codechain-helicopter's Issues

Integrate Travis CI

Calculate the nonce using pending parcels

Now the nonce obtained via getNonce does not consider pending parcel. So, after getting the pending parcel, we can calculate nonce again considering this.

Add README

Don't give reward to excluded accounts

Genesis account, host account(which provide rewards), faucet account should be excluded.

Add tests

Cannot sign a parcel
