The "crypto" world can probably handle 1 MT Gox but not 2. If another hack on that scale happens your coins might be "safe" offline but valueless.

A second mtgox is just a matter of time. However what an exchange does is not the determining factor of value. People will just move their money in and out when they need to instead of using exchanges as "banks".

One of the side effects of masternodes is the incentive to pull money out of exchanges. It will therefore prevent fractional practices, reduce short-selling potential (when short-selling is activated) as well as allow DRK to be more stable in case of an MtGox scenario of a big altcoin exchange, compared to other altcoins (less DRKs stored for hacking, due to many DRKs being assigned to masternodes).

You're spreading FUD, plain and simple.

I asked you to show me where the FUD is.

Quote the FUD and show me.

I only stated facts.

Bitcoin=trustless (can't lose coins)
Darkcoin=trustless (can't lose coins)
XC=trusted (can lose coins - the dev of XC himself admits it... perhaps he is a FUDder)

Is this FUD?

No, it's reality.

These dark trolls are viruses, just infecting every thread. Alex, let it go man. You've tried making the same point for the last month. Just go back to your Dark thread. At least leave this thread uninfected.

+1 they pop up on all coins trying to spread FUD it is so annoying, massive insecurity with their own coin if you ask me...

Then they wonder why everyone laughs when DRK falls...

Spread FUD? Where is the FUD in what I wrote about trusted and trustless transactions?

FUD is when you say DRK can lose coins when it's trustless.

So you got it backwards.

Please continue your cinni thread (unless provoked to respond).

Why did you come here in the first place.

I quoted some correct and some erroneous information and set the record straight. What's so bad about it?

Thanks for the questions. It does seem like you're missing something. Although, it might not be your fault. The whitepaper is definitely out of date. We've done a lot of work at tweaking the trust model so that it can't be exploited. I'll try to explain how it works briefly, then hopefully if I get time I can revisit the whitepaper soon.

- Masternodes don't have any power over the transactions. They just coordinate the signing. All parties must sign in order for the transaction to be valid. So there's no way to cheat and take the money.
- Users submit collateral. At a later phase if a user doesn't provide the signature as agreed, the transaction will fail. Without colateral this could be done over and over bringing the system to a halt.
- Masternodes have the ability to take the collateral transaction if they wish, but it's paid to the bounty fund. So it doesn't benefit them, it just benefits the community. This removed the incentive to cheat and take the money.

There's no relying on pools at all anymore. Payments to masternodes are done with a voting system embedded into the blockchain. It would take 51% of the mining power to pay the wrong masternode, or another party (because the last few miners to solve blocks must agree on who should be paid)

Transaction currently require 3 parties to be created, so there's a short wait. There are no fake transactions to make that quicker, although this could be done. There's usually 5 or so transaction per 2.5 minutes, so the network should be able to function pretty efficiently under these requirements.

Hoping that helps . Thanks,

Evan


I bet XC dev is taking notes.

Apparently he was taking notes. XC has abandoned the "dynamic trust model" plan as DOA in their nodes and is planning on implementing multi-sigs.

I guess the next step is to announce plans for collateral as well. Anyone have a guess for the next step after that?

Naming the way of transaction as X(C)Send? Grin

XC is in the near DUMP or a Pump-n-Dump right now. They released their new wallet. Anyone know if it is better than ours??My feeling it's a scam coin. Thoughts, comments? thnx.

~darylluke.

its a scam and not worth of mention in Cinni thread Wink

would you want a hold a coin that can stolen/lost because of xnode?  its completely experimental, people should able to expect that when they send coins somewhere it ends up at their intended destination, not someplace else because of malfunction or a bad xnode stealing coins.

Its unacceptable for your coins to be at risk because of experimental features.  Imagine you sent anon 100k XC somewhere and a bad xnode hijacks and sends it to their own address.  Shocked


How do you know this? I have a friend online who is in it right now.It is like talking to a wall. He is in love with it, and pouring more BTC in as it's rising!! I can't provide any substantial proof to him. Can you help? thnx.

