opticalcarrier, thank you for carrying the torch on the SSL issue.

As Marcus03 pointed out, "Technically, there is nothing that needs to be protected. The transaction data that is sent from clients to nodes, is the same data that is exchanged between nodes, which themselves do not uses SSL.
Or in other words, the beauty of the implementation lies in the fact that no trust is needed. It can't get any better. Putting SSL on top of it, for me just hides the beauty."

However, in the case of an NXT client operating from behind the firewall of a crypto (freedom) unfriendly nationstate, the mere fact that transactions are transmitted "in the clear" provides easy detection ability that a cryptocurrency transaction occurred. I know that if the primary goal was profit at the core operation level of the Nxt network, SSL would not be considered. The socio-political definitions of what is acceptable to particular jurisdictions is likely to change often in the coming years, and I think that providing maximum security and the ability to maintain plausible deniability to end users is a strategic advantage to Nxt.

The transaction may be secure by design and will succeed, but what good is that if the originator of the transaction runs afoul of misguided local crypto regulations? I don't know if this helps or not: https://www.cacert.org/

you make a really good point, and one that I had not even considered that I wish I had have included into my original proposal.  Much like BCNext's brainwallet provides plausible deniability, SSL would work alongside that for the same purpose.

And I do believe this will be temporary - maybe just for a year or 2 until SPs come along and provide the same functionality but on a basis where they are in the business to make $.  Then the SP will do their own cert.  But I am just running these VPSs to support NXT, not for profit, at least not anytime soon do I expect to be able to offer any kind of SP.

Another reason I want a domain wildcard cert is to be able to provide it to the wiki admin.  They REALLY NEED a valid SSL cert for their wiki, for login/editing purposes of the editors.  Consider that ideally, TOR is likely to be used by many people and if using tor, you REALLY NEED to be using SSL for pretty much everything you can - tor basically presents a MITM that could do attacks if you dont SSL your connection.

Hi Nxt community,

I am going to step out on a limb here a little. Let's say you have a safe in your house (Curve 25519 encryption algorithm) and do not have a lock on the front door to your house (HTTP). Even though you have a really awesome safe, you still don't really want everyone who wants to just wandering around your house.

All modern high security online facilities use a double lock security mechanism. The first lock is the HTTPS secured by a CA. The second lock(s) are the user passwords (names/passwords). Banks, schools, governments, etc. all use SSL connections. In the case of the need to remain anonymous, some nodes can be their own CA and issue their own certificates.

At the end of the day, when the rubber hits the road and the crypto becomes fiat; trusted (known) Nxt gateways that are in AML/KYC compliance will have HTTPS (SSL issued by a root CA). Would you enter your credit card number into a browser window requesting payment details that is NOT displaying the "Lock" icon? If your answer is YES to this question, then some serious study into network security is in order. All information transmitted over HTTP is the equivalent of talking on what used to be known as "the party line" to our grandparents. At least over HTTPS, only the NSA and GCHQ can peer into RSA; everyone else stays out of your house; for now.

Please be your own CA for now if that is what it takes for Nxt to "lock the front door". If anyone thinks I have my interpretation of network security all wrong, let me know. Otherwise, I think the competent and trusted network VPS operators need to take the steps required to make this a reality. Will the network run slower? Yes. Will there be more coding work required to the Nxt core? Yes. Will it cost money? Yes. Is it worth it? I think it is and so do at least a couple other Nxt community members.

Sincerely,
Brian Snyder

If infrastructure committee pays for half, I will authorized NXTcommunityfund to pay for the other half of the SSL cost. Maybe it is more of  marketing thing, but I think there is also technical merit to avoid plaintext transmissions, especially for NXTmixer and NXTcash usage.

James

P.S. If infrastructure committee doesnt want to pay anything, I will authorize NXTcommunityfund to pay for all of it. Just make sure that we are getting the right type of certificate. Ideally we can use this certificate for all the public nodes we are paying for?

The only way to make 1 cert work for every single node is for every node to be a host on a single domain.  Given that then it would be possible for the domain administrator to revoke a cert, thus causing DoS, then it would be possible for a single entity (admin of whatever domain) to revoke everything.  so this is really a bad ideaa, and this is why in my proposal I suggested that different VPS operators use different SSL certs than what I do.

The free alternative (and not really that bad of a method either) is for use VPS operators to issue our own CA cert and sign our host nodes with that.  But then the client software devs for the lite clients will have to include all of these CA certs into their software package.  This should be a good solution, just has the extra step of organizing and including the certs into the software packages.  (This step isnt required if we use publicly trusted CA certs to sign our server certs, which is what I had originally asked funds for.

