First Proof of Burn currency / Community account

I' m reorganizing the OP of this thread now and have already changed the title to a less "official"-looking but still bold version.

If some of you have any suggestions what can be added (or deleted), be welcome

Could it be possible that I'm on the wrong chain? It happens on two machines, both having the blockchain data from gavrillo77. It looks like the trust parameter is different, can someone explain what it is?

Thanks, sounds logical, I'll try that and let you know if it worked. So far, the Linux machine has minted 120SLM in one day. Rasbperry still loading the blockchain.

I augmented the Slimcoin README.md with the peercoin.net instruction on how to mint with an encrypted wallet.

The raspberry pi should be able to read gavrilo77's mega-hosted copy of the files, they will be 4.8-based.

Cheers

Any opinions on the locking / unlocking of the GUI client? It says "Minting suspended due to locked wallet." I don't know how to take this

Minting instructions are detailed here: https://peercoin.net/minting-guide

Quote

1. Ensure your wallet is encrypted with a good passphrase. Write this down and keep it somewhere safe; if you forget the passphrase you will lose your coins. The wallet encryption option can be found under the settings tab in the Peercoin-Qt wallet program.

2. To start minting go to help -> debug window -> console and enter:
walletpassphrase abc 999999 true
where "abc" is your passphrase and "999999" is the time you want to mint for in seconds. You can change the amount of time to whatever you like, but it is usually easiest just to set it at a very high number. If your passphrase has spaces then enclose it in quotation marks.

3. Clear your passphrase by pressing Ctrl-L.

4. You can check you are minting by looking at the little padlock in the bottom right corner of the client. After a few moments it should become unlocked. If you hover your mouse over it, it should say "Wallet is encrypted and currently unlocked for block minting only".

Yes, it is a little unexpected. I'll take a look at the possibility of importing the corresponding peerunity code which apparently resolves the issue. (Doesn't redress the issue of decrypting the wallet tho').

Also, the GUI client, how can you unlock it? On Mac OSX I can't find this option anywhere. Once locked, it just stays like that.

As inherited, encryption of Slimcoin wallets is one-way:

https://github.com/slimcoin-project/Slimcoin/blame/slimcoin/src/qt/bitcoingui.cpp#L855

Probably, the only way out is to sequentially feed dumpprivkey with all the addresses in each account (making a note of the label and the privkey), closing the app, moving the wallet aside, re-starting the app and then sequentially feeding importprivkey with all the privkeys and labels. That should restore the wallet accounts, addresses and balances in the new, unencrypted wallet.

The staking is still disabled ?
If yes how to enable it again?

How to enable staking was described in an earlier post but that was some time back. I think it's conjecture rather than diagnosis but whatever ...

Whilst syncing from 0, a wallet successfully staking before it is fully synced will create for itself a fork of the blockchain containing the newly-minted block at that point - e.g. at 12th August 2015 02:34:12, if that's how far the sync has gotten when the staking occurred (aiui). That basically borks the client until that forked blockchain data is expunged from datadir.

As a workaround to prevent premature staking, a reserve of 1000000 was hard-coded into the client (and which I preserved in the migration).

To enable staking in practice, either collect more than 1000000 SLM or, more frugally, add the following to slimcoin.conf:

Code:

reservebalance=0

I just started a week ago myself. It seems it's very actively developed, since December last year. Atm is delisted, somebody wrote a few days ago he is trying to get it listed again on bter. Other than that, it's fun

Welcome aboard.

Hello,

I just started to try this coin.
what is the status about development, exchange etc... ?

thanks

Well, it took a while, but I just had my first coins, on the Linux machine. The raspberry pi is still downloading the blockchain (I expect to take days, unless I find somewhere some blockchain files that are compatible with the db4 version I have on it - I tried to copy from OSX and Ubuntu but the db4 on the pi complained the files are corrupt).

I sent 5 coins to the OSX desktop client - all good.

From there, I burned 4.99, waiting to see what happens now

Thank you, yes, it does help a lot!

On a side note:

- running a slimcoind instance on a Ubuntu 16
- running a slimcoind GUI on a Mac OSX Sierra
- running a slimcoind instance on a Raspberry Pi 3

So far, only the Ubuntu instance is synching ok and it "produced" a few coins (minted the ones above, waiting to mature).

On Mac OS I have no idea if it mines or not and on Raspberry I just started it, looks like it has trouble finding peers, it cycles through 2 IPs last seen 4-5 days ago.

Both the Mac and the Raspberry are behind a router and have non-routable IPs. I made a port-forwarding to the Raspberry non-routable IP for port 9050. The Mac is downloading the blocks correctly, so the port may not be a problem, but I have no idea if it mines.

I'll keep you guys posted.

"newmint" means coins that have been minted? Where can I find them? "balance" shows 0.000.

Slimcoin it's getting confusing

You need to wait until your block matures. The below line in main.h tells us this takes 500 blocks until you see it under 'balance':

It varies, between 1000 and 1500 and there are already 3 other instances of minergate mining monero on it. Slimcoin is just a test.

Which reminds me: does anyone knows of the exchange listing status?

For some reason, it worked, here's what I have in getmininginfo on the linux machine

{
"blocks" : 859892,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.01151753,

"hashespersec" : 1093,
"networkghps" : 0.00033882,
"pooledtx" : 0,
"testnet" : false
}

According to the calculations above, I should get a block every 6 hours, at worst. I'll keep you posted.

1k hashes per second is quite low for 8 cores. What CPU is this?

On the linux machine I entered slimcoin setgenerate true 8 (it's a maschine with 16 cores). From your experience, how long it takes until I get to mine a block?

Also, in the GUI wallet, there's an option about mining? Is that thing doing anything atm?

Thanks!

Get your hashes per sec with:
slimcoin gethashespersec

Current difficulty is 0.01059393, this is 0.01059393 * 2^32 (~46 mio) hashes on average required to mine a block.

~~gethashespersec returns zero. Auch. I suspect there's something I should do in the slimcoind.conf, but other than rpcuser and password I have nothing in it atm.~~

On the Mac machine I had no luck, although I let it run for the whole night. Mining is shaky so I stopped it.

Is there any way to "tell it" setegenerate true 4 or whatever on the Mac?