Btw, that coin is one of 4 I lost my ass on.In at 401,000, and finally sold back all at 122,000.Just would NOT stop dropping in price... Cry

~darylluke.

Its been brought up in their thread, same as for DRK, its something that sounds good but isnt really needed, and because its experimental, currently you are trusting xnode/darknodes not to steal your coins when you anonymously send them somewhere.  You can be sure that the bad guys will be working to find exploits in the xnode/darknode to steal coins why place trust in a feature that was never needed to begin with. Also exchanges would have enough information on 99% of their users to undermine the anonymity provided.  

Anyway this is a Cinni thread.  not to support pumps for other coins Wink

Bitcoin = trustless transactions where money can't be stolen when a transaction occurs. (uses signatures)

Darkcoin = trustless transactions where money can't be stolen when a transaction occurs. (uses signatures just as Bitcoin's coinjoin)

XC = trusted transactions where money is forwarded from node to node with the potential to steal money. It uses coin forwarding.

So you are correct in that xnodes can steal coins, but wrong on darknodes being able to steal coins. Darknodes don't receive or forward coins. They are trustless and only process the signing of transactions.
2609  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][XC][OFFICIAL] X11/PoS/Privacy on: June 16, 2014, 01:08:18 AM
Remember - this is a Beta release.

Are coins in danger with the beta release?

Bitcoin is still beta...so yes.  there is RISK.

Bitcoin? Roll Eyes

Can somebody make a script to test 100 or 1000 transactions and see what percentage of the money go to the destination? For example if 995 transactions go through, it's 99.5% reliability.

It would also be good to measure the impact of multipath in terms of bloat.

19th-20th We'll see the strength of the balls left in the Dark markets. Many weak hands already shaken out, will there be many more who panic or manipulatively sell due to the impending fork? Only time will tell.
The fork is a good thing, the price should go up. Especially afterwards if all goes well, which it should do this time. *crosses fingers* There's certainly been plenty of good testing talent thrown at it and the recent outlook is positive.

I think we'll avoid random forking this time as it has been tested extensively on testnet for ~20 days under various scenarios, with multiple bugs fixed.

From what I understand some minor bugs / non-gamestopping issues seem to remain though, which should be fixed in next forks (rc4/rc5+). After all it still remains a complex affair as it introduces a new layer of consensus that the BTC protocol wasn't designed to support.

The price before the prior fork was like 0.025 or something so it's already much lower right now - it can't get much cheaper. The primary buying force behind the coin seems to be on "cautious stand-by" after the fork issues, sweeping low-cost coins when the opportunity presents itself by panic sellers, cost averaging his position to lower levels and price-correcting the coin to preserve its high coinmarketcap position which, in itself, took the coin to another level in terms of media exposure, market acceptance etc. The "pumper" did a great job in how he used coinmarketcap to boost the coin.

At the same time, this same buyer probably initiated the XC pump as well as a diversification option. The volume and buying power were almost the same level and that was not by coincidence. With the info we had at the start XC seemed like a nice addition / a nice prospect but the dev took the wrong course with trusted transactions, effectively undoing what the Bitcoin protocol does (trustless transactions). It's kind of salvage operation there, investment wise.

It's interesting how so many "anonymous" coins have been presented so far (based on bitcoin-blockchain) and yet despite the credentials or ideas of the devs, which in some cases are marketed as better than DRK's, it's still a load of crap in terms of tech. Central mixers, exchange laundering (lol), coin-forwarding from wallet-to-wallet, I mean you can't make this stuff up. And half of them (or more) are scamcoins - with some even being criminal coins, like honorcoin which used people's credentials to rob them off their exchange accounts.

Anyway, let's see how it works out with the fork and move on with improving the "core business" part (anonymity).

Considering miners will start getting paid, it's a tuff choice.

