[ANN][C2] Coin2 | POS | Official Thread | BF3 | BF4 | CS:GO | Chain of Conflict

[KingArbinV]

in that case, lets see if we can open up that avenue.  remember king your talking to a non-programmer...lol...im all for minecraft and c2 being together and any new faces on c2 is a good thing.

btw if one knows a java programmer how much leg work in java programming would it take to convert the bitquest server to handle c2?

I'm not really sure on how much work would be required, or if its even possible without creating a java version of the Coin2 Wallet.

Here is the burn address again: CbUQAPuAtXJYiNri2omTSXZt8NUyq9oYph

There is a video of me destroying its wallet.dat on the Coin2Gaming channel

https://youtu.be/KofU4ejG0-o

There were 52,600 coin2 destroyed already.

Coin 2 could really do with swapping to pos3 or posa.  To encourage staking and security.

An ROI gaming venture is needed with full plan and ledger. People invest in the development, they get a return in some way.

I suspect many many people have left crypto since coin2 was given out so I would imagine many coin 2 are lost now. It would not take much interest in coin2 in terms of btc to really set if off again.

I see hyper are talking about this new gaming site and possible collaboration.

hi to all

King Arbin, i know i used to play minecraft like 10 years ago and my kids and all their friends are crazy about it now, we all know what minecraft has become.

Coin2 wallet is based on a quite old POS software. POS wallet's in general have waaaay more transactions (10Ks and more) because of staking and bitcoin data structures just was not designed for that so POS wallets are usually reeeally slow if you are staking (and you have to to secure network). Next problem is low block time - you have a huge data of 1GB+ which is mostly useless because of empty blocks (most of them have only coinbase tx which is generating new coins) but you need to scan through it almost all the time. And finally wallet devs don't fork it properly so it's really hard to keep it up to date with some bitcoin improvements in that field - it simply zillion hours of work to do.
Another problem for Coin2 and alike is that to protect coin from bashing by bitcoiners it uses scrypt instead of sha256 which is waaay slower (it was designed to be so) and block verification takes a lot more resources.

I tried to analyze the most critical performance parts back in 2015 and made some changes, see https://github.com/UdjinM6/Coin2.1/releases - it has both mac and windows binaries.

But that's basically it. I can't do anything with block time or hash algo without hardfork. And even if we forked it won't give too much benefits because history is already there and you can't just throw it away, you'll have to verify it once you install new wallet somewhere. If you want a fast working wallet you need to reconsider a lot starting from blockchain properties and ending with what wallet to fork from for a new blockchain.

Well this should be something that if it is needed the community should vote on, I agree with most that it takes forever to open the wallet, but it does work.

Maybe a different route could work, an algorithm to compress old block data but something that the wallet could read still.. not sure. I haven't really messed with actual code for almost 9 years, and even then it was just plain old C Language, kinda not sure what all better functions C++ has to offer, I just know they are similar.

Or an updated wallet(for users only) that grabs the latest transaction, goes back about 100k blocks and loads the data from there. Keeping the main wallet for the block explorer and anything else that needs the complete chain history.

Since  Dailymodo is one of us in this community, I will open a discussion with him about allowing coin2 to be used there as he knows as well as I do that we need something like this to keep interest up. Others should pm him as well. A gambling platform would be a good thing for others to come have a look at what Coin2 is about.

Actually using my recommendations (grab latest release and move your wallet every 10K transactions to a new one) solves problem more or less for current users.
Here's a little test:

Code:

03/24/16 19:34:34 Coin2.1 version v2.1.3.0 (2015-10-28 10:05:11 +0300)  <---- start
....
03/24/16 19:35:21 Loading index, loaded 960000 blocks
03/24/16 19:35:28 LoadBlockIndex(): hashBestChain=e6fd97de55d6e3ff6405  height=964277  trust=2099217867472243  date=03/18/16 18:45:26
03/24/16 19:35:28 LoadBlockIndex(): synchronized checkpoint 000005510a96f9c91fc4767e9fbb0c295abca7ff25d8dd286b3dba3a5975f374  <---- all blocks loaded
....
03/24/16 19:35:35 Done loading  <----GUI appeared

So it's ~1 minute to start GUI on my old 2010 mac which I think is fine comparing to other POS coins.

As for "goes back about 100k blocks and loads the data from there" - this means you have no blockchain anymore which makes everything else useless - it brakes most of the data structures, logic etc.. and you won't be able to stake of course. Even if it was smth like pruning which was implemented in Bitcoin Core recently you still would need to download every block to build utxo db. What you just described is closer to a kind of SPV wallet and in this case I think it should be easier to find some implementations of SPV for other coins rather than trying to fit this model into current one (i.e. like you described - current one is for services/staking, SPV - for "normal" users who just want to have ability to send/receive coins). And then maybe find someone who is ok with the code for SPV.

But again, if "normal" user will open wallet sometimes to keep blocks up to date - wallet slowness shouldn't be a problem for him.

Me personally I only find the wallet opening issue to be a problem when I have to send coins to someone to pay them, lol. Currently though it takes almost 15 minutes for mine to open, not sure if it has something to do with the amount of coins stored in it or what. 

I'm also glad you explained this out, I have no idea how the wallet actually works beyond its GUI interface. So compressing downloaded block data that could still be readable by the wallet is out too then?

[KingArbinV]

Ok as far as the talks with DailyModo go about including Coin2 as a betting option, C2 is set to be included. Should give everyone something to do with their coins other than trade at the moment.

Also in other news, ChadCrypto has decided to make a game as well other than Coin Quest: The Dark Stakes... I have been doing models most of the day for him to use in it. As far as details go, there is no working title yet, he has asked me not to tell the concept just yet, but I can say its being made in Unreal Engine. It will also be unique in a way, the games concept has never been done before and it is based on conspiracy. I will leave it to him in the future to give further details.

[cryptohunter]

can we not coin swap to a totally new chain. We did it before didn't we?

POS3 or posa look much better and really encourage staking and securing the network.

[jw_industry]

what website can I find the most accurate value of c2?

[DailyModo]

Hey guys.
Just wanted to stop by with a quick update. As some of you may know I have partnered with some real good people and we have developed www.gamebet.gg
Its an online platform where you can wager on eSports using cryptos and Steam items. In the future it will have a full casino and sports betting as well. I have been in talks with KA and my team and we have decided to support C2 in a future update which is expected to happen in about 3-4 weeks.
You'll be able to deposit C2 and withdrawal your winnings in C2 as well. Our plan is to keep expanding our site and partnerships and we hope we'll be able to shine a much needed light on C2 GameBet and GameBet coin.

re 15 minutes: hmmm.. have you tried the version I mentioned or do you still use some of the previous versions?
re compressing: if by "compressing" you mean "skipping blocks"  then no, wallet needs them all to rebuild chain on its own. You can however try to zip datadir (without wallet, logs and config files) and provide that to skip initial reindexing but I'm not 100% sure if that would actually work when you move it from one system to another.

The version I am using is the last one you worked on I believe, the one that was created around the time the blockchain got stuck.

Well, I can already hardly remember what it was and even when that happened But I believe it was "2.1.2 critical bugfix". Check version number in Help -> Debug window, mine says v2.1.3.0

guess im a version behind, i have v2.1.2.0 lol my bad

switched to the latest version, now im stuck waiting to sync again, but its ok i guess, lol

Also updated the link on the Op to point directly at the releases page instead of a specific version.

Hi wheelz.
We plan of having the sports book up and fully functional within the next 3-4 weeks. I also replied to your pm.
Thanks.
