replace asserts in get_active_index_root and get_randao_mix with comment 2019-05-02 18:11:11 -06:00

Clean up verify_indexed_attestation 
Cosmetic changes:

* Add 4 lines of comments (now every statement has a comment)
* Avoid unnecessary `assert` (the end goal for me is for `assert`s to be exclusive to the operation processing helpers).
* Merge `return`s into one (increase readability, reduce verbosity)
* Use shorter-named `bit_0_indices` and `bit_1_indices` helper variables

Substantive change:

* Remove the condition that `len(0_indices) + len(1_indices) > 0`. This condition is redundant in the context of `process_attester_slashing` because of `slashed_any`. It is largely artificial in `process_attestation` where validators are incentivised to maximise new attestations.

Justin 8b316c6db4
Start moving state_transition.py to state transitition spec 
The state transition spec should be reasonably self-contained, limiting the amount of "magic" outside of it. This PR is a first step in this direction, specifically for operation processing.

Add 32-byte graffiti 
Add 32-byte of arbitrary "graffiti" data in beacon blocks, in a similar vein to `extraData` in Eth1. To be used in wonderful and unpredictable ways (permissionless innovation by block proposers).

Fix two effective_balance bugs
 2019-04-29 12:06:27 -06:00
vbuterin 77d7aa7630
Attestation committee refactor 
* Remove `get_crosslink_committees_at_slot` (that function's ugly man...)
* Make the "base" that everything works off instead be `get_crosslink_committee`
* Attestations store epoch, start shard and shard, no longer slot (slot can be calculated from the other three)
* Retaining start shard in attestations allows `get_attesting_indices` to peek much further back into the past, making it useful for slashings (Phase 1)
* Some two-layer-deep nested loops become one-layer-deep loops

Fix two effective_balance bugs 
* Initialisation bug: initial `effective_balance` be not greater than `MAX_EFFECTIVE_BALANCE`
* Hysteresis bug: do not prevent `effective_balance` to go from `MAX_EFFECTIVE_BALANCE - 1` to `MAX_EFFECTIVE_BALANCE`

Fix activation queue bug 
Fix bug [flagged by @NIC619 and @hwwhww](https://github.com/ethereum/eth2.0-specs/pull/850#issuecomment-485275575) whereby the `activation_epoch` of validators dequeued since the finalized epoch was overwritten.

Cosmetic changes:

1) Remove `activate_validator` (there is no overlap between genesis and non-genesis activations)
2) Improve comments related to activation queue

Disallow transfers 
As discussed in yesterday's call, temporarily disable transfers until the network is deemed stable enough. We can consider doing a "test-run hard fork" changing this constant prior to the phase 1 hard fork.

Simplify get_justification_and_finalization_deltas 
Cosmetic changes related to `get_justification_and_finalization_deltas`:

* Review naming of misc helper functions and variables
* Abstract away common logic and rework for readability
* Add `MAX_FINALITY_LOOKBACK` and `BASE_REWARDS_PER_EPOCH` constants
* Rescale `INACTIVITY_PENALTY_QUOTIENT`

Substantive changes:

* Make logic relative to `previous_epoch` throughout (as opposed to mixing `current_epoch` and `previous_epoch`)
* Replace inclusion delay bonus by an inclusion delay penalty

Remove serialization from consensus 
Consensus now only cares about Merkleisation (i.e. `hash_tree_root`), not about serialization (i.e. `serialize`). This simplifies consensus code by a few tens of lines, is conceptually cleaner, and is more future proof.

A corresponding change is required in the deposit contract.

Possible aesthetic rework to get_domain 
In general I dislike how domains, which should be an unobtrusive out-of-the-way thing that we don't think about much, are taking up so much space in code to express, to the point of them being the single thing preventing `bls_verify` from being expressed in one line of code. Here I reorder arguments and add a default, and make `bls_verify` a one-liner.

Not necessarily convinced that exactly this approach is the way to go, but IMO it's worth considering.

Re-added some penalization in case of failure to finalize 2019-03-21 15:13:13 -05:00
vbuterin d1d1b73fb1
Simplify justification and finalization accounting logic 
Much of the simplification is cosmetic. The following changes are substantive:

* Inactivity leak penalty specifically on missing the target, not both the target and the source
* Even outside of quadratic leak scenarios, slashing victims suffer offline penalties

Replace committee exponential backoff with max progress 
Removes the mechanism that only rotates committees if blocks have been finalized and every shard has been crosslinked or at exponentially decreasing intervals, and replaces it with a rule that shard committees can only progress a maximum of 64 epochs at a time to preserve the invariant that maximum possible work required per epoch for a validator is O(1).

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.
