Zahary Karadjov a586087472 Stable network simulation 2019-01-09 10:45:33 +02:00
Zahary Karadjov 1c30214e9a Reach block 64 in the network simulation
* Slightly better logging
* Handling of incoming blocks and missing blocks
2019-01-07 14:59:52 +02:00
Zahary Karadjov 8f9a5441f1 More reliable network simulation
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.

* change comment style on fields and constants to make room for better
comments
* add BLSVerify and BLSAddPbkeys facades to insulate spec code from
milagro
