1  Economy / Services / Re: [Announce] Megareload alive and kicking - now even bitcoinier than ever! on: August 30, 2013, 05:31:59 PM
I don't think megaupload was the first to introduce incentive-based file sharing. it's just the first you've heard of Roll Eyes

Oh, I didn't mean to imply that megaupload were the "inventors" of sharing incentives, but their takedown has greatly marginalized this... noble practice.

I hoped Mega (the co.nz one) would rekindle it, but they chickened out and dropped the incentive model Sad

Now I'm watching megareload carefully.

If I may ask, could you go into more details in regards to to "js crypto" < "applets" <"plugins"  thing ?

In its infancy, cryptocat was a js-crypto thing.

This has caused quite heated discussions, among which was this article:
http://www.matasano.com/articles/javascript-cryptography/

Basically, js-crypto is unreliable. This caused cryptocat to move to plugin model.

Actually, plugins (when open-source) are more reliable than both applets and js-crypto.

JS crypto is both rather unreliable and hard to audit (I don't know if attacker has compromised your server and is sending out hostile javascript or something like that)

Applets are somewhat better (at least the damn things are signed), but even if they are open-sourced, I can't be totally certain that your signing keys and server haven't been compromised (causing a properly-signed yet malicious applet to be distributed).

However, I have to admit, that it is unlikely someone will go through the trouble of rooting your servers AND taking over your keys just to screw over a file locker (admittedly, a cheeky one but still)

Now, if I have installed an open source plugin, I can be certain that (assuming the plugin has no auto-update functionality) as long as the version I installed is "legit", there is no way to "switch it over" to something malicious from your side.
Browser plugins (if done right, mind you Smiley ) are thus the best way to get some semblance of a secure environment.


What is "Megareload"? Is it a megaupload clone site?

Well, they are more like "mega" and "megaupload" cross-breed, it seems.

What I like here is that the incentive business model (which Kim sadly dropped) is coming back. I adore incentive-based file sharing, it really rubs MAFIAA the wrong way Smiley

Folks, I'm glad you're alive.

I kinda wrote you off (but had a google alert configured to watch for megareload.se stuff anyway)

Glad the "incentive" thing is coming back (off course, I will only use it to earn bitcoins on legal files Wink uh-huh Smiley )

Things I think you need:

Folder-based uploading (not as in "upload this folder" but as in "upload all files in this folder"). This will make uploading split files much easier. Of course, then you will need some clever way to reuse password for a folder's content.
I mean, it's fine and dandy to encrypt them all with same pw, I reckon, but I guess entering the password for every-single-f[bleep]ing file a gazillion of times will get on people's nerves. I suggest you add some kind of "reuse password from previous download" functionality to the applet (you can store key material on user's box so as not to compromise your security model... or keep it in memory... whatever. You're the code people, not me Wink )

And you definitely need to significantly reduce storage time for free files that are unpopular (so as to force people to host totally legal Smiley popular files)

Also, you need open-source browser plugin a-la cryptocat.

I mean, sepukku is fine and dandy, but I think there's a whole body of thought that suggests that as far as crypto "reliability" goes it's "js crypto" < "applets" <"plugins"

Cryptocat does it the plugin way, you should too*

*I even promise not to have my BF excise advertising code out of the open-source plugin (then again, if boyfriends excising ads out of your plugin becomes an issue, you can make the plugin so that it only works for paid members)

5  Alternate cryptocurrencies / Altcoin Discussion / Re: [IDEA] What about mining on CPUs again? on: April 16, 2013, 02:38:51 PM
CPU mining friendly algos didn't play out as expected last time it was tried.

I've heard some IRC talks with people discussing whether it's even possible (consensus was an uncertain "maybe") but so far, no actual attempts.

I think it's just too early... Give it some time, someone will find a GPU/FPGA/ASIC hostile PoW Smiley

Well, so far it doesn't seem dead enough for my collection.

Bought a few anyway so that I have them when they finally die (if they do)
8  Alternate cryptocurrencies / Altcoin Discussion / Re: Litecoiners: Idea to make Litecoin importance skyrocket in Bitcoin ecosystem on: April 15, 2013, 11:41:22 PM

nobody is trying to give litecoin a sense of purpose. litecoin already has a purpose. many purposes actually.

