81  Bitcoin / Development & Technical Discussion / Re: btcd: a bitcoind alternative written in Go on: February 01, 2015, 12:37:12 AM

What is the status of the btcd wallet? We're quite happy with btcd as a node, but haven't gathered experience with btcd's wallet yet. Is it ready for production? Or, let's rephrase this: is someone using it for production purposes already?

There has been significant efforts to overhaul it for performance considerations recently. Within a month or two these optimizations should be merged to master, and wallet should be good to go for high throughput uses while consuming small amounts of system resources.

Previously smaller projects I have heard of using it in production.

Is there any differences between Monero and Darknote?
https://bitcointalk.org/index.php?topic=788916.0

Darknote has all things that Monero has. But monero does not have good price as Darknote.

DarkNote was previously DuckNote, and was basically instamined by the CN crew who realized that the BCN premine would never sell so they tried to make a new coin with a crazy distribution, then rebadge it and resell it. It's more or less the same as BCN.

Is Monero anonymous? Why what pros/cons compared to the Darkcoin tech?

Monero endeavours to make privacy in transactions mandatory for ALL transactions, small or large. Unlike privacy forks built on top of Bitcoin, there will soon be no way to opt out of privacy for Monero. Privacy in Monero requires absolutely no external factors that are points of failure like DarkCoin, e.g. masternodes. Instead, the privacy is baked in by cryptographic mechanisms that are provably sound mathematically.

Source? Why?

Does anyone have more info on XMR multisig? I only find requests for more info, but no definitive statements. Is anyone working on this at all, even on a theoretical level?

The last we heard of it:

Anybody familiar with OpenBazaar source code? How big of an effort do you think it would be to implement an XMR version of it?


ideally we'd need multisig. we're working on a version of it where no one can tell you're using multisig on the blockchain (the tx look the same as any other tx).

And

You mean the keys actually involved in the multi sig look the same as usual keys in a ring?

yup. as opposed to bitcoin, where they are stored in the multisig script (and so you can publicly tell all those who are involved). this will be offchain tech, granted we can get it working in the near future.

Simplest multisig scheme is described here: https://download.wpsoftware.net/bitcoin/wizardry/brs.pdf

No it doesn't. If it can't be used for illegal purposes then it's worthless. The point of decentralized crypto is to protect us from unjust laws and allow us to decide for ourselves what is right and what isn't. That's what freedom is all about.

Respectfully disagree. The Bitcoin blockchain is set up to easily allow someone who knows any addresses belonging to you to see who has given you money and where you are sending it. This is unacceptable from a privacy standpoint -- you would never accept a bank publishing all your transactions out in the clear. This is precisely why Monero exists, to be actual virtual cash.

And, in any case, if you believe that there is a 100% foolproof system for payments that you can use to break any law you'd like to that exists online... well, I would say you'll probably find out soon enough that that's a bad idea the hard way.

I agree with you insofar as my own moral foundation stands.  But a core value for me is freedom, and I would not assume to dictate to the users or markets how they use a cryptocurrency.

I rather see the neutral aspect of Monero being a digital cash for transactions which benefit from privacy.  It is a use case agnostic position.  

Certainly I can't control how anyone uses it, but I would not personally support such endeavours.
87  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency - 0.8.8.6 on: January 02, 2015, 08:54:58 PM
I don't understand you. Are you saying private money is okay but private marketplaces are not?

No; but I don't know what the net effect on virtual currencies in general will be if OpenBazaar really takes off for illicit trade, and I don't support the use of Monero to break laws. If governments wanted to shut down Monero tomorrow they could by computational attacks or by intimidation. Monero has bigger reasons for existing than to simply help you buy things online that are illegal.
88  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency - 0.8.8.6 on: January 02, 2015, 08:35:18 PM
I would love to help but I bought in at about the peak and hold so little it would be a drop in the bucket.

but this Freemarket Idea is certainly the way to go. It is even better if it could be integrated into the gui wallet to be released. This should be a consideration from inception so as to make integration seamless from the getgo.

I certainly wouldn't support this, and if the rest of the core team did I would probably leave the core team. Privacy is a design component of Monero there for numerous other reasons than to break laws, just as it is for Tor. OpenBazaar is an experiment on top of the Bitcoin protocol, and if it becomes the de facto world standard for illegal drug marketplaces I certainly wouldn't want such a thing intertwined with Monero on any level.

