I changed the block explorer to http://45.32.67.42:3001/ because I wanted port 80 for a pool.

I am testing a pool but it won't accept found blocks.

Here is the error from the stratum log:

Code:

Any ideas?

Ok for the block explorer, I update the adress in the website.
Glad to see that you are trying to build a pool even if I can't help you with your trouble Undecided

But if you want somebody to test your pool I'm here !

@aptcoin : it will be interesting to update the 1st post with website, block explorer and exchange. Also update the topic title maybe ?

What is the current difficulty? Is it still profitable to mine this coin? Or is it better to buy at current market price?

The difficulty is relatively low for any modern CPU, so it's worth trying. If no luck, the market is of course an option.

What is the problem requiring difficulty re-targeting? We're already using Apt-Curve, which was designed specifically for this coin. I'm not aware of further shortcomings.

It seems like you get stuck on a high n-factor of 12 or 13 for a long time then when you solve a block it drops significantly and you find several blocks rapidly and then the n-factor goes back up significantly then a block and lower n-factor a couple blocks and repeat. A smoother change in n-factor would be nice. I'm just mining this now and then to help keep the chain viable for now until hopefully some new development comes along.

Strangely enough, this is by design and it's working as intended. Smoother changes in n-factor can't really be coordinated without opening up new attack surfaces.

The issue is that it takes a long time to hash high n-factors and a short amount of time to hash low n-factors. The only real parameter that can be tweaked there is the difficulty, which helps to balance things -- but it can't be too drastic either. In most coins, the amount the difficulty can change (in either direction) is tapered so that the swings are not so large. Apt-curve specifically addresses that for this coin and allows significantly larger swings as calculated to keep the average amount of time for the last N number of blocks to match the target time. But that's an average time across N blocks, not the time on average for any particular n-factor. It still means higher ones take longer and shorter ones are quick.

If you think of it as transaction processing, it's true that the network can appear stuck for some time while working on a high n-factor, but as transactions pile up, they are all cleared shortly after unless the network is really unlucky and gets a string of high n-factors in a row.

The n-factors are truly random and are computed based on the winning hash of the previous round. It's crucial that it can't be predicted what n-factors are upcoming otherwise miners can easily attack the network by jumping in on the scheduled low n-factors and jumping out for the high ones, leaving the chain completely unviable at a high difficulty.

Thanks for the technical breakdown of the N-Factor implementation. Although it is possible to create a GPU miner for this coin it is highly unlikely that it would be able to make GPU mining significantly more productive than CPU mining at this time. However if this coin were to somehow obtain a value of any significance it would only be a short time before a GPU miner with increased hashrates would be able to make CPU mining obsolete. If you do anything I would suggest working on a GPU miner since having them public significantly increases the longevity and potential interest in the coin.

Ok with you but what more can we do than asking exchanges to list it ?

It's a shame that this coin has no further development since launch.

It's open source. You're welcome to add code or propose improvements.

I made a request to Yobit asking if we can pay them with some APT to get listed.

I also made a request to Poloniex with the new coin form request here : https://poloniex.com/coinRequest
Everybody can make the request once, take some time to do it. More interested they see with APT more chance we have to get listed.

Let's see...

Maybe you can try with Yobit. I think you have to pay 0.1BTC to get listed but maybe we can have an arrangement to pay in APT.

I have never heard of yobit. Can anyone else vouch for them being legitimate and not a scam? How long have they been around?

If everyone thinks it's a good idea, I'm supportive of you or someone else starting a donation pot. I will donate some too, although I'm skeptical of this exchange because I've never heard of them. Maybe I'm behind and they're great. Let me know what others think?

A smoother change in n-factor would be nice. I'm just mining this now and then to help keep the chain viable for now until hopefully some new development comes along.

Edit:

I've started a donation pot and funded it with an initial 30.000 APT http://45.32.67.42/address/AWPdaDQAgN5xrMMiY9rAb1CPPqG2b6E45e

If you want to donate and have an issue with me holding the donation coins we can look for someone else to hold them. But lets get that donation total over 100.000 so we have enough to do something with.

I want more action and interest with this coin so I sent 70k APT to the donnation pot.
http://45.32.67.42/address/AWPdaDQAgN5xrMMiY9rAb1CPPqG2b6E45e

Hopping this helps and it will only be used to promote the coin and add it on exchanges.
Here are the 100k, so what's next ?

I thought I might have an exchange listing but after some initial correspondence with the operator of the exchange I haven't heard anything back for a few days. I received your donation. Thank You. If it isn't used to get listed on an exchange it will be returned.
