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

bb017a5dab Change the order of the messages in the version handshake. This fixes connections to BitCoin nodes beyond v0.30.20.2 which are "shy", that is, they do not announce their version on accepting a connection. The intent of that change is to make port scanning harder, though it is questionable whether this really is effective. 2011-03-25 20:41:26 +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.

57caa5503d Some changes to how block chain download is done: 
- Progress is now made available
- Fixes bug: can now wait for downloads of chains < 500 blocks
- Flesh out VersionMessage parsing, send BitCoinJ name in subVer field

f97cde4c34 Seek past garbage before the message header starts. It's unclear how this occurs but is probably an issue in the 
official implementation (which also does this seeking).
 
Print out some data from the ver message on connection.

Refuse to connect to nodes that don't provide the block chain.
