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

vbuterin d5900836aa
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

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.

Add explicit assert to get_permutated_index
There is an implicit assert in `int_to_bytes4`, however I think it's rather hidden.

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.

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.

Removes the source of the Vyper contract from the spec.
This change allows for easier maintenance of the code and the spec by
uncoupling them. Before any edit to either document resulted in having to
synchronize the other. By adding a reference to the canonical repo for the code
we avoid having to maintain a duplicate copy here.

SSZ list Merkle hashing change
The current spec is arguably inconsistent, in that if a set of N values gets chunked into M chunks where M is not an exact power of 2, the chunks between M and next_power_of_2(M) are filled with SSZ_CHUNK_SIZE zero bytes each, but the last chunk is not padded, and could be arbitrarily short (eg. if the values are 4 bytes and there are 257 of them, then that gets serialized into eight chunks chunks where the first four are 64 values each, the fifth is 4 bytes corresponding to the last value, and the last three chunks are SSZ_CHUNK_SIZE zero bytes). This PR fills every chunk up to exactly SSZ_CHUNK_SIZE bytes for consistency.

Remove the unnecessary double backticks on 'validator' in docstring.
The usual convention is that we mark function parameters in docstrings with
double backticks. There is no (longer a) parameter called 'validator' so we
update the docstring to conform to the convention.

Ben Edgington fb75c6dd55 Fix to verify bitfields and aggregate signature.
In blockprocessing, `crosslink_committee` is not defined. This is a fix.

In Phase 0 this check is redundant since we've already asserted that the
custody bitfield is all zero, but it will matter in later phases.

Remove exit counts
* Simplify by removing `exit_epoch` in `BeaconState` and `Validator`. (Also less storage for full nodes.)
* Replace with `exit_epoch` when ordering validator with withdrawal. Slight loss of granularity, but that's actually a good thing because it reduces the opportunity for manipulation by proposers.

Cleanup attestation inclusion logic
* (Logic change) Introduce invariant that attestations can be included for `EPOCH_LENGTH`.
* Simplify presentation by related checks into a single line.
2019-01-30 06:32:44 -08:00
Justin f4798370aa
Attester slashing fixes
* Fix bug whereby `intersection` (replaced by `slashable_indices `) could be non-empty, but no validator gets penalized because they were all already penalized.
* Rename `SlashableVote` to `SlashableAttestation` (for consistency with `Attestation`, and to avoid having "Vote" be a synonym of "Attestation").
* Rename `slot_included` to `inclusion_slot` for consistency with the `_slot` (and `_epoch`) postfix convention
* Homogenise ordering of fields in `Attestation` and `SlashableAttestation` objects (one has an `aggregation_bitfield` instead of the other's `validator_indices`).
* Homogenise ordering of fields in `Attestation` and `PendingAttestation` objects (one has an `aggregate_signature` instead of the other's `inclusion_slot`).
* Light presentation cleanup

Remove placeholders
Remove all custody and VDF placeholders (56 lines less!). A few notes on the placeholder fields and logic:

* All placeholder fields were dummy fields that can easily be restored in the phase 1 hard fork.
* One special case to the above is `custody_bit_0_validator_indices` in `SlashableVoteData` which was renamed to `validator_indices`. Renaming it back is *not* a spec change because SSZ field names are [no longer part of the spec](a9328157a8 (diff-8d8fe480a35579c7be2f976d9b321216)).
* The placeholder logic was written using generalised functions (e.g. `bls_verify_multiple` vs `bls_verify`, and `indices(slashable_vote_data)` vs `slashable_vote_data.validator_indices`). This generality was unnecessary because it was not triggered when all custody bits were 0. This means we can simplify the logic without being inconsistent with phase 1.

Rationale:

* Keep phase 0 (likely far harder to deliver than phase 1) as clean as possible
* Focus on upgrade paths and incremental releases
* Custody is still under research—keep the design space open

BLS-based RANDAO and custody (friendly to decentralised pools)
Unlock decentralised pools using m-of-n threshold BLS signatures for both RANDAO and custody. We also simplify a bunch:

* Remove `randao_commitment` and `custody_commitment`
* Remove miscellaneous logic such as `repeat_hash`

(Side note: Dfinity seems to be working to reduce the communication complexity of BLS DKG (Distributed Key Generation) so validator pools should also benefit from that.)

Implement #459
Contents:

* Peg entries and exits to epoch boundaries
* Add a store of historical active index roots
* Mix it into the randomness
* Remove the delta hash chain

Note that the actual light client implementation is beyond the scope of the spec.

[Note to reviewers: verify that the invariant added in the PR is correct]

Question:

* Do we want to also only store epoch-boundary randao values? I don't think we use the epoch-intermediate ones anywhere.....
