The pool uses PROP payout system with 1.5% fee

Turbo CACHeCoin Pool. Fastest payments! Early payouts!

Early payouts explained

Major improvements are now coming to the pool! Early payouts are now active!
Pool can pay for blocks having only 90 confirmations under good conditions (instead of usual 520).

Early payout! Coins from this pool can be paid out in only 17% of the time needed to get the usual 520 confirmations. A truly unique feature available only at this pool!

CACHeCoin needs by design 520 blocks for coin maturity - after mining a block, you usually need to wait for 520 confirmation (approximately 5 days) to be able to move the coins to another wallet. So if you mine on any pool (or even solo), your mined coins will not be available to you for 5 days. But not here - we have find a way around that limitation and we pay to miners earlier!

How does it work?

We have lowered the delay between mining coins and paying them out by adding a buffer (supplied by pool operators) to cover the difference. Buffer is used to pay for unconfirmed blocks, which in turn enter the buffer. Once they become confirmed, they are used again for more expedited payments. Mathematically it is zero-sum system, so it can work forever.

As a result you receive coins approximately between 1 and 3 days after mining them, based mainly on rate of pool hashrate to network hashrate and also on block time gaps and block values (the buffer is not infinite :). Rough estimation is that for pool hashrate up to about 20% of network hashrate, the coins will be available in least possibhle time - slightly less than 1 day after mining the block - a nice improvement over standard delay of 5 days before being able to be paid out! Still, even when the pool hashrate increases to 50% of network hashrate, the delay between mining and payout will be increased only to about 2-3 days - approximately half the waiting time of other pools.

You get exactly the same amount of coins as usual - but you get the coins earlier!

Current payout system performance: Based on amount and value of mined blocks in past few days and size of the early-payment buffer, the pool can pay early for blocks with at least 90 confirms (17.31 % of nominal time)

Note: To check current performance of the early payout system, you can also check Blocks page and look for blocks marked "Paid early" (blocks that are still unconfirmed, but miners were paid for them).

Second improvement is implementation of cold wallet system. Unpaid coins from users without mining activity for more than two months can be moved offsite to a cold wallet. At least a week before actually moving the coins to cold wallet, user receives a reminder to withdraw their coins on their configured email. If user does not withdraw the coins, coins will be moved to cold wallet and amount of coins in cold wallet will be indicated in account detail (note that the field is hidden if user does not have any coins in cold wallet) Payouts from cold wallet are done manually by pool operators, so some delay (few hours or at worst few days) between requesting and receiving the payment can be expected. This reduces amount of coins in server wallet to a minimum, making it much less attractive target for any evil-doers.

Now recovering from a fork, posted Aug 10, 2015 at 09:05 by qqq

Recovering from a fork, will run payouts once the mess is cleaned up. As the coin became a PoS only coin at block 100000, the mining has now ended :(

Fork, posted Jun 26, 2015 at 03:36 by qqq

Cleaning up the mess 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). New blocks are now appearing as they should, payments should gradually catch up as the database is checked

The 'early payout' feature is temporarily turned off (so payments occur after 520 blocks as dictated by the coin specs) until the confirmation threshold passes the orphan storm.

Then it will be turned back on and set back to 90 blocks.

Stratum - change of parameters, posted May 1, 2015 at 02:06 by qqq

The initial difficulty is now halved on the stratum and minimal difficulty is 8 times less. The stratum target for vardiff is kept set to 30 seconds. This should help miners with smaller hashrates to mine more fluently.

Nfactor 13 -> 14, posted Jul 19, 2014 at 03:10 by qqq

NFactor now changed from 13 to 14, making mining more difficult for everybody.

You may want to retune your miners to achieve optimal performance at this Nfactor.

Block explorer on a fork - do not rely on it, posted Jun 6, 2014 at 03:46 by qqq

If you are unable to see your transaction in a block explorer - the block explorer is using buggy wallet version and is on a fork of the chain (as you can see in the explorer, there are actually no PoW blocks in the last 6 or so days at all). To verify that you have received the coins, use the latest version of the wallet and do not rely on the block explorer until it is fixed by whoever is running it.

