Monad: Speed Without Sacrifice
Blockchains face a familiar trade-off: speed, cost, and decentralization - you usually get two of three. Ethereum prioritized security and decentralization but struggles with speed and fees when demand spikes. Monad is an ambitious Layer 1 that aims to keep Ethereum’s developer-friendly ecosystem while dramatically improving throughput and lowering per-transaction cost. This article explains what Monad changes, why it matters, and the numbers you should know - in plain language.
Key Highlights
- Target throughput: up to 10,000 transactions per second (TPS).
- Block and finality goals: sub-second block times (targets around 0.4–1 second).
- Early testnet performance: testnet observations showed hundreds of TPS under normal load and spikes into the low thousands during testing.
- Validator activity: initial testnets ran with tens-to-hundreds of validators as the network matured.
- Token supply: a large native supply has been announced for ecosystem purposes.
These figures show Monad’s ambition: it wants to run many more transactions than Ethereum while staying compatible with Ethereum tooling.
Why EVM compatibility matters
Monad is EVM-bytecode compatible. In practical terms, that means contracts compiled for Ethereum should run on Monad without rewriting. Developers can keep using Solidity, Hardhat, MetaMask, and the rest of the familiar toolset. For projects and teams, that reduces migration friction and accelerates adoption - you don’t have to learn an entirely new stack to take advantage of a faster chain.
Two core technical ideas
1. Parallel execution
Most chains, including Ethereum, execute transactions one after the other. Monad analyzes dependencies between transactions and executes independent ones in parallel - like opening multiple checkout counters instead of servicing a single long line. Because many transactions don’t touch the same state, parallel execution dramatically increases throughput and resource efficiency.
2. Asynchronous execution
This is the more subtle but crucial change. On Ethereum, nodes usually execute transactions and then reach consensus on the resulting state. Monad flips part of that flow: validators first agree on which transactions will be in a block (consensus) and only afterwards execute those transactions - often in parallel. In short: consensus happens first, execution happens later.
That separation allows blocks to be agreed upon quickly and gives the network time to schedule and run execution efficiently. It reduces the time nodes spend waiting and improves finality speed without sacrificing deterministic outcomes: because the execution environment is deterministic, the final state is still predictable even when execution happens after consensus.
How fees and balances change
Since Monad reaches consensus before executing, validators sometimes include transactions without yet knowing the exact execution cost. To handle this, Monad’s fee model includes:
- Base fee - a network minimum similar to Ethereum’s base fee.
- Priority fee - an optional tip to make a transaction more attractive for inclusion.
- Inclusion fee (reservation cost) - an extra charge taken when a transaction is accepted into consensus, covering the uncertainty about execution cost.
To avoid the problem of a transaction being included but then failing during execution for lack of gas, Monad separates funds into two balances per account: a consensus balance (used to pay inclusion costs) and an execution balance (used when the transaction actually runs). This split reduces the risk of included-but-failing transactions and gives validators confidence that transactions they include are adequately funded.
Storage, database, and networking optimizations
Raw execution speed is only one part of the puzzle. Monad also rethinks how state is stored and how blocks propagate in the network:
- Optimized storage engine - Monad uses a custom database tuned for EVM state access. This reduces memory pressure on nodes and speeds up state reads and writes, which is critical when many transactions are being executed in parallel.
- Efficient block propagation - Monad employs a targeted propagation protocol that reduces redundant network chatter and gets blocks and transactions to validators faster. That lowers latency and makes the whole system more efficient.
Taken together, these innovations reduce per-transaction cost because the network can carry more transactions for the same overall infrastructure cost - passing savings to users.
Practical implications for apps and developers
Monad’s higher throughput and lower fees are especially attractive for applications that need many small transactions: high-frequency DeFi strategies, complex multi-step smart contracts, active games, or micro-payments. Because Monad is EVM-compatible, developers can port Solidity contracts with minimal changes and then focus on testing performance and gas behavior under Monad’s asynchronous model.
But there’s a caveat: asynchronous and parallel execution introduces new patterns that developers should test for. Gas accounting, timing assumptions, and execution ordering might affect contract behavior differently than on Ethereum. So, measure performance, run unit tests, and use the testnet to understand how contracts behave under Monad’s model before deploying to mainnet.
Comparisons at a glance
- Ethereum - secure and decentralized, but limited TPS and higher fees during congestion. Execution is sequential and tightly coupled with consensus.
- Solana and similar fast chains - designed for high TPS and low latency, but not natively EVM-compatible, which forces developers to use different languages and tools.
- Monad - aims to combine the best aspects: EVM compatibility plus parallel and asynchronous execution for much higher throughput and lower fees.
Testnet reality check
Early testnets have been the proving ground. Observed TPS on testnets ranged from the hundreds into the low thousands as validators and load testing increased. These numbers show design concepts working in practice, but mainnet stress under real usage and diverse applications will be the real test. Developers should use the testnet to validate assumptions, measure gas consumption, and tune contracts for optimal behavior.
Risks and trade-offs
Complexity brings risk. Parallelism and asynchronous execution are powerful but require careful design to preserve determinism, prevent denial-of-service vectors, and handle MEV (Maximal Extractable Value) dynamics responsibly. Fee mechanics and inclusion costs introduce new economic behavior that will need monitoring and possibly adjustments as the network grows. Good audits, thorough testing, and active monitoring will be essential.
Conclusion
Monad is not just another “fast chain.” It’s a reimagining of how an EVM-based chain can process transactions: consensus-first, execution-later, and parallel where possible. That approach targets sub-second finality, thousands to tens of thousands of TPS, and substantially lower fees - while keeping the Solidity ecosystem intact.
If Monad delivers on its goals, it could let dApps scale without rewriting their stack - offering developers the familiarity of Ethereum with the performance of modern, high-throughput systems. As with any new architecture, testnets and early mainnet data will prove whether the theory holds in real-world conditions. For developers and teams, the recommendation is simple: test on the network early, measure carefully, and adapt contracts to the new execution model.
Encapsulate and others in the validator community are actively testing and preparing for mainnet participation, so the ecosystem is ready to learn and adapt as Monad evolves. The result could be a practical, high-speed lane for the EVM - one that keeps developer interest high while making everyday transactions cheaper and faster.