@Evil-Knievel
Even if it is not the fatal flaw and you found something important like doctor evil did and CFB or Jean-Luc confirms it. I guarantee the nxt community will reward without
you even having to ask.

yep, even though hes an easily butthurt assclown that has problems relating with normal people (your near-demand for upfront payment with no proof whatsoever proves you have zero clue how societal norms work*), sure, we will pay him if he has uncovered something big.

*we will give you a pass if you are a non-native English-speaking person who mistakenly demanded $ up front w/o a shred of evidence/proof

That guy (Jürgen) is a dork, it´s evident by reading his previous forum posts for 2-3 minutes.

Whatever...

Okay, you convinced me!
I will make my discovery public very soon in a separate thread. I will also attach a proof of concept so you all can fix this issue quickly.
Strange, that it is so hard to talk to people from the "open source scene" ... they are (in many - not all - cases) somehow awkward.  Roll Eyes Or let me better say: Not compatible with normal dudes like me!


ok here is the part where I say: you are 100% completely full of shit, have zero clue WTF you are talking about, and your 'proof' will be laughed at, if you have the balls to release it, which im sure you have no balls.  You are a fucking moron.  Everyone took your statement and asked for more before counting you off, as a sane person should have.  We were very cordial up front before you let yourself get soo butthurt. Roll Eyes "normal" dudes like you?  please, give me a break.  for one "normal" dudes arent "trading 100K USD per day" on some crypto exchange.  fucking idiot.

Try to find that one first and people might take you more seriously then

No problem, if you think I am a clown then I will shut up about it completely from now on. But don't blame me when somebody else finds out one day.
It is so obvious that even the dumbest script kiddy would be able do do it.


great.  yet another butthurt prima donna.  dude, just do it already.

On Nodecoin/NXTcoin:

1) Who will buy them? It seems to me that it will follow the mine & dump path, so:
2) It will devalue NXT

PS: Ricky do you have skype? If yes PM me your ID please...

2 seems to contradict 1.  IMO, the more active nodecoin is, the more valuable NXT is
Don't get me wrong I try to understand the market reaction here..

Can you elaborate some more?

It will drive more transactions on the NXT main chain.  So the more things run on top of NXT like nodecoin, the more traffic NXT gets as a whole, and more transactions = more fees paid out.

All I would ask for is to fund my new Burberry Trenchcoat  Grin
Why I don't create them and sell them on BTER? Well, being a NXT holder myself I do not want prices to plunge  Grin

You first need to demonstrate its possible. If you do that part, people might reward after that. The last person who found a security bug received 10 BTC reward.



But it could be as well possible, that I spend a week of coding and get a 0.1 BTC reward  Wink There is so much other work to be done, which generates a larger income.

Also, If would go for it, this would inevitably result in a denial of service at some point.

ok, perform your trick, create 100 NXT, then get with CfB/JLP and point out the flaw and have them fix it.  Or just burn it all to the ground.  Do you recall how Dr Evil handled things for the flaw he discovered?

Let's call them Nxtcoins so that everybody will stop calling Nxt Nxtcoins

OUTSTANDING.  bravo.  all agreed?

That would be major dumb... As there isn't enough confusion right now ... ^^

i think its clever Cheesy

definitely clever as it really hits home the point of NXT and its capabilities in the first place.

I think since nodecoins are rewards for running nodes for nxt maybe we should come up with a way to reward nodecoins. Like some math guy come up with a proper reward
threshold in nxt for a certain amount of nodecoins. We can setup an automatic payout in nxt for nodecoins and fund it by donations or whatever. That way people will always
run nodes because they get free nodecoins which even if a little will be converted to nxt via a gateway or whatever as guaranteed reward.

No, it needs to be self-sustaining.

its too bad boobs arent self-sustaining.... I wish they were always perky but eventually they all droop
173  Alternate cryptocurrencies / Altcoin Discussion / Re: [NXT] NXTInfrastructure committee on: March 12, 2014, 01:32:32 PM
1.) Your rationale is that you would like to offer SSL specifly for thin client that do the transaction signing themselves and that do no longer send the secret phrase over HTTP. As such, these clients can work with trustless (no trust needed) NRS nodes. What is the additional benefit of SSL in this case? What data in the communication between client and server needs SSL protection?
Like I said before, its not required, and can work in a trustless environment; like I said, the benefit is that NXT presents a more polished product to the worl to use if the lite clients:
1. Prefer a group of high availability servers
2. Those servers use SSL.

I guess I wasnt clear before in my email that this is mainly for the aesthetics of NXT's presentation of the lite client architecture, and that I mainly wanted the group to consider these 2 points and whether or not they thought it was worthwhile to pursue.