Fork, posted May 31, 2014 at 16:14 by qqq

Due to the recent fork, some of you may have received their mined cachecoins with transactions to the now forked-off chain.

It seems 4 users are affected by the issue.

These transactions will be checked and if found to be not redone in the new blockchain, they'll be repaid manually in the evening, once things settle down.

N-factor increase is near (from 12 to 13), posted May 30, 2014 at 02:54 by qqq

Soon (31 May 2014, 10:39:55 GMT) you can expect increase of Nfactor from 12 to 13. Expect decrease of hashrate to approximately 50% of current hashrate, you may also need to re-tune your miners if you have tuned them (voltage, overclocking, ...) to maximize the hashrate at current Nfactor.

Mandatory update and short downtime, posted May 30, 2014 at 02:06 by qqq

Due to mandatory CacheCoin update also changing the block format, the blockchain needs to be redownloaded.

Coin daemon will be updated shortly - expect approximately 5 minute pool downtime.

EDIT: Done. Daemon updated, frontend have now caught up with the blocks too. Happy mining.

N-factor increase is coming, posted Apr 12, 2014 at 13:49 by qqq

Soon (12 Apr 2014, 21:34:51 GMT) you can expect increase of Nfactor from 11 to 12. Expect decrease of hashrate to approximately 50% of current hashrate, you may also need to re-tune your miners if you have tuned them (voltage, overclocking, ...) to maximize the hashrate at current Nfactor.

Downtime due to kernel upgrade, posted Mar 29, 2014 at 23:48 by qqq

Due to the necessary kernel upgrade, the pool will be offline for few minutes around 1:00 CEST tonight. We apologize for any inconvenience.

Recommended cgminer settings for Nfactor 11, posted Mar 9, 2014 at 03:39 by qqq

Based on suggested settings for mining Scrypt-jane coin with Nfactor 11 from https://bitcointalk.org/index.php?topic=413978.msg5435799#msg5435799 I've put a recommended parameters for mining with cgminer. You can try them if you are experiencing troubles with mining, or if your hashrate is lower than expected.

The suggested settings would be:

HD7950 (1044/1500), expected hashrate about 100kh/s

Important - Mining information!, posted Feb 24, 2014 at 19:11 by qqq

Note: for mining CACHeCoins, you need special miner with scrypt-jane support AND you need to set the correct mining parameters:

nfMin = 4
nfMax = 30
nTimeStamp = 1388949883

Recommended miner (based on your mining hardware) is:

nVidia cards - use cudaminer

Information page: https://bitcointalk.org/index.php?topic=167229.0

AMD (ATI) cards - use CGminer

CGminer patched by Robert Davidson is recommended to mine with AMD cards.

Information page: https://sites.google.com/site/rmdavidson/ (note- you need to use 0.02-sj, 0.04-mp does NOT have scrypt-jane support)
If you are getting hardware errors when mining, try decreasing the intensity. Some people have reported that decreasing from -i 13 to -i 12 helped and they are mining without hardware errors again.

How to verify if I have the miner and parameters set correctly?

  1. Start mining
  2. Login to the pool, click on "Dashboard" in the left menu and look at Prop Stats
  3. If number in "Your Valid" row is significantly higher than "Your Invalid" row - you have the miner set up correctly. Happy mining!
  4. If number in "Your Valid" is zero or close to zero and you see only number in "Your Invalid" row increasing - you have made some mistake. Please recheck the miner and its parameters. If you fail to fix it, please contact support for help and provide information about type of your mining hardware and what mining program and you use and its parameters.

Nfactor increased, posted Feb 23, 2014 at 12:28 by qqq

Nfactor increased few hours ago, which means mining will require more memory on the GPU.

If you are getting hardware errors when mining, try decreasing the intensity. Some people have reported that decreasing from -i 13 to -i 12 helped and they are mining without hardware errors again.

Fees lowered!, posted Feb 20, 2014 at 18:49 by qqq

Many people joined p2pools or the second pool and helped to distribute the hashrate more evenly. Thanks for that.

The pool hashrate is now at safe levels and are no longer nearing or over 50% of the network hashrate, so I am lowering the fees to 1.5%.

