Reading & Parsing Blockchain DAT files

Reading & Parsing Blockchain DAT files

I'm working on some code that reads the DAT files in the Blockchain, and I was trying to use bitcoinj because it seemed fairly straightforward. However, I can't seem to get it to actually read the blocks within the DAT file. I've tried many different versions and have made no significant progress.

I'm feeling like this should be fairly straightforward, and I'm just missing something simple here. To be clear, I'm not trying to write to the Blockchain, just read the DAT files.

Thanks!

Here is a code snippet.

NetworkParameters np = new MainNetParams();
Context c = new Context( np );
Context.getOrCreate(MainNetParams.get());
List<File> blockChainFiles = new ArrayList<>();
blockChainFiles.add( new File( "blk00000.dat" ) );
BlockFileLoader bfl = new BlockFileLoader(np, blockChainFiles);

int blockNum = 0; // Iterate over the blocks in the dataset. for (Block block : bfl) { ...

This code produces the following error:

Exception in thread "main" java.lang.IllegalStateException: Context does not match implicit network params: [email protected] vs [email protected]
at org.bitcoinj.core.Context.getOrCreate(Context.java:147)
at testBitcoin.main(testBitcoin.java:20)