2.) Regarding the price for a one-year domain-wide SSL certificate, could you explain what the additional benefit of paying 468 € would be, compared to e.g. 122 € for the "Comodo PremiumSSL Wildcard" product (https://www.namecheap.com/security/ssl-certificates/comodo.aspx).
It is high because it is from a vendor that allows anonymity for certs AND the cert is a wildcard cert that will work with all hosts on a domain (remember we have 12 VPSs here).  At least I believe it allows anonymity, I am still waiting on verification from ITITCH.  If I cannot maintain anonymity or if they wont let me use some kind of alias then I wont pursue this at all.  But I am not opposed on a product from any much less expensive provider if they offer anonymity.

If I were offering a product to the world where my goal was to profit, then privacy wouldnt be a big deal.

wait a tic...

Genesis block ID is 2680262203532249785, generated by account 1739068987193023818. Then 793 seconds later, account 10105875265190846103 which at the time had 170486123 as its balance, generated block 6556228577102711328.  But at that point its effectiveBalance was still 0. So how did anyone ever generate ANY blocks.  It seems there should have been a permanent catch-22 situation here.  Did the first clients simply not have the concept of effectiveBalance?

In getEffectiveBalance() it checks if the account creation was at block height 0, and if so it always returns the account's actual balance.


still?  so these 73 accounts can juggle their NXT around and immediately forge with all of it w/o waiting?

Nxt is being developed with payment privacy in mind.  I have not revealed details yet, but I can say that there is a special account in Nxt (recipient #0), later it will be used for advanced features (mixing, escrow, etc.)

well I just came across this from the original thread; is it obsolete?  BTW I found it on the wiki under whitepaper section....  Im very impressed with what you braintrust guys have put together so far.  Ive determined that Im finally going to spend some time and understand hit/target and the formula for when an account can forge...
177  Alternate cryptocurrencies / Altcoin Discussion / Re: [NXT] NXTInfrastructure committee on: March 12, 2014, 01:21:10 AM
I am already covering all other aspects of finance and operations for the network of VPSs that I run.  These have been funded by neer.g and by 1 other donor, I think it was pouncer but not sure.  In any event, these 12 VPSs are funded till almost end of year and Im not requesting funding for them at this point.  I also run an additional 13 VPSs that are paid for by other members where I simply manage them for the users.

You may have seen development talk regarding lite clients and local signing of transactions so as to be able to run a client that does not maintain a blockchain - these clients simply query public VPSs for account status and they also sign transactions and feed the transactions to the public VPSs to be broadcast to the network and forged into a block by whoever the next forger is.

My proposal is to use HTTPS/SSL encryption on the VPSs to provide a measure of authentication between the users and the VPS used when local signing is implemented (very soon now).  This will provide a layer of authentication security from the VPS to the user.

Note that this HTTPS/SSL is not actually required.  But IMO it is worth pursuing, and not just for me, but for other VPS operators that can provide a very high level of uptime of their servers for the purpose of serving these lite clients.  Another benefit of real live SSL is that it will just "look good" for NXT to be able to brag that there is a network of SSL hosts out there serving the lite clients.

So like I said - not required as these lite clients *could* just use wellKnownPeers and send signed transactions to them, but IMO the better way to provide reliable service to lite clients is to have the lite client software devs use, instead of random wellKnownPeers, instead use a list of very well maintained, high-available nodes, like the nxtcrypto.org ones, along with others VPS operators who demonstrate competence, and for the added layer of security, use HTTPS/SSL on all of them as more solid proof that the folks running the NXT network know what they are doing.

However, I agree with BCNext on creating a system that is capable of operating without trust.  So if you cannot find multiple VPS networks to be preferred by lite clients to serve these lite clients, and mine is the only one, then that scenario would not be able to operate w/o trust and I (and everyone else) would prefer that my VPS network simply not be preferred by the lite clients at all, and in that case, IMO there would be no need for SSL.

So thats pretty much it, Ive laid out the pros/cons, you guys let me know.

How can I request funding?  I would like to set up my network of public VPSs on SSL security to act as processors for lite clients that only sign transactions and submit them to public VPSs.  A wildcard cert for nxtcrypto.org domain to cover unlimited hosts is 468 euro

I'm waiting for an official sanctioned way by CFB on how to do local signing of transactions.

BCNext was delaying local signing to force ppl to install full nodes. I think we shouldn't wait longer and am going to implement prepareTransaction right after we launch Asset Exchange.

CfB, whats up with that?

Jean-Luc has almost finished this.

In that case today/tomorrow I will convert vps1 - vps12 on nxtcrypto.org to be HTTPS only and they will use the following CA