Wait and make sure things work at the expensive of possibly paying 25% more?  

If you pay 25% more, you've lost the annual ROI (supposing a large number of nodes are operational).

2613  Bitcoin / Bitcoin Technical Support / Re: Change addresses: What was the motive of Satoshi? on: June 15, 2014, 06:54:41 AM

I don't "buy" that part - but I'm not necessarily implying you are "selling" it.

Please describe HOW your ideal system works, not just tell us what system you want. If you can't describe an alternative system, just accept what we have

There is no need to be defensive like I'm "challenging" the entire system. My money is on the system that we have, so... take that as a vote of confidence.

As for the ideal system - in the context of transactions - well, it would be more straightforward in the sense that I have 10 BTCs, I give you 7.3 BTCs and I'm left with 2.7 BTCs. Can I code a fork of Bitcoin and make it work? No because I haven't coded in like 15-20 years and thus I suck at it.

As for the ideal system - in a broader sense - I think it would have to be something that is both trustless and decentralized, yet doesn't suffer from the 51% vector. The only way that I can think of, to do that, is the AI route: A trustless solution in the form of a self-aware supra-human AI network taking care of the transactions instead of a "dumb" if-then-else network. The reliability would be higher in the sense that it would still be a computer algorithm in charge, but it would be free of the human politics and bias + it would eliminate the need for 51% miner consensus or 51% stake consensus.

But it wouldn't only take care of transactions, it would be like a personal banker, but at the same time an efficient network administrator that prevents DOS attacks and manages the network load + distributing the storage requirements of the network to its nodes + ensuring the anonymity and privacy of its users by autonomously taking decisions that break pattern recognition and analysis by other AI software. It would also need to have QC-resistance and forking self-awareness when parts of the network go down (the AI would be decentralized - so, say, if Syria went offline, the AI part of the network would understand that transactions with the outside world would be problematic and the other AI part of the network residing in the global fork would understand Syria is "cut-off").

Authentication on said network could probably be done with ways that are unavailable today, like the network "operator" (AI) directly interfacing with the user and checking him out for his face, voice characteristics etc - instead of using keys. Keys could co-exist but they would be optional for the most part as people would interact with the AI.

Human-machine integration could also allow for authentication by producing keys that are unique to the individual, through external devices attached to one's body or internal implants. That's the part I don't like, but by the time suprahuman AI is available, human-machine integration will be a reality anyway in some degree or the other.

Escrow capabilities would be easy for that type of network and the potential for running other type of services on it (due to the supra-human intelligence associated with its operation) would be significant.

Masternodes are the answer.

Decentralized mining is the only answer... Masternodes get their income from the miners (in a sense), they are not 20% of the real mining power.
2615  Bitcoin / Bitcoin Technical Support / Re: Change addresses: What was the motive of Satoshi? on: June 15, 2014, 05:50:52 AM
You are asking two different questions (and I'm not even sure if you realize it).  Some people are responding to one of those questions, and other people are responding to the other question.  This is creating confusion and miscommunications.  I suppose, we need to start by figuring out which question you are trying to understand.

Question 1.
Why does a transaction need to include an output specifically for sending the change from the transaction back into the wallet? This could also be phrased as "Why was the protocol designed to spend previously spent outputs in their entirety?"

The answer to this question is that it is the most efficient and reliable way that Satoshi could come up with to create a trustless distributed system.  If you have a better way, go ahead and suggest it, but you'll almost certainly find that it won't work without a centralized trusted source of authority.

I don't "buy" that part - but I'm not necessarily implying you are "selling" it. The fact that Bitcoin is trustless is related to the PoW that makes it possible for the algorithm to determine the validity of transactions through network consensus - not because it uses change addresses.

I haven't done extensive research on other types of blockchains (PoW / PoS) that are written from scratch - perhaps someone that has a greater familiarity with such blockchains can tell us whether they are emulating Bitcoin's choice or if it is unique in Bitcoin.

