And finally Bitcoin has no similarity with a democracy. None. There is no majority rule.

Of course there is it just happens to be 1 hash = 1 vote instead of the more common 1 person = 1 vote (or 1 white land owning citizen = 1 vote)

Really? And what does this "vote"(not really a vote) mean for me as a bitcoins owner? Nothing.

Everything.  If majority of hashing power agree that block reward is 50,000 BTC per block then it is. 
If the majority of hashing power implements a demurage on your wealth then it happens.
If the majority of the hashing power forces a 0.1 BTC min fee for valid tx then it is unavoidable.

So yes the votes by hashing power are very important.  Now for a Democracy to work the voters must be INFORMED and EDUCATED.  Most of the problems with modern Democracies can be boiled down to ignorance of the issues.  Life is "good enough" for most Americans in America.  Most voters don't feel the need to be informed, or question authority. Even bad legislation isn't bad enough to stir them to action.  Our govt has rigged it so most Americans don't pay income tax thus have no direct stake is how the govt wastes money.

The nice thing about voting by hashing power is the miners do HAVE a direct stake.  Their hashing power has a cost, the future economic value of that hashing power is a direct tangible benefit.  Most (maybe not all but most) miners tend to be relatively informed.  They are more likely to make decisions that enhance Bitcoin because it enhances their future economic value.

Quote
If I don't like what you're doing with your hashing I can sell my bitcoins the very next minute and put my wealth into another currency. I really don't see how that is possible in a democracy. In a democracy if you don't like how the majority votes, there's nothing you can do. You have to live under their rules or not live at all. Not so with Bitcoin.

Um ever heard of moving, or convincing the majority to change their mind, or violent overthrow of the govt?

I can exchange my Bitcoins for a currency I feel is better aligned with my interests.
I can move from my existing country to one where I feel the govt is better aligned with my interests.

I can work to change the protocol rules and convince a majority of miners to support those changes.
I can work to change the laws of my govt and convince a majority of voters to support those changes.

I can attack the Bitcoin network and setup a competing network.
I can attack my govt in an attempt to overthrow it and setup a new govt.

How should I interpret bitcoin days destroyed?  It seems if velocity is low then the number of days goes up.   If there are no transactions then this number is zero. 

If you spend 1 BTC which is 100 days old then it is 100 bitcoin days destroyed.   Some incorrectly dismiss this because moving some very old coins can result in a lot of days destroyed HOWEVER they are now 0 day coins.  Each individual move isn't important what is interesting is the aggregate daily # of coins destroyed and if that amount is rising or falling.

Hundreds of people have similar experiences and Papypal doesn't really care what you threaten them with.

The outcome was completely predictable.  If you hadn't been scammed with this sale you would have on some future sale. It was never going to end well.

Your were naive and foolish.  Now (hopefully) you know better.

Sites like that (dailytech is another example) are heavily biased by the authors.  If a site has a concentration of authors who have a snap judgement about Bitcoin then articles will be slanted that way.

10528  Bitcoin / Development & Technical Discussion / Re: One proposal for hindering antisocial blocks on: April 02, 2012, 02:23:10 PM
I am suggesting it, and some other people seem to have the same idea. And it can happen, that's ultimately up to the miners. Protocol changes have been done before. But that's really not the topic here, I just said that if that was to be done, the miners would not need that much freedom and the proposal discussed here would work even better.

While anything can happen you will never get 70% to 80% of miners to support it.  Notice I said 70% not 50.001%.  While technically you could fork the chain with any amount of support (even 1%) a 50% split would likely be the death of Bitcoin.  The original and modified forks would both exist, people would have coins in both forks and when sending coins they would need to specify which Bitcoin they were talking about.  Some exchanges/merchants might support "new Bitcoin" and some "old Bitcoin" and some would support both.  Users would have differing values in each chain and those supporting one side would see no value in the other resulting in massive selling. 

It would be beyond chaos, and the negative PR alone would be catastrophic.

It won't happen.  Even many miners who would support it in theory won't support it for the massive disruptions it would cause.  Discussion it is just pointless.
10529  Bitcoin / Development & Technical Discussion / Re: One proposal for hindering antisocial blocks on: April 02, 2012, 02:15:51 PM
I mean of course that the block reward is kept constant. (That we do take this protocol change in the future.)

Nobody (I guess you are?) is even suggesting block reward will be kept constant.  The fixed # of coins is a cornerstone of Bitcoin.  Changing that now (even if desirable) will never happen.
10530  Bitcoin / Development & Technical Discussion / Re: One proposal for hindering antisocial blocks on: April 02, 2012, 02:04:33 PM
I also think that keeping the block rewards constant for all eternity is beneficial in many ways and is going to be discussed more and more when we get near it's planned elimination, and if that is how it is done, the miners will not need that much freedom, they will just have to include all the transactions they see.

