Setup for Tutors

So your are tutor - poor soul :) Good news is, after you have managed to setup this environment the grading later will work almost instantly ;)

Create PoA node account and test account

$ PWFILE=./passwordfile DATADIR=./datadir/alice/ bash ./util/scripts/geth_account.sh new
[...]
Public address of the key:   0xe63419B7c0be62A6127923fb70C32A5ca1926a16
Path of the secret key file: datadir/alice/keystore/UTC--2020-11-12T09-53-29.399025746Z--e63419b7c0be62a6127923fb70c32a5ca1926a16
[...]

If you already have an account

If you already have an account/keyfile you want to use just copy it over and create the according folder structure:

$ mkdir -p ./datadir/alice/
$ cp -r $FROM_SOMEWHERE/keystore ./datadir/alice/

Parameterize node

Based on the generated key files, replace the addresses of the PoA node in the gen.py. Adapt genesis json file with account of alice our one (and only) PoA clique node.

$ cd setup/environment/
$ cd genesis_config/go-ethereum/berlin
$ vim gen.py
$ python gen.py

Initialize alice

$ cp setup/environment/genesis_config/go-ethereum/berlin/genesis.json datadir/alice/genesis.json
$ make init-smartenv-geth-alice

Run node and extract enode connection information

Then edit the Makefile and set the variable GETH_ALICE_ADDRESS based on the previously generated address which should be unlocked for the PoA node. Then you can run the PoA node alice.

$ make run-smartenv-geth-alice
$ RPCPORT=8545 bash ./util/scripts/geth_attach.sh
> admin.nodeInfo.enode
"enode://9d3297cebb326554af6e6d3146c19856b42a4e97f5a361bd51d8cdf66881ddc65ca54ba4082a2bcba236f1a18082ad3315fb2f5065c617dc7bead1d0c07b6f61@127.0.0.1:30303?discport=0"

Remember to change the IP:

enode://9d3297cebb326554af6e6d3146c19856b42a4e97f5a361bd51d8cdf66881ddc65ca54ba4082a2bcba236f1a18082ad3315fb2f5065c617dc7bead1d0c07b6f61@131.130.126.71:30303?discport=30303

Enter the node info as default in the Makefile as variable GETH_BOB_BOOTNODE and run bob as client:

$ make init-smartenv-geth-bob
$ make run-smartenv-geth-bob

Note: Remember to change the localhost IP (127.0.0.1) in this enode string to the actual IP of the remote server (or the docker container).

Try to connect to the server

Now you can try to connect to the server and execute the following steps from the main README:

  • ** 5) Connection to the Custom Testnet **
  • ** 6) Go through the Crash Course **

Setup the challenges

From here you can continue with the setup.ipynb to setup the challenges for the participants. Just start the web3py container and navigate to the setup.

$ make run-smartenv-web3py
