CACHECOIN 2.0 - Community integration (Scrypt-Jane - PoW, PoS and PoN)

[coins101]

Hey, Vertoe

Yep, there are people still here  

Keen to see the white paper on proof of node.

[AizenSou]

singula's pool has been strange for days. The whole today doesn't show any transaction at all.

[LucD88]

He has been online, but no word yet..

[singula]

There are currently two issues with the pool:

There is slight problem with the stratum, as it loses connection to the coin daemon from time to time. Not sure why exactly it is doing that (it has not done that before in the past year or so) - I have to dig in the source and investigate it further, but for now I have found out how to detect that and restart the stratum as necessary.

Second problem is payouts - due to the fork and storm of orphans near block 90566 (there is fork of two branches - on one the "emergency" difficulty dropdown has happened, in the second it has not) the pool slightly screwed up and the cronjob detected a double payout (I guess the payment went to both the "good" and the "bad" branch during the fork storm).

I will resume payouts once I check the database and correct it (should be in about hour or two), although I will turn off the 'early payment' feature for a day or two until the tail of the blockchain (the block where the payouts are done) stabilizes.

Good thing is the blocks are now appearing in the wallet, so once fixed, the payments will resume and coins will flow again.

Looks like Cachecoin needs a new developer. Sad as I bought quite a few.

Looks like Cachecoin needs a new developer. Sad as I bought quite a few.

I'm still expecting Vertoe to speak up and move cache forward. If there is a real community of people interested (as opposed to a handful of casual speculators), one can easily regroup.
The only negative impression I have with Vertoe (before going MIA), was that her creative/brainstorming process was not as inclusive as it could/should have been. Other than that, she looks to be a solid coder, and intentions were well laid out when taking over.

The fork that followed the takeover, actually shows neat resilience of the people around here. Big kudos to Singula for the code analysis and pushing the fix to github. There are clearly people around with ideas and the capability of improving cache. I do hope Vertoe is around to participate in that effort, but if not, the community will surely figure out a way to work things out.

@Vertoe: As you look to be still around (your BCT profile shows recent presence), how about stopping by the IRC channel for a chat? Your ANN proposed community meetings, and I doubt you'd like to have everything on your shoulders. Some coordination is probably all that is needed right now...

Looking back at the new ANN, the main effort Vertoe is working on falls mainly to updating to Bitcoin core and a white paper for PON.

Updating from Bitcoin core, given the starting point, is a non-trivial effort. He has shown he can make the update having done it for Darkcoin.

Block 100k is the stated target time frame. 

The fork(s) is the concern.

Background
As the most of you guys might know I was before deeply involved in the Darkcoin project and left Darkcoin behind due to a major conflict how Darkcoin is centralized to a single entity.

So you now might ask why CACH?
The answer is quite simple: I want to share my experiences to with the community and build something new together . CACH is one of the few coins which was here for quite a long time and had it's up during the price push which was caused from the ASIC project. It proofed it is stability over the last 12+ months, when the nethash was low and the number of nodes also was limited. So I reached out to some buddies to hear their opinion about getting CACH up2date and beyond. The result was that there still is interest in a community-driven and stable coin  which can be enchanced with some nice new features. (Warning, spoilers ahead!)



What has been done
After a healthcheck of Cachecoin we decided that we have to clean the backyard before we  move on so and have a solid and clean foundation for future developements .
We cleaned the repository, compiled and released new clients for Windows, Mac and Linux with current nodes and bugfixes added.
Pools, Blockexplorer and Richlist were upgraded and miner instructions for scrypt-chacha written.

PoW adjustment: Block reward logarithm invers proportional to difficulty, PoW ends with Block 100K.

PoS adjustment: 5% per annum, min stake time 7 days, max stake time 30 days.

What will be done
This is the fun part as there are many feature to be added or enchanced.
Just one note for the P&D Groups, this will not be your coin, no masternode or decentralized market cloning! There are enough coins out you can play with.


