12-12-2019(pm) Running DevNet Locally

Participants

git clone https://github.com/CasperLabs/CasperLabs.git

2. Install docker and docker compose

3. Pull the dev images from docker

docker pull casperlabs/node:dev
docker pull casperlabs/execution-engine:dev

4. Export CL_VERSION to dev

export CL_VERSION=dev

Update: due to version mismatches please either build the client or use the tarball.

Please verify that the version of node and client match each other! They don’t necessarily have to match this example.

6. Compile the contracts

Navigate to the execution-engine folder to build the example smart contracts.

7. Run CLarity locally so you can observe your local blockchain! From the /hack/docker folder run:

Docker tag: dev

To simplify the process, we are deploying from the faucet account (we can skip funding an account to pay for the deployment)

Title	Description	Notes

Title	Description	Notes
Verify pre-requisites	Check that everyone has managed to get through the setup.	See above
Set up a local 3 node network	Using the Docker hack, set up a local network	Verify that the network comes up for everyone. Reference: https://github.com/CasperLabs/CasperLabs/tree/dev/hack/docker First run Wait and let the system generate keys. Start the bootstrap: Start the other nodes Verify that the network is working by looking at the logs To remove old networks use:
Deploy counter-define Propose a block Deploy counter-call Propose a block	Here we will deploy a contract to the local network to install it. Then we will call the contract using a separate transaction.	Counter Define deployment & Proposal Counter Call deployment Keep track of the number of times counter-call is executed so we can verify the output of the query later.
Propose a block	Call the client to propose a block	Same as above.
Obtain the block hash	Obtain the block hash for use in the state query	Call the client to get the block hash (can also tail the logs and see the block in the network)
Perform a state query	Using the gRPC

The export needs to happen again if a new terminal is opened.
Make sure that you don’t have any old Docker containers floating around from old nodes.
Do not make a mistake when creating node-0 (Medha did node-o and it was problematic)
To add CLarity and GraphQL to the Docker network run:

It won’t be possible to fund accounts using CLarity, but it is possible to observe what the deploy errors are.

We ran into problems with payment. Root cause - there IS a version difference with the client that matters. This will be resolved when Node 0.10 releases. In the meantime, grab the tarball or build the client from dev.
