I decided to make this because i wanted a portable client, all you need to do is follow the readme Very simple.

Planing to add Encryption in later versions. - The best odds and quickest transactions of any BTC sportsbook

There are several different types of Bitcoin clients. Server-assisted clients like rely on centralized servers to do their network verification for them. Although the server can't steal the client's bitcoins directly, it can easily execute double-spending-style attacks against the client.

Can you give some more details as to what you made?

Also, how do we know we can trust this? A rar file containing executables but no source from a downloading site, I think most of the people here will be to paranoid to use this. And they're right, it might mail the wallet to you or something :p

Bitcoin Core developer [PGP] Warning: For most, coin loss is a larger risk than coin theft. A disk can die any time. Regularly back up your wallet through FileBackup Wallet to an external storage or the (encrypted!) cloud. Use a separate offline wallet for storing larger amounts.

Trusting strangers......its not always wise.

Id like some instructions and docs how this works on a
windows 7 64-bit machine with an AMD, etc.

And some source made available for those who know how to look at.

probably just trying to get the software out there as quick as possible.....

The .bat file is:

@echo off
"\files\bitcoin.exe" -datadir=.\Wallet

So basically it launches the Bitcoin client and tells it where to find the data/wallet files.

The bitcoin.exe included doesn't match filesize for the most current bitcoin.exe from the official site, it's about 3mb smaller.
There's a libeay32.dll in with the bitcoin.exe, which is an OpenSSL library, if bitcoin.exe normally needs access to OpenSSL, then I'd assume this is just included as a dependency, if not then I'd be suspicious.

Just my quick look :-P

The .bat file is all there's to it. The client included was not tampered with as I downloaded it, but actually v0.3.21 (ie. not the latest).

In general, be careful, and if you really feel the need to run a third-party-supplied bitcoin client then at least check it's hashes (see the READMEs in - unforntunately the latest release doesn't appear to be signed).

For future reference, hashes of a couple of bitcoin binaries (old and new) as I got them from Sourceforge:

I wonder whether or not it might be better to try to build a portable Bitcoin using the Portable Apps Platform instead of just batch files.

Also, if you are going to use batch files, it might be worth the effort to add a few fallback nodes to the command as well.  A lot of public computers have the ports for IRC blocked.
