Are the AE tests still going on and is there any point me joining, is there much of a learning curve beyond setup of a client?

Building on previous posts.

The previous block is always read from the lastBlock ala getBaseTarget.

If a malicious person were to re-write the client at pushBlock so that previous block was offset by 1 at generation time so then verifyGenerationSignature would honour this previous block and skip the actual previous block, meaning that there would be a block with missing transactions making double spending possible.
