slot -> epoch 2019-01-27 23:36:38 -06:00
vbuterin 656eae6f6a
Minimum slot number, simplify excessive anti-underflow logic 
Adds a minimum slot number large enough that integer underflows involving epochs and slots will not happen; simplifies some logic that was more complex to handle them.

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.....

BLS is the name of the signature scheme and BLS12-381 is the name of the

"BLS signature/pubkey" rather than a "BLS12-381 signature/pubkey".

Fixes bugs with description of deposit verification. 
1. The order of the `deposit_data` serialization does not match the current
Vyper contract. The description now matches that serialization.

2. The `deposit.merkle_tree_index` was not being used (at least explicitly) so
the text now reflects which inputs are to be used for which parameters in the
pseudocode spec that follows.

3. There seems to be a bug where we want the initial leaf to be the `hash` of
the `DepositData`, not the data itself. The text now reflects this requirement.

Ben Edgington 994a42e6b1 Add getter to Vyper contract for Merkle branches 
Returns the Merkle branch for the leaf at index `index`. This getter provides
an alternative way for beacon chain proposers to access the Merkle tree of
deposits rather than being Ethereum 1.0 light clients. The method can be
called on a trusted Ethereum 1.0 archive node at specific past block numbers
to retrieve the Merkle branch needed to register a validator.

Fixes bug with Merkle proof branch selection 
This code determines the order in which the next branch element and the
current value should be hashed to produce the parent node in the Merkle tree.

The existing code fails to verify branches constructed in the standard way.

This patch fixes the spec code so that it works properly by using an appropriate
parity calculation.

Example code here to illustrate it working:

Fix `verify_slashable_vote_data` 
The first field of `AttestationDataAndCustodyBit` should be an `AttestationData` object, not an `SlashableVoteData` object.

Update 0_beacon-chain.md 
* `processed_deposit_root` => `latest_deposit_root`
* `receipt_root` => `deposit_root`
* `receipt_tree` => `deposit_tree`
* Emphasize that deposits are Ethereum 1.0 deposits in text in various places
* `Eth1Deposit` => `Deposit` for consistency (Also happy sticking with `Eth1Deposit` and replacing `deposit_` with `eth1_deposit_` everywhere. This may be unnecessary since Ethereum 2.0 deposits can be distinguished with the `shard_` prefix, e.g. `ShardDeposit` and `shard_deposit`.)
* Clarify `withdrawal_credentials`.
* Clarify that multiple Ethereum 1.0 blocks can have the same deposit root.

Cleanups and fixes 
Cleanups

* (typo) Remove `get_new_validator_registry_delta_chain_tip` from table of contents
* (typo) Update "Routines for updating validator status" in table of contents
* Update `FAR_FUTURE_SLOT` from `2**63` to `2**64 - 1`
* Put more constants in "Initial values", homogenise
* Cleanup note formatting
* Remove `ZERO_BALANCE_VALIDATOR_TTL` logic (to be possibly reintroduced in phase 2).
* Cleanup `min_empty_validator_index`
* Rename `deposit` to `amount` in `process_deposit` and `DepositData`.
* (typo) Remove new line under `process_penalties_and_exits`
* (typo) "Status codes" => "Status flags" in the table of contents
* (typo) `(state.slot - EPOCH_LENGTH) % LATEST_RANDAO_MIXES_LENGTH` => Use `SEED_LOOKAHEAD` instead.
* Put `state.validator_registry_latest_change_slot = state.slot` in `update_validator_registry`.
* Use `GENESIS_SLOT` for `last_poc_change_slot=0` and `second_last_poc_change_slot=0`.

Bugfixes

* (typo) `validator_exit` => `exit.validator_index`
* Separate initial deposits and initial activations to avoid double activations
* Replace `proposer.status != EXITED_WITH_PENALTY` with `validator.penalized_slot > state.slot` in two different places.
* Replace `status == EXITED_WITH_PENALTY` with `validator.penalized_slot <= state.slot` (and validator active) in two different places.

Status code / slot reorganization 
* Added `activation_slot`, `exit_slot`, `penalized_slot`, `withdrawal_slot`, use these to determine if a validator is active
* Universal min activation/exit delay of 256 slots
* Min exit time of ~1 day, but penalization delays this to ~18 days
* Penalty calculation period of `[time penalized - 18 days, time penalized + 18 days]`; made the total penalties array fixed size and wraparound to make calculation more fine-grained
* Processes withdrawals in all epochs, not just dynasty-changing epochs
* Change `get_shuffling` function to take slot as argument

Not yet done:

* Removed `shard_committees` from the state
* Removed persistent committees from the state

Add placeholder array in state for VDFs 
Added `latest_vdf_outputs` in `state` initialised to an array of `ZERO_HASH` of length `LATEST_RANDAO_MIXES_LENGTH // EPOCH_LENGTH`. (There's one VDF output per epoch. The VDF input is the RANDAO mix at the epoch boundary.)

 Further changes to activate VDFs (in a future phase):

* Add a new beacon "VDF output and proof" transaction, e.g. with `MAX_VDF_OUTPUT_AND_PROOF := 1`.
* Adjust the `MAX_SEED_LOOKAHEAD` constant, e.g. to `2**4 * EPOCH_LENGTH`. (The `2**4` parameter is essentially `A_max`.)
* Add a `process_vdf_output_and_proof` helper function in the per-block processing:
    * Verify the VDF input hasn't already been processed (check the corresponding `state.latest_vdf_outputs` entry is not `ZERO_HASH`.)
    * Verify the proof is correct, i.e. matches the VDF input and output
    * Save the VDF output to `state.latest_vdf_outputs`
* In the per-epoch processing set the corresponding entry in `state.latest_vdf_outputs` to `ZERO_HASH`.
* Use a VDF output for the shuffling seed.

Changes to inactivity leak 
* Fixes parameters and makes clear that the inactivity leak is on a per-epoch basis (before the leak was technically 64 times too weak as it was calculated per-slot but applied per-epoch)
* Adds a `// 2` to the inactivity leak to compensate for it being applied twice
* Changes how it is calculated (no inactivity leak for not being part of the head, only basic leak)
* Separates out early inclusion incentives into a separate incentive component rather than being multiplicative with everything else

Remove MIN_VALIDATOR_REGISTRY_CHANGE_INTERVAL 
Slight simplification. Only substantive change is that if the validator registry stays constant, we don't reshuffle 3 epochs after the last reshuffling (ie. before the reshufflings happened after 1, 2, 3, 4, 8, 16... epochs, now it's just 1, 2, 4, 8, 16...)