Ok this doesn't make any sense.  As block reward declines the need for miners to exclude unprofitable tx becomes even MORE not less important.  

To combine your the two underlined portions, so hypothetically when the block subsidy is 0 BTC miners should be required to include all tx.  Even if they are mostly 0 fee?  If miners must include all tx (even those w/ no fee) why would any user include a fee?  The simple answer is they won't and thus both block subsidy and fees will be roughly ~0.

So when block subsidy is 0 and fees are 0 how will the network remain secure?

All you need to do is cut the end off of the x1 slot. the x8 adapter will work in it

Realy?

I dont want to go damaging my mobo slots for nothing here Wink

It can be done.  The other option is to cut the "fingers" of your PCIex8 extender with a dremel tool so only the PCIex1 "fingers" remain. Wrap the cut portion in electrical tape.

A mistake there only ruins a $10 extender. Smiley
10532  Other / CPU/GPU Bitcoin mining hardware / Re: Graphics cards locking up - why so randomly? on: April 02, 2012, 01:51:40 PM
It's like speeding. It won't kill you every time, but it reduces the margin of error and increases your chance of crashing and dying.

Very good analogy.  

To the OP once you find that speed where cards are stable for hours but not days then you are close but still "speeding" a little too much.  Try dropping the clock 5-10 Mhz (remember every single GPU is different, there is no "standard" speed).  Cards will likely now be stable for 72 hours+.  At that point you need to decide if a reboot every 3 days is better/worse than dropping the cards another 5-10Mhz lower (where they may be stable for 30+ days).  

Another thing to look for (in cgminer) is HW errors.  Those are caused by the card returning garbage as "work completed".  It is a good sign the GPU is redlining and is right on the edge of stability.

It isn't black or white.  STABLE vs UNSTABLE.  It is a gradient (hypothetical numbers):
Crash instantly (0.0 ms)  - max speed
Crash in seconds - slightly lower
crash in minutes - slightly lower
crash in hours - slightly lower
crash in weeks - slightly lower
crash in months - slightly lower

By reducing the blockchain to the current unspent txOuts, he was able to reduce the total size from ~1GB at the time to 75MB, the majority of which was taken up by the scripts. Without needing scripts for standard tx, that could probably be cut in half, and if unspent txOuts were reduced to account balances it could probably be cut down to 1/4 that. The biggest change that would entail is that txIn would take the full value of the account rather than the full value of each referenced txOut, which would no longer be required for txIns. You would still have to store a few weeks of blockchain on top of that, but that's still < 100MB easily.

You don't see a problem with that? Currently a 51% attack "only" alloww the attacker to
* stop the network
* double spend his own coins (reverse txs he created)

If network is reduced to a flat ledger a 51% attack would allow the attacker to change balances of accounts he doesn't own which massively increases the economic value of 51% attack.  Even the potential is damaging.

Then again 75MB + 50MB per week (say 4 weeks of history retained) = 275 MB which last time I checked > 50MB claimed.  Also that was a back of the napkin estimate.  Someone actually did create a ledger and the size was 10% of full blockchain.  So that would be more like 200MB + 200MB for 4 weeks of history = 400 MB. 

The cost estimate for a pruned blockchain is ~500MB vs 2GB raw so you are saving very little.  Pruned block chain provides most of the space reduction with no loss of security.

Quote
AFAIK pruned merkle trees can only be used to verify your own balance, and not anyone else's. That is, you can't mine using only that, and you if you can't mine then you also can't verify a tx someone has sent to you.

Not correct but at least this time you correctly indicated it it your belief not fact.  

Pruned merkle tree allows verification of blocks, verification of your tx, verification of other users tx, and mining new blocks.  There is no functionality that is lost with the exception of tracing coin history beyond the oldest unspent output.

To verify tx (yours or anyone elses) you simply need to verify the prior outputs of the inputs in the tx to be verified.  By definition those would be included in a pruned blockchain.  Mining doesn't require anything beyond verifying txs other than access to prior blocks block header, the block height, and the ability to verifying work created by peers.

It might be a good idea to actually read the white paper.
10534  Bitcoin / Bitcoin Discussion / Re: What Central Exchanges Lack? on: April 02, 2012, 01:18:17 PM
I think fees is about the stupidest reason to avoid centralized exchanges.

EVERYTHING has cost.  Bitcoin itself has cost and fees pay that cost.

The things I dislike about centralized exchanges are:
* funds controlled by 3rd party (I would like to see an m of n type system where I have control of my BTC at all times)
* complete lack of accountability (MtGox deciding it is their job to be the Bitcoin Police)
* lack of transparency (does MtGox has $1 USD for $1 USD and 1 BTC for every 1 BTC in client accounts ? )

So far for more users those issues are dwarfed by the benefits of liquidity and narrow spreads.
10535  Bitcoin / Bitcoin Discussion / Re: "Bitcoins sent last 24 hours" completely useless stat? on: April 02, 2012, 01:04:50 PM
That isn't how bitcoin works.  Bitcoin can't spend part of an OUTPUT.  So all tx must include entire OUTPUT(s) not entire wallets.  So if you have 100 BTC in your wallet, you want to send 10 BTC, and the smallest output (or sum of outputs) which will result in no fee is 12 BTC then you send 12 (100), 10 to the destination and 2 back to a change address.

