Hello, we deleted several posts quoting a particular vicious troll.

If you were deleted it was not because of the content of your messages, but because of the specific troll you quoted.

It looks like SDC went live with our solution for hashToEC.




They switched from creating a new generator, discussed here: https://bitcointalk.org/index.php?topic=1378922.msg14079014#msg14079014

What's this mean?

We are the leaders kids.


This is the heart of our algo, pushed publicly 9 days ago:

Code:
    for (j = 0; j < k; ++j)
    {
        if (j == 0)
            x = u;
        else
        {
            secp256k1_fe_set_int(&i, j);
            secp256k1_fe_add(&x, &i);
        }
        if (secp256k1_ge_set_xquad_var(&Q, &x))
        {
            success = 1;
            break;
        }
    }



This is shadowcash's pushed to their repo 3 days ago:

Code:
        while(!EC_POINT_set_compressed_coordinates_GFp(ecGrp, ptRet, bnTmp, 0, bnCtx) && count < 100)
        {
            count += 1;

            if (count == 100)
                return errorN(1, "%s: Failed to find a valid point for public key.", __func__);

            BN_add(bnTmp, bnTmp, bnOne);
        }


This is their commit after they read our critique of their method:

we need exchanger  Smiley

Yes we do.

We are doing everything we can to get on one.

In case anyone is wondering if we are working on anything, we are. But we won't have any updates until we get on an exchange.

We have approached every exchange. The community has to get involved. We only need to be on one for a few days to establish a price point, and then we will start to make development plans public and give updates. The reason is because we don't want to have a roadmap that will artificially raise the price and hurt distribution. We want to spend some time on a small exchange to let miners take reasonable profits while bringing more people into the community.

Right now, the logical place to focus is on yobit. Please submit requests there if you haven't already.

My problem is not solved
How to fix it? I download new wallet, but still the same






Just try twice. This happens to all Qts. You have to restart it once.
67  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [EC] ▲ Eclipse ▲ First Cryptographically Anon Based on BTC ▲ Mine Now! on: March 04, 2016, 08:31:22 AM
Sorry to say but a year ago, Sources of a release on github could be compiled without a fuss and without multiple tries immediately... Wink

That's because they were all pure clone coins. Pure clone coins build out of the box.

We have no argument with you, though. I'd say our mistake was that we launched something that is not a clone coin as if it were a clone coin, and that didn't leave much room for error.

But once built, you can't argue that this puppy isn't a great coin for mining, staking, and its intended functionality.


On another topic, what are people's thoughts on this "HTML5 wallet" that Eclipse presently uses? Seriously, I thought it would be cool but I find that I'm not so fond of it.

What does everyone think?

Could we get a block explorer that shows the current coin supply?

Yes. We are working on all this. We are still nailing down the following:

1. Finalize branding, logos, etc., pay the bounty
2. Add enough Website Content to satisfy exchanges
3. Block explorer (probably fairglu's) -- this much of the list will get us on yobit and/or bleutrade
4. We need to decide on where to host the Qt wallets so we can track downloads (not mediafire)
5. Finalize the medium-term development road map
6. Get the whitepaper finished (post bleutrade/yobit, pre bittrex)

It seems like a straightforward list, but we have multiple devs and we have to reach consensus about every little thing.

Once we finalize all decisions, we should proceed through the list pretty fast, although we will pace 4 & 5 to ensure we spend enough time at the smaller exchanges before we move to the larger.

sounds good but 3,4,5,6 are pretty much a parts of 2


We are going to go through the process in due time. First you get on small exchanges for price discovery and distribution. Then you go on big exchanges. There is no rush here. Miners can get out early at a smaller exchange with some good profit. And believers can hold for bigger exchanges or implementation of roadmap features.

We won't put the cart in front of the horse.

We are going to put some website content up within the day. For now, the community should start to try to help us get on yobit or bleutrade.

In the meantime, here is a block explorer with rich list: https://chainz.cryptoid.info/ec/

nice.  one step closer to exchanging.

well shit, one address has 44% of total supply....
This is either going to be a crazy pump or already a dead coin....
Doesn't help that they are staking constantly as well...  Lips sealed

85% of the supply is claimed, and one wallet has 44%. Who thought 2.1 million max in a couple weeks would be a good idea? Great concept, but hair-brained approach.


