I haven't been involved with Slimcoin for a couple of years.

Has there been a hard fork since then? My (old) client is syncing (slowly) but if there's been a hard fork there's not much point.

Is this the correct git rep? https://github.com/slimcoin-project/Slimcoin/

(The hardened checkpoints in this source are very old.)

BTW, the client seems to be using a crapload of CPU. Load was past 9 on a four core server (that's more than 200% load). Once I stopped slimcoind it went back down to 2.5 (62.5% load). Is this improved in the newer client source and/or is there a way to limit it to using one core only?

Thanks!

The last one client https://minkiz.co/noodlings/slm/slimcoin-qt-v0.5.1-win32.zip

Source should be https://github.com/slimcoin-project/Slimcoin/tree/master

CPU load in my case is 1 %. If you use PoS than client is CPU intensive

Answer from Tradesatoshi

"Hi gavrilo77,

Direct coin listing fee its 0.5 BTC. The coin needs to be a bitcoin clone with similar RPC api. Coins with different APIs has other prices"

How can I staking ?
I have coins in my wallet (open) but I was never able to stake.
I already did in the console  and type "walletpassphrase yourpass 999999999999"

Unless slimcoin does it differently, the correct command would be "reservebalance false"

Has there been a hard fork since then? My (old) client is syncing (slowly) but if there's been a hard fork there's not much point.

If you are using version 0.2, I mean to remember there was a hard fork to transition to 0.3 because the consensus algorithm was changed - however, I'm not sure. Version 0.3 is the last one published by the "original developer" in 2014. Since then, there were no hard forks - only soft forks. So with 0.3.x you should be fine - however, at least with Linux I have sync problems with this client, and with 0.4 and 0.5 this has definitively improved.

Quote

Yes. The most recent code is on the "master" branch. (There is an experimental 0.6 version but I think it's far from ready.)

Quote
(The hardened checkpoints in this source are very old.)

Thanks for reminding that. I could try to update it, but maybe gjhiggins (our current "main developer") anyway wants to renew it for the next version.

BTW, the client seems to be using a crapload of CPU. Load was past 9 on a four core server (that's more than 200% load). Once I stopped slimcoind it went back down to 2.5 (62.5% load). Is this improved in the newer client source and/or is there a way to limit it to using one core only?

Yep, that is a known problem - staking needs much CPU power. You can set a high reservebalance to disable staking (at least temporarily) if the performance is a problem.

No, this is with staking disabled. Looks like I had the same problem 3 years ago - just forgot I'd already experienced it. Smiley

The client was basically taking over the entire server.

I'll give the current source a go.

I am using two clients on one PC. CPU load 0.5-1.0%. One of the client is dedicated only for PoB
On second PC CPU load is max 0.5%
On third PC CPU load is max 0.5%
I am using the last build without staking

I'll give the current source a go.

You might be able to speed up the syncing by moving your existing wallet to one side and letting it sync with an empty wallet. Otherwise, there is a nighlty datadir snapshot which might work (experiences vary):

https://minkiz.co/noodlings/slm/slm-datadir-snapshot.zip

The current version remains on test to allow me to discover all the bugs I've introduced.

I upgraded to the new source (master branch), and I'm now seeing this error when doing 'getinfo':

WARNING: Blockchain redownload required approaching or past v0.4 upgrade deadline.

This seems to imply there has been a hard fork since 0.3.x?

Current version is reported in a somewhat unusual way:

Slimcoin version vSLMCOIN_VERSION_MAJOR.SLMCOIN_VERSION_MINOR.SLMCOIN_VERSION_REVISION.SLMCOIN_V ERSION_BUILD-g154b52a-alpha ()

You should see something like this v0.5.0.0-g8e9fe2c-alpha. Do you use Windows or Linux?

FreeBSD, compiled from source. I downloaded https://github.com/slimcoin-project/Slimcoin/archive/slimcoin.zip about half a day ago.

I restored the blockchain from a backup done in January 2015, but it's still showing the message. Guess I need to resync from scratch. Sad

I'm trying to sync from scratch with the current master, but my client seems to be progressively banning every node, because of errors like this:

Code:

It has banned 20 different peers so far. It has only synced 530 blocks in 2 hours.

I'm not sure if (for example) 20f4e74f88f6f3b8a7bc is a block at the very start of the chain, or it's a peer offering a current block, which may be why it is being rejected. Could there be an issue with the code verifying very old blocks, performing post-0.4 validation on pre-0.4 blocks? Has anyone tried a sync from scratch with the current code?

Slimcoin version vSLMCOIN_VERSION_MAJOR.SLMCOIN_VERSION_MINOR.SLMCOIN_VERSION_REVISION.SLMCOIN_V ERSION_BUILD-g154b52a-alpha ()

The good news is that the above confirms you haven't actually been using the latest sources to compile from, which is possibly why the issues look familiar - we have an entirely different, fresh set of issues today Smiley.

git log should show the last commit hash as 7d4cacc05c31b3746a349923293cfe4358693e9c - the github default is unusual in that it isn't the master.