Still what makes calculating tx value difficulty is that it is never possible to know for sure which is the "payment".  In the example above you could be sending 10 (w/2 change) or sending 2 (w/ 10 change).

BlockChain.info attempts to make educated guesses to determine which was the intended tx.

Raw Volume (sum of outputs)
http://blockchain.info/charts/output-volume

Guesstimate on like tx volume (based on size and "roundness" of outputs tries to determine likely change and removes it from daily sum)
http://blockchain.info/charts/estimated-transaction-volume

The estimated tx volume is pretty steady at 100K to 200K per day.

Some people suggested that a node has to be "reliable" for people to connect to it. The node is running 24/7, but the internet connection reconnects every 24 hours. Maybe this is the reason.

If the IP address changes then other nodes will see you as a new 0 minute node.  Nodes identify other nodes based on IP address.  Theoretically that could be changed but I don't think it is a pressing concern.
10537  Bitcoin / Pools / Re: [360GH/s] p2pool: Decentralized, DoS-resistant, Hop-Proof pool on: April 02, 2012, 12:58:23 PM
Ahh.. ok no i have no static ip address and I don't even run 24/7... ;-)

static IP isn't necessary as long as your IP address is relatively stable.  Looking at the incoming peers chart it looks like >8 hours is where # of incoming peers rapidly increases.  For most users DHCP leases tend to be 14 days or longer (I have the same dynamic IP address as I did last year) so there is no need for a static IP address.

Keeping p2pool running is important.  nodes rank other nodes based on how long they have seen them.  If you are always seen as a very short lived and unstable node it is unlikely any node will ever voluntarily connect to you (as there are other better options available).  Nodes are oppertunistic (as they should be).   They seek out the best possible nodes.

Currently looking at the code it looks like longevity is the only factor is how "good" a node is.  That probably could be expanded to include things like latency, share notification (what % of shares did that node report), bad shares (nodes should verify shares before forwarding), version reported, etc.

One thing to keep in mind if that even if you don't mine 24/7 you can keep p2pool & bitcoind running 24/7 (both use minimal resources & bandwidth).

Some people suggested that a node has to be "reliable" for people to connect to it. The node is running 24/7, but the internet connection reconnects every 24 hours. Maybe this is the reason.

If the IP address changes then other nodes will see you as a new 0 minute node.  Nodes identify other nodes based on IP address.  Theoretically that could be changed but I don't think it is a pressing concern.  One way I could see that changing is by nodes identifying themselves by a public key.  This would allow nodes to retain information on other nodes even when IP address changes.

A simpler patch would be to have the node list include dns entries.  Then using dyndns one could always be the same url despite IP address changing.  Personally I like the public key method better (prevents the need for frequent dns lookups) but using dns is much simpler.

Looks like the people who where not upgraded got kicked from the network.

Well technically they are on an incompatible and minority fork.  That fork can continue to exist forever but hopefully they notice the 70%+ (from their point of view) drop in hashing power and take the time to actually upgrade their p2pool once a month or so.
10539  Other / CPU/GPU Bitcoin mining hardware / Re: Opps.. on: April 02, 2012, 12:49:36 PM
Yeah I am confused about what which slot you are looking to use?

PCIe x1 slot (which is not a "normal PCI slot")?

or

a normal PCI slot (which will require a different and significantly more expensive adapter than a PCIe x1)?

Haplo it is amazing that you can write so much and yet be consistently wrong.  I mean probability would indicate that a monkey randomly pressing keys would occasionally be right.

Haplo Myth:
the block chain could be 50MB.

Reality:
There are 1.8 million tx in the block chain thus 50MB/ 1.3 = ~27 bytes.  Entire tx stored in 27 bytes which can't be brute forced?  (cough cough) bullshit.

Haplo Myth:
pruned blockchain will prevent verification of tx by node without full blockchain

Reality:
Merkle tree was chosen because pruned blockchain will still allow tx verification

Haplo Myth:
There is no reason for the public address vs public key

Reality:
Addresses can be constructed from a public key but also can be constructed from other base types.  The use of an address allow similar processing regardless of the underlying structure.  It also provides cheksum, version, and protocol identification.  This greatly reduces the probability coins are sent to "nowhere".

Haplo Myth:
complex contracts take up more sense.

Reality:
p2sh allows massively complex scripts and contracts to take up no more space in blockchain that a "simple" tx.

Haplo how about you actually read the whitepaper, wikis, and code before incorrectly pointing out flaws.  
 
Haplo has no clue.
