[XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency

[Buffer Overflow]

I also run my primecoin daemons with the datadir in ram memory to reduce orphans. Every millisecond counts to get a solved block out to the network, don't want any messing about with slow hard drives.

I'm getting a lot of orphans (~1 per hour) so I've been comparing debug.log with blockchain records based on UTC time... In most cases I'm ~1 second late so peer lag is to blame. But a few cases have been within the second, so you're absolutely right that efficiency getting solved blocks out is key.

When running p2pool it is recommended that you don't have too many bitcoind connections.

There's a compromise here: the more connections, the faster your node will be notified of new blocks and avoid wasting work, the faster it can include transactions with fees in the coinbase and the faster it will propagate a P2Pool block minimizing chances it would become orphan.  Orphans will quickly rise if you have very few connections (they are the means to be notified of other shares after all).
But the less connections, the less bandwidth used and the lower the latency.

I know we aren't using p2pool but maybe this applies here as well. Too many connections increases chances of your found block getting propagated, but also increases latency. So you need to find a balance.

I've reduced my primecoind connections to 15 with maxconnections=15 command in primecoin.conf.

By the way, I have no proof this works or not. I've got no orphans though.

Okay, can we get instruction on how to extract coin from our DigitalOcean droplet.  It has been so long since I have had to do console/coding like this .

Sure. I do it this way:

• ssh into remote instance
• ./primecoind listtransactions –> copy the address mentioned in the output at "address"
• ./primecoind dumpprivkey {{paste copied address here}} –> copy the private key returned
• on your local computer holding the "master wallet" -> ./primecoind importprivkey {{paste copied private key here}}
• now address holding the minted coins appears in your local wallet

No need to send coins over the blockchain this way, immature coins can be imported immediately.

So does this basically merge the wallets, or do I need to worry about what I already have in the 'master wallet'?

It's kind of a manual merge. Technically you just add a new address to your existing "master wallet" just like you could with any other address, too. In our case, that address is the one your newly minted coins were credited to. (Minted coins are always credited to a new address internally.)

All other addresses in your "master wallet" will remain untouched as will your remote wallets.

After importing the privatekeys, I see the blocks still show in the original wallet. I guess both wallets think they own the blocks. So.. if I spend some of the coins in the block involved, do both wallets register the transaction?

If I find this confusing, how do I make the original wallet to forget the moved block (but not all the blocks) ? I looked it up but didn't find answer. Thanks.

You can manually edit the wallet to remove the key, but I don't recommend it.

Just ignore it.

has anybody tried to compile primecoind him/herself on linux (in my case Ubuntu 12.04)?

Yes, you need to install the "...-dev" packages as well because they contain the .h files.
primecoind works well (I need to git pull again to get newest version), but I wasn't able to build primecoin-qt.
Maybe later today...
