Hi Philip,
The data file is here (130MB), zipping did not reduce the size much, so I
put the file
itself. https://www.dropbox.com/s/0rip4kydc5cn4dm/blk00976.dat?dl=0
Below is a code piece you can try.
regards,
---------------------------------------------------------------------------------------
import org.bitcoinj.core.*;
import org.bitcoinj.params.MainNetParams;
import org.bitcoinj.utils.BlockFileLoader;

import java.io.File;
import java.io.IOException;
import java.util.LinkedList;
import java.util.List;
import java.util.Locale;
public class ChainParserExperimental {
private static final Logger log =
LoggerFactory.getLogger(ChainParserExperimental.class);
public static void main(String [] args) throws IOException {
Context.getOrCreate(MainNetParams.get());
NetworkParameters np = new MainNetParams();
String blockDir = "D:\\Bitcoin\\blocks\\";
List<File> list = new LinkedList<File>();
for (int i = 970; true; i++) {
File file = new File(blockDir + String.format(Locale.US,
"blk%05d.dat", i));
if (!file.exists())
break;
//System.out.println(file.getAbsoluteFile().toString());
list.add(file);
}
BlockFileLoader bfl = new BlockFileLoader(np, list);
while(bfl.hasNext()){
System.out.println(bfl.next().getTime());
}
}
}
