teor 3f5e2695e3 chain: Tweak the version and time test bounds 
Use MAX constants for the block header version and time arbitrary test
ranges. Reduces the block header time arbitrary test range from 2**32 to
2**32-1 (u32::MAX). (2**32 is an invalid time value, which gets
truncated to 0 during serialization.)

Also add some comments about DateTime conversions.

Part of #477.

teor 719aa75581 chain: Add a comment about transaction sizes 
We don't need to check transaction sizes yet, because we aren't
parsing or generating transactions outside of blocks.

Part of #483.

consensus: Add a checkpoint verifier stub (#502) 
consensus: Add a checkpoint verifier stub

This stub only verifies blocks whose hashes are in the checkpoint
list.

It doesn't have tests, chain child verifies to their ancestors, or
support checkpoint maximum height queries.

Part of #429.

Add serde bounds to zebra-chain structures. (#231) 2020-06-15 15:08:14 -07:00
teor 210e11a86d chain: Check the maximum block size when parsing 
The maximum block size is 2,000,000 bytes. This commit also limits the
maximum transaction size in parsed blocks. (See #484 for the
corresponding limit on mempool transactions.)

The proptests might test the maximum block size, but they are
randomised. So we also want to explicitly test large block sizes.
(See #482 for these test cases and tests.)

Part of #477.

teor 585fa7a1ae chain: Verify the solutionSize field in block headers 
Verify the value of the equihash solution size field in block headers.

This field isn't stored in the BlockHeader struct, so we need to verify
it at parse time.

Part of #477.
