Master Class On Hyperledger Besu

Introduce hyperledger besu, an enterprise grade java based ethereum client that runs on mainnet, private, or permission networks, with consensus algorithm, privacy features, smart contract support, and Remix integration.

Discover Hyperledger Besu features: a java-based, open-source platform that supports public and permissioned networks, on-chain and off-chain privacy with privacy groups, and easy deployment and monitoring with Prometheus.

Define the genesis file to start the network and set the genesis block with initial accounts, then examine Atash consensus and proof of authority for public and private networks.

Install the Besu binary distribution on macOS, verify the installation with the Besu command, and explore available options to run and configure the client.

Install the Besu client on Linux by downloading the binary distribution for version 20.10.4, unzip and rename it, then verify the binary to ensure a valid Besu setup.

Start the Besu client on the main network, review default options, and switch to the Robstown network with a separate data directory for its data.

Configure host and WebSocket settings and authentication credentials to interact with the Hyperledger Besu network, connect to the main and Robstown networks, and verify the chain via Postman.

Learn to configure Hyperledger Besu with a configuration file by defining key‑value options, setting the network and rpc, and understanding the command line–environment variable–config file priority.

Learn to start the hyperledger besu network locally by pulling the official docker image, launching a besu node, and connecting to the main network to access and sync data.

Launch the docker-based Besu node, expose rpc and discovery ports, and use a json-rpc call to fetch the network version and chain id from the local node.

Connect to the Robstown network using a docker-based Besu node, specify the network, adjust port 8546, and verify connection via the network version.

Generate public and private keys for four nodes to set up a private network on the Doca Manuel, using a config file and hyperspace tool to create network files.

Create a Docker Compose file for a Hyperledger Besu network with a bridge network and a /24 subnet, assign static IPs, and configure genesis and API exposure for three nodes.

Set up a private Hyperledger Besu network locally by creating a four-folder full-node structure with a data folder and a genesis file defining consensus and prefunded keys.

Set up a Hyperledger Besu network by starting bootnode and peer node with a genesis file and miner coinbase, enabling p2p and rpc, and verifying four interconnected nodes.

Learn to run a smart contract on a private Hyperledger Besu network using Remix and MetaMask, compiling and deploying, then store and retrieve values.

Set up a private local Hyperledger Besu network by configuring the repository, docker compose, genesis file, and base node, including private transactions, proxy key management, and Prometheus monitoring.

Spin up a docker-compose driven private Besu network, verify docker, pull images, and monitor health via a block explorer, Prometheus, and toughman dashboards; stop the network with the stop script.

Deploy a simple storage contract to a private Besu network using Remix and MetaMask, compile and deploy, then store and verify a value with proper chain id and gas settings.

Set up Orion by downloading and extracting the binary, then rename and verify the installation. Run the Orion binary to check the version on Mac and Linux.

Set up the database for all nodes and generate public and private keys for ordinals, including creating a password file and node directories on the local machine.

Create per-node configuration files for Orion nodes by copying a template, increment ports to avoid collisions, and specify public and private keys along with passport files for secure connectivity.

Set up and start besu and orion nodes, configure the genesis file and privacy settings, enable APIs, and verify synchronization across four connected nodes.

Create and deploy a simple smart contract using the privacy feature, detailing restore, get, and sender functions, and configure endpoints across nodes for testing.

Practice private transactions on Hyperledger Besu by deploying and invoking a smart contract, encoding inputs, and retrieving values through get value calls, with events confirming execution.

Create a private Hyperledger Besu network by cloning the repository, selecting the client, enabling private transactions, and reviewing the network files and node keys for privacy management.

Start the Hyperledger Besu network by running the setup script and initializing the privacy network. Verify blocks and peers, then query the network to interact with contracts.

Deploy a privacy-enabled smart contract on a private network, forming a privacy group between node one and node three to store values and read data across nodes.

Create a three-node private network using a genesis file for clear (proof-of-authority) consensus, update extra data, and set Nordlund addresses with pre-funded accounts; then spin up the network.

Create a permission config document for each node, define allowed accounts and allowed nodes, paste the genesis addresses, start the network, and propagate permissions to all nodes.

Configure the genesis and permissions, spin up a three-node Besu network, start each node with the provided commands, and verify the nodes via the browser.

Demonstrates practical account permissioning in Hyperledger Besu, including importing accounts from private keys, verifying permissions, removing and re-adding accounts, and executing inter-account transfers to update balances.

Enforce local permission by adding or removing accounts on node one and node two, verify with endpoint ports and per-node configuration files, and confirm transactions and balances across the network.
