The meshnet is intended to be a nice privacy tool with benefits comparable to tor, but lower latency correct?

The meshnet is intended to allow funding nodes via micropayments in skycoin to cover bandwidth costs correct? Doesn't this leave force all node operators to record detailed and published logs (on their personal block chains) describing all the transactions which inherently correspond to everyone who send data through their node? This seems like it would allow any third party to do traffic correlation attacks much like the ones on tor, except you don't need access to the connections. Even if they don't end up being publicly inspectable, logging everything seems like it might have some real issues (it can be requested by law enforcement, and takes up a lot of space)

The initial version is going to ship with centralized route finding server correct? This means if you want to connect to someone, you have to tell a third party about it, correct? It seems like this is not a Tor like privacy service until that's fixed. Is there reason to believe you will find a solution to this soon (or ever: its hard)?

How do you find a route to this trusted third party which will do route finding for you? I assume you will just special case it (don't use sender side route selection), but I'm curious if you have another design.


Yes. It is actually faster than TCP/IP. ISPs do "hot potato" routing. The latency should not be worse than TCP/IP and in theory can be faster.

The privacy guarantees are
- each node only knows the previous and next hop
- transmission between nodes is encrypted
- transmission is encrypted end-to-end
- your transmission is protected against man-in-middle attacks through the use of public keys for node endpoints (network addresses are public keys on the network)
- all encryption is deniable and ephemeral
- the protocol is designed to frustrate attempts at deep packet inspection to identify users running the protocol (no fixed ports, no known plaintext in wire format, fixed node connectivity for backbone and so on)

So it is like a very low latency TOR with micropayments for bandwidth.

- It is more secure and has higher privacy than HTTPS
- it is faster than TOR and scales but there are still attacks against it.
- the code is much simpler than TOR, so there is less room for backdoors or hidden vulnerabilities. There is only one external dependency in the whole implementation.
- If you need absolute security against timing channel attacks, you should use a mixing service or run Bitmessage on top of the darknet
- all low latency networks are subject to timing channel attacks


Route Servers :

Yes route servers are a weak link. For maximum privacy you should run your own internal route server.

However, if you do use a public route server, you are connected to it through several hops, so it cannot identify you. It would still be safer to run your own.

Handling of Micropayments for Bandwidth

The way micropayments are handled, is through a third party. The node connects to a "gateway", deposits a coin with the gateway to get a credit. The node can now generate pseudonymous 64 bit "addresses" with the gateway. The gateway does not know the identity of the connecting node. It only knows the previous hop the connection came through.

So if you establish twelve connections to the gateway, they look like twelve different users to the gateway. Eventually communication to the gateway will be over an asynchronous messaging channel.

The node forwarding the bandwidth, connects to the gateway also. The two nodes can now pay each other through the gateway, without the gateway knowing the identity of either of the two nodes. When a node has enough coins in credit (a full coin), it can generate a new Skycoin address and withdrawal the coin to that address. Gateways are only handling small amounts of coins

A gateway in the Skycoin protocol is any server that holds coins or account balances on behalf of 3rd parties. Gateways are deposit institutions and they have their own protocol and API.

Eventually,
- there will be multiple gateways and cross gateway coin transfers. These transactions occur in private and do not appear on the blockchain until you withdraw the coins from the gateway.
- messaging with gateway will occur through an asynchronous communication channel (each message steam will get a new pseudonymous identity)
- part of the gateway protocol is an OT implementation, which allows you to prove if a particular gateway is stealing coins. You sign each API call to the gateway, then gateway executes and signs the output. So there is a chain of linked signatures and transactions and the gateway cannot make coins disappear without being able to forge your signature. If you deposit coins somewhere and they disappear, you can publish your transaction log and then the owner of the accused node has to produce a log showing that you authorized the coins to go somewhere. If they cannot produce a signed API call, then it proves they are lying/dishonest.
- Eventually exchanges will operate under the gateway protocol

Your suggestion of having a public blockchain for the internal balances in the gateway is interesting. I think putting the internal transactions on a public personal block chain, could keep exchanges honest while still maintaining user privacy.

Wow hugh steps in the last months, but one question is open, what is your real intension for the next years?, wich position will reach and wihich products will you deliver after skycoin is realeased, have you thougt without the technical aspects  where you want to go? Have you thought about the steps after realease? The market now is much harder than month ago, you need a marketing Team and a good roadmap with your goals. You should not think only about the technical way, what i would like to say is,  even the best product with the best genius Development can fail if they are not prepared against pychological market movements (market members) .

You can see it all the way long on the NY Stockmarket, even smaler Companys with better Products as there compitioners can fail if they dont reach the consument. So please be prepared for the next steps.  thx.  I hope you ve a great succes.

I see you merged my pull request and responded to my questions. Thanks! I haven't gotten a chance to go through your responses in detail yet, but I have setup a wiki since you expressed interest. http://skycoin.wikidot.com/

Due to details of the terms of service, that site will have to be for informational, not promotional purposes ("any material that promotes financial products" violates the TOS for wikidot). Meaning skycoin promotional content will have to live somewhere else (we likely don't want it on a publicly editable wiki anyway).


I can quickly/easily add some discussion forums there, as well as start collecting FAQ content and links to various other resources.

Should I setup some discussion forums? (I don't want to try and suck your followers over to my forums unless you want me to and you will participate there)

There is no date yet.

I think Monero (XMR) is very interesting.

Way too complicated, but good job. Something simplier?





Like this. This is perfect. Except for the gradient background. White background, not too embellished or cluttered.

Can someone please dumb this down and explain the innovative features like I'm a 5 year old?



the old american way Cheesy

Whatever.

Just a few quick bullet points that any non-technical person can understand would be awesome. Thanks.

The original post is as basic as you can get. It's the massive explanations during this forum topic and the whitepapers that are technical and difficult for non-technical people to understand. Give the first post a good 20 mins and put an effort into understanding it. If you don't understand something, make a list and tell us how you interpreted it and if you're wrong, someone here will correct you and you'll learn from the experience.

Thanks.  I started going through thread and many of the technical posts were confusing to me.  So, I'm concentrating on the OP only for now.  At first perusal I got down to the CoinJoin part and I immediately got turned off. Please correct me right away if I'm wrong, but it seems like Skycoin will have a centralized anonymity feature?  Blast me and do whatever you have to do because I'm not trying to create FUD.  Just asking questions.  It all looks very interesting though.

My assumption regarding CoinJoin is its not centralized: its simply the idea that you can mix together a few transactions as one to make it unclear who is paying who. Doing this in a decentralized manner is nontrivial but possible and I assume what is intended here.

If you are interesting in another attempt to explain a few things, you can check out my brand new Skycoin FAQ on my new (unofficial) Skycoin wiki: http://skycoin.wikidot.com/faq

Eventually the content will likely be moved to some Aether based wiki, but for now the content can live there. Feel free to add questions and/or answers everyone. I make no guarantees about the quality of the content.
