In 2026, the Ethereum Layer 2 ecosystem is attracting developers not just with 'faster transaction speeds,' but with unique execution environment architectures. Builders must now select completely different networks based on the high-performance computational needs of their services, compatibility with zero-knowledge proof systems, and adherence to institutional regulatory compliance.

The most prominent trend is the contrast between the execution architectures of Arbitrum Stylus and Scroll. Through Stylus, Arbitrum has successfully established a dual virtual machine structure that runs WASM code written in compiled languages like Rust or C++ alongside the EVM. It is the top choice for dApps that require complex mathematical operations or high-performance cryptography, as it dramatically reduces on-chain computational gas costs. On the other hand, starting with the Euclid upgrade, Scroll has transitioned to the OpenVM proof architecture, a general-purpose RISC-V virtual machine. This allows developers to leverage powerful zero-knowledge proof capabilities while maintaining existing Solidity bytecode, without the need to learn complex zkVM-specific languages.

Meanwhile, Dunamu’s GIWA chain, which has recently gained traction, offers a completely different solution. Utilizing a self-managing tier on the OP Stack, the GIWA chain provides a fast 1-second block time and comes equipped with 'Dojang,' an identity authentication layer with built-in Ethereum attestation services, and 'Bojagi,' a zero-knowledge-based financial privacy layer. It is optimized for infrastructure where strict regulation and compliance are essential, such as in cross-border remittances or enterprise-grade solutions.

Ultimately, the choice of L2 in 2026 has moved beyond simple fee comparisons. It is time for smart design: choose Arbitrum Stylus for complex on-chain computations, Scroll for gas compatibility and robust zero-knowledge security, and the GIWA chain if institutional financial integration and global compliance are your top priorities.
