Dustin Brody 13de015038 more 0.4.0 spec updates: renamings, continue Proposal updates, and note several more functions which were verified not to have changed in 0.4.0 (#163) 2019-03-11 09:33:24 -06:00
Jacek Sieka aec31b1126 Updates for finalizing chain! (#162) 
* set epoch_boundary_root - chain finalizes!
* fix slotStart to offset GENESIS_SLOT
* work around bug that will be fixed by
https://github.com/ethereum/eth2.0-specs/pull/732
* compile with debug info (there was a GC-related crash in C land)

spec version 0.4.0 update: shard_block_root -> crosslink_data_root; switch from validator.slashed_epoch -> validator.slashed approach; a couple assert -> doAssert; note fix for underflow-prone spec changes in checkAttestation; GENESIS_SLOT change from 2^63 to 2^32; refactor Proposer and ProposalSlashing structure; add signed_root; remove duplicate slashValidator (#159) 
* spec version 0.4.0 update: shard_block_root -> crosslink_data_root; switch from validator.slashed_epoch -> validator.slashed approach; a couple assert -> doAssert; note fix for underflow-prone spec changes in checkAttestation; GENESIS_SLOT change from 2^63 to 2^32; refactor Proposer and ProposalSlashing structure; add signed_root; remove duplicate slashValidator

* re-apply shard_block_root -> crosslink_data_root

* remove incorrect humaneSlotNum

* add (run-time only, alas) sanity check on signed_root

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
 2019-03-08 10:40:17 -06:00
Jacek Sieka 4d55cf8eea beacon node sim: various improvements (fixes #111) (#156) 
* allow running more or fewer validators
* use deterministic key generation for tests to avoid exhausting system
RNG
* update README with simulator docs
* write the data of each validator to separate file, instead of a big
chainstart.json (makes it easier to run different validator counts)

* 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

* avoid rescheduling epoch actions on block receipt (why?)
* make sure genesis block is created and used
* relax initial state sim parameters a bit