PoN
PoN and PoS work Hand in Hand starting with Block 100K.
Each Node has to have it is own IP to be able to mine and create Blocks. The Algorithm below show you the Concept, we will publish a Whitepaper and also a Proof of Concept soon.
seconds = ((first 4 bytes of as integer) sha256([node IP] [last blockhash])) * difficulty / (2 ^ 32) * (15 * 60).
This way, difficulty will adjust to about the number of nodes.
When the time has elapsed, the Node created a Block and send it to the Networks. Each node will confirm this Block by connection to the Block Creator Node.
(if not already within his Peers) - just to confirm the Block Hash.
PoN and PoS Blocks are altering, only the last PoN Block is verified by IP (as IP's might already be gone)


Community integration and decentralization
We thought a lot about how the community could be integrated and we think it is absolutely most important to get the community deeply involved, that means that we will open this coin up to the dev level to the community. That does not necessarily mean that you have to be a coder to participate, it means that you can influence the development process with your suggestions. Cachecoin protocol changes can be submitted on github pull requests and will be discussed by any developer or community member and will only be accepted on broad consensus. Proven contributors can gain write access to the repositories. More complex changes can be implemented via blockchain voting (compare Bitcoin BIP0034 and BIP0066). Implementing BIPs for Cachecoin is possible if the demand is there. Request BIP numbers on github submitting a proposal.

There will be monthly community meetings to decide which resources should be used to move forward. There will be no centralized structures like a foundation or a single-point-of-failure-developer.

Community backing
Some of you already decided to be a backer of this project and either gave CACH to the bounty pool or you gave BTC to the community pool.

The community pool is where funds are stored until they are allocated to tasks. If we cannot find a developer via the initial bounty pool or the bounty pool is depleted, we can use the funds which came throught the community as a donation to align tasks. The funds will be used to finance the development according to the roadmap. Since the community pool is filled with bitcoin, we can use bountysource.com to crowdsource technological progress. The funding address is: 3Fr2ExH2Z6dTnTv8MZMkAbwPY92o4hhXHh

The bounty pool can be refilled with CACH via: CcxCHNpoPZmnfu37vfJjFPcNKAvMLJYTej

Roadmap
The next big thing is moving CACH to a Bitcoin 0.11 fork to ensure we have a solid codebase for future developments. This is the most useful milestone. The old wallet is.. yes: old and based on a 3 years old bitcoin/peercoin/novacoin/yacoin branch.

Implementing PoN which will kick in @ Block 100k (stay tuned for the whitepaper).

For solomining you have to add gen=1 to the cachecoin.conf file. You can also enable solomining in a wallet by going into the debug console and entering setgenerate true or issuing that command via a RPC connection.
Due to the coin's current difficulty solomining is not recommended. You will earn more coins by contributing your computer's hash power to a pool.


Proof-Of-Stake
Cachecoin utilizes Proof-of-Stake (PoS) mining that generates more coins when you retain your coins for 7 days. When the coins from a particular transaction become 7 days old, they will be used by your wallet to perform Proof-of-Stake mining that will generate new coins if you solve the block.
Just like a normal Proof-of-Work block, these PoS blocks require 520 confirmations. Once the PoS block has reached 520 confirmations, your staked coins and the reward will be available again in your wallet. These coins require to age another 7 days before they can be used in POS mining. The PoS is not CPU intense and there's no need to set anything in order to mine PoS. It's done automatically.

It is important to note that when your coins are staked (having reached 7 days of age and are used for a PoS block), these coins will be owned by you but unavailable to transfer until they are fully confirmed.

For those who want to exclude a certain amount of coins from Proof-of-Stake mining, you can run the client with the -reservebalance argument. This argument allows you to specify a certain amount of coins to withhold from using as a stake.

PoS - Getting started
By default the wallet will submit coins for staking ( see above). If you opt to encrypt your wallet (this is strongly advised) staking will stop - as encrypting the wallet means no coins can be sent without entering a passphrase. If you opt not to encrypt your wallet  then staking will work fine with no extra configuration needed.

"Unlocking" the wallet allows coins to be sent and received for the purpose of staking. Unlocking the wallet is not the same as decrypting the wallet - as the wallet passphrase must still be entered to send coins to another wallet (as per normal if you encrypt any cryptocoin wallet). Unlocking the wallet allows coins to stake whilst keeping your coins safe.

To unlock your wallet, enter this command in the QT wallet client debug console located under help menu:

Code:

walletpassphrase thisismypassphrase 99999999 true

Replace "thisismypassphrase" with your encrypted wallet passphrase. This will unlock your CACH wallet for staking for 1157 days (99999999 seconds = 1157 days). Upon restarting your client you will need to re-enter this command, as it is not saved. By entering this command and having your wallet encrypted, you will be able to stake your coins whilst having a properly encrypted wallet.

