* 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
* track justified and head blocks correctly in presence of blank slots
* fix new block state root
* keep list of viable heads instead of walking children
* disable json bitfield deserializer (needs a corresponding serializer)
* fix handshake best & finalized root
* begin 0.6.0: new get_domain/increase_balance/reduce_balance, BeaconState.validator_balances -> BeaconState.balances, some renamed constants, transaction processing changes, SlashableAttestation field name changes, 0.6.0 get_beacon_proposer_index always uses given state's slot, update tests subrepo
* mark get_bitfield_bit/bls_verify_multiple/stat-list-lengths/is_active_validator/is_surround_vote/slot_to_epoch/int_to_bytes/etc as unchanged in 0.6.0; rm Eth1DataVote/maybe_reset_eth1_period and thus adjust expected tree hash test results
* mark verify_bitfield/bls_verify/deposit-contract/VoluntaryExit/PendingAttestation/Historicalbatch/Fork as 0.6.0; update DOMAIN_BEACON_BLOCK to DOMAIN_BEACON_PROPOSER
* update Crosslink to 0.6.0 (also requires tree hashing test result change, so isolate in individual commit)
* mark verify_merkle_branch/get_delayed_activation_exit_epoch/ProposerSlashing/Attestation/AttestationDataAndCustodyBit/hash/integer_squareroot/get_epoch_start_slot/is_double_vote/get_randao_mix/generate_seed as 0.6.0; update reward and penalty quotients; SlashableAttestation -> IndexedAttestation; rm get_fork_version; ATTESTATION_INCLUSION_REWARD_QUOTIENT -> PROPOSER_REWARD_QUOTIENT
* Load full state test + Add json-serialization for Bitfield
* Implement empty_block_transition test (but test is missing the end state)
* Use the provided empty block instead of mocking one
* Add failing block signing test
* Tests that can't be passed now are now "for information" + indent the "information"/hash given
* fix node.state being used unsafely across async callbacks (fixes#230)
* node.state -> node.stateCache
* fix attestation validation not to use asserts
* re-enable attestation pool tests
* prepare for resizing validator registry
* 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
* ssz: avoid memory allocations
* a bit fishy with the 32-item stack.. this should be a smallvector
* digest: avoid another burnmem
* avoid a few allocations by using iterator
* avoid crash on invalid block production (fixes#209)
* fetch blocks every second, roughly
* fix start.sh param order
* run beacon node sim at slower pace
this is the beginning of tracking block-slots more precisely, so we can
the justification epoch slot bug.
* avoid asyncDiscard (swallows assertions)
* fix attestation delay
* fix several state root cache bugs
* introduce workaround for genesis epoch spec issue
* On the testnet site, the first N instead of the last N validators
will be considered reserved for users
* The number of validators is consistently named `totalValidators`
in all commands
* Proper keys are generated by default in validator_keygen
* no need to pass prev_block_root when updating state
* some Slot fixes
* fix `hash_tree_root` for Slot, Epoch
* detect missing hash_tree_root type support
* remove some <0.5 state checks
* have regular slot tick, decide on work to do lazily
* use beacon clock instance that will eventually sync time
* skip work when falling behind
* add one more state cache for justified state (since that's used in
fork choice)
* remove old sync cruft
* single timer per slot, serializing block production and attestation
* ssz: update to 0.5.1:ish
* slightly fewer seq allocations
* still a lot of potential for optimization
* fixes#174
* ssz: avoid reallocating leaves (logN merkle impl)
* update processExits to 0.5.1
* mark process_deposit, get_empty_block as 0.5.1; update get_genesis_beacon_state to 0.5.1; implement processDeposits
* hotfix via https://github.com/ethereum/eth2.0-specs/pull/821
* rm gone-in-0.5.0 Proposal, verifyBlockSignature, and slot check which moved to spec function processBlockHeader
* mark get_attestation_participants and get_epoch_committee_count as 0.5.1; finish updating processAttestations to 0.5.1; add kludgy workaround for bug relating to get_winning_roots_etc using crosslink_data_root as index when we have that as ZERO_HASH for all leading to it confusing attesters on different shards; rm BeaconState.latest_attestations, which splits into previous_epoch_attestations and current_epoch_attestations
* Fix CI due to removed latest_attestations field
* add simple bitfield type (fixes#19)
* fix bit endianess to match spec
* consolidate attestation and block logging
* cruft cleanup
* run optimizer on tests, speeds up build
* begin refactoring 0.5.0 epoch transition at justification and finalization
* update processTransfers to 0.5.0 spec
* update get_crosslink_committees_at_slot to 0.5.0 except for noted workaround for pre-0.5.0 spec bug related to epoch boundary conditions, to be flipped in more coordinated way with other epoch processing changes
* mark ejection processing as 0.5.0
* 0.5.0 epoch update finalization
* rm BEACON_CHAIN_SHARD_NUMBER to complete updating miscellaneous constants to 0.5.0
* mark verify_slashable_attestation as 0.5.0
* update process_attester_slashing to 0.5.0
* update process_slashings(...) to 0.5.0 and mark process_exit_queue as 0.5.0
* refactor epoch processing by implementing 0.5.0's update_registry_and_shuffling_data(...)
With these changes, running a simulation is very close to running
an actual testnet. Some checks have been added in the client to
make sure you are not connecting to an incompatible network (e.g.
a network running with a different number of shards).
* begin 0.5.0 spec update: parent_root -> previous_block_root, BeaconState.justified_epoch -> BeaconState.current_justified_epoch, DOMAIN_PROPOSAL -> DOMAIN_BEACON_BLOCK, temporarily rename BeaconBlockHeader to BeaconBlockHeaderRLP to allow for gradual re-merging without disrupting RLP; mark a few unchanged functions and data types, implement get_temporary_block_header/get_empty_block/should_update_validator_registry/processBlockHeader/cacheState; update a few others
* a dozen or so more trivial mostly comment changes, finding more unchanged parts of 0.5.0
* several more trivial changes; goal is to reduce noise around the upcoming substantial changes (epoch processing, etc)
* remove some redundant state updates
* when attesting late, use correct state / head
* don't send out obsolete attestations
* don't propose obsolete blocks
* remove some more resundant state updates :)
* simplify block logging (experimental)
* document fork choice division
* fix some Slot / Epoch conversion warnings
* keep track of a finalized block
* keep track of all justified blocks
* use naive spec version of LMD ghost
* cache slot number and a few more things in BlockRef
* keep track of the latest vote of each validator
* depend less on the state of node.state (it's a cache, effectively)
