As the blockchain ecosystem grows, the separation among different virtual machines is increasingly becoming a bottleneck for development and composability. Developers often need to migrate logic across chains or execution environments, adding to system complexity and security risks.
This challenge involves three main aspects: unified execution models, cross-VM interaction, and state management—all foundational to Fluent’s design.
What Is Fluent (BLEND)
Fluent is a Layer2 system built around multi-virtual machine blended execution, designed to eliminate the boundaries between different execution environments.
Fluent enables EVM, SVM, and Wasm contracts to operate on the same network, allowing direct interaction through a unified execution layer. Developers can implement complex logic without relying on bridges or cross-chain communications.
Structurally, Fluent leverages a zkRollup framework, running execution on Layer2 while using Ethereum as the settlement layer for security.
This approach enables multiple development paradigms to seamlessly coexist, boosting overall development efficiency.
How Blended Execution Works in Fluent
Blended Execution is Fluent’s core execution mechanism.
Code from different virtual machines is converted into a unified execution format, allowing it to run in the same execution environment. The process maintains atomicity, so cross-VM calls can be completed within a single transaction.
This model relies on an execution abstraction layer and a compilation layer, unifying multiple languages and VMs into a single execution system. State is shared across VMs, preventing data silos.
This makes cross-environment interaction a built-in system capability, dramatically increasing composability.
Fluent’s Multi-VM Architecture
Fluent’s foundation is its multi-VM architecture.
The system supports EVM, SVM, and Wasm execution environments, unifying their interfaces through an adaptation layer so they can work together in a single execution flow.
Fluent comprises an execution abstraction layer, a VM adaptation layer, and a state synchronization layer. These components ensure consistent execution results across all VMs.

This architecture lets developers choose the optimal execution environment on a single network, without migrating to other chains.
How Fluent’s Execution Layer and zkRollup Mechanism Operate
The execution layer and rollup mechanism are critical to the network’s performance and security.
Transactions are computed on Layer2, producing state updates that are then verified on Ethereum’s mainnet using zero-knowledge proofs.
zkRollup compresses the computation, uploading only proof data to the mainnet—reducing data load and increasing efficiency.
This design delivers higher throughput and lower costs without compromising security.
The Role of rWasm in Fluent’s Execution System
rWasm is a crucial component of Fluent’s execution system.
It provides a unified execution environment, allowing code from different VMs to be processed and generate verifiable results. rWasm also supports zero-knowledge proof generation.
At the heart of the execution layer, rWasm bridges the compilation and verification layers, enabling multi-VM execution within a single framework.
This ensures that multi-VM execution is both feasible and verifiable, underpinning system security.
The Role of BLEND Tokens in the Fluent Network
The BLEND token serves as the economic backbone of the network.
BLEND is used for transaction fees, governance, and incentivizing network participants. Every computation and interaction may involve token movement.
The token links user actions to system resource allocation, creating a closed loop between the execution and economic layers.
This design means network operation depends on both technical architecture and economic incentives for stability.
Fluent’s Application Scenarios and Developer Ecosystem
Fluent’s application scenarios demonstrate the system’s real-world value.
Fluent supports cross-VM DeFi, complex smart contract composability, and multi-language development—all enabled by its unified execution environment.
Developers can deploy various contract types on the same network and invoke them directly, building sophisticated systems.
This ecosystem structure enhances flexibility and reduces the cost of cross-environment development.
How Fluent Differs from Traditional Layer2 or Multi-Chain Solutions
Fluent stands apart from traditional solutions in both execution model and interaction design.
Traditional Layer2 solutions usually center on a single VM (such as EVM on Ethereum-compatible chains), while multi-chain approaches connect networks via bridges. Fluent, in contrast, fuses multiple VMs through a unified execution layer, making cross-environment interaction a core system feature.
The fundamental difference lies in execution environment architecture. Some paths continually optimize single-VM performance (as with Monad’s approach), others expand through network scaling; Fluent abstracts and integrates at the execution layer, enabling different VMs to share a unified state space.

Mainstream scaling strategies fall into three categories:
- Multi-environment collaboration through execution-layer fusion (Fluent)
- Maximum performance optimization in a single VM (e.g., Monad)
- Horizontal scaling via multi-chain architectures
These differences make Fluent ideal for complex cross-VM applications, while single-VM high-performance solutions are better for use cases with uniform execution logic.
Fluent’s Advantages and Limitations
Both advantages and limitations define Fluent’s technical boundaries.
Fluent’s strengths are in multi-VM blended execution and high composability; its constraints come from increased system complexity and implementation challenges.
Its unified execution environment and scalability are major advantages, while a higher development barrier and an evolving ecosystem are current limitations.
This balance indicates Fluent is best suited for complex applications, while simple projects may not require a multi-VM architecture.
Summary
By integrating multiple execution environments with Blended Execution and a multi-VM architecture, Fluent unifies composability and defines a new Layer2 paradigm.