1) slightly faster transactions (to accommodate the needs of...Huh... Huh )

2) an ex-CPU friendly - now GPU friendly - POW (to accommodate all the GPU miners who are about to be pushed out of business)

3) A general sense of hope for those who failed to get on the bitcoin train in time (to accommodate all those who failed to get on the bitcoin train in time)

4)  Huh

...

Well, I admit, technically, that makes 3, hence, "many"  Roll Eyes

and the reason why litecoin is "required" is simple: litecoin is still small/early enough to be adopting these kinds of things. It's much easier to make it happen in litecoin than to make it happen in bitcoin.

Which "these" "things" ?

being bitcoin's big and, as far as I can tell, not really necessary, backup tape ? That's some ambition, there Wink
9  Alternate cryptocurrencies / Altcoin Discussion / Re: Litecoiners: Idea to make Litecoin importance skyrocket in Bitcoin ecosystem on: April 15, 2013, 11:29:10 PM

Back on topic I think it would be beneficial to both Bitcoin and Litecoin.

So far, it is basically a rather contrived and complicated block backup mechanism so you could counteract and/or recover from a "bad" reorg.

I am not convinced it would benefit anyone.
10  Alternate cryptocurrencies / Altcoin Discussion / Re: Litecoiners: Idea to make Litecoin importance skyrocket in Bitcoin ecosystem on: April 15, 2013, 11:11:19 PM

IMHO Litecoin is doing just fine without this and it will continue to do just fine without this. Bitcoin needs this more than Litecoin needs this. If you can't see the usefulness in Litecoin at this point in its development, then just get to steppin'... we don't need you.  


Roll Eyes
 

a) it would be exceedingly hard to properly develop detection algorithms for "malicious reorg" detector

Reorg shows up in the debug output immediately in the client

It's absurdly easy to detect (just look for a chain that's been reliably mined for 6 blocks/1 h and then at 1 h the 7 block fork is detected --> report this to user via pop up)

The likelihood of two totally different chains size max of 6 MB (6 blocks) existing on the network at the same time and both being reported to a vast number of different nodes with neither group of nodes interacting is really, really unlikely

I am aware of those facts.

However, I believe you missed the part where I explicitly stated the qualifier "malicious".

Detecting a reorg is trivial. Determining whether it is an okay reorg or a "bad" reorg does not seem so.

Part C is where the process would break down and where litecoin would shine.  In March, the "heavy hitters" in IRC had the benefit of being able to reliably contact and influence the majority of the hash power in a short amount of time and persuade them to implement the desired solution, and they had the benefit of a ready-made solution (a version to roll back to) so that nobody needed to do anything objectionable.  Without both of those, the devs in IRC would have had far less power than they appeared to enjoy.

If a core feature of Litecoin were that mining nodes can accept operator(user) influence, those mining Litecoins get a decentralized pulpit from which to announce their collective opinion as to which fork of the Bitcoin chain is correct.  Even in the absence of that, Litecoin can implement automated validation rules with respect to the Bitcoin chain that would be too cumbersome for Bitcoin to adopt... example, Litecoin can be programmed to automatically refuse to endorse large Bitcoin reorgs without gaining explicit operator consent, which for a well-connected Litecoin node is typically a good policy.

I don't see why Litecoin is required here.

I mean, I realize that in this scenario, it is, essentially, a large backup tape.

But what exactly prevents BTC from, just, you know, keeping the reorged-away blocks for a little while longer and pleading the node operator to investigate "suspect" reorg when it occurs ?
Both solutions provide, essentially, the same functionality - block material is kept around for a while longer, so that human-op can decide which side of a fork he likes the best. But one requires mutual inter-operation between two cryptocurrency nets, while the other does not.

I, so far, fail to see the advantages to the "inter-operation" scenario beyond "let's give litecoin a sense of purpose" and "it would be a shame if GPU miners starve".
11  Alternate cryptocurrencies / Altcoin Discussion / Re: Buying Solidcoins on: April 15, 2013, 07:55:58 PM
I would give you mine just out of the goodness of my heart, but I am in the business of collecting dead coins, and my heart has recently run out of goodness.

