Hyperion utilizes parallel processing for onchain transactions. No more bottlenecks, no more gas wars. Just fast, conflict-free execution. Chains like Sei Network and Monad are pioneering parallel execution. Hyperion, built using Metis technology, joins this frontier as a high-throughput Layer 2 designed specifically for intelligent, scalable applications. This article explains how it works.
Most blockchains today still process transactions one at a time. This ensures correctness but limits throughput and responsiveness, especially during periods of high activity. Many AI agents and dApps try to minimize onchain activity, but when quick onchain reads and writes are needed, such as in games, real-time decisions or social apps, slow transactions cause real problems.
Hyperion introduces parallel execution, allowing many transactions to run simultaneously. It assumes no conflicts will occur and resolves only those that do. This dramatically increases transaction capacity while maintaining correctness.
Hyperion uses optimistic execution to speed up processing. Each transaction runs in parallel, assuming that it won’t conflict with others. This process follows 3 general steps:
1. Multiple transactions execute at the same time using available CPU cores.
2. A multi-version memory system (MVMemory) tracks all versions of the state data as transactions are executed.
3. Each transaction log is a read and write set, detailing exactly what parts of the state it interacted with.
This approach enables high throughput without compromising safety.
Once all transactions have executed optimistically, the system checks for conflicts. It looks at each transaction’s read set to see if any earlier transaction modified that data.
If a conflict is found, meaning a transaction reads stale data, it is re-executed with the updated state. This ensures that all dependencies are resolved correctly.
The process repeats until all transactions are complete without conflict. The end result is a block of transactions that could have been processed sequentially but were instead executed in a fraction of the time.
Three main systems coordinate Hyperion’s parallel execution:
Scheduler assigns transactions to worker threads and manages re-execution when needed.
MVMemory maintains all state versions, helping isolate transactional effects and resolve the data each transaction should read.
VmDB connects the EVM to MVMemory, intercepting reads and writes while tracking dependencies.
These components ensure high-speed execution while preserving determinism and network safety.
Hyperion improves efficiency through a set of low-level execution enhancements. It uses deferred updates for common operations like gas payments and ETH transfers, reducing unnecessary dependencies. Lock-free data structures keep CPU threads running smoothly without blocking, while pre-execution dependency graphs help predict conflicts before they occur. Transactions are also scheduled strategically to minimize overlap and re-execution. These combined optimizations increase throughput without adding complexity to the system.
Even with transactions executing in parallel, Hyperion ensures a deterministic final state. The output of any block is guaranteed to match what would result from sequential execution, by respecting the original transaction order during conflict resolution.
This makes Hyperion compatible with Ethereum’s requirements and ensures consistency across all network participants.
Hyperion is part of a broader trend in high-performance blockchain design but stands apart in its focus on AI scalability. Onchain AI agents benefit from low-latency environments, concurrent interactions, and high-throughput pipelines.
For example, an AI trading agent on a DEX would need to read onchain prices, slippage and gas fees in real time. If this is processed too slowly the trade could fail or miss best price execution. Hyperion provides the infrastructure to support high throughput demands, making it a launchpad for real-time, intelligent applications that can scale.
Where Metis Andromeda focuses on production-grade deployments, Hyperion explores the outer limits of scalability and tests innovations like parallel transaction execution that are critical to supporting decentralized AI.The Hyperion Testnet is live and open to all developers. Teams are already launching agent marketplaces, AI-driven dApps, and real-time coordination tools using its infrastructure. Hyperion is more than just an L2. It is the infrastructure layer for scalable, AI-native blockchain ecosystems.
