verify blocks before storing in block pool / database (#158) 
* fix state db lookup typo
* fix randao reveal slot when proposing blocks
* only store blocks that can be applied to a state
* store state at every epoch boundary (yes, needs pruning!)
* split out state advancement function when there's no block
* default state sim to 0.9 attestation ratio

add initial block pool (#139) 
* implement in-memory block graph
* store tail block in database
* resolve unknown parents by syncing them from peers
* introduce concept of resolved blocks and attestations - those that
follow minimal protocol rules
* update state head lazily
* log more stuff
* shortHash -> shortLog
* start 9/10 beacon nodes by default, last can be started manually
* see also #134
* fix start.sh epoch length

Merge pull request #131 from status-im/state-replay 
initial state replay implementation
 2019-02-22 18:04:48 +02:00
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

initial state replay implementation 
* fix initial attestation pool on reordered attestations
* simplify db layer api
* load head block from database on startup, then load state
  * significantly changes database format
* move subscriptions to separate proc's
* implement block replay from historical state
* avoid rescheduling epoch actions on block receipt (why?)
* make sure genesis block is created and used
* relax initial state sim parameters a bit

Jacek Sieka 4670d6c98a naive attestation pool, in preparation of fork choice integration (#125) 
* move attestation pool to separate file
* combine attestations lazily when needed
* advance state when there's a gap while attesting
* compile beacon node with optimizations - it's tooo slow right now
* log when unable to keep up
