You'll need the latest versions of nim-eth-p2p, nim-serialization
and nim-json-serialization.
Before starting the simulation script, make sure to delete any previous
json files from the simulation folder:
```
rm tests/simulation/*.json
tests/simulation/start.sh
```
This should survive the creation of few blocks before diying with a
block validation error.
* spec updates
* balances move out to separate seq
* bunch of placeholders for proof-of-custody / phase1
* fix inclusion distance adjustment
* modify state in-place in `updateState` (tests spent over 80% time
copying state! now it's down to 25-50)
* document several conditions and conversations
* some renames here and there to follow spec
* initial rough commit of a work/attestation pool
* add kludgy participation_bitfield handling, some error handling, and document future improvments from spec update #47
* rename addAttestation to add for Nim consistency
* spec updates
* random small updates
* ssz no longer sorts by field, fix enum serialization
* rewire block processing a little to avoid a few state copies
* add a state simulation tool that writes out jsons
* some minor renames
* fix some leftover block slot references (replaced by state slot)
* fix some more uint underflows
* update epoch calculations (reward et al)
* now works past 100 epochs at least with empty blocks (very slow)
* use repeat_hash from spec in randao
* add some logging to state processing
* export crypto string converters in spec insulation layer
* enable block signature verification
* ssz: add support for arrays, remove custom data type code
* correctly handle previous and new block
* add trivial block processing tests
* prefer iterative repeat_hash
* state transition mostly done
* handle most specials and slashings
* spec updates
* make several constants uint64 to help minimize casting
* document data type woes - will have to revisit these
* change comment style on fields and constants to make room for better
comments
* add BLSVerify and BLSAddPbkeys facades to insulate spec code from
milagro
* fix proof of possession type
* drop explicitly ordered container fields from ssz - there's an issue
open to sort this out before committing it to the spec
* 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
* first part of spec updating; some constants, structure changes, data type changes from int to uint
* Update beacon_chain/datatypes.nim
Co-Authored-By: tersec <tersec@users.noreply.github.com>
* signature-aggreg-in-block-processing
* Message is a Blake2 hash not simple concat
* Address comments:
- Range change in parent_hashes computation
- Slot not beind module Cycles anymore
- justified_slot part of the hash
Not addressed: using parent.slot_number instead of block.slot_number
