According to your README, params of init() like this.

casper_args = [
  EPOCH_LENGTH,
  WARM_UP_PERIOD,
  WITHDRAWAL_DELAY,
  DYNASTY_LOGOUT_DELAY,
  msg_hasher_address,
  purity_checker_address,
  BASE_INTEREST_FACTOR,
  BASE_PENALTY_FACTOR,
  MIN_DEPOSIT_SIZE
]

But in https://github.com/ethereum/casper/blob/master/casper/contracts/simple_casper.v.py#L130
like this.

def init(
        epoch_length: int128,
        warm_up_period: int128,
        withdrawal_delay: int128,
        dynasty_logout_delay: int128,
        msg_hasher: address,
        purity_checker: address,
        null_sender: address,
        base_interest_factor: decimal,
        base_penalty_factor: decimal,
        min_deposit_size: wei_value
        ):

I do not have confidence, but I think that
your README might be lack of a parameter of null_sender.

zaq1tomo · 2018-06-06T06:28:09Z

e.g.

null_sender_address = base_tester.get_accounts()[-2]

casper_args = [
  EPOCH_LENGTH,
  WARM_UP_PERIOD,
  WITHDRAWAL_DELAY,
  DYNASTY_LOGOUT_DELAY,
  msg_hasher_address,
  purity_checker_address,
  null_sender_address,
  BASE_INTEREST_FACTOR,
  BASE_PENALTY_FACTOR,
  MIN_DEPOSIT_SIZE
]

Glad to see y'all made it through the deploy!

I generally want to be less verbose in the readme. The high level details are more important than the python specific implementation.

Take a look at my notes and let me know if you ahve any questions.

+### Step 1: Imports


I want this to be way less system specific. Think, high level notes and a little bit of pseudocode. So we don't need to deal with imports

+
+### Step 2: Raise the Gas Limit
+
+```bash


Just note that the contract costs a lot of gas (can give a number) and that if they are deploying via a normal CREATE tx, then they need to make sure the block gas limit is high enough

README.md

+
+[Link to the web3.py documentation.](https://github.com/ethereum/web3.py)
+```bash
+base_tester = EthereumTester(PyEVMBackend())  ## instantiates the eth-test suite 


Just assume a web3 object exists. People will be deploying via all sorts of framekworks so the particulars here aren't important.

+
+### Step 4: Deploy Helper Contracts
+NOTE: In addition to the two helper contracts `msg_hasher` and `purity_checker` you also need to deploy the `rlp_decoder` Contract. On a production chain, an `rlp_decoder` contract is already deployed and vyper’s standard internal library knows it’s address and gives vyper contracts access to some functionality at that address.
+**When using a test chain, these helper contract must be deployed before the casper contract.**


Important to note that rlp_decoder must be deployed before compiling the casper contract.

+**When using a test chain, these helper contract must be deployed before the casper contract.**
+
+NOTE: these helper contracts are currently written in serpenat, so until they are converted to Vyper it is best to use the hardcoded transaction hex below. 


"These helper contracts can be deployed via the below pre-signed txs. Instructions for compiling and deploying via other methods will soon be available."

+### Step 6: Compiling and Deploying Casper
+```bash
+
+file = open(os.getcwd()+('/casper/contracts/simple_casper.v.py')) #this will change depending on where the casper contract is located relative to your current working directory


We should show how casper is compiled from the command line, rather than from python. Don't worry about showing how to open files.

vyper simple_casper.v.py vyper -f abi simple_casper.v.py

I am glad to receive your reply.

I understand your policy but your readme maybe incorrect.

zaq1tomo · 2018-06-07T00:12:44Z

README.md

+w3.eth.sendTransaction({'to': casper_address, 'value': 10**21})
+
+casper_contract = w3.eth.contract(address=casper_address, abi=casper_abi)
+casper_contract.functions.init(*casper_args).transact()


I think that it will not work with the latest version because casper_args is not correct.

Thank you for the hint. I will double check this issue.

zaq1tomo · 2018-06-07T00:15:22Z

I made a pull request to fix "casper_args".

@djrtwo I tried to incorporate your comments. Please review.

Hi @djrtwo I think this one might be with you for review, no? Hope you're doing well 🙂
