121  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][CLAM] CLAMS, Proof-Of-Chain, Proof-Of-Pearl, @Poloniex.com on: July 12, 2014, 08:54:57 PM
I'm trying to stake, but the client says the coins aren't "mature".

8 hours, right?

Minimum Stake Age: 8 Hours

Mine took longer than 8 hours. From what I could tell maybe twice as long. If it tells you your stake reward is in 20 minutes, wait 20 minutes and it might say 15.

Then again, I'm not a CLAMillionaire. So I don't know if that's the reason. But it appears the averages could be optimized.

8 hours is really just an estimate based on how long it takes to reach maturity. The block maturity is 500, so 510 (10 for confirmation) blocks after you put the Clams in your wallet the green light should come on and staking should begin. The block times have been slower then then should be which is why it would have taken more then 8 hours. 

Also, from my understanding the 'stake reward time' is just an estimation calculated from your weight and the network weight. It can be pretty inaccurate (from experience), especially with growing networks like Clam's

Does it matter if my wallet is locked or not? (I locked my litecoin wallet). Will I receive clams with a locked wallet?

Locked wallet won't create any issues.  Your wallet.dat will stay encrypted and as per usually it will ask for the password when you go to send

Dev can I claim in  BTC in Electrum wallet?

Im not a electrum expert but it seems like you should be able to use  dumpprivkeys( map(lambda x:x.get('address'), listunspent()) )  to get a list of private keys on the wallet with unspent outputs.

From then you just need to import them into the client. The Debug window->console   importprivkey     function will do that for you

Check out https://electrum.org/console.html for more details on dumping the keys

this kind of data is always interesting to look at but of course some people keep DGB across several wallets, as I do. Last time Jared posted about this I got the impression there were multiple holders of more than 10m DGB

Yeah, your not wrong (about the data). The new client also trys to enforce not reusing addresses now, which means best practice makes it impossible for a parser like this to associate an address to a wallet.  

Its accurate on a per address basis.

The data is interesting but useless if your looking for the biggest wallets. It can tell you broad things, like there are 200k addresses with unspent outputs (just a made up number), there have been a total of so and so addresses since the beginning of the chain, etc.   Interesting, useless data.  My favorite kind Smiley

Is there a way to see the the top wallet holders of DGB to see how the coins are being spread out?

YC

Yeah, i'm curious about that as well. I want to be be in the top 3.

I've used one of the open source block parsers (https://github.com/znort987/blockparser) which can find the unspent outputs for all the addresses on the chain.

I'll throw the DigiByte modified version in a repo so you can compile it yourself and check it out.  I'll includ my dump too, so you can just check the list if you want.

I haven't confirmed its accuracy yet but when I checked the balance on my address it was correct.

It will be a few hours, need to run out for a bit

I don't know much about economics, I'm more of a tech guy myself.. but I suspect because of the way clams were distributed the total clam distribution will trend with the total users. aka The more people that claim their Clams the more clams there will but the more demand there would be also which would possible lead to a constantly rare coin.

Should be very interesting to see this progress.
127  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][CLAM] CLAMS > Proof-Of-Chain > @AGX.io on: May 25, 2014, 10:34:06 AM
Amusing idea, but the OP needs to make clear how the coins are distributed.

~4CLAM are given for each unique txout, unique address, or by balance?  If it's by txout, then this is a HUGE scam... If it's by address, then this is a HUGE scam...  Why?  Because anyone who designed this coin and had half a brain would have split up a million Doge into a million wallets, and had 4 million clams...

---

When importing, the debug.log shows a LOT of exceptions being throw:
Code:
******* exception encountered *******
ERROR: CTransaction::CheckTransaction() : txout.nValue too high

******* exception encountered *******
ERROR: CTransaction::CheckTransaction() : txout.nValue negative

******* exception encountered *******

******* exception encountered *******
(This goes on for pages).  Something buggy happening during the import scans?

Did you run -salvagewallet during the first load? Otherwise your wallet.dat will hold tx information for invalid tx's, thus the "too high" and "negative" errors i suspect.

Also I was wondering about the dogecoin make a million address thing myself. While still costing a good amount in fee's, especially if you wanted to try to redeem those 1M 1 dogecoin addresses, you'd stand to gain more if things were to take off.  
 
If everything is correct I believe the majority of the address's must have came from the bitcoin blockchain. I say this because according to what Im seeing there are not enough addresses with positive values on the other chains. Keep in mind the block chains I'm parsing would not be in sync with the blockchains that the clam devs used so this is currently just a guestement at best.  

