Lol!  What a pile of garbage.  Apparently the only valid use-case is a set of different computers which use it to somehow open and unlock a door to an apartment.

322  Bitcoin / Bitcoin Discussion / Re: I found the Australian Bitcoin auction BTC address on: June 27, 2016, 07:33:30 AM
BTC on move now

Looks like at least 3 different winners to the auction since the following 2 addresses got 2000BTC (1 auction lot) and 4518 BTC (2 Auctions lots) https://blockchain.info/address/12aDD1xX9oP5V9PkEQm9G2H9vjrwW91u8i

https://blockchain.info/address/1L3h2xbDRmJDZooz9DFM4k43iVfvhJ1kog

This is good news. More than 1 winner means more likely chance to figure out who 1 winner was and that they might leak the price.

well guess the winner spending a lot of money while Australian govt just got it for free by seizing

Close.  People /claiming to be/ the Australian govt just got it for free by seizing.

My least favorite thing is Satoshi's Curse:

Never throw away any privkeys.

The pile grows and grows and you have to save them all!

OMG i know right those private keys man are worth so much you really gotta keep them forever lol it's great tho and my least favorite thing is the block confirmation times, they're just insanity now.
The halving coming up too its gonna be even slower.
The confirmation time is really a concern for everyone since it's getting slower and slower everyday. It's probably going to be a huge problem for companies/shops/facilities that accepts bitcoins as payment because the tx confirmation may not be as fast as with cash.

Nonsense.  Block confirmation will average 10 minutes no matter what miners do; it's called difficulty adjust.  Note that fiat currencies have NO public verifiable transactions which is equivalent to infinity for the confirmation time.  0conf still instant as are most off-chain solutions.

Bitcoin is first cryptocurrency than altcoin , so it doesn't matter if bitcoin without altcoin.
But if altcoin without bitcoin , this makes problem. Bitcoin just like base for other coin
that's right altcoin will not going to give affect to bitcoin but altcoin still count on bitcoin,every altcoin user always exchanging his altcoin to bitcoin at the end no matter how popular the altcoin is
Hey look you know what every user trades their valuables for, perhaps I can contract you to figure out what my girlfriend is spending the coin I gave her on. 
327  Bitcoin / Bitcoin Discussion / Re: Bitcoin IS basically DESTROYED on: June 24, 2016, 06:05:59 AM
From the beginning, this has always been a possibility: A banker who can effectively create unlimited fiat money can easily acquire all the mining infrastructure and control the network hash power (Of course he don't need to do so through one single entity, it will look like that many people control the mining infrastructure, but when a vote happens people will discover that over 90% of hash power is controlled by a few entity and can go against majority of people's will)

PoW method is vulnerable to large capital taking over. This is the nature of PoW, so some people have suggested to use a PoW+PoS hybrid model for the future mining, but without major hash power, how do you implement this change into the network? Why miners should give up their dominance power today? It seems only a fork or re-design of a new coin can start afresh

This is the most absurd argument ever.  People can aquire mining power, but they can't aquire coin?  Stake is easier to get ahold of than hashpower.  Just go over to the market and pick it up with your newly issued M1 tokens. 
328  Bitcoin / Development & Technical Discussion / Re: 'Vote with your bitcoins' system in Core on: June 23, 2016, 09:42:26 PM

Yes, the first one is just swapping coins, the second on is bribery.

Well both are dishonest, at least the coin swapping one can be filtered out by my proposal of not letting outgoing TX.

As for bribing Charlie, I dont think that would work, why would Charlie sell his vote?

If i had 100,000 BTC why would I lease out that voting power when I can just use that power to vote for my benefit. It would make no sense.


Well why would Charlie swap his un-voted coin for my voted coin then?   

Quote

It's like if you had an army, and you would lease that army to your ally so that he can conquer an island. When you can just take the island yourself for yourself with your army.

It would make sense for smaller sums, but those guys dont have much voting power anyway.

If the 100,000 BTC i would have can give me enough power to influence the community, i would definitely not lease it out and use it my own.


Your assumption was that Charlie didn't care about the vote in question.  In this case Charlie wants to take the island so that isn't the case. 

To get further into it we need more specifics.  How about a specific example of a coin-vote you have in mind? 

329  Alternate cryptocurrencies / Altcoin Discussion / Re: John McAfee: Cryptocurrency is coming on: June 23, 2016, 09:37:47 PM

Don't you think that there are some people who knows (at least approximately) the total number of the printed money around the world (no mater if its dollars, euros or pounds)? I don't think we should discuss this more, because its unnecessary. I will repeat that I gave that number with the intention to show how insignificant digital money currently are, and it will take many years (if "some people" allow it, which I doubt) to be considered even a little threat to the banks/governments.

