It can be used to connect to the existing public Ethereum network a. Besu can be configured to perform as a full node that syncs to the blockchain, to an archive node, which contains the data of the blockchain but does not participate in adding new blocks. It can also be used to create a private blockchain network, compatible to the Ethereum Virtual Machine EVM , for customized blockchain applications.

Different Ethereum clients interoperate if they comply with the reference specification and the standardized communications protocols. As such, they can all be used to operate and interact with the same Ethereum network. Once it finishes, build Besu with the Gradle wrapper gradlew , omitting tests as follows:. Move to the expanded folder and display the Besu help to confirm that the installation is correct:.

You can use flags and subcommands to configure specific options for Besu. These flags and subcommands can also be stored in a configuration file , which sets the initial parameters for Besu. Using a configuration file is useful because it can be saved and reused later. Besu uses the TOML format for this configuration file. The following is a short working example:. If you are interested in seeing all the options available for the configuration file, or via the command line interface, see the Hyperledger Besu Command Line official documentation.

Perhaps the main advantage of Besu is that it can be used to create private blockchain networks. Each retailer would run their own node in this example, submitting transactions to the private blockchain when customers make purchases. The rewarded points would accrue to a customer address, allowing the customer to accrue and use points across brands or vendors.

Another use case would be to create a private EVM compatible blockchain for organizations looking to host blockchain infrastructure, allowing nodes to join the network provided they agree to certain conditions. For example, to comply with specific regulations or standards that may not be present on the Ethereum Mainnet. The LACChain project is an example of such a blockchain network. The project was specifically created to encourage the use of distributed ledger technology in Latin America and the Caribbean.

As of May , it has 50 organizations participating in the network, running 82 nodes. The first block in a blockchain is called the genesis block. In order to join or create any network, the data for the genesis block must be provided. The genesis file defines the data that is in the first block of a blockchain, as well as rules for the blockchain itself. If a new node or validator attempts to join the blockchain, it will use the genesis file as the starting point when recreating the history of the chain in order to synchronize with the existing network.

The genesis file for Ethereum Mainnet, along with the supported testnets, is included in Besu. When creating a private network, a new genesis file must be created. The genesis file is a JSON formatted file. It looks like the below:. In this specific example, the genesis file is for an IBFT 2. Once you have created your genesis file, you need to save it within the directory where your blockchain networks files will be kept.

Do not save it within any node or data folders, but rather at the top level. To start up your network using the genesis file, run the following command:. There are some common goals however. Specifically, increasing the cost of a blockchain over time is incompatible with many use cases, and many use cases need to ensure significant scalability is feasible.

The computing power to validate blocks is meant to remain constant over time, regardless of the blockchain size or the number of network participants. The constant power requirements include:. Off-chain processing is a mechanism that can improve scalability. Likewise, Sharding, a mechanism proposed for Ethereum 2. Implementations might implement data storage used for optional off-chain operations.

Persistent storage that is resistant to brute force attacks generally uses a "defense-in-depth" approach. For example, instead of relying on restricted access to protect plain text storage, an implementation can further protect the data by encrypting it with an Authenticated Encryption with Additional Data AEAD algorithm, such as one described in [[RFC]]. The consensus algorithms supported by implementations need to be properly documented to enable interoperability.

Consensus algorithm implementation should be modular and configurable. Enterprise Ethereum clients might support local key management allowing users to secure their private keys. Clients might also support secure interaction with an external key management system for key generation and secure key storage.

For example, implementations could securely interact with a Hardware Security Module HSM , a physical device to provide strong and secure key generation, key storage, and cryptographic processing for deployments where strong security is needed. Any caller can add any address as a parent of an authorizedUser. To authenticate an authorizedUser , the contract follows the parent links and checks that the corresponding child link is present.
