A somewhat old one is better so it can download and verify the most recent blocks.<br/><br/>tcatm's 4-way SSE2 SHA-256 is in the file sha256.cpp and already uploaded a few revs ago.<br/><br/>I just now uploaded rev 134 which is the makefile.unix that enables building with it on Linux. If you build rev 134 on Linux now you'll get the -4way switch.<br/><br/>If you have problems building because of it, then edit makefile.unix and:<br/>- remove -DFOURWAYSSE2<br/>- remove obj/sha256.o from the end of these lines:<br/>bitcoin: $(OBJS) obj/ui.o obj/uibase.o obj/sha256.o<br/>bitcoind: $(OBJS:obj/%=obj/nogui/%) obj/sha256.o<br/><br/>The 0.3.10 linux build <i>will</i> have the -4way option when I build it.<br/><br/>Here are the patch downloads for Windows:<br/><br/><a href=\"http://www.bitcoin.org/download/bitcoin-0.3.10-win32-setup.exe\">http://www.bitcoin.org/download/bitcoin-0.3.10-win32-setup.exe</a><br/><a href=\"http://www.bitcoin.org/download/bitcoin-0.3.10-win32.zip\">http://www.bitcoin.org/download/bitcoin-0.3.10-win32.zip</a><br/><br/>SHA1 16645ec5fcdb35bc54bc7195309a1a81105242bb bitcoin-0.3.10-win32-setup.exe<br/>SHA1 4f35ad7711a38fe8c880c6c9beab430824c426d3 bitcoin-0.3.10-win32.zip<br/><br/>Steps:<br/>1) Shut down.<br/>2) Download knightmb's blk files and replace your blk0001.dat and blkindex.dat files.<br/><a href=\"http://knightmb.dyndns.org/files/bitcoin/blocks/\">http://knightmb.dyndns.org/files/bitcoin/blocks/</a><br/><a href=\"http://rapidshare.com/files/413168038/BitcoinBlocks.torrent\">http://rapidshare.com/files/413168038/BitcoinBlocks.torrent</a><br/>3) Upgrade to 0.3.10.<br/>4) It should start out with less than 74000 blocks and redownload the rest.<br/><br/>Or if you don't want to mess with downloading blk files, you can just do this:<br/><br/>1) Shut down.<br/>2) Delete (or move) blk*.dat<br/>3) Upgrade to 0.3.10.<br/>4) It redownloads all blocks, probably take about an hour.<br/><br/><br/></div>"