No, it's not possible the know that.  It's not possible to know how many printing presses there are, or how many bills come from even a single one of them.  It's not possible to know how many people are sitting with palates of benjies in their garage.  Fiat is not public currency, these numbers are in no way verifiable. 

Banks and governments are made of people, and people are free to use public currencies.  There is no "threat" about it.

Yes, but the total wealth of the Earth (by some sources) is over $200 trillion.

Notice the total absurdity of this statement by those some sources.  For one there is no mention of M0 vs. M1 vs. higher   For two there is no way any of these levels of money supply could be verified, as the unit is "$".  For three, the unit of "$" is unbounded, issuers gonna issue, nobody can stop them.  For four, the unit "$" is without physical definition - there is no way to verify one has a "$" other than to pass it off to another idiot.  It's absurd to even think of it as a unit of wealth, let alone to assign a finite number to it or to claim you know some total number of "wealth of Earth".    

I was talking about the money in possesion of the people and banks, but I'm not going to argue about that. I just tried to point to the fact that cryptocurrencies are still a very tiny part of the "world's wealth".

The only things that come to mind for me as possible measures of the world's wealth are:

1) Biodiversity  (number of unique species)

2) Biomass (mass of living things, arable land)

If you want to talk about the world's exchange commodities, it's easy to say how many BTC or LTC the world has.

We check that the UTXO or set of UTXOs are confirmed on the blockchain when you submit the vote and sum them to the weight of your vote, we check the vote is a corresponding proper signature of the english voting statement, then we check that each UTXO is not an output of a previously used UTXO, then we increment the tally.  Not really that complex. 



You still dont understand the fungiblility problem.

Jonny has 1 Bitcoin = 1 BTC voting power  he votes yes on Brexit = 50%

Eve has 1 Bitcoin = 1 BTC voting power she votes no on Brexit. = 50%



Eve is smart so she votes, then swaps her BTC with Charlie and Charlie is not interested to vote again. She got a new BTC she votes again.
She then swaps the BTC again with Jimmy, and again Jimmy wont vote again.

Now Eve has only 1 BTC the whole time but she has voted 3 times with fresh coin.

Therefore the vote will end in 75% NO and 25% YES, because Eve cheated. It can be prevented if Jimmy and Charlie votes too, but not all people will vote all the time, so this kind of cheat will be very frequent in your system.

Aha!  Thanks for sticking with me and my stubbornness RealBitcoin, I see what you are talking about now.

Indeed, there is the interesting question here of what happens to non-voting coin (Charlie, in your example) and how it can be leveraged by voters.    

Yes, in the coin-vote as I have outlined it Eve could perhaps (for a small fee always) exchange her coin for "fresh" coin, that is - coin which has not voted, thusly increasing her voting power.  

If you set up your vote so that transfers invalidate votes, one can also pay a fee to leverage non-voting coin.  Charlie can simply be paid a small fee (free money for Charlie as he doesn't care about the vote) to sign the voting statement.  If Charlie is willing to make the exchange (non-vote for voted coin), it's likely he will be willing to sign a statement for a small fee.    

I don't see a huge difference between these two.. and indeed the question of how to handle non-voting coin and it's accessibility to voters (buying voting power) is outstanding and deserves further discussion.  Thanks for making it clear here.  

I see a couple potential solutions.  One is that one could mark certain coin as "voting coin".  This is the colored coin solution, that many have used already.  Votes can only be made with these coins and their children and no others.  No more problem from "non-voting coin".  

It seems that requiring coin to not be transfered as you suggest mitigates the issue somewhat, depending on the vote itself and interest.  For example it also stops somebody buying votes with coin that has already voted, though this isn't really much of a difference.  

To come to further conclusions here it seems we need to consider what kind of votes this system is designed for.  At first I thought it would be ideal for coin related issues such as BIPs or forks.  Then I realized that these things are mostly decided economically and the parties involved might not want their power and desire to be public.  For something like voting for a company director, the colored coin solution seems appropriate.  For something like public policy or election of public official, I'm not sure how appropriate it is.  What do you think?  

Cheers --

There is not "forbidding" it's only that once you had a outgoing TX, your vote becomes invalid. You can vote again but but if you spend again then the TX is invalid again.

You dont need to check every time, the checking only happens after the timer runs out.