A couple of years ago, all coins were distributed like this and there would be 400 miners on a coin in 30 minutes. Nowadays, you can't get 4 miners before two days go by. I guess times have changed.

Hi Dev,

HiPoS Reward: 300 Corona, decreasing by 10/day to 20 Corona
Post-HiPoS Reward: 10 Corona

What are Corona's?

Eclipse has two currencies: coronas and eclipse. A corona the clear currency. Eclipse is the dark currency, protected by cryptographic ring signatures.

Somewhere in cyberspace you can read "A corona (Latin, 'crown') is an aura of plasma that surrounds the sun and other celestial bodies. The Sun's corona extends millions of kilometres into space and is most easily seen during a total solar eclipse, but it is also observable with a coronagraph".

In other words, it's the part you see. "Corona" or "Crown" or similar is used as the name of many currencies, referring of course to the crown of a monarch. The crown of a monarch is meant to represent halo in western cultures, which itself can be traced to representing the corona of the sun. And we come full circle with the etymology and symbolism.

Is there a minimum amount, at which staking becomes possible?Also, it seems that the wallet weight does not change?

There is a minimum amount, but you would probably never actually stake with it. You could stake with 1 EC.


On another topic, we have moved the downloads to bitbucket:

If possible I would like to see some sort of voting/proposal mechanism for EC like DNET has.
It encourages community participation and would require certain minimum investment to influence direction of EC.
If you insert a masternode system of some sort, you can split up PoS rewards (voting rights is good enough too).
Also I would like to see 10 EC PoS inflation decrease to <5 over time.

There isn't any reason to reduce the 10 EC inflation rate. Over time, the fixed reward will represent less and less inflation.

I don't anticipate anyone on the team embracing masternodes. We don't see a use for them unless someone can make a very compelling case.

It's not clear how a community is going to implement anything it votes for. How do you see that working?

Exchanges don't require a roadmap or whitepaper.  Is there more you think we should be doing?  We're more than happy to accept help if you feel this isn't suitable in the short term.

Why are you guys spamming the SDC thread and Slack?

I don't see any spamming in the thread... I posted the 'fix' to SDCs anonymity bug because it concerns SDC, does it not?
What I posted is very relevant to SDC. It's not like I was talking about rainbows and butterflies.

SDC looks to be converging on a reasonable fix, but not a recommended one.

Originally, they took the scalar hash then multiplied it by the private key and then used it for the scalar multiple of the group generator (two different types of "multiply" here but I didn't invent this convention). Math looks like

I = H(K_i)xG

That was the very wrong way.

Now they take an arbitrary point on the curve by hashing the time stamp, trying to map it to a point, then using that point as a generator. This takes advantage of the fact that all curve points on a prime field can be full generators. The new generator is G*

I = H(K_i)xG*

There is a relationship between G and G*, namely one is a multiple of the of the other:

G = aG*

But in this case G* is "unknown log", so G is protected by discrete log hardness.

In general, however, it is not good to try to use a generator to hash scalars to a curve. They already learned this lesson once.


The fact that $G$ = $aG^*$ is but a little lemma whose proof that I found in the margins of my notebook.

I will use the additive notation, since this is what is used for Elliptic Curves, but it's just a convention.  Multiplicative notation is just as fine.

Lemma *:  Let $K$ be a cyclic group of order $n$.  Let $G$ be a generator of $K$, i.e. $<G> = K$.  Then, $\forall H \in K \exists a \in \{0, \dots, n-1\}$ such that $aG = H$.

Proof:  Assume $K$ is a cyclic group of order $n$ and $G$ generates $K$ and let $H \in K$.  By definition of cyclic groups, since $G$ generates $K$, there exists an integer $a \in \{0, \dots, n-1\}$ such that $aG = H$.  -- see https://en.wikipedia.org/wiki/Cyclic_group .  
Q.E.D. of Lemma *.

Now, since the elliptic curve that is secp256k1 is a group whose order is a prime, then it is a cyclic group.  This is because all groups that have prime order are cyclic -- for a proof, see : http://planetmath.org/proofthateverygroupofprimeorderiscyclic.  For some clarification that secp256k1 has prime order, see : http://bitcoin.stackexchange.com/questions/38108/order-of-group-of-points-of-secp256k1 and the answer by Akater which references the documents defining standard curves, for instance SECG -- http://www.secg.org/sec2-v2.pdf -- to which secp256k1 belongs.