Ive been playing around with the one of the block chain parser and Bitcoin has currently over 2.7M addresses with balances above 0, which would be the majority of the ~3.1M Clams addresses distributed too. I don't claim to the accuracy of said parser I used but I checked a few of my addresses in the list and the balances were correct.  

If thats true, which intuition based on observation is suggesting is, that only leaves ~400k addresses between Litecoin and Dogecoin. I've yet to parse their blockchains but if the numbers on there chains are correct Litecoin and Dogecoin only add up to ~400k of the ~3.1M.

It would seem the majority of the coins went to Bitcoin holders.

I'm working on a script to test that, convert the address back to ripemd160 -> back to bitcoin and then see if it was a used address on blockchain.com

I'd be happy to provide the script for anyone interested, although I warn you, its in Go.

Edit: Clam Devs, the source used to create the original send would be very helpful as the current block-chains will be out of sync and not provide an accurate picture

Was just going through the git commits. I see the commits from after the fork from blackcoin and nothings looking worry some to me. I see there was some changes to base58 to support the keys with other identifiers, the rest seems pretty standard.

Built it in a fresh vm instance with no issues. Moved my coins to new wallets just to be extra safe and when I opened clams it seemed to be correct, there were clams there. 

Staked a block a few minutes ago with no problems also

Interesting idea! I considered something similar but got side tracked with other projects, I'll keep my eye on this one. 
129  Alternate cryptocurrencies / Announcements (Altcoins) / Re: trying solo on: May 12, 2014, 10:04:09 AM
the payouts have gotten so bad I'm taking 22 of my mhs and trying solo today.

block sizes are 168 and we will see what happens.

but pools only report block sizes of 158.1 - where do the rest of the coins go out of the block on the pools?

The block reward was never 168. 

Block 49, the last block of the premine the reward was 3236.

Block 50 the reward went to 159.39  (http://explorer.nautiluscoin.com/block/98c4bf0592d7413ff4ec9c2d61bf3b95ef8495e955764af1ac5169a63e28b328

Currently the reward is 157.7961.

Im still working on getting the new template working as its layout is quite boring at the moment.

It works though Smiley

How I can to compile the linux wallet. I perform qmake USE_UPNP=- and get next. What I am doing wrong? Help!

try qmake "USE_UPNP=1" or 0

The building process has changed some with the new client. Make sure your up to date with the git repository and run the following to compile.

Code:
./autogen.sh
./configure
make

The complete guide for building on linux can be found at https://github.com/digibyte/DigiByteProject/blob/master/doc/build-unix.md

"DigiShield" is spelled wrong in V2.9.1.0


Thanks for pointing it out

Spelling is not my strong suit, I'm sure there's one or two more spelling mistakes in there so if you see them let us know!.

We will have the updated client that fixes the ssl bug out later today. The URI payment protocol in the new client (2.9.0) is affected. I'm unaware of any web services for DigiByte that implements the payment protocol so risk should be very low. Once the new client is released if you were using 2.9.0 it would be best to send your DigiBytes to a completely new wallet and delete the old one. While this step isn't required I always err on the side of caution.

If your still using DigiByte 2.0.0 you should have no issues but coin control in the new client alone makes the update worth it.

One solution could be using a system similar to myriadcoin, we let all the algos in the coin and each of them has it's own difficulty. This way we could keep scrypt, and implement X11, and others also.

I've been looking into the myriadcoin solution since talk about switching algorithms was brought up. Something about how it balances the mining and allows ASIC and GPU's to live together is appealing. I had a few concerns about potential attacks but they addressed my largest concern even before I even had a chance to mention it by weighting the difficulties against each other. I have the code setup in a testnet integrated with the DigiByte code and haven't seen any issues yet. More testing is required but it looks promising.   

Changing over should not be taken lightly though as the code is only one aspect. With this approach we would need new pools for each algorithm, new block explorers etc. To a large extent it would be like a relaunch. It would also make the process of mining more complicated, which isn't necessarily bad but is against the general approach of DigiByte and our goal of bringing DigiByte to the other 99% of people who don't yet understand crypto.

I'm not saying we should switch as I'm still largely undecided, its a difficult problem. If we were to change I'm personally becoming a fan of the approach that myriadcoin has taken with there algo design (at least on paper). To me it seems like a balanced approach and could be tweaked for digibyte and accommodate other algos if we so desired.  

Quote
Scypt, SHA256D, Qubit, Skein or Groestl

How it works
Each proof of work algorithm has its own independent difficulty.
Any algorithm can find the next block.
All the algorithms use the same difficulty adjustment method.
On average, each algorithm has the same chance of finding the next block.
Each algorithm aims for a block generation time of 2.5 minutes.
Over the five algorithms, a block should be found on average every 30 seconds.

