🧵 SOON vs Arbitrum vs OP Stack: Modular L2 Architectures Compared Rollups are evolving. While Arbitrum and OP Stack scale the EVM, SOON Network takes a radical approach — importing the Solana VM into Ethereum’s modular world. Here’s a deep technical comparison of 3 L2 design philosophies 👇

2/ VM Execution Layer 🔹 Arbitrum: Uses ArbOS on WASM, re-executes EVM bytecode Custom WASM runtime, supports Nitro optimizations Stays within EVM constraints 🔹 OP Stack: Canonical EVM rollup Minimal deviation from Ethereum semantics Easier L1–L2 porting, but limited in performance 🔹 SOON: Decoupled Solana VM (SVM) Executes Rust smart contracts (via Sealevel) Native parallelism, not bound to EVM gas model ✅ Verdict: SOON introduces runtime modularity, allowing cross-VM execution (EVM ↔ SVM)

3/ Parallelism OP Stack & Arbitrum: sequential execution (same as Ethereum) SOON: Sealevel parallelism → concurrent contract execution via static account analysis This enables: Better CPU utilization More efficient tx throughput for compute-heavy dApps Deterministic conflict detection

4/ Data Availability (DA) Arbitrum: posts data to Ethereum; some chains use AnyTrust committee for partial DA OP Stack: Ethereum blob (EIP-4844) by default; modular EigenDA support SOON: full modular DA: Ethereum calldata/blobs, Celestia, EigenDA, Avail SOON treats DA as swappable

5/ Interoperability & Messaging Arbitrum: AnyTrust bridge + native tooling OP Stack: Standard bridge infra, working on shared sequencer mesh SOON: InterSOON built on Hyperlane → supports trustless messaging across EVM, SVM, Cosmos SOON enables cross-VM message passing, not just token bridging.
