Per #1704 discussion, remove `on_time_slot`: the given `beacon_state`
should be transitioned.

Hsiao-Wei Wang 2d4788fe7d
Fix `verify_shard_block_message`
Add check for `block.beacon_parent_root` per Terence's suggestion

Update `get_shard_transition`

1. Disable verification: it will be fix in v-guide
2. Use `on_time_slot` to compute offset_slots

Jacek Sieka 56309342c0
Use `Bytes32` for `error_message`
`ErrorMessage.error_message` is a leftover from an older version of SSZ
that was able to encode unbounded lists. This is no longer the case -
all collection types now have a fixed upper bound on length.

In general, the `error_message`, just like the `graffitti` field, should
not be interpreted in any particular way except for debugging and vanity
- as such, using the same type, a `Bytes32`, seems reasonable.

An alternative would be `List[byte, 256]` which maybe could be
"reasonably backwards compatible" with whatever clients are are doing
now - depending on how they are dealing with this field type that no
longer exists in the SSZ spec :) It would however be the only place
where `List[uintN, N]` is used in the current spec.

As an exercise, this could be considered a security issue since it's
essentially unbounded and undefined behaviour.

Jacek Sieka 607e23949c
require blocks to be ordered consecutively in block range request
Per the spec, if I request range 5-10, it is permissible for a client to
answer with block 7, 9 - even if the blocks 5, 6 and 8 exist.

Because blocks 7 and 9 cannot be validated as they arrive in such a
request, it seems better to close this gap - this update adds the spec
language that forbids well-behaving clients from answering this way.

[squashed] shard chain updates wip
Fix wrong field names

Fix `build_attestation_data` and other PR feedback from Danny and
Terence

1. Rename `get_previous_slot` to `compute_previous_slot`
2. Break down `build_empty_block` into
`get_state_and_beacon_parent_root_at_slot`, use it in
`build_shard_block`
3. Set defult `slot` to `shard_state.slot + 1` in `build_shard_block`

Update `verify_shard_block_message`: check beacon_parent_root at fork
choice rule stage instead of state transition

Fix  `beacon-chain.md`

1. Fix typo `attestation.slot == state.slot` -> `attestation.data.slot == state.slot` in `is_winning_attestation`
2. Check `verify_shard_transition_false_positives` **after** `process_operations`
3. Fix `shard_attestations` filter in `process_crosslinks`: since attestations come from block, should use `attestation.data.slot + MIN_ATTESTATION_INCLUSION_DELAY == state.slot`
4. [TBD] Allow empty `light_client_signature` to make the tests pass
5. [TBD] Add `is_shard_attestation`, filter out empty `ShardTransition()`

Rework `test_process_crosslink`

Add basic phase 1 `test_blocks`

Add more test cases

Revert `is_shard_attestation` and fix test cases backward compatibility.

Remove `test_process_beacon_block_no_shard_transition` and consider it as invalid case.

2. Rename `compute_shard_transition_data` to `compute_shard_transition_digest`
3. Add `assert state.slot > PHASE_1_GENESIS_SLOT` just in case, may move it later

As per #1735 the check `if not len(indices) <= MAX_VALIDATORS_PER_COMMITTEE: return False` is redundant. As such this PR should be purely cosmetic.

simplify block range request description
There's room for ambiguity as to what `count` means - this clarifies
that it always relates to the slot, and not the number of blocks in the
response which allows clients to request ranges epoch by epoch (for
example) without worrying about overlaps caused by empty slots.

Tighten restriction on a "seen" attestation
Declares that only a verified block can stop an attestation from being propagated.

This achieves two things:

1. Ensures that clients don't need to scan invalid blocks for attestations and then modify their state based upon them.
1. Disallows "muting" attestations by sending around a junk block with that attestation in it.

Remove unneccessary clock disparity check
There is no need to mention clock disparity when comparing two static slot values (assuming the clock disparity is less than a slot, even then I don't think that's the intention).

Add fork version to topic
Gossipsub peers are separate from the ETH2 RPC protocol, and thus cannot
rely on the application-level `Status` negotiation to establish if
they're on the same network.

Segregating gossipsub topics by fork version decouples RPC from gossip
further and allows peers to more easily listen only to the traffic of
the network they're interested in, without further negotiation.
