- [In today's article, I gave you information about the unified execution layer of the Fluent project. Enjoy reading.

Recently, blockchain applications running on different virtual machines (VMs) have been rapidly multiplying. Each VM has its own unique advantages: the EVM offers excellent tooling support, the SVM delivers powerful parallel execution, and the Move language brings formal verification capabilities. However, under the current architecture, an application is tied to a single VM. This creates serious limitations for both developers and users. For instance, enhancing a Solidity app with a Rust library, or allowing a Solana developer to reach EVM users, often requires bridges, wallet changes, and comes with various security risks.

This is exactly the problem Fluent aims to solve. Fluent is an Ethereum L2 network that enables blended execution—bringing together different VMs in a unified runtime environment. This means applications written in Rust, Solidity, or even TypeScript can now run together natively and concurrently, without the need for bridges or extra work on the user side.

At the core of this system are "compatibility contracts" representing each VM, and an architecture that compiles all of them down to a shared execution layer called rWasm. Optimized for zero-knowledge proofs, this design makes concurrent execution across VMs both secure and efficient.

In my view, this approach represents a new paradigm in blockchain: freedom in application development, unity in user experience. Fluent’s unified execution model paves the way for multi-VM compatibility to become the new standard in the future. As I mentioned, Fluent is a truly promising project—I believe the amount of investment it attracts will only increase.

- [A Revolution in the Execution Layer: My Thoughts on the Open Execution Network

After reviewing Altius’s “Open Execution Network” vision, I realized they are addressing a truly critical gap in blockchain architecture.

Until now, transaction execution has generally been embedded in the chain itself — centralized or tightly coupled with the chain’s structure. But Altius aims to transform this into an open, decentralized execution network with parallel processing capabilities.

Initially, they introduced a model called “shared execution,” offering high-performance execution services for L1 and L2 chains. This means chains can improve their performance without overburdening their own infrastructure — essentially enabling “execution as a service,” which brings both cost savings and more efficient transaction handling.

But the most important innovation lies in the Open Execution Network (OEN) model.
In this system, it’s not just Altius running the execution layer — anyone can become an executor.
If you have sufficient computational resources and stake the required tokens, you can join the network and execute transactions for different chains. The dual staking model (requiring both Altius and target chain tokens) is a particularly smart design — it strikes a real balance between incentives and security.

What I like most about this model:

Permissionless: No central authority is needed to join. That’s a huge threshold to cross.

Truly decentralized: It eliminates single points of failure.

Efficient: Lower costs and more flexibility for developers.

Interoperable: Cross-chain transactions become much easier to integrate.

Especially in scenarios involving a multi-chain future, I believe this structure could become a foundational infrastructure layer.

Altius’s vision isn’t just about performance gains in the execution layer — it’s about demonstrating how execution can be shared and distributed more fairly.

To me, this isn’t just a technical improvement — it directly serves the core values of Web3: openness, participation, and security.](https://paragraph.com/@logart/a-revolution-in-the-execution-layer-my-thoughts-on-the-open-execution-network-after-reviewing-altius-s-open-execution-network-vision-i-realized-they-are-addressing-a-truly-critical-gap-in-blockchain-architecture-until-now-transaction-execution-has-generall)
- [Rust + Solidity in the Same Application? Fluent Makes It Happen

I recently took a look at Fluent’s public devnet, and to be honest, this idea of “blended execution” really got me excited.

The fact that smart contracts written in different languages like Rust, Solidity, and Vyper can directly call each other within the same application is, in my opinion, a major breakthrough for on-chain development.

They’ve demonstrated this for the first time with a real example: a chess engine written in Rust validates a move, and then directly calls a reward contract written in Solidity. In other words, the traditional “either EVM or Wasm” constraint is now gone. You can use the best of both worlds at the same time.

This is especially crucial for applications that require high performance but also need EVM integration. Just like in Web2, where you choose the best language for each task, Fluent seems to be bringing that flexibility to Web3.

Another plus is that Fluent’s devnet is currently live, fully accessible, and open to developer feedback. It’s still in the early stages, but I think it’s definitely worth experimenting with and thinking about.

I already have a few ideas forming in my head. If this infrastructure matures, we’ll see much richer and more powerful applications in Web3.

Truly exciting times ahead.