As a small incentive to join the second pool (with almost identical configuration) at http://pool.cachecoin.net/, I will lower the fees there from 1.5% to 1.3%.

Even if you wish to continue mining here, I suggest registering at the second pool and setting it at least as a backup pool.

> 51%, posted Feb 18, 2014 at 19:34 by qqq

As the pool is now again over 51% (and that brings several risks, like making the pool a possible single point of failure), new registrations for the pool are now closed.

Please distribute hashrate more evenly.

New traditional MPOS pool with almost identical configuration (PROP, vardiff) is set up at http://pool.cachecoin.net/.

If you have hashrate over 200 KH/s, you may also consider joining one of p2pools.

Instructions for joining p2pools: https://bitcointalk.org/index.php?topic=400389.msg5187947#msg5187947

Please start mining either at the second pool - pool.cachecoin.net (half the fee, only 1.5%) or one of P2Pool nodes (fee varies node by node, usually around 1%).

As an incentive to distribute the hashrate more evenly across the pools, fees are raised here temporarily to 3% until the hashrate of this pool gets below 40% of network hashrate. Once enough people move to second pool or to p2pool nodes, the fees will be lowered back again to 1% - 1.5% based on current situation and hashrate distribution.

Edit: current situation looks good, fees are now lowered to 1.5%

Registrations reopened, posted Feb 17, 2014 at 09:18 by qqq

As the hashrate percentage dropped to 30%, I've reopened the registrations.

New registrations closed temporarily, posted Feb 17, 2014 at 00:05 by qqq

As the pool is still over 51%, new registrations are closed temporarily.

Use one of p2pool nodes listed at http://q30.qhor.net:8337/ for mining, in the meantime I'm cooperating with others to set up another traditional pool (or two) elsewhere.

Pool over 51%, fees changed back to 1%., posted Feb 16, 2014 at 19:15 by qqq

Since the pool now has become popular and has over 51% of network hashrate (I do not plan to abuse that, but I understand that many people see this fact as a potential risk), I am raising the mining fees back to 1% as it was before 1st February - the same fee as is used on p2pool.

I hope this will encourage more even distribution of the hashrate and some people will join one of the other pools, getting this pool's hashrate below 40% of network hashrate.

Consider joining other pools, like http://cachepool.cryptoprojects.eu (once the maintenance there is over), or one of the p2pool nodes listed at http://q30.qhor.net:8337/

Coin maturity = 520 blocks, posted Feb 14, 2014 at 21:48 by qqq

To avid further questions about unconfirmed coins:

The coin is designed to mature (i.e. you are able to send mined coins elsewhere) after 520 confirmations (i.e. coins from block X are available once block X+520 is mined), and considering the coin is designed to have blocks 15 minutes apart, it can take sometimes 5 days for your coins to be available for payout. So be patient - these are design parameters of the coin itself and I cannot change it.

Long maturity helps against hypes, multipools joining and then dumping lot of coins suddenly on the market and other destabilizing effects, but as a downside, you have to wait a bit for your coins.

Maintenance done, posted Feb 5, 2014 at 21:47 by qqq

Found possible cause for not being able to find a new block. Fixing ...

Had to manually set last 6 blocks as orphans to fix the fork issue, probably caused by a lot of outdated clients out there...

I fixed the orphaned block, although it does not seem to be the cause of not being able to find a new block. Restarted stratum and coind.

But a while ago a block was found - so either the restart helped or the bad luck ended.

Mining fee lowered, posted Feb 1, 2014 at 04:06 by qqq

I have lowered the fee from 1% to 0.5% and lowered minimal auto-payment from 1 CACH to 0.5 CACH

Nfactor increased to 8, posted Jan 27, 2014 at 02:15 by qqq

NFactor in scrypt-jane PoW just increased from 7 to 8, increasing the mining difficulty for everybody.

Everybody expect to get a slightly lower hashrates from now on.

Changed settings, posted Jan 24, 2014 at 02:27 by qqq

Lowered minimal allowed value for automatic payment to 1 CACH (you can set it in "Edit Account") and also lowered the txfee to 0.01 CACH

So now you can receive the coin payments from this pool more often if you wish.
