Genesis Block Generator

WHAT IT DOES

Genesis Block Generator is a developer tool that simulates the creation of a genesis block for a new EVM-compatible blockchain. Enter a chain name, chain ID, initial supply, and an allocation address — the tool generates a simulated genesis block configuration in JSON format. It displays the genesis hash, chain name, chain ID, allocation address, supply, timestamp, nonce, and the full genesis JSON (including config, alloc, coinbase, difficulty, extraData, gasLimit, and other parameters). This is essential for developers planning new chains, testing genesis configurations, or learning about the structure of genesis blocks.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Enter the chain name (e.g., MyChain). Enter the chain ID — use a unique number for your chain (default 1337). Enter the initial supply in ETH (e.g., 1000000). Enter the allocation address — the address that will receive the initial supply. Click "Generate genesis block" to create the simulation. Results display the generation status, chain name, chain ID, genesis hash, and the full genesis JSON with all parameters. The output also shows the allocation address, supply, timestamp, and nonce. This is useful for understanding the structure of a genesis block and preparing for chain deployment.

TECHNICAL MECHANISM

The tool simulates genesis block generation using client-side logic. It generates a random genesis hash (64 hex characters), a random nonce (16 hex characters), and uses the current timestamp. The genesis JSON includes standard Ethereum configuration parameters: config (with chainId and hardfork blocks), alloc (with the allocation address and balance), coinbase (zero address), difficulty (0x400), extraData (empty), gasLimit (0x47e7c4), nonce, mixhash (zero), parentHash (zero), and timestamp. The balance is converted from ETH to Wei using ethers.utils.parseEther(). The tool does not actually create a real genesis block — the simulation is for demonstration and educational purposes. All operations are performed client-side — no data is stored or transmitted. The tool is read-only and does not sign any transactions.

WHAT IT CANNOT SEE

The tool cannot actually generate a real genesis block without a blockchain node implementation — the generation is a simulation. It cannot configure all genesis parameters (e.g., initial state, validator set) without user input — only basic parameters are included. It cannot validate the generated genesis file against network rules — the simulation assumes the configuration is valid. It cannot deploy a new chain from the genesis block — the tool does not include deployment functionality. It cannot manage chain configuration or upgrades — the simulation is static. It cannot generate genesis blocks for non-EVM chains. The tool is read-only and does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains for the wallet connection, but the genesis block simulation is chain-agnostic. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported for wallet connection but the simulation works for EVM genesis. The tool provides a simulation — for real genesis block generation, use a blockchain node implementation. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always verify genesis configurations with your blockchain implementation.
