Some very interesting discussions are going within the Supercoin thread since the source code release.
So Supercoin does actually have a very advanced p2p anon using multisig for its anti-cheat system.
Source code is now public so everyone can check it out for themselves. No need for assumptions.

It can be concluded that timerland is clearly in love with multisig.
Some questions that arise after reading all this though is that does XC have multisig? And what is multisig? Is it fud?

now that supercoin released their code, XC you can copy it over and claim real multisig

synechist, I am surprised at your low moral and ethics. You and your fud partners fud this thread and many others, only to show other people how stupid you are, it is disgusting the way you desperately argue and try to deny the facts.
Again, here are the facts:
XC does not have multisig tech [edit: under Timerland's definition] implemented. XC dev and its supporters did not even see an XC multisig address until some138 created 2 true XC multisig addresses for them.
They clearly mixed something else as the multig while they did not even realize it.
Again, this investigation is not on how good or bad XC is, or whether XC supported anonymous transfer. These subjects are not part of this investigation. The purpose of this investigation is simple and clear, it is stated clearly in the OP. And now the investigation is concluded with clear facts.
The fuds will never ever change the facts!

It's incredibly arrogant to call your terminological preference a "fact". Our preference differs. Deal with it. (In fact, terms are never "facts". They only describe facts. So you're on very shaky ground there.)
XC uses the term "multisig" to refer to transactions that require multiple parties to sign in order to be valid. This is a common scenario with any new technology: what to call it? It's new, and so there are no words for it. In this case we decided that our tech is best termed a multisig transaction that is distinct from a multisig address.
If you don't like our usage, well you'll just have to accept it anyway.
You don't get to decide. Because you're not God.
P.S. You don't know what FUD is do you? It stands for "fear, uncertainty and doubt". To have a differing opinion to yours is not to spread FUD. Perhaps it's you who needs to use terms correctly.
There are common terms used, which means something. Like multisig technology means what bitcoin implemented in the coin code and its many usage.
http://bitcoin.stackexchange.com/questions/3718/what-are-multi-signature-transactions
http://bitcoinmagazine.com/11108/multisig-future-bitcoin/
By using this common terms for something else, people will think either you are completely ignorance, or want to use it for your benefits in a cheating way. Either way it is not good. If you don't know it, it's probably ok. Now you are told the facts and you continue to depend it desperately, I don't see the points.

I appreciate some good discussions there. However, let us focus on our original questions. That is, does XC uses multisig technology? The answer is a clear no. They clearly took something else as the multisig, and they did not even see an XC multisig address before (which some138 first created 2 of them).
This said, I don't conclude that they don't have an anonymous system. XC may have a good anonymous system but this is not the investigation here. As I said before, multisig and anonymous system are two different things. Although multisig can be used to create an anonymous system like what Supercoin/mammothcoin did. Multisig can also be used for other things like open p2p marketplace created by Open Bazaar, in this case there's nothing to do with anonymous system. So let's be clear what is the problem we are investigating here, and don't boil the ocean by citing unrelated things. I am not here to judge the whole technologies used by XC. I merely try to understand their claim on the multisig, for that me and many others have got a clear answer and conclusion.
So investigation closed. No more fuds please, especially no need from people who understands nothing about the subject and multisig. Thank you all.

Yes, although Satoshi's white paper didn't have too much algebra...or did it? But I think you're right but I don't really have a grasp of the maths...so...hard for me to say much 
The day I see something comparable to this (excerpt from the Bitcoin whitepaper) in an altcoin whitepaper is the day I will do a little dance around the room;)
ok that seems a fair call...but maybe more will be apparent if and when XC is open?
Thanks again for your reply, its appreciated
Thanks again for your reply, its appreciated
Absolutely - once things are fully open and there's a whitepaper then there can be a discussion around the validity and correctness of the mathematics and cryptography presented in the whitepaper, as well as a discussion as to whether the code correctly adheres to the principles in the whitepaper.
August 17, 2014, 06:43:47 AM
This is a little unclear. You made a very clear and concise explanation of why you thought Supercoin had problems.
Now, however, it seems that you were not aware of how XC's trustless system works, and may have dismissed it prematurely.. Though I am happy to be corrected, but I can't see how you could have if you thought the previous poster meant "every node on the network".
I would be very interested to hear your thoughts on XC as you have a good understanding of these issues, and are fairly measured, and if Cloak and Super do indeed have problems then it may be that XC is the coin which could provide a better solution than Crypto Note coins.
Thanks in advance

Contextually the conversation was around trustless systems - my comment was meant to demonstrate that you can't have a trustless system unless "everyone" is or could be involved.

