I suppose there is some protection from receiving massive amounts of fake blocks from 2009 before getting normal blockchain.
Attacker with 1 GPU could make many GB of early orphans.
Topic: Is blk0001.dat the same everywhere? (Read 725 times)
Each person who downloads the block chain from scratch should however get an identical (hash-wise) blk0001.dat from now on though, right?
That seems likely. I'm not sure that blocks are guaranteed to be ordered sequentially in blk0001.dat, though, or that extra data isn't added.

If correct, this would be because the network is making no effort to keep the orphaned blocks in circulation.

No. Orphan blocks (blocks not in the main chain) are also stored there, and each node is likely to have a different set of orphan blocks.
I felt the urge to open terminal write sha512sum blk0001.dat press return and post what came out:

I know answer is probably out there somewhere but I'm noob, so I'm gonna try to waste other peoples time.
