polish merge/beacon-chain.md ( #2472 )
...
Polish `merge/beacon-chain.md` with mostly non-substantive changes.
**Non-substantive changes**
* rename `MAX_EXECUTION_TRANSACTIONS` to `MAX_TRANSACTIONS_PER_PAYLOAD`
- rename "execution transaction" to just "transaction" as per discussion with Danny
* rename `compute_time_at_slot` to `compute_timestamp_at_slot`
- the function returns a Unix timestamp
- "timestamp" matches `execution_payload.timestamp`
* be explicit about `ExecutionEngine.execution_state` for clarity
* rename `ExecutionPayload.number` to `ExecutionPayload.block_number`
- more specific ("number" is pretty vague)
- consistent with `ExecutionPayload.block_hash`
* rename `new_block` to `on_payload`
- the `on_` prefix is consistent with other event handlers (e.g. see `on_tick`, `on_block`, `on_attestation` [here](https://github.com/ethereum/eth2.0-specs/blob/dev/specs/phase0/fork-choice.md#handlers ))
- the `_payload` suffix is more to the point given the function accepts an `execution_payload`
- avoids conflict with `on_block` which is already used in the fork choice
* rework the table of contents for consistency
* order `is_execution_enabled` after `is_transition_completed` and `is_transition_block`
- `is_execution_enabled` refers to `is_transition_completed` and `is_transition_block`
* rename "transition" to "merge"
- "transition" is a bit vague—we will have other transitions at future hard forks
- there is no need for two words to refer to the same concept
* add a bunch of inline comments, e.g. in `process_execution_payload`
* make the `process_execution_payload` signature consistent with the other `process_` functions in `process_block` which take as arguments `state` and `block.body`
* remove `TRANSITION_TOTAL_DIFFICULTY`
- to be put in `merge/fork-choice.md` where it is used
* various misc cleanups
**Substantive changes**
* reorder `ExecutionPayload` fields
- for consistency with yellow paper and Eth1
- same for `ExecutionPayloadHeader`
- added comments separating out the execution block header fields from the extra fields (cosmetic)

Modify sync committee logic and parameters to reduce variance
...
Sync committee rewards as currently implemented significantly increase variance in proposer rewards: https://github.com/ethereum/eth2.0-specs/issues/2448
For example, if there are 200000 validators (6.4m ETH staked), then during each 1/4-eek (~54 hour) period there is a chance of 512/200000 that a validator will get accepted into the sync committee, so on average that will happen once every 200000/512 * 1/4 = 97.6 eeks, or close to two years. The payout of this "lottery" is 1/8 of that, or ~12.2 eeks (a bit less than four months) of revenue. This is much more severe than block proposing (a chance of 1/200000 per slot, or a lottery worth ~0.38 eeks of revenue once every ~3.05 eeks).
This PR makes three changes to cut make the sync committee lottery less drastic and bring variance closer in line with what is available from block proposing:
* Reduce the `SYNC_REWARD_WEIGHT` from 8 to 2
* Add a penalty for not participating in the sync committee, so that despite the first change the total net reward for participating vs not participating is only cut down by 2x
* Reduce the sync committee period from 1/4 eek to 1/8 eek (~27 hours)
With these three factors combined, the lottery reduces to ~1.5 eeks of revenue, on average occurring every ~48 eeks. Validators who are maximally unlucky (ie. never become part of a sync committee) only lose ~3.12% of their rewards instead of ~12.5%.
The compromises that this approach makes are:
* In the extreme case where >50% of proposers are operating efficiently, being in a sync committee becomes a net burden. However, this should be extremely rare, and in such cases validators would likely be suffering inactivity leak penalties anyway.
* Incentive to participate in a sync committee decreased by 2x (but this is IMO an improvement; sync committees are _not_ as important as proposals and deserve to have lower rewards)
* Minimum data syncing needed to maintain a light client increases by 2x (from 24 kB per 54 hours to 24 kB per 27 hours). A burden for on-chain light clients, but still insignificant for others.