You should not have any outgoing TX during the voting process. If you cant handle locking your coin away for say 1 week, you can vote in the last hour before the timer runs out.

It is very simple and it makes 100% sure no cheating happens.

Well you're still voting with coin, so more power to you.   Smiley  

The way we implemented coin-vote.com, we are 100% sure no cheating happens - and users can spend their coin whenever they like, meanwhile there is no requirement to make an official "ending" of a vote, people could continue to send in votes as long as they want and the tally is ALWAYS accurate and verifiable.  Tallies will never decrease.

If you see some vulnerability is the system as i have described it, please do tell.  

We check that the UTXO or set of UTXOs are confirmed on the blockchain when you submit the vote and sum them to the weight of your vote, we check the vote is a corresponding proper signature of the english voting statement, then we check that each UTXO is not an output of a previously used UTXO, then we increment the tally.  Not really that complex.

335  Bitcoin / Development & Technical Discussion / Re: 'Vote with your bitcoins' system in Core on: June 22, 2016, 11:10:52 PM

Yes. Specifically, voting is done not with an address but with an unspent output (but you can also choose to vote with every unspent output associated with an address).  When a new voting signature is submitted, we must go through every current vote and check the output tree from each to make sure the new vote is not on that output tree.  Typically the output tree is of length zero.  If somebody votes and then immediate sends this coin to a mixer, it would be longer.  However the query is still fast and unbreakable.     

Hold on a second I`m not sure we are on the same page. It's not the person that votes, but the coin. So it doesnt matter who owns which coin.

If you have 100 addresses, each having 1 btc, you can vote 100 times, but only 1 time with each address.

So 1 coin can only be counted once.

Now I`m not sure how you do that because if you allow a person to still send out money from that address, it will be difficult, because then he will just swap the coins with somebody else that didnt voted.

So you have address A with 2 bitcoin, you vote with 1 bitcoin, and keep 1 bitcoin. Then you swap the 1 bitcoin that voted with a  stranger, offchain, and vote again. Then swap again ,and vote again...

That would be silly.



So it's not the person that votes, not even the coin, but rather the address (and it's full balance) is voting. Also you still have to forbit outgoing TX from that address until the voting is over.



If you have 100 bitcoin but only you want to vote with 50, and use the other 50 for your personal spending, then you just send the voting 50 to another address and wont be moved until voting is over.



Yeah, I think we are on the same page.  I would refer to it as 1 satoshi 1 vote, rather than one bitcoin one vote, but that's a minor quibble.  Just as bitcoin is uncounterfeitable and verifiable, votes are uncounterfeitable and verifiable.  You can't double spend, you can't double vote.  Yes, you're right that there is no need to tie any other forms of identity to this.      

One thing people often don't realize about bitcoin is that the ledger is not a collection of balances held at addresses.  It is a collection of unspent outputs (UTXOs).  In other words, you might say "I have 50k satoshi at address 1aaabc..".  However on the chain what we see is some number of unspent outputs all credited to 1aaabc which total 50k sat.  When spending the 50k sat you need to pick from which unspent outputs they come from (this is handled automatically or manually).

The reason that a proper coin-vote system needs to recognize this fact is that otherwise an attacker could vote, after which sending dust to other addresses with large holdings, thus making it look like future votes from those other large addresses are tainted and should be rejected as potential double-votes.  While you can thusly "taint" an address, it is impossible to thusly taint a UTXO.  

A proper coin-vote thus enables a voter to vote with all the UTXO associated with an address, or with specific UTXOs, to avoid such an attack.  

There is no need to forbid outgoing TX from an address, though if you were lazy and wanted to run a vote that way - yes it would also work to prevent the taint-attack (apart from the disincentive to voters who should rightly be allowed to spend their coin).  It would also make it kind of difficult to keep a running tally of the vote, seeing as you need to often check whether any coin has left an address used for voting (and then invalidate the vote).  This will wind up being a lot more database queries than proper checking of votes when they are submitted.  








 
336  Bitcoin / Development & Technical Discussion / Re: 'Vote with your bitcoins' system in Core on: June 22, 2016, 09:42:43 PM

Not at all.  The time is of order N*(db query time) where N is the number of votes cast so far.  For every incoming vote, you simply check the address for taint from every existing vote.  This is not an "analysis" it is a straightforward database query and is nearly instant.  

For an example of a taint query on the blockchain see https://blockchain.info/taint/1dice6GV5Rz2iaifPvX7RMjfhaNPC8SXH

This is spelled out in my paper.  Did you read it?  

