First pass cleanup of bls_verify.md 
Misc cleanups:

* (typo) `highflag` => `highflag1`
* (typo) `lowflag = x = 0` => `lowflag == x == 0`
* Add structure and table of contents
* Describe more notation in words (e.g. `i`)
* Make sure flags are 1-bit
* Clarify and polish presentation

Example notation cleanups:

* `G1` => `id_G1` (to avoid confusing with the group G1)
* `field_modulus` => `q` (avoid using two names for same thing)
* `BLSVerify` => `bls_verify` (respect notation for functions in main document)
* `sig` => `signature` (avoid abbreviations as in main document)

TODO:

* Potentially describe `FQ2`, `b2`, `is_on_curve`, `multiply` in words
* Make the naming changes around `bls_verify` in the main document
* Fix any bugs introduced by the cleanup
 2018-12-09 14:21:34 +00:00
vbuterin 70836ecd1c Clarify why it's called INVERSE_SQRT_E_DROP_TIME (#261) 
* (cleanup) Rename `SQRT_E_DROP_TIME` to `INVERSE_SQRT_E_DROP_TIME` to reflect `1/sqrt(e)`
* (cleanup) Justify why it's called INVERSE_SQRT_E_DROP_TIME
* (cleanup) Polish and simplify presentation
* (bug fix) Fixed 2**34 value
* (bug fix) Replace epochs with slots to make the calculations work

Casper cleanups and bug fixes 
* (cleanup) `SpecialAttestationData` => `CasperVotes`
* (cleanup) `vote_1`, `vote_2` => `votes_1`, `votes_2`
* (bug fix) Place a bound on the number of votes with `MAX_CASPER_VOTES`
* (bug fix) Supply `state` when calling `verify_casper_votes`

Bug fixes and cleanups around exit_validator 
Cleanups

* Use `state.slot` over `current_slot`.
* Specify `new_status`
* Segregate ejection processing

Bug fixes:

* Put ejections at the end of the per-slot processing (TODO: per-slot processing should come *after* per-epoch processing)
* Immediately exit ejections
* Include `ACTIVE_PENDING_EXIT` as an active state
* Renamed two `State` to `BeaconState`

Handle activations and exits separately for balance churn (#230) 
This change is to avoid deposits from fully consuming the allowable balance churn, preventing exits from being processed. And vice versa with deposits/exits swapped.

A bunch of cleanups and bug fixes were made along the way.

Cleanups pt. 1 (#185) 
Many cleanups in this monster commit! Two warnings:

1) More significant cleanups will be coming soon™.
2) While several bugs were fixed in this cleanup, some will undoubtedly have been introduced (thanks to the three reviewers!). In particular, the logic around validator statuses is known to be broken.
