Fixing the difficulty adjustment algo won't change the scarcity - it will make the difficulty adjustments more linear instead of hopping around so wildly. There's currently simply too few data points being used for the calculation, which skews the average badly. With more data points to calculate from, the curve will be much smoother and predictable. It won't (shouldn't) change the number of blocks per hour.

Yes, as far as I can see, we're getting the right number of blocks overall - it's just we have high variability on the block times. I think the difficultly adjustment might be making that worse.

What I'm leaning towards is taking an average of three time periods - previous 10 blocks, previous 60 blocks, previous 240 blocks, and limiting the adjustment each block to a maximum of 5% up or down.

Are there any other coins that handle this well? I see Freicoin has an advanced diff adjustment - maybe too complex.

I've had a suggestion that we use the MegaCoin 'Gravity Well' -

Got the linux bug too :/

Error loading block database.
Do you want to rebuild the block database now?
bitcoind: db/version_set.cc:715: leveldb::VersionSet::~VersionSet(): Assertion `dummy_versions_.next_ == &dummy_versions_' failed.

Some more info about the linux crash problems.

When the database corruption occurs this also happens in the output:

terminate called after throwing an instance of 'boost::exception_detail::clone_impl >'
what(): boost::thread_resource_error: Resource temporarily unavailable

bitcoind has 0% cpu usage.

if you restart it, it goes back to 100%, but you get this:

error: {"code":-1,"message":"CDB() : can't open database file wallet.dat, error
-30973"}

if you replace the wallet with a backup, it starts again, but you get:

Error loading block database.
Do you want to rebuild the block database now?
bitcoind: db/version_set.cc:715: leveldb::VersionSet::~VersionSet(): Assertion `dummy_versions_.next_ == &dummy_versions_' failed.

after which it redownloads the chain and works again.

so it's some data corruption issue.

will send FreeTrade the logfile.

Thanks! Great work. I've tipped you 200 MMC from MCF funds. The MCF is now defunct, but has funds left over from MemoryCoin 1, so I'll run those funds down by distributing them to people doing useful stuff for the coin.

Thanks FreeTrade. Appreciate it.

FreeTrade,
Can you elaborate a little more on how to POW works in regards to the difficulty and 'solution' of 1968. I'm working to create a dedicated miner and pool software, and want to make sure I'm implementing it correctly. I've been digging through the source (it is the first time I've looked at a cryptocurrency in depth) and it is still not clear to me.

Thanks!

Here's the most straightforward explanation -
https://bitcointalksearch.org/topic/m.3945848

Best guide is the code, but if you have specific questions, I'll do my best to answer them - ask on that thread.

this is a weird block reward

I think that has to do with the officer voting/grant system? Maybe FreeTrade can shed some light on it.

Yep, those are the payments to the elected MemoryCoin officers -

I have a block explorer up for MemoryCoin. It can be found here:

Have a few more cosmetic things to add, but thought it would be useful for now.

If anyone wants to help support this project, I would greatly appreciate it. My MMC address is: MPdmnRRtYWhSp6cPY7LNaSrM429P8vdk56

I can understand the reasoning behind transferring transactions from MemoryCoin 1.0 over to this block chain, but I don't understand the ProtoShares thing. If I own 100 PTS, I can import that wallet.dat and I get 10 MMC? Why?

free trade developed the protoshare-qt too i guess he wants to support the III Team

Mortimer, restart the client with the lower block count. It helped here.

Restart worked, but that kinda sucks - I don't want to have to babysit these machines to make sure they're in sync Huh

Yeah, I have been babysitting all my PCs. Going to bed now, so when I wake up there will be probably nothing mined. :/ But so is life.
