Dustin Brody 1479bae22f implement distinct Epoch type and continue 0.4.0 spec update (#173) 
* implement distinct Epoch type
* update two more spec 0.4.0 markers, leaving just deposit processing

speed up epoch processing by caching shuffling results (#153) 
* speed up epoch processing by caching shuffling results

Dustin Brody 81d5becc7b Switch hash functions, prevent underflow & verify that shuffling works (#149) 
* prevent balance underflow, per spec implementation note

* verify that permutation shuffing works: add YAML dependency to be used for ingesting test cases; switch from blake2 to keccak256 to match EF test cases; remove inefficient naive-spec-version of shuffling algorithm now that protolambda's can be tested directly

Dustin Brody 8baab40ea6 much faster shuffling based on observations from https://github.com/protolambda/eth2-shuffle enough that it's not easy to get exact speedup numbers 2019-02-25 14:58:04 +00:00
Dustin Brody 2d52d5cbfe convert some asserts to doAsserts to keep them in release mode builds; rename get_initial_beacon_state to get_genesis_beacon_state to track spec; switch target spec version to 0.3.0; switch references to penalize_validator to slash_validator/slashValidator to track spec; make some function returns safer by omitting 'return' (#132)

* 2x shuffling speedup by hoisting pivot calculations per https://github.com/protolambda/eth2-shuffle

Dustin Brody 4574178836 epochs replace slots as main first-class entity; several mechanical renamings (ForkData -> Fork; .fork_data -> .fork; remove stub custody types/code; some type aliasing to keep slots and epochs more enforceably separate; fix test_state_transition.nim assumption that GENESIS_SLOT == 0 2019-01-28 19:22:22 -08:00

Dustin Brody eed9ea8f0a Spec updates (#64) 
* s/CrosslinkRecord/Crosslink/
