Monad: The Most Performant EVM-Compatible Layer 1 Blockchain

·

The Monad protocol delivers full Ethereum Virtual Machine (EVM) compatibility with breakthrough performance, true decentralization, production-grade security, and exceptional throughput. It effectively addresses the blockchain trilemma, offering a seamless experience for developers and users.

Understanding Monad's Core Advantages

Monad represents a new paradigm in blockchain technology. It is rebuilt from the ground up to be the world's most efficient chain while maintaining 100% EVM compatibility.

Unmatched Performance Metrics

Monad achieves remarkable scalability through several key innovations:

Full EVM Compatibility

With Monad, developers can reuse the entire existing EVM ecosystem. This includes applications, libraries, addresses, and applied cryptography research, all without requiring any code changes to existing Solidity smart contracts.

Path to Scalable Decentralization

Monad's low hardware requirements allow consumer-grade hardware to run nodes sufficiently. This significantly reduces the barrier to entry for node operators, creating a clear path to true, scalable decentralization.

Technical Innovations Powering Monad

Monad is a comprehensive redesign of both the consensus and execution systems of Ethereum that preserves full compatibility for EVM smart contracts.

Optimistic Parallel Execution

Monad employs optimistic parallel execution, processing transactions simultaneously before previous ones are completed. Results are then committed in their original order and rigorously checked against the current state to ensure absolute accuracy and maintain consistency.

MonadDB: A Purpose-Built Database

MonadDB is a custom database engineered specifically for storing blockchain state. It utilizes a Patricia Trie data structure, operating both on-disk and in-memory. This design drastically reduces hardware requirements by allowing most of the state to be stored on SSDs instead of RAM.

Asynchronous Execution and Consensus

Execution is decoupled from consensus within Monad's architecture. This innovation allows a single-shard blockchain to scale effectively to millions of users without compromising on performance or security.

High-Performance PoS Consensus

Monad utilizes a high-performance Proof-of-Stake (PoS) consensus mechanism. This is integrated with MonadDB and achieves 1-second block times, ensuring both speed and network integrity.

Ecosystem and Builder Support

Monad Labs is committed to fostering a thriving ecosystem by supporting the visionaries and creators who will shape the future of Web3.

Monad Madness Global Competition

Monad Madness is a global pitch competition for ambitious founders building within the Monad ecosystem. It features a $1 million prize pool, judges from top venture capital firms, and $60 million earmarked for potential investment in Monad ecosystem teams.

EVM/accathon at ETHDenver 2025

This premier hackathon is focused on building the future of the EVM. It is not an average event; applications are scrutinized, and a limited number of submissions are accepted to ensure quality and provide intense support.

Mach Accelerator Program

Mach is a dedicated accelerator program designed to help new builders launch their startups. It provides the essential tools, mentorship, and resources needed to turn ambitious ideas into successful ventures.

The program includes:

Frequently Asked Questions

Is Monad truly 100% EVM-compatible without code changes?
Yes, Monad is 100% EVM compatible at the bytecode level. Smart contracts from Ethereum mainnet or other fully EVM-compatible networks will work immediately without any modifications. You can simply deploy your existing contracts to benefit from drastically reduced costs and enhanced performance.

How is MonadDB different from other databases?
MonadDB is the first database purpose-built for the EVM. It is optimized to store data in a Merkle Patricia Trie (MPT), which is essential for succinct verification of blockchain data. It uses advanced Linux kernel technology to support parallel state access, reducing overhead. Standard off-the-shelf databases are often inefficient for MPT data, hindering scalability.

In what language is the Monad client developed?
The Monad client uses a modular architecture. The consensus client is written in Rust, chosen for its memory safety and low-level optimization capabilities. The execution client is written in C/C++, leveraging these well-established languages for developing robust, system-critical code.

Why is the Monad blockchain developed as an L1?
Monad is a full-stack solution that provides developers access to a highly composable ecosystem without compromising on real-time censorship resistance. While L2s offer data compression solutions, Monad is a scalable base layer for the EVM itself, offering the best of both worlds: high composability and strong security guarantees.

What are the hardware requirements for running a Monad node?
A key innovation of Monad is its low hardware requirements. By using MonadDB to store state data efficiently on SSDs, the need for expensive RAM is significantly reduced. This allows nodes to run on consumer-grade hardware, promoting greater decentralization.

How does optimistic parallel execution work?
Transactions are executed in parallel speculatively. The system then checks the results against the canonical transaction order to ensure correctness. This approach maximizes hardware utilization and throughput while maintaining the same deterministic outcomes as serial execution.
