Ștefan Talpalaru 8f64ab6add start.sh: use native Windows paths on Mingw 2019-02-28 09:50:17 +02:00
Jacek Sieka 1d9c91d230
cleanups 
* add ancestor getter to db layer, and use
* remove head block call
* add trivial beacon chain db test

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

Zahary Karadjov a586087472 Stable network simulation 2019-01-09 10:45:33 +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.
