* The bootstrap_nodes.txt file in the node's data dir is now optional
* Log more data on start-up
* Use the latest ENR APIs
* Fix simulation build errors
We no longer discriminate between ENR, MultiAddress or ENode
bootstrap records (all of them are remapped to ENodes).
The discovery loop will stochastically try to reconnect to
accidentally disconnected nodes.
* add interop launcher scripts
* stick validator_keygen into beacon_node
* fix lmd ghost slot number on missing block
* use mocked eth1data when producing blocks
* use bls public key method for withdrawal credentials
* fix deposit domain
* prefer lowercase for a bunch of toHex
* build simulation binary in data folder to avoid data types confusion
* 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
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).
* 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)
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
