I'm hitting testnet right now with 33 MH/s after about 8 hours of less than 1 MH/s.  DGW3 is very slow.  It takes more than 20 very fast blocks before the difficulty starts to rise.  It also takes way too long for the diff to fall after the heavy hash leaves.  It's very smooth at low diff - no sign of dips - and handles gentle ups and downs beautifully.  But an attacking pool can hit us for 5 minutes and leave us hanging for hours.

I hate to say it, but of DGW, digishield, or our current PID, PIDs in third, DGW in 2nd, and Digi's first.

I still want to try the Phoenixcoin multiple moving average method, and want to find a way to change Digishield's 1 block retarget to 3 or 5.  We'll see.

That is the only problem with the DGW.

I'm hitting testnet right now with 33 MH/s after about 8 hours of less than 1 MH/s.  DGW3 is very slow.  It takes more than 20 very fast blocks before the difficulty starts to rise.  It also takes way too long for the diff to fall after the heavy hash leaves.  It's very smooth at low diff - no sign of dips - and handles gentle ups and downs beautifully.  But an attacking pool can hit us for 5 minutes and leave us hanging for hours.

That is the only problem with the DGW.
We've just adjusted some settings to see if we can speed DGW up a bit...

Thanks for checking in!  What difficulty adjustment process do you like?
Andy

By the way - this is Digishield in the real world with more hash.  Look familiar? Wink

DGW3 performs better when the block look-back is trimmed to 12 from the default 24 blocks.  It's not quite as smooth during low diff periods, but responds much better when a 40x hash rate increase happens.  The 36 block average at the top (not including the hour-plus top block) was 6:30.  I expect the block average to exceed 10 minutes on the 'down hill' side when that happens.  Right now, though, I'll leave my 30 MH/s and see how the algo acts now that it's adjusted to the hash increase.  (So much for expectations - things are coming down much faster than I thought they would...   Shocked)








The bad news in all of this is that when my 33 MH/s is on testnet, it's not on mainnet.  Expect mainnet blocks to slow for a bit...

The new primary seed node, catcoinwallets.com, and the block explorer are running on their new server tonight.  DNS propagation should be complete by now.  There's a message on the old server - if you receive it, please post the message. Wink

Testnet was reset a bit ago as well.  The algo's still DGW3, but we changed some of the settings a bit.  We're hoping for smoother performance in steady state and a bit less overshoot.

That's all I have for now.

Andy

Testnet...

Still working with DGW3.  The last round of experiments did improve the reaction speed of the algo when the hash rate increases by more than 30x, and the difficulty 'can' come down fairly quickly.  The steady hash rate performance isn't as smooth, though, and exhibits slow cycles that result in long blocks on top and difficulty dips in between.  A hash influx of about an hour is enough to leave us high and dry.  It appears that DGW3 can provide some resistance to massive difficulty changes, but we have to pay for that with fast blocks early, and the probability of some very long blocks on the other side of the 'attack'.

I think it's time to put DigiShield up and abuse it for a while.

If anyone's got other ideas, this would be a great time to post them.  Thanks in advance.

Andy

Overnight, testnet was changed to run Digishield with a 1-block retarget.  We'll see how it behaves with very low hash rates, as well as when assaulted.

http://testnet.geekhash.org/

We continue to seek out and explore various exploits as well.  We intend to select the difficulty adjustment method that provides the most even delivery of blocks in as broad a hash rate environment as possible, and one that is as immune to time warp and other exploits as possible.

Thoughts or suggestions?  Bring them!

Andy

I would submit and make available the Penta algorithm developed in C#, but we would need a volunteer programmer to translate it to c++ and provide a couple of conversion functions to translate native difficulty representation to the floating point representation and back, to bring the code to the state where it can be tested on a testnet. The code is already testable in the simulator at catcoin-algo.org but it is understood and agreed that code must be converted to C++ and its performance must be validated in the testnet environment before it can be a candidate for implementation.

Thanks Eric.

I'm not in charge of testnet - that's Blak's domain.  He's made clear that he'll run any catd that can be compiled.

My C++ skills have advanced enough to allow adapting functioning code, but I'm not the guy you want to convert your algo.  (Not saying that you've asked as you haven't.  Just communicating that while I would if I could, I'm not in a position to convert your code.)

I'd be interested in reading your thoughts on how your penta-moving average system compares/contrasts with KGW, as KGW consists of four exponential moving averages and one SMA.

I'm looking for a community position, please.

When he was part of the development team, Hozer accepted donations and managed the 'forks of 2014' insurance fund.  It's my personal opinion that Hozer should submit an accounting of the funds received, and that those funds should either be transferred to the dev team so they can be left in trust to continue the insurance program, or that they should be returned to the folks that donated them.

Again - this is my personal thought and does not reflect the opinion of the dev team.

Donators:  What do YOU want done with your CATs?  Community - what do you want done?

Thanks all,
Andy

Hey cats, when do you expect the new wallet to be released with a fix to the sync issue? There are gaps as long as 30 hours happening continuously, it would be be a significant improvement to have that fixed.
