Hyperledger Besu Networks
Deploy Hyperledger Besu Networks in Minutes
Launch enterprise-grade Hyperledger Besu networks with EVM compatibility, AI-powered smart contract development, and enterprise privacy features. Deploy public or private Ethereum-compatible networks instantly.
EVM Compatibility
Your Ethereum toolchain, on a private network
Besu is a full Ethereum client. Every tool your team already knows works without modification — the only difference is you control who participates.
Works unchanged on Besu
Zero code changes needed
// Same deployment script works on mainnet and Besu
const provider = new ethers.JsonRpcProvider(
"https://your-besu.chainlaunch.dev"
);
const factory = new ContractFactory(abi, bytecode, signer);
const contract = await factory.deploy();
await contract.waitForDeployment();Point JsonRpcProvider at your ChainLaunch Besu endpoint — nothing else changes.
What Besu adds over public Ethereum
- Deterministic finality — no reorgs, BFT consensus guarantees
- Permissioned participant list — only approved addresses can transact
- Zero gas costs — no ETH required for internal networks
- Private transactions via Tessera — payload never touches the main chain
- On-chain access control via smart-contract permissioning
- No public mempool — transactions stay inside your network
Migrate existing contracts, tests, and scripts as-is. Add permissioning and privacy on top.
How Besu Works
Deploy Enterprise Hyperledger Besu Networks Effortlessly

Enterprise Ethereum without the enterprise overhead
QBFT consensus, Tessera private transactions, and on-chain permissioning are what separate Besu from running a public Ethereum node. ChainLaunch configures and manages all three.
QBFT Consensus & Validator Management
QBFT (Quorum Byzantine Fault Tolerant) provides deterministic finality — once a block is committed, it never reverts. The validator set governs who produces blocks. Adding or removing a validator requires a proposal-and-vote round among existing validators, ensuring no single party can unilaterally change network control. ChainLaunch surfaces this as a UI-based governance flow.
- Tolerates up to ⌊(n−1)/3⌋ faulty validators — a 4-node network withstands 1 failure
- Add or remove validators via on-chain proposal and vote — no restart required
- Configurable block time and epoch length per network
- Clique (PoA) support for dev and test networks
- Validator health monitoring with per-node block-signing metrics
Tessera Private Transactions
Hyperledger Tessera is a private transaction manager that sits alongside each Besu node. When a transaction is marked private, the payload never touches the main chain — only a 512-byte hash does. The actual data is encrypted and sent directly to the specified Tessera nodes. Non-participants see the hash but cannot decrypt the content.
- Private transaction payload stored off-chain in Tessera, not on the main ledger
- Specify recipient Tessera nodes per transaction — fine-grained data sharing
- Privacy groups for repeated private interactions between a fixed set of parties
- EEA-compatible private transactions (priv_ JSON-RPC namespace)
- ChainLaunch provisions and wires Tessera to each Besu node automatically
EIP Support & On-chain Permissioning
Besu tracks Ethereum mainnet upgrades — EIP-1559 fee market, EIP-155 replay protection, Shanghai, Cancun — so your Solidity contracts compile and run identically on both networks. Permissioning is enforced at the node and account level through smart contracts deployed at reserved addresses, giving you auditable, on-chain access control.
- Full EIP compliance — ERC-20, ERC-721, ERC-1155, EIP-1559 all work out of the box
- Node permissioning: allowlist which enode URIs can connect
- Account permissioning: restrict which addresses can send transactions
- Smart-contract-based rules — permissioning is auditable on-chain
- JSON-RPC namespaces: eth_, net_, web3_, debug_, priv_, eea_
