A few quick announcements:

• The fork at block 25,000 is complete and if you have not done so you need to download and run the new wallet from https://roi-coin.com/roi-coin-downloads

• We have enhanced the new block explorer with SSL + multiple new and cool features which you can see at https://roi-coin-blockexplorer.roi-coin.com/
• The online paper wallet is in progress and will be complete within a week or two
• The community website is doing well and is now up to a login community of 276 users and growing
• We have had multiple 5 star reviews from the community at Facebook and some favorable shares in large crypto communities
• We are working hard to complete the listing at Yobit and are deciding on the next exchange we will go after
• We are readying for a large paid marketing push and will launch this once we are 100% positive that the coin is fully stable post-fork
• Last but not least we are overwhelmed and amazed at the community of this new coin and many thanks to each and every one of you!

No, that outage was done by elbandi who's managing the pool. There was an issue with pool after the fork which he fixed and posted the explanation on previous page.

This seems to be a new issue.

The graph show that the pool was down from about 10:10 am to 11:50 am. maybe it that.

I am mining for 3 weeks now and I was getting 20 coins every 40-60 minutes. It was like that before and after the fork, all the way until 4:30 PM ET.

Did something change today afternoon with pool mining?

I took a screenshot of ROI workers and sorted by efficiency to compare number of coins in the last 20 minutes. Regardless if people were mining with 7 KH or 1 KH. they made no coins. It was never like that before.

It take 360 block for confirmation or about 12 hours before coins kick in.

I have recently observed that there has been an accumulation of addresses like 45bd-----------------------  in the pool, whom  doesn´t match the look of casual ROI adresses – often with much hashpower.
These ones may contribute for the network, but the coins will never be received. Maybe a Pool Administrator should check who´s connecting with previously mentioned adresses and should disconnect this one.

I think there is simply unnecessary energy consumed.

Thank you very much to the dev who really invest a lot in this coin!!!!

Sorry for the bad English

Thank you both! very interesting!

If you go to https://roi-coin-blockexplorer.roi-coin.com/hash you can see some very cool and helpful details at our blockexplorer. Namely, Global Network Hash Speed - Global Network Difficulty and Time to Find 500 Blocks in Seconds. Also, this info keeps updating and also takes you back in time to give a historical data view.

By looking at this you can clearly see what the mining hash rate, mining difficulty and block timing has been doing.

On your Diff calculation question:

ROI Coin is using a MIDAS implementation. Without getting overly technical it looks at some things such as existing block timing, target block timing, network hashrate, etc. It then can do calculations and decide to increase or decrease the difficulty. So far it has proven to be working very well and it offers us some protection against large hashing swings. This could happen if large hashing power was applied and un-applied to the coin thus manipulating or gaming the mining.

The best way to see how well the algo has done is to use the link above. Take a look and see how the network hashrate has varied bigtime from ten's of thousands up to 400,000 hash. Now look and see how the difficulty has adjusted to compensate. Then lastly just see how jagged with big peaks and valleys the graph shows for hash rate and difficulty but when you look at the time to find blocks it runs very stable and steady. When hashrate moves way up and down and diff adjusts up and down and you see that block find time running sweet and smooth we have a winner folks

Hello,

Difficulty adjustments are performed by MIDAS.  This code was written by Mr. Dillinger and embedded into ROI coin.  It is highly effective in its response to variances in hash rate.  The trade off is block timing that is not exactly two minutes, but does a great job in keeping the chain tight, as so whale miners can't suck up the chain, leaving the coin with no transactions for an extended period of time.

We did review the four most common difficulty algos out in the world and felt this one fit nicely.  They all have their pros and cons.  And more than likely, someone will come on with an argument as to why another is better...  But so far, MIDAS has proven itself rather well, especially when we were getting hit with NiceHash miners.

You can get a better picture of how it behaves here at the BE site: https://roi-coin-blockexplorer.roi-coin.com/hash

If you would like a technical overview, you check out his page on it:  http://dillingers.com/blog/2015/04/21/altcoin-difficulty-adjustment-with-midas/  It is very informative and a rather elegant solution, for the time being.

I hope this helps to answer your question.

I think that something is wrong with the pool. For the last 2 hours I'm mining 400 H - 700 H and no coins have been generated. It does show how Hashes vary but no single new coin.

How the Diff is calculated, its like a wave sometimes?

The slowest CPU I have here is i7 3770 and they solo mine from the wallet very good. I also use the -optimineraes=1 flag and that helps a lot.

Im mining using the wallet, and yes its works just fine. 4-6 found blocks per day with Ryzen 7 1700

Is anyone Solo Mining with the wallet or is it possible?
If so what spec is your machine that is at least capable of worth doing at the current diff?

Thanks in advanced  

I had this problem and the way I found to fix was to backup the wallet file and then delete the Roi coin folder in %appdata% then start it and let it download the block chain again. Then close wallet and put my wallet back in %appdata%/roi coin.

Are you on Windows?

If so:

Please close your wallet.
Right click the icon you click to launch the wallet and then click properties.
Find the text box labeled Target:
At the end of the existing text add one space and type -rescan -zapwallettxes=2
Now click Apply and Click OK.
Now launch your wallet and it should sync just fine.

Before you launch the wallet next time please repeat the previous steps and remove the -rescan -zapwallettxes=2

If these directions don't make sense or don't resolve your issue please let me know so I can get it taken care of as soon as possible.

My wallet update stopped in 25014 block, how to solve?

Hi elbandi would you mind posting this as a github issue in https://github.com/ROIcoin/ROIcoin/issues
i agree that a variable needs to be initialized to 0, in case periods==0, ValidateCoins function will prevent it from being negative or bigger than MAX_MONEY value. Something happened with block 25107/25108 , needs more troubleshooting.

Hi, If its anything like the problem I have just had its the block chain. I am redownloading the chain now. I think a node somewhere has given a bad block.

Note to all. The Cluster Node is running fine at the min.

I will keep a eye on that. But for now my wallet has bugged from block 25102. Im just working on fixing that.


EDIT: all sorted this end block chain bugged.

Ok, cool .. Thank you