If you require an N-sized subset of the network to validate, then it means you are trusting that nobody in the subset group are malicious. It was quite late and was an unclear comment, unfortunately
Ok...but what can a malicious actor do in XC's system? I don't think they can do much as they are just signing transactions without the possibility of them stealing coins. Again I stand to be corrected.Quote
Incidentally, I keep coming back to a simple premise: we need to see valid mathematics behind things in order to understand them. These discussions wouldn't happen if whitepapers had more algebra and fewer "diagrams" (such as they are).

The knee-jerk reaction here seems to be "just look at the blockchain!" or similar, when looking at the blockchain created by a closed-source application won't reveal the size of the anonymity set. Bitcoin assumes that all (bar 1) connected peers are malicious (it can do nothing about complete isolation), and that should be the basis from which all good cryptography starts. A lot of the "solutions" I see lately start from the assumption that "every peer is basically ok/trustworthy and has no incentive to be malicious", which is patently wrong.

If EVERY node has to sign(meaning multiple signers) it is multi-sig. It is a trustless version, unlike supers where coins can be stolen.
lol - every node on the network? You understand that multi-sig is just an extension of pay-to-script-hash, right? When you understand P2SH we can talk.
No, not every node on the network.
For a transaction, an ad-hoc "network" is set up between participating nodes.
Most nodes participating will receive fragments of the transaction and sent them on.
Some nodes are redundant.
If a node fails to sign, then it gets booted out of the transaction, the ad-hoc network resyncs, and another node takes its place.
If all participating nodes sign, this sends the fragments onwards to other nodes.
As such, m-of-m signatures are required for each fragment to be sent, hence the term "multisig".
You're all welcome to dispute the applicability of the term, since multisig addresses aren't used. However regardless of what you call it, multiple signatures are required for each transaction.

BTW, this is Gavin Andersen's example on the multisig in Bitcoin. Supercoin/mammothcoin implemented exactly the multisig technology, same is done at OpenBazaar.
https://gist.github.com/gavinandresen/3966071
XC devs please learn and hope you will have a real multisig system implemented, not just a name.

Funny... do you still use AOL for your email as well. You are using bitcoin technology and open bazaar's rationale, both without anon.... therefore nodes can be more trusted, but they have to be trusted. XC offers trustless mixing where every node signs off and can't steal coins, if it doesn't sign, it resyncs and sends the transaction to another set. Highly likely most transactions will be very quick, but if there is an attempt to be a bad actor they are inhibited from gaining access to the coins. Your old technology multi sig allows bad actors/nodes to steal coins. THis has been know for a long time, with coins before yours that you stole to write your code. In fact you deleted a 500 post thread because it primarily discussed the inadequacies of this design.
ok since you attempted so many times, let me answer you: multisig tech is not anon, it can be used for anon system like what Supercoin/Mammothcoin did. There's no "old" multisig, there's only one, implemnted by Bitcoin and used by many.
You try to use regular tx and with some software side controls, this is completely different things. It is not multisig, it is whatever your private tech. Don't call it multisig because it is not. No wonder why Xc people never saw a XC multisig address starting with "4".
Please don't post garbage here. I think everything is very clear. If you have other facts as I asked, please post, otherwise don't waste our time.
If EVERY node has to sign(meaning multiple signers) it is multi-sig. It is a trustless version, unlike supers where coins can be stolen.
No, please do a google on multisig transactions, you see what it is. For example:
http://bitcoin.stackexchange.com/questions/3718/what-are-multi-signature-transactions
http://bitcoinmagazine.com/11108/multisig-future-bitcoin/
what you have is reg tx, anyone can post it in the network.
someone also posted a youtube on multisig with open bazaar implementation:
https://www.youtube.com/watch?v=oK85PCee3pU
multisig addresses can be created with RPC command such as addmultisigaddress in almost any client of the coin, including the XC client (that's how some138 created 2 multisig addresses for XC). multisig tx are those tx created on multisig address, where you have to have the required signature with private key in order to spend it (i.e. being accepted by the network). For normal raw tx, any one can post it in the network, no additional sigs required.
