Are this normal? it happening like every second non-stop...

[Plainkoin]

CPU mining by one click? sounds like a God's gift.

Please note the basic wallet miner, needed to be as universal as possible.  So out of the box, it may not be as effective until you experiment with some of the Flags, which can help to get more hashrate.

Some find using the 3rd party miners to be even more effective.  Due to the array of CPU architectures out there, it will take a little trial and error to dial in you best settings.

Personally, I just use the wallet miner, no flags...  Too lazy.

Perhaps will remove and reinstall wallet again... perhaps it might help...
Dunno... Or I'll just stop mining and try to find some other coins...
And it's not that it was not working.
Found arround 20 blocks in the days before 1 Januari.

If someone has a suggestion on how to get this going properly, please let me know...
Else I have to go to the pool... And thats less profitable for me.

Thanks for any help!

The 8 Blocks I found during the day also got rejected.
Thats really sad, first mine about 24h on the pool for nothing and now seeing the
blocks from walletminer get rejected

[altrego]

Can somebody tell me, please, is cluster mining working well? Got no rewards during around 5-6 days period. I using 4 threads with 35-40 hashes for every thread. I just totally unlucky, or something wrong with my configuration?

I just realized the same thing was happening to me when I went back and looked at the logs...sigh

If you read a couple of posts back you see a lot of us have issues with mining this coin.
I stopped mining until we have an answer if it is fixed. Or how to fix it.
No need in wasting cost for rejected blocks.

[rovasti]

Weird that coinpool going down didnt affect the guy who has placed a 640 Kh/s order on nicehash.... or nicehash getting hacked... well maybe 1200ish euros is not that much...

Ok, thank you. I guess the problems was with only mining pool.

Is there any known p2pool or MPOS Pool Software available for hodl Algos? I want to setup a pool, so that we have at least two pools...

That's normal logging coming out of the wallet miner , it shows you the speed and result of the hashing...

Hi please submit a github issue for this so we can help you further, forum is not a good place for technical problems.
Can you check that getblockhash 32685 shows 0000000de25dc81231f2e90d7bf2fe00f20db2eaf34e4d0b2178655148de2ba0 ,
otherwise you are on the wrong chain and i can provide you a command to switch back to main chain.

you don't need it, just using ROIcoin address is fine.

[Boolenatik]

The last transaction from pool I had 31.12.2017 — 16:25
From that time - 0 income on my wallet and I didn't stop mining for all that time.
I had somethig about 500 coins on miner address, but now it's empty and I had received nothing.

Well, I hope it will come back and will be working properly one day, but for current period solo mining from the wallet (or may be mining in cluster) — will be better choice, if you want to get some coins.

http://coinspool.cu.cc/info_roicoin

Minimum payment - 20000000 wtf?

Did check the blockhash, and it is exactly the same as above.
Put all the network nodes from the blockexplorer in my ROIcoin.conf.
And have now 12 connections to the network.

In good faith started up te miners, eager to see if it would work this time.
So I let them run for a while. They found two blocks, and again both blocks got rejected.

ok one more thing to try , backup your wallet.dat and then start with the following flags:  -rescan -zapwallettxes=2
wait till you see in the debug.log "rescan    29333ms"  , then try again.
