* Change digests to SHA2-256 (from Keccak256)
* Fix sha256 digest initialization - pass shuffling test
* Add comments + remove old shuffling tests
* Remove stale tree hashing tests
* Small toOpenArray optim + notes on in-place hashing
* Revert "Revert "Update test repo""
This reverts commit f385467cd3.
* Revert "Revert "Fix SIGFPE on shuffling for 0""
This reverts commit 226d380f87.
* Revert "Revert "Implement shuffling test (pending typedesc and shuffling algo fix)""
This reverts commit 813cb6fbb8.
* withEth2hash templates now needs ctx.init()
* Use init-update-finish to avoid burnMem
* signed_root -> signing_root
* implement new process_deposit; update timing parameters to 0.6.1; update Deposit to 0.6.1 and remove DepositInput
* update get_active_validator_indices and get_epoch_committee_count to 0.6.1; rm get_current_epoch_committee_count, get_previous_epoch_committee_count, and get_next_epoch_committee_count; bump state_sim default validator count a bit more
* re-introduce 0.5.1-ish get_active_validator_indices, get_epoch_committee_count as scaffolding for still-0.5.1ish shuffling
* rm now-superceded shuffling cache (shuffling is only called from get_crosslinks), which was badly architected due to trying to exist in state; rm one more vestige of previous light-client regime (one more to go, from datatypes)
* fix wrong shuffling list size (active validator size, not validator size) to make consistent with 0.5.1 (will be inconsistent with testnet0); fix typo and change defaults in state_sim
* doAssert a couple of constant relationships necessary to avoid underflow; rm non-spec, unused helper function get_new_recent_block_roots
* refactor separate crosslink_committee_cache and winning_root_participants_cache(s) into StateData object; remove last vestige of previous shuffling cache
* separate out caching parts of StateData to new StateCache object
* 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
* 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'
* 2x shuffling speedup by hoisting pivot calculations per https://github.com/protolambda/eth2-shuffle
* s/CrosslinkRecord/Crosslink/
* {MIN,MAX}_DEPOSIT to {MIN,MAX}_DEPOSIT_AMOUNT; rm SHARD_PERSISTENT_COMMITTEE_CHANGE_PERIOD; per https://github.com/ethereum/eth2.0-specs/issues/378 and 35adc9c61a rm persistent_committees, persistent_committee_reassignments, and ShardReassignmentRecord
* complete switchover from status/ValidatorStatusCodes to status_flags/INITIATED_EXIT/WITHDRAWABLE validator representation
* more work on block processing
* fix some unsigned issues
* fix ssz issue when last chunk is not full
* work around empty const seq compiler bug
* XXX -> TODO
