Hyperledger Besu

[ggwpez]

Discussed in  Node meeting 23.4.2020.

Description 
Try out Hyperledger Besu as Ethereum Client for go-perun.

Context 
go-perun already works with gnache-cli, geth, parity and Infura.
Besu will hopefully work out-of-the-Box too.

Acceptance criteria 
A complete walkthrough of the perun 2-party-payment protocol is possible.
All on-chain balances are updated accordingly.

Hints 

• Setup Besu either using a premade build or compile from source.
• Fund two addresses that will be used by Alice and Bob.
• Check out 297-payment-demo, open alice.yaml&bob.yaml and set:
  • chain url to the address of the Besu client.
  • secret keys to the funded accounts from above.
• Set Bob and Alice addresses in network.yaml
• Start up Bob and let him deploy the contracts.
• Set the addresses of the deployed contracts in alice.yaml and start Alice.
• Play throught the protocol of connecting/opening/sending/closing a channel.
• Verify on-chain balances.
