I tried this out, however it thrashes my drive constantly while download the blockchain.

Is it trying to flush things every block or something?  I would think since this data can just be refetched, it would make since to add buffering here.


It would be nice to have the dns proxy pick up the currently in use servers, instead of defaulting to telling Google every name we look up.



Does this fully implement the Proof of Stake coin mining of stake?


Would be nice to see a single key import from vanitygen for example.  Message signing would also
be nice.


How about a portable version, or at least let us place the data files elsewhere then %Appdata%.  Also
it would be nice to have the  blockchain data in the Public area instead of the Users so it can be shared.



Since it is commonly merge mined,  ixcoin support would be nice.


Ufasoft Coin every time gives unhandled exception error when closing Coin main window while downloading and synchronizing chains. I don't know is this caused by bug in program or weak hardware (Pentium4 2.8GHz 512RAM) that takes too long to close client because it trashes like mad due to 512 MB RAM.
It is a bug.
Long time closing because slow Sqlite transaction commit.
The next version will use another fast Database engine.

For now I recommend to use the program with only single enabled currency.

SQLightning may work as a drop in replacement.

BlockChain saved to the DB in normalized form. It results many file I/O operations.

Database directory can be changed by %COIN_APPDATA% environment variable.

SQLigtenging was tried as experimental DB backend. But we have found better solution (will be released soon).

Can't the many operations be combined into one transaction though?  It really is so bad with the thrashing that it is currently unusable for me. 

Guess I will see soon if the new db helps.

They are combined to one transaction for every block.
Even more: many transactions are combined to groups by nested transactions and SQLite used in Unsafe but Fast mode for BlockChain:
Code:
PRAGMA journal_mode=wal
PRAGMA synchronous=off

The only thing which improves SQLite performance is Page Cache Size. Probably we will release yet one version for SQLite with larger page cache before new DB Engine.

You may be interested to hear this: I was using minerd at work (shhh Smiley to get a little extra hash in my pool but the antivirus software went after it with a vengeance! Then I remembered that Coin has coin-miner with it and now I'm able to use all those extra cycles again Smiley.

What files are needed just to run the miner? (we aren't supposed to install apps on our work machines so it's best if it runs from a random directory). Thx!

openssl.dll

Thanks!  However, I found that coin-miner.exe,  miner.dll, usft_ext.dll, and coinutil.dll were all I needed to mine LTC (LP) by running 'coin-miner -h' until it quit complaining that a dll was missing.  I'm getting accepted shares, so it SEEMS to be working Smiley  Not keeping a wallet here, mind you, just exploiting the extra cpu cycles (gpu isn't compatable, an Intel 3000).  I use the wallet at home, though.

Thanks for the response!

I just saw that version .62 was posted in your files - will that version work on win 7 x64?

I really need a fix as i cannot access download the bitcoin blockchain without errors with the .61 version and therefore cannot access my coins to use them.

Thanks!

It is source code.
There is still one CRASH-bug present. We cannot release Windows Binary until it will be fixed.