Verote,

I have been involved in crypto for few years. I've been in some shit coins, lost some, and won some. As I gained experience I realized it was better to bet on a good developer rather than some novice, which is why I invested in Cach. It wasn't until you showed up that I decided to do so.

As I was reading messages on IRC I got the feeling that you've become discouraged by the trolls and investors rushing you. I can understand how you feel, but you have to consider the rest of your coin holders who gave you trust and invested only because of you!
Being a dev or leader of certain business is tough, but you can NOT let your personal feelings play apart in your investors portfolio.
I hope you can overcome your discouragement and continue to work on this coin.

Hi,

I used always this script with my 750ti:

cudaminer.exe -a scrypt-jane:YAC -H 2 -L 8 -i 0 -l t64x1 -b 4096 -m 1 -o stratum+tcp://cach.catcoin.cz:3333 -u xxx -p xxx


but for several days it does not work anymore... something changed?

Thank you in advance  

[myagui]

@mik57:

Nothing changed recently that would affect your mining settings, but you are not selecting the CACHE parameters, you are selecting YAC instead. If they are not exactly on the same nfactor schedule, that would be enough reason.

If the problem relates to the nfactor selection, this one should work:
cudaminer.exe -a scrypt-jane:16 -H 2 -L 8 -i 0 -l t64x1 -b 4096 -m 1 -o stratum+tcp://cach.catcoin.cz:3333 -u xxx -p xxx

Vertoe, to validate that post. Please sign with your PGP key.

-----BEGIN LTC SIGNED MESSAGE-----
i'm vertoe and no longer able to access my bitcointalk account - verify this message with the litecoin address found in this post ?topic=441215.msg4847316 - the last post written by me is ?topic=400389.msg11381772 - yes, i never wanted cachecoin 2.0 and allowed the extended cachecoin team to use my account - i couldn't stand the pressure of investors sending me daily half a dozen pms on all channels - screw the altcoin scene - i'm out anyways - and kal, sorry for breaking your coin while trying to rescue it. farewell.
-----END LTC SIGNED MESSAGE-----

So a hacked BTC account is signing a message by reference to a hacked BTC account message?

[myagui]

[...] So a hacked BTC account is signing a message by reference to a hacked BTC account message?

His github message is signed by an LTC address that is linked in a bitcointalk quote. Since the quote itself can't be modified by the current holder of the vertoe account, it is reasonable proof of her identity. In short: the message was posted by someone that holds control of: vertoe's github account + vertoe's prior known LTC keys.

If the statement holds true and represents vertoe's take on CACHE going forward, I am thoroughly surprised by the total lack of character/morals. Oh well, just another day in Altcoin land I suppose.

Cachecoin Information: https://bitcointalk.org/index.php?topic=400389.0

Cachecoin P2Pool node: http://q30.qhor.net:8336/

Pool Information

• 1% p2pool node fees
• PPLNS payout with vardiff
• Direct payouts to your wallet without being hold by any insecure pool wallet
• Dynamic worker tracker frontend - just enter your address and watch the stats

Cachecoin P2Pool node: http://q30.qhor.net:8336/
Cachecoin Node scanner: http://q30.qhor.net:8337/


Difficulty
If you wish to manually control your pseudo-share difficulty outside of the range provided by the dynamic system you can do the following:

Code:

Dogecoin Address+0.00000116 x Hash Rate in KHash

For example for my R9 270x I use:

Code:

300 x 0.00000116 = 0.000348
CP8qRQAESbU6CqJvsjh2tCSZWLQnhQd3n3+0.000348

The following are suggested targets for various hash rates if you want to grab one quickly:

KHash/s	Difficulty
50	+0.00005821
100	+0.00011641
250	+0.00029103
500	+0.00058207
750	+0.00087310
1000	+0.00116414

Please note

• P2Pool payments can take up to 24 hours to ramp up after you start mining, please wait this long before seeking assistance
• Payouts require that you solve at least one share of difficulty greater than the P2Pool share target per day.
• Decreasing intensity can help your stale rates massively, and will improve your payouts in most cases.
• You will notice an increased stale rate in your miner compared to a traditional pool, this is normal and expected behaviour for P2Pool (~5-10%)
