain wire transfer (most of the exchanges)
Or even these: Astropay (Bitstamp); SEPA (Bitstamp, Kraken, and so on); ...
Thank you!  The answer did not have to be that detailed; the important point is that  turning USD into bitcoin requires a bank transfer (BT) of some sort. (Out of curiosity, are there exchanges that accept credit card?).

Well, strictly speaking, actually no, in order to obtain a bitcoin it doesn't require a BT, it's just the exchange part that requires it. Since you asked specifically for it I thought it could be useful to recap some of the available methods. Still, there are other ways to obtain bitcoins that don't involve a BT.

Just to name a few: localbitcoin (peer to peer exchange), ATM (Robocoin/Lamassu), mining (as unfeasible or expensive it may seem, it's still a valid method), donations (remember the "Hi mom, send bitcoin here" sign a few months ago?), or even salary (yes, there are employers who offer this opportunity to their employees).

As per your question, I'm not aware of exchanges accepting credit cards. Too much fraud risk, generally speaking (Oh, the irony).

Quote
[...]
So, that would explain why the price does not rise on such "good news": not because of "damn sheep" and "stupid weak hands", but because those news are irrelevant to most people -- except  for Coinbase and BitPay, and for the bitcoiners who wish to unload some old cheap coins.

Questionable assertion. Anyone could benefit from a discount offered in BTC prices at the present time, even while currently possessing 0 BTC.
 
If the company A ("Dell") offers the possibility to either

1) Purchase an item at full USD price or
2) Purchase an item with a x % discount if priced through BTC

I'd say that if the discount is greater than the expenses for the BTC conversion you end up paying a lower price, whether you have "cheap" BTC or not.

13  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: July 20, 2014, 09:55:33 AM

Yes you called the question stupid, and no you did not understand it. If "you pay USD go USD to BTC to buy", as the poster suggested, how do you send USD to Coinbase/exchange/Bitpay/whatever?

How about this:

I send the USD to the exchange in any way it's available to me, preferably with the cheapest one.

It could one of these:
ACH for Coinbase
Plain wire transfer (most of the exchanges)

Or even these:
Astropay (Bitstamp).
SEPA (Bitstamp, Kraken, and so on)
...

The point is, even if there are middle-man fees with all these methods, you will end up with BTC, which in turn gives you more purchasing power (due to discount, offers, etc) than you would have if you used USD directly.

I liked to see how much swap I got on a position. This would get complicated if it was paid daily and therefore set to 0. Not keen on having to log this daily.


I second this. Can you at least maintain the total accumulated swap cost visible in the same place it is now, just for reference ?
15  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: July 14, 2014, 02:35:49 PM

The leverage will vary depending on the type of collateral.

While this is true I would wager that the vast majority of users are using BTC as collateral and not USD so will most likely apply to most.

Agreed.

I think that overall this will be a positive development for bfx. It will help reduce the risk of the platform and address some of the concerns regarding the current amount of swaps.

16  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: July 14, 2014, 02:06:38 PM
Bitfinex has reduced their margin leverage from 2.5X to 1.5X, effective July 21st.   Officially, this is because the btc used as margin deposit is also volatile.

That's not entirely true.

This is what will happen starting from July 21st.


1st example

Current BTC price is 600 USD/BTC, and you have a leverage of 2.5:1

If you have 1 BTC, you can open a 1.5 max long or short BTCUSD position
If you have 600 USD, you can open a 2.5 max long or short BTCUSD position

Each dollar you add in your trading wallet will allow you to increase your tradable balance



The leverage will vary depending on the type of collateral.
17  Economy / Exchanges / Re: [OFFICIAL]Bitfinex.com first Bitcoin P2P lending platform for leverage trading on: July 13, 2014, 12:47:30 PM
I have a question too.

Assume I hold a LONG BTC position with the swap set to TERM.

Quote
Term: Swap interest will be capitalized in to position every night by automatically accessing swap offers to cover the required payment.

How will this work, in case the position is full leveraged but still above the margin call level,
i.e. the Tradable Balance is equal or less than 0  and the Margin Balance is above the Required Margin ?

Thank you

If we look at bitfinex swaps for a moment... USD-0.2016%-0.1272%-24,844,849.98 USD. Can someone gives an answer when those long will start to close if the price doesn't move up for a week? For sure we can't expect the price to go up much till the end of the auction... so when the rates on those longs will become to expensive?


Just a quick reply, I'm a long time lurker of this forum. In my opinion many people fails on estimating the swap rates on finex. It's true that the amount of open longs is really high, and the swap cost has been driven up to extortionary rates, but most of the swap has been taken at a much lower rate.

This is an actual example:

Swaps currently provided
Currency    N. of Swap Contracts (of 1 unit each)    Rate (% per day)    Opened at    Expire in    Actions
USD    2000.0    0.09%    21 May 10:44    2 days    Notify

As you can see this is a long term swap provided (granted, not my most successful swap contract...).
This has not even been placed as an autorenew. At that specific moment this was the highest request available, the FRR was even lower (about 0.07%, if I remember correctly).

My point is that in the 24M USD amount are included really low interest rates, and many of that longs have been opened at about 490/500. Again, I don't claim these are the most successful trades, but they're still there.

Hey,

This might be a stupid question,
but does this China's decision this morning
regarding not allowing Banks to participate in BitCoin Transactions
affect Bifinex in any way being that Bifinex Bank is in China : :

http://www.coindesk.com/price-crashes-china-outlaws-bitcoin-financial-institutions/

I don't think this is a stupid question, I am definitely interested in a reply from the Bitfinex staff.
I also have a question for the staff. This is an excerpt from a translation of the PBOC statement, please bear with me for possible errors:

Quote
Bitcoin websites should earnestly carry out their anti-money laundering duty, confirm the identities of their users, have them register using their real names, and register their name and ID card number.

Will this affect your current policy on verification ? I don't mind being verified if need be, but it's a hassle I would rather avoid if I am not strictly required to in order to use your platform.

Third party financial institution, which can guarantee large amount credit line or factoring? May be the same Slovenia bank knows some solution?

Slovenia has a systemic risk embedded, no way we'll put your money there.
 
Third party financial institutions taking risk on a bitcoin related business? You must be kidding me.....
If you find one you win 10 BTC, not only 1.
Wink

Thanks anyway

Giancarlo
Bitfinex Team

I'd bet you have already looked into this, but have you considered a bank from the same group of Bitstamp ?
I'm not sure about it, but I believe that you could obtain bank deposits/withdrawals in the same day even between banks in different countries, if they belong to the same group. This has been reported somewhere in this forum some time ago, so it must be taken with a grain of salt.

If this is indeed confirmed, you could try and find a country with a lower systemic risk than Slovenia.

I'm considering myself opening an UniCredit Group account in my country, should what I said above be confirmed and my needs require it.
