668b176283 Add a DiskBlockStore and associated unit tests. This removes the need to download the block chain from scratch each time a program is started up. 2011-03-28 17:59:10 +00:00

65b80720bd Move the next header creation method out of BlockTest and into Block, as it is useful for other unit tests as well. 2011-03-27 22:32:17 +00:00

dbab159551 First part of block chain handling rework. 
- Store the block chain using a get/put interface keyed by hash, 
  so we can add disk storage later.
  
- Add unit tests for difficulty transitions. Move some stuff into 
  NetworkParameters to make that easier.
  
- Track the best chain using total work done. Inform the wallet
  when a re-org takes place. Wallet currently doesn't do anything
  with this beyond informing the event listeners.

With this patch we're getting closer to a correct SPV implementation.

5e2e48eb5a Add the start of unit tests covering chain splits/reorgs, along with supporting code. The tests don't pass yet so they are marked @Ignore. 2011-03-15 13:58:52 +00:00

4003eee3fe Add getters/setters and a solve method to the Block object. Use this in a new proof of work unit test. 
Introduce a unit test NetworkParameters that has very easy difficulty.
Correct some assertTrue(false) type checks to use fail() instead.
Make ALLOWED_TIME_DRIFT non-public until I have a good explanation in the javadocs of what it's for.
Simplify Block.equals
