Move to SHA256
SHA256 is de facto blockchain standard. Standardisation of the hash function is a prerequisite for [full standardisation of BLS12-381 signatures](https://github.com/ethereum/eth2.0-specs/issues/605). Blockchain projects are likely to provide a cheap SHA256 opcods/precompile, and unlikely to provide a Keccak256 equivelent. (Even WASM-enabled blockchains are likely to provide a SHA256 opcode/precompile since WASM does *not* natively support optimised SHA256 CPU instructions.) With Ethereum 2.0 embracing SHA256 the wider industry is more likely to converge towards a unified cross-blockchain communication scheme via Merkle receipts.

There are no security blockers with SHA256 (see comments by Dan Boneh [here](https://github.com/ethereum/eth2.0-specs/issues/612#issuecomment-470452562)).

Change get_shuffling to compute_committee
See #729 and #774 

The behavior now is that the first committee will consist of `get_permuted_index(0..n-1)`, the second committee `get_permuted_index(n....2n-1)`, etc.

Fair proposer selection probability
Note that as a side effect, proposer selection becomes less predictable, but I don't feel like this is a large downside.

Fair proposer sampling
I think we want `first_committee[epoch % len(first_committee)]` as opposed to `first_committee[slot % len(first_committee)]`. The reason is that if the shuffling happens infrequently and `len(first_committee)` is a multiple of `SLOTS_PER_EPOCH` then the proposers will not be sampled fairly.

Taking this logic further, we may want to avoiding always picking the proposer from `first_committee`, e.g.:

```
    validators_at_slot = []
    for crosslink_committee, _ in get_crosslink_committees_at_slot(state, slot, registry_change):
        validators_at_slot.append(crosslink_committee)

    return validators_at_slot[epoch % len(validators_at_slot)]
```

Proof of custody game, take 2 (#682)
* Proof of custody game, take 2

Unfortunately not simpler than before, but moves challenges outside of the validator records and so keeps validator records constant-size.

* Removed unneeded challenge codes

* Formatting fixes

Convert transaction descriptions from English to python code
Only a change of presentation, does not make any substantive changes.

Does NOT handle Deposit transactions because that is a special case for which I recommend a deeper change (will do this in another PR soon).

Rewrite SSZ spec
* Implement tuples and a chunk-size reduction to 32 bytes (see #665 and #679)
* Simplify presentation where appropriate. For example, deserialisation is implicit from serialisation (similar to `bls_sign` being implicit from `bls_verify`) and is left as an implementation exercise.
* Dramatically reduce spec size and hopefully improve readability.

Updated phase 1: branch and early subkey reveal challenges (#587)
* Updated phase 1: branch challenges

* Removed unnecessary line

* Added early subkey reveal slashing

* Revealing during the active period is still revealing early

* Added....

* Machinery for publishing old subkeys
* Inability to withdraw until you published all subkeys
* After a validator exits the queue there's still a minimum 1-day delay before they can withdraw (in the future this delay will be used as an opportunity to start a PoC challenge game)

* Update 1_shard-data-chains.md

* formatting

* minor edits

* Added masking scheme for reveals

Secure under the aggregate extraction infeasibility assumption described on pages 11-12 of https://crypto.stanford.edu/~dabo/pubs/papers/aggreg.pdf

* Added rewards going to challengers

* Add ToC and reorg the constant tables

* Remove tags

* fix constant formatting

* normalize domain constants in phase 1

* Update 1_shard-data-chains.md

* Update 1_shard-data-chains.md

* Update 1_shard-data-chains.md

Cayman 5fbbb4f181 Clarify merkle_root documentation (#646)
This function is used to get the merkle root of some block roots which are themselves hashes, so the leaves do not need to be rehashed.
Unfortunately, it's easy to assume that a merkle_root function would hash its leaves, so it should be clarified.

vbuterin 59ade930d6 Signature hashing proposal (#625)
If this is accepted, then we can replace all uses of signing in the protocol, which are currently done in a relatively inconsistent way (see proposer signatures, attester signatures, shard proposer signatures, exit message signatures.....) could be unified.

vbuterin eadfa20b99 Bring forward changes to withdrawability from phase 1 (#615)
* Bring forward changes to withdrawability from phase 1

* The `WITHDRAWABLE` flag is removed; instead, a validator's withdrawability is determined through the `withdrawable_epoch` field (renamed and re-purposed from `withdrawal_epoch` which was not used)
* When a validator passes through the withdrawal queue, the `prepare_validator_for_withdrawal` function does not let them withdraw immediately; instead, they have to wait `MIN_VALIDATOR_WITHDRAWAL_EPOCHS`. This extra minimum delay serves no value in phase 0, but is crucial for phase 1 as the period between a validator passing through the queue and the validator being eligible to withdraw is where proof of custody challenges can come in; adding it in phase 0 is only half a line of code so easier to add it now.
* If a validator is penalized, they are no longer subject to the exit queue; instead, their `withdrawable_epoch` is set `LATEST_PENALIZED_EXIT_LENGTH` into the future and this is used to determine when the validator can withdraw
* Changes the eligibility condition for a transfer to use the `withdrawable_epoch`

Merkleise SSZ container elements (#595)
Reasons to use `merkle_hash` instead of  `hash` for containers:

1) **Smaller witnesses**: `BeaconState` is a somewhat wide container (26 fields as of now, likely 30+ in phase 2). With concatenation and plain concatenation the size of the Merkle witnesses for the top level are ~32 bytes per field element.
2) **Faster incremental hashing**
3) **Consistency**: Consistent with `merkle_hash` for lists/vectors.

vbuterin abed5ffdae Updated phase 1: fork choice rule (#586)
Adds the crosslink committee to the fork choice rule. This is useful because it means that even if a proposal committee is byzantine and attempts to prevent a crosslink via a "balance attack" (alternating between chain A and chain B being the canonical chain), the crosslink committee can force the equilibrium to flip to one side or the other.

vbuterin 086df84bdc
Attestation data contains latest crosslink, not just latest crosslink data
The reason to do this is that it makes it calculable from inside an attestation how many epochs the attestation spans over, which is needed for proof of custody reasons. It's a relatively small change and so arguably easier to do now than to do as a patch in phase 1.

Note that this changes the meaning of latest_crosslink.epoch, from the epoch when the latest crosslink was included to the epoch that the latest crosslink was for. This affects the line:

* `state.latest_crosslinks[shard].epoch > state.validator_registry_update_epoch` for every shard number `shard` in `[(state.current_epoch_start_shard + i) % SHARD_COUNT for i in range(get_current_epoch_committee_count(state))]` (that is, for every shard in the current committees)

But this may actually make it _more_ correct, as it means that in the case where >512 shards are processed per epoch, and so a committee from the previous epoch could get finalized in the current epoch, that would no longer count toward every shard having received a "new" crosslink.
