## Summary

### Fix (fb44d13)

Calling `network:generate` command then using new network config  does not compile  due to invalid genesis block type. This fix generates valid genesis block, writing string properties for `transaction.fee`, `block.totalFee` and `block.reward`.

### Feat (5b0fb68)

When I generate a new network config through `network:generate` command, my pre-mined tokens are locked into a wallet because generated passphrase is not shared by script. This improvement writes genesis wallet info into a file (`genesis-wallet.json` at core config path).