It would require some changes to infrastructure where we would need pools for each algorithm and depending on which algo you mined you would use a different mining program.

It needs more research but its an interesting idea and worth exploring
136  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][RND] RandomCoin -Random Dif every hour- [NO Premine][Exchange ready] on: March 27, 2014, 01:44:33 AM
I'm not quite sure I get how a random difficulty can work and would love an explanation as I'm a fan of the concept and have considered it myself before.  

If each client is randomly generating their own difficulty on the hour whoever is lucky enough to generate the lowest diff required has the most chance to find the block as they require the least work, locking in the lowest diff a large portion of the time.

I'm also interested in how you can go back and validate blocks. When you go to verify a block with a 'random' difficulty change how does it find this random number again with certainty? When a block is processed it compares its PoW included in the block to what it would generate in getnextworkrequired. have you removed this PoW check for the blocks with diff changes?


Edit: taking it a step further there would be nothing keeping someone from modifying their client to always pick 1 diff on those changes. Where anything between 1-20 has to be valid for that block you can remove the randomness entirely and still produce a valid diff.






Who said that Random Coin's dif will be generated client side? I would rather not give away too much info on this because it is VERY unique and I don't want the idea stolen before launch. I'll give a full explanation of my code the day of launch.


No one said that. I figured it could be assumed but obviously I was wrong.

The crypto crowd from my knowledge is not much of fans of centralization, especially of their coins. I know for sure I'm not. I had hoped you had answers to my concerns that didn't involve centralization or trust because that would have made this truly novel.

Thanks for your reply, I've learned everything I need to know.

Best luck with your coin

I had this problem as well when I was compiling using gitian. I'm confident theres a better solution but restarting the vm instance that I was running kvm in solved the issue. Likely something to do with residuals left from the previous dependency builds that werent removed correctly wjem they completed.

I stopped digging after the reboot solved the issue.

I did it ! Just export your dogecoin privkey and import it on the dgb wallet. Works fine !
That really works? O.o
Wow... I wonder how those .dat files work anyways

Interestingly enough because of how private keys are generated and how addresses are validated in the clients in any coins based on bitcoin if the address prefix is the same, 'D' in our case, both addresses and private keys will be valid on both coins blockchain. Thats not to say your coins come with you from one blockchain to the other, just that the private key generated for an address on one blockchain will also be valid on the other if the address prefix match.

Now, you may ask yourself (as I did when I first discovered this), well, isn't this a security concern. Can't somebody on doge coin generate a private key that could access your address? This however is incredible improbable (or unfeasible depending on which term you like better) and no more likely then someone on the DigiByte blockchain generating an address that is already in use on the DigiByte blockchain. I could get into the absurdity of the numbers but needless to say the amount of possible addresses is beyond large. Imagine the number of atoms in all the matter on earth... and that would only be a small portion of the possible address space.

People in the past have occasionaly sent their DigiBytes to a Doge address on an exchange. Because the private key to the address they were sending already existed on the Doge blockchain and was owned by the exchange, the exchange was able to import the private key from one blockchain to another and redeem the otherwise lost coins.

This of course is totally up to the desecration of the exchange.

We've looked into possible solutions but have only come up with bandaids that aren't worth implementing and don't actually fix the underlying cause.

My only suggestion currently, as poor as a suggestion as it might be, is to remain diligent about verifying you are sending to a DigiByte address. Almost every instance of this has been related to DigiBytes being sent to an exchange. Double check your on the DigiByte deposit page when you generated a deposit address and that your not mixing up Doge and DGB or anyother coin that might start with D  

It also doesn't hurt to send a very small amount and verify it was deposited to your account correctly before you send a larger amount.  Its much better to risk losing 1 DigiByte to the void then 50k.

Why don't you have an iPhone app? (seriously, I feel like there is a lot more to this answer than I realize)

You can conjecture all day but the bottom line is Apple doesn't allow anything to do with sending or receiving bitcoins on the app store as apparent by their recent removal of the blockchain app in February.

Here is a quote from blockchains response to their apps removal
(taken from https://blog.blockchain.com/2014/02/06/blockchain-response-to-apple/)

Quote
These actions by Apple once again demonstrate the anti-competitive and capricious nature of the App Store policies that are clearly focused on preserving Apple’s monopoly on payments rather than based on any consideration of the needs and desires of their users.

Quote
Apple’s censorship of bitcoin applications, especially when viewed in the context of removing a 2 year app with 120,000 downloads is historic and unprecedented.