Therefore, by (*), $G = aG^*$ is true.

I'm a bit lost, are you saying that SDC testnet fix is valid?


That's not the topic of that math. The other dev is just clarifying mathematically where I asserted the relationship G = aG*, and showing how it is valid.

That was actually a response to a post on the SDC thread where someone without much math knowledge was questioning what I said.

You can't respond to them in their thread or you will get deleted.

So our other dev decided just to do it here. He proved the relationship holds for all group elements G* over a prime field because G is a generator for the group. Our other dev is a real precise mathy-type who doesn't let anything go in the way of math reasoning.

Oh, and to answer your question, I said "G is protected by discrete log hardness". So the exploit that de-anoned their chain in the first place is now protected by a cryptographically hard problem. However, I also observed that the way they are doing it (maybe to save CPU cycles) is not advisable in general. I can show a couple of reasons why.

Here's essentially where they pick their generator in their current plan:

Code:
uint256 hash = Hash(Params().pszTimestamp, Params().pszTimestamp + strlen(Params().pszTimestamp));

What's this do? It takes the hash of the same time stamp string used for the genesis hash and will use it to map to a generator.

Then this generator is used for every ring signature in the entire block chain.

Now, if, for some reason anyone ever solves a for

G = aG*

Then the whole system comes crashing down. Every signature will be deanoned. Period.

You may be thinking that the discrete log problem holds here and you would be right. But, on the most practical level it is a single point of failure. Of lesser potential issue is why did they pick that timestamp? There are zillions of seemingly obvious strings and numbers that could be used to seed the generator. Why not the name of the coin, why not "Satoshi Nakamora", why not "Alan Turing", etc. etc? Admittedly this second potential for nefarious intent is far-fetched, but it exists nonetheless, and is a valid cyptographic concern because it leaves some wiggle room that compromises the "rigidity" of the crypto system.

Our system has neither this single point of failure nor arbitrary parameter.

I'll further add that this seemingly simple solution used by shadowcash undoubtedly occurred to the creators of cryptonote. Why didn't the cryptonote devs use this solution of a generator with "unknown" log? Why would they not want to make their system save CPU cycles and further find the group point in constant time? Why did they use a curve where they could solve the root (or find a residue for the root they found)?

These are rhetorical questions, but very important to ask.

Hi all, we are hoping a pool operator will decide to add EC soon to increase the ability for everyone to mine more easily.

Please continue to check back.

You'd have a chance if your broken source on github would compile Smiley

Eclipse is the 12-year-old Indian kid's coin, every time. Broken source, every time. Abandoned before a pool, every time.

I should know, the few times I've bothered to mine I get about 75% of the coin supply before every other node leaves and the coin dies.

I am not a 12 year old Indian kid and we are working on it.  There have only been 105 blocks mined so please stop making assumptions.

OK, since this post I've monitored the thread and I'm convinced you aren't Niitassin the 12-year-old Indian kid who serially releases cryptocurrencies called Eclipse or Eclipsecoin and abandons them.

The "insert an image of an eclipse here" is the kind of jokey voicing I've come to recognize from his ANN threads. And he was talking about implementing the same library.

But he wasn't forking SDC to fix its broken anon and you are, so that's good. I'm mining. Best of luck.


Thanks for your support. We really didn't do our background research on the name "eclipse". None of us had heard of a coin called eclipse, so we thought it was a cool name that conveyed "hiding". It just turned out to be a strange coincidence, especially with the jokey voicing, as you say.

We hope to build a little steam and get some loose ends like a website, branding, etc., together so this looks like a real coin. Window dressing is the last thing we thought about. We spent all our time prior to launch just making sure we got the crypto right. You'll see that the part we fixed is technically correct according to the latest literature, taking into account best practices. That still can't be said for the fix that shadowcash has planned.

can't download Windows QT from Mediafire Huh
Please change this sh*t storage on something better
mega.nz as example
Good luck, dev!

Okay. We'll put it on something better. We are almost done building the mac wallet.


We still need to move from mediafire, but the Mac wallet is at http://www.mediafire.com/download/wa9i3b2pi8rprdh/Eclipse-Qt.dmg

We just finished building it. We'll move from mediafire soon.
