Configure the Blockchain
Create a blockchain on the P-Chain.
Before we launch our first blockchain, we need to configure it. The configuration file is a JSON file that contains all the parameters for the blockchain.
For now you can just take the defaults here and click the View Genesis JSON button.
Genesis Builder
Create a genesis file for your new blockchain.
Chain Parameters
Enter the basic parameters of your L1, such as the EVM chain ID.
Permissions
By design, blockchain networks are fully permissionless, allowing anyone to transact and deploy smart contracts. However, certain use cases require permissioning to control who can participate in transactions or deploy contracts. On Avalanche, permissioning is an optional feature for Layer 1 blockchains that may or may not be activated, depending on the network's needs.
Tokenomics
Tokenomics in Layer 1 blockchains on the Avalanche network are highly flexible, allowing developers to tailor economic models to their specific needs. Each L1 can define its own native token, specifying its initial allocation, distribution mechanism, and whether it should be mintable for ongoing issuance. This enables a wide range of economic designs, from fixed-supply tokens to inflationary models that support network sustainability.
Transaction Fees & Gas
In addition to the native token, you can also configure the transaction fees (also known as gas fees). This allows Avalanche L1s to define the desired or maximal throughput of the blockchain differently.
