Configure the Genesis Block
Understand how to create and configure the genesis block for your private Ethereum blockchain using a JSON file. Learn to set parameters like chain ID, consensus algorithm, gas limits, initial balances, and protocol transition blocks to establish your network's foundation.
We'll cover the following...
The genesis block is the first block in the blockchain and serves as the foundation of the network. Therefore, our blockchain also needs a genesis block. The Ethereum Mainnet genesis block can't be used because our blockchain is private and has a different consensus algorithm as well as different settings and features.
The genesis block of a private Ethereum network created using Geth can be configured using a JSON file (genesis.json). This file defines several parameters for the initial block, including the Ethereum protocol version, the initial difficulty level, the timestamp, and the account balances of the initial nodes on the network. It also specifies any custom rules or configurations that the ...