So, no.
12  Alternate cryptocurrencies / Altcoin Discussion / Re: Litecoiners: Idea to make Litecoin importance skyrocket in Bitcoin ecosystem on: April 15, 2013, 07:53:54 PM
Excuse me if I understand something wrong... I'm a girl who dabbles in Java, and some of it might be over my head, but if this were to be implemented, a "hard 51" would go like this:

1) attacker uses Superior ASICs to mine a private BTC chain forked from some point long since past (probably so as to make a double-spend)

2) attacker publishes chain

3) an unspecified mechanism detects that there is, well, a so-called "malicious reorg", and BTC enters "hide yo coins, hide yo wife mode" and starts relying on backup data embedded in Litecoin's chain

It seems to me that

a) it would be exceedingly hard to properly develop detection algorithms for "malicious reorg" detector

b) if you succeed at a) you don't need no litecoin, you just keep around the blocks being reorged away until you are convinced that reorg was "not malicious".

c) you can, of course, just halt everything and have community "heavy hitters" decide in IRC which part of the reorg was "good" instead of doing it with "and then a miracle occurs" automagical "malicious reorg" detector, but as long as you don't discard the blocks involved (which does not require litecoin) you don't really need litecoin in this process.



So, TLDR:
I do see theoretical benefit to this general line of thinking (the "let's detect bad reorgs" line of thinking

I doubt that "malicious" reorg detector that would activate a "hide yo coins" mode when a real attack occurs is attainable

I could see a "dumb" detector being used to facilitate a "consensus intervention" on part of humans who have nontrivial power over the network (pool ops and devs).

I do not quite see why you need litecoin in any such scheme, beyond "let's give this altcoin some semblance of purpose"
13  Alternate cryptocurrencies / Altcoin Discussion / Re: PPCoin is NOT a decentralized cryptocurrency on: August 20, 2012, 07:37:31 PM
In all fairness, the authors of PPCoin admit it is currently not fully decentralized, but they wish to remove these "broadcasted checkpoints" in a future software update - it is used for bootstrapping the coin.

I can't say that I support the idea myself, but it doesn't smell like yet another SolidCoin to me, just leaves a bad taste.

It seems to me that in order for a coin to become soiledcoin, the coin's dev must pick a fight with an uber-hacker.

Do you know something about solidcoin that I do not ?
14  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [PPC] PPCoin Released! - First Long-Term Energy-Efficient Crypto-Currency on: August 19, 2012, 09:34:30 PM
You get to "mine" proof-of-stake by holding-and-spending coins in a manner that maximizes their age.

In principle, the idea is rather good.

In this implementation - not so sure    Grin
15  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANN] [PPC] PPCoin Beta Release Soon on: August 19, 2012, 11:49:51 AM
Yeah, Voices from Beyond the Veil are telling me that "continuous adjustment" is likely to end in tears.
16  Alternate cryptocurrencies / Altcoin Discussion / Re: DoS attacks on proof-of-stake on: August 19, 2012, 10:35:52 AM
Well, it had a rather poor proof-of-stake design, didn't it?

Any ideas why ?
18  Alternate cryptocurrencies / Altcoin Discussion / Re: Exchange based on Drupal modules on: August 18, 2012, 09:04:14 AM
No offense, but drupal is kinda heavy-duty for an exchange. Way too much overhead, unless you are very clever and skilled (at which point you hardly need drupal anymore)
19  Alternate cryptocurrencies / Altcoin Discussion / Re: DoS attacks on proof-of-stake on: August 18, 2012, 08:56:37 AM
There are different ways of designing proof-of-stake. Some of the designs do not require collecting large number of signatures. Our design will be made public by the coming Sunday so in due time we welcome the crypto-currency/Bitcoin community to examine our design.


Like I said in your other thread, it would be very nice of you to provide some kind of whitepaper, or even a mere "this is how our tech works" forum post.

Keeping people "intrigued" by your technological promise is an old and annoying marketing ploy.

Satoshi didn't start with "I have tech, but I won't show you it" publication.