Quote
Question 2.
Why does the Bitcoin Core wallet choose to create a brand new address to send this change back to with every transaction sent, rather then sending to one of the existing "receiving addresses" in the wallet?

There are several answers to this question:
  • It slightly increases anonymity and privacy
  • It slightly increases security by maintaining 3 levels of cryptographic functions between the private key and the address
  • It allows a user to track where all the payments to their wallet came from, since they can give out a new receiving address for every transaction.

The first part seems slightly futile when you do a common spend and things get linked. But it is a slight increase, I agree.

The second part, IMO, can be a small factor or a large factor, depending the point of time. In other words: Has a QC been developed (whether the public knows it or not) at a specific time? If the answer is yes, then money are far better protected.

The third part would be ok in theory but it creates more confusion for the average user due to all those tiny amounts that end up being an entire list. A visual representation tool would be, IMO, better for that purpose.
2616  Alternate cryptocurrencies / Altcoin Discussion / Re: Why Poloniex Has Rejected SuperCoin on: June 15, 2014, 05:20:27 AM
As mentioned earlier, max coins mean nothing if the coin generation formula stops earlier. There is no magic way for the dev to create coins out of thin air and if it was a case of doing it with a hard fork, he could update the number of coins as well.

However, it is the right of an exchange to list whatever coins they want and not list those that look shady to them for whatever reason. It is also their right to say why they reject a coin - no matter if it "hurts" the market or not. If a coin is vulnerable to critique of this kind, perhaps it's not so good of a coin anyway.

I created a more detailed diagram of how the anonymous transactions could work.

"could" ?

Are the specifications public or is this speculation?
2618  Bitcoin / Bitcoin Technical Support / Re: Change addresses: What was the motive of Satoshi? on: June 14, 2014, 06:38:00 PM
Nice analogy. Thank you for your time answering this... I still have a problem digesting the "why can't I simply cut the gold bar in half and pay with half of it and keep the rest" instead of remelting it / recasting it into new bars.

I think I understand why it happens as it happens (because obviously it was designed to be performed that way) but I still have questions on why it was designed that way when it could have been designed in a more straightforward manner. Maybe this is a multi-layered redundancy against a QC-attack-vector.

There are at least 2 "convenient" coincidences regarding quantum-computing protection...

1) the use of addresses as a hash of the public key (a quantum computer can't extrapolate the private key based on the hash of the public key, but it can do so with the public key itself - so as far as there is no spending, the money are safe from QC-attacks)

2) the use of change => destroying prior input and creating change. Thus the remains are not vulnerable to a QC attack to the public key (neither should the main output if the recipient follows best practices on how he uses his addresses).

The design doesn't seem arbitrary. The fact that Satoshi didn't go for a quantum-resistant algorithm for public/private keys is the only troubling aspect - unless we presume there wasn't an adequate solution at his time or the solutions he considered were probably deemed problematic in some other way that we don't know of. But he sure made his best to secure the system anyway despite the lack of QC-resistant algo.
2619  Bitcoin / Bitcoin Technical Support / Re: Change addresses: What was the motive of Satoshi? on: June 14, 2014, 05:33:51 PM
Understand that "coins" get split up and recombined all the time.

So your 100 received 0.001 BTC's can be sent out as 0.1 BTC (so the system doesn't *break down* because of everything turning into dust).

Key question: Are change addresses *needed* for this splitting and recombination? Can't they just be performed on a transaction basis?
2620  Bitcoin / Bitcoin Technical Support / Re: Change addresses: What was the motive of Satoshi? on: June 14, 2014, 05:25:09 PM
a) That's a very artificial limitation for an electronic payment system, wouldn't you agree?
Treating Bitcoin like an electronic payment system is a very artificial limitation for a distributed computer.

"What is needed is an electronic payment system based on cryptographic proof instead of trust,
allowing any two willing parties to transact directly with each other without the need for a trusted
third party.
"