Our solution allows the user to spend the coin immediately, i.e. voting carries NO COST apart from the work of signing the statement and submitting it.  Don't you think that is better?  


What if the two addresses had contact before, can the taint analysis have a timeframe?,


Yes. Specifically, voting is done not with an address but with an unspent output (but you can also choose to vote with every unspent output associated with an address).  When a new voting signature is submitted, we must go through every current vote and check the output tree from each to make sure the new vote is not on that output tree.  Typically the output tree is of length zero.  If somebody votes and then immediate sends this coin to a mixer, it would be longer.  However the query is still fast and unbreakable.     

Quote

Also you have to test each voter against  the entire voting pool, and to conserve resources, let's just assume that the testing only happens after the voting ended.

So you have to test each address against all other, and if they had any taint in that specific timeperiod, then remove both of them from the eligible voters . When it's filtered out, then the remaining votes can be counted.


Why would we do that?  Each vote is tested when it arrives, and before being added to the current running tally displayed.  It's important that everything is transparent and can be checked by anyone by looking at the record.  

Thanks for your replies and interest in verifiably fair votes using bitcoin!  Smiley

I don't think the dollar, or any of the main currencies is going to crash this year, and for the world economy to collapse, you need the dollar to collapse, or at least the euro. I wonder if the euro collapses it would be enough, or the dollar is a must.

Anyway, the dollar will go on, because people accept it, even if it's fake as hell, as long as people accept it, things will go on the way they are.

I agree. As long as people accept it, it won't collapse as they still needing it.

The dollar will never collapse.  A single dollar will always buy several ounces of silver, it will always buy 10 bitcoins, it will always buy a good suit of clothes just like it used to. 
338  Bitcoin / Development & Technical Discussion / Re: 'Vote with your bitcoins' system in Core on: June 22, 2016, 08:15:14 PM

Nope!  Actually it is easy to confirm that no incoming vote signature corresponds to an output of existing coin-vote signatures.  The concept is sometimes referred to as "taint"..  any vote which is a signature corresponding to coin tainted by earlier coin-vote signatures is thrown out.  

There is no need to send coin or hold coin when voting.  Simply sign a statement with a key that holds coin (which isn't been linked to previous votes). 
Yea and you want to analyze all addresses and all addresses corespondingto all addresses.

That is just way too hard and requires supercomputers, my proposition is easy to implement, and it only requires people to give up using their coins for say 1 week.

If they really want to vote, such small sacrifice is not a big deal.

Huh 

Not at all.  The time is of order N*(db query time) where N is the number of votes cast so far.  For every incoming vote, you simply check the address for taint from every existing vote.  This is not an "analysis" it is a straightforward database query and is nearly instant.

339  Alternate cryptocurrencies / Altcoin Discussion / Re: Andreas M. Antonopoulos is "bullish on Ethereum" on: June 22, 2016, 08:05:58 PM

Incorrect. The point is that no matter what proof-of-work algorithm an altcoin employs, those who are protecting Bitcoin will rent enough mining hash rate to fuck your coin forever. They only have to rent it for a short period of time, and your difficulty will be so high that it will never produce a block again. And all the money in the chain will be unspendable for a very, very, very long time.

The "attacker" has the resources to do that to any proof-of-work altcoin which doesn't have the level of hashrate of Bitcoin.

Of course the altcoin can then manually reset the difficulty lower using a fork, but then the attacker can repeat again. It will quickly become clear that the altcoin is fucked.

If Monero starts to approach $1 billion market cap (or perhaps much less if the liquidity is very high, which it is for Monero), this attacker will destroy Monero and profit by shorting.

Dude you need to read tardlema a little longer before reposting the derpage here.  (I've been reading for years as you can tell by my fluent orcish).  

Otherwise, go ahead and rent some SHA256 asics and attack litecoin and monero with them.  I'll wait.

Hmm, i guess I didn't make my point clear, sorry.  My point was that your previously linked article (why there are no such thing as cryptocurrenciies)  assumed that hashpower is fungible across altcoin networks when in fact it isn't.  I only listed the coins as examples of coins secured with different hash functions, which are not mineable with SHA256 hardware.

There are always one currency on top of all but i dont think we can have only one currency. as we all know dollar and euro are the most used global currencies. while bitcoin is growing and became important as well, maybe in the future its worth can be as fiat.

Nice collection of false statements.  Care to estimate for us the number of people currently holding  人民币 in their pockets?  I just bought a few thousands of those fiat notes yesterday.  There is never "one currency on top of all".  People trade using whatever they like and negotiate the terms of their trade, as they always will.