I don't condone or support the use of Monero for anything illicit or illegal in most countries... and, even if I did, I'm not sure I'd suggest using Monero for these purposes. The coin has not been well studied academically or even by multiple audit, so there may be numerous compromises in security that are yet to be discovered. Monero is intended to be used to afford privacy to transactions for the average consumer who doesn't want their neighbour peeking in on what they're purchasing, but for something where you have three letter agencies chasing you I'm really not sure.

You can already do this with BitMessage I believe -- it uses secp256k1 for signing and symmetric cipher key exchange.

I'm not usually interested in altcoins myself, but I can see how people can enjoy them. Most altcoin "investing" is a lot like gambling. I can see how trying to navigate and manipulate these tiny markets could be fun for a lot of people. These pump-and-dump altcoins aren't really competitors to Bitcoin: they're really a way of using your bitcoins to gamble. There are also a handful of technologically interesting altcoins like Monero, which I think are very useful for testing new ideas that might one day be incorporated into Bitcoin.

Even theymos finds Monero interesting Tongue

Totally deluding himself if he thinks that Bitcoin even has a chance of integrating CN tech. Tongue

Gmaxwell/Andytoshi are planning to implement it as a Bitcoin sidechain, although that would have to wait until sidechains in general exist. Right now they're in their infancy.

This Re-doubles my faith in Monero.

https://download.wpsoftware.net/bitcoin/wizardry/brs-arbitrary-output-sizes.txt

Unless I have read this incorrectly it is a simple addition to Cryptonote coins?

Not, not really, and whether or not it's a security improvement is questionable as it adds a new level of associative data to transactions (outputs are exponentially more likely to be smaller mixed in inputs than larger ones). At best you reduce bloat by a constant while introducing a property whose application to forensics is unknown.
93  Bitcoin / Development & Technical Discussion / Re: Decimal Places in Bitcoin? on: December 03, 2014, 05:15:58 PM
Everything value in the reference client is a 64 bit signed integer, and as such are Satoshis, not Bitcoins. There is no actual thing in the blockchain called a Bitcoin, it's just what we use to represent 1e8 Satoshis.

Why on earth it's signed is beyond me.

It's signed to make it easier to check for the results of a subtraction being less than zero. 

There are other ways to check the sanity of your operations... In monero, uint64 is used for coin units instead.

PoS system also intended to prevent 51% attacks
How?
By forcing the network attackers to read at least 51% of the whitepaper! :duh:
Mea culpa.

The whitepaper is a bit outdated, but I would personally refer you to the recent Proof of Activity paper by Iddo Bentov that details use of stake to further secure a blockchain again 51% PoW attacks.

Sorry w/r/t missive. Fluffypony is have difficulties connecting to the internet and is in another country. A person has been hired to handled missives in the future and soon they should continue to be on time.
97  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: November 10, 2014, 07:47:08 PM
Does this apply to making lightweight wallets as well? In that case I agree with your points, but still it would be nice to release the GUI asap, since itīs a great aspect of marketing.  

Yes. We're trying to get the framework in place to do SPV-style clients like Electrum, so Windows users won't have to sync the blockchain, etc.
98  Bitcoin / Mining speculation / Re: I have LOTS of idle servers, should I mine? on: November 10, 2014, 07:20:34 PM
We could use the hash rate on the Monero network.
99  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: November 10, 2014, 05:07:41 PM
You can't expect the raise of public usage unless you show people the official GUI. I don't know why is it so late, more than 6 months passed.

We're working on making the software more functional for payment processors and web wallets rather than concentrating on a GUI for the wallet that is attached to the daemon. The vast majority of Bitcoin users do not use full nodes anymore. In fact, only about 700 full nodes even exist on the Bitcoin network anymore.

https://getaddr.bitnodes.io/
http://bitcoinstatus.rowit.co.uk/

^ 7000.... you shocked me Wink

Yeah, missed a 0, but the listening hosts are lower (~3-4k).

And, with the current number of tx on the network per day, obviously we have more than this many people making transactions.

Btw, here's a second draft, a better worded and formatted one.
http://oleganza.com/blind-ecdsa-draft-v2.pdf
Great work Oleg, superb thing, here is your 4. Core protocol in Go language, w/ playground https://gist.github.com/kac-/a25e8410beb2d1514f2c.

Thanks, I will try to integrate secp256k1 into this if I get a chance.
