Pros & Cons
Key Benefits
EVM+ ensures existing EVM contracts, dApps, and tools work seamlessly on Arbitrum Nitro, easing the transition for Ethereum developers.
Enhanced Performance
Dual VMs offer improved efficiency, parallelism, and throughput, enhancing smart contract execution.
Flexibility
Developers gain versatility in application development, choosing between the traditional EVM and the additional VM.
Security
Arbitrum Nitro's security is expected to match or surpass previous versions, maintaining rigorous standards.
Interoperability
The integration of Solidity and WASM programs removes language barriers, promoting diverse development.
Innovative Use Cases
Stylus overcomes constraints, opening possibilities for on-chain gaming and generative art.
Red Flags
Integration Issues
Despite EVM+ being additive, some existing tools or apps might face integration challenges.
Adoption Uncertainty
The adoption rate of this new paradigm within the Ethereum and dApp community is not guaranteed.
Security Complexities
Managing two VMs introduces potential security risks, especially in their interaction.
Increased Complexity
The introduction of a second VM adds complexity, potentially steepening the learning curve for developers and users.
Initial Language Support
Early support is stronger for Rust, which could limit initial development diversity.
Dependency on Fraud-Proving Tech
Stylus' security heavily leans on Arbitrum Nitro's fraud-proving technology, making it critical for overall safety.
New Tech Risks
As a new technology, unforeseen bugs or vulnerabilities could arise, presenting risks to users and developers.
