How Does StarkNet Compare to Competitors?

vs zkSync Era

StarkNet utilizes STARK proofs (quantum-resistant, no trusted setup); while zkSync utilizes SNARKs (smaller proofs however requires trusted setup); StarkNet has Cairo native smart contract support to provide faster scalability compared to zkSync’s EVM compatibility.

StarkNet if you want maximum scalability and future-proof cryptography; zkSync if you are an EVM developer.

vs Polygon zkEVM

While Polygon has a larger ecosystem it focuses on providing EVM equivalence to make Ethereum migration easier while StarkNet prioritizes performance using a custom Cairo Virtual Machine; StarkNet provides higher theoretical throughput.

If you have an EVM dApp then Polygon would be best, otherwise StarkNet will be best for high-performance optimized applications.

vs Optimism (OP Stack)

Optimistic rollup with lower cost and/or faster short term costs, but longer withdrawal periods (7 days); StarkNet has faster withdrawal periods and more robust cryptographic security, however there is a significant learning curve associated with Cairo when compared to the EVM used by Optimism.

If you want fast speed with EVM right now then Optimism would be best; otherwise, StarkNet for security and Ethereum compliance.

vs Arbitrum

Arbitrum is the leader in optimistic rollups for having massive TVL and EVM; StarkNet is behind in terms of adoption, but it has strong proof based security and potential to be used at L1 levels. Both are targeting Ethereum scaleability.

Arbitrum for current adoption; StarkNet for first validity.

What Are Common Questions About StarkNet?

StarkNet is a Layer 2 scaling solution built atop Ethereum that utilizes STARK (Scalable Transparent Argument of Knowledge) cryptographic proofs to increase the number of transactions processed while lowering costs while maintaining both security and decentralization. It is able to process thousands of transactions per second via zero-knowledge rollups.

A StarkNet bundle contains a series of transactions within a single proof that is verified on Ethereum mainnet; this increases the transaction capacity. It processes computations off of chain while verifying the proofs on-chain; this reduces the amount of data being processed and the gas fees associated with processing that data while still utilizing the security offered by Ethereum.

Cairo is a Turing complete language designed for developing provably correct programs. Cairo was chosen as the programming language for StarkNet because of its ability to support high-complexity computations at low overhead. Programs written in Cairo are compiled into a form which can be run directly by the STARK system for fast verification.

Yes, StarkNet achieves the same level of security as the Ethereum mainnet through use of the Ethereum mainnet for proof verification. STARK proofs have been shown to be mathematically sound, to be completely transparent and to not require a trusted setup. Additionally, the cryptographic system used is resistant to both quantum attacks and other forms of attack.

StarkNet has many potential applications, such as DeFi lending and borrowing systems with much faster transaction times than on Ethereum, gaming platforms where players can make cheap in-game transactions, NFT systems where users can mint new NFTs at lower cost than they would be able to on Ethereum, and any other type of dApp that requires high-throughput and low-fee transactions.

By batching transactions together and then submitting a single STARK proof to the mainnet, StarkNet can greatly reduce the amount of money paid in gas fees relative to the amount paid on the Ethereum mainnet. The degree of reduction will depend upon the number of users and the volume of activity on the StarkNet network, but the design of the architecture should help minimize on-chain data processing and storage requirements.

A zk-rollup (zero-knowledge rollup), as the name suggests, aggregates many off-chain transactions into one on-chain transaction. This is what StarkNet does to allow for a large-scale computation architecture while allowing for composability with Ethereum.

Yes, StarkNet is based on an account-based model, and utilizes the same security model as the Ethereum mainnet. Users interact with the network via account contracts, providing them access to account abstraction and other advanced security features.

Is StarkNet Worth It?

StarkNet is an example of a technically sophisticated layer two solution using STARK cryptography to help solve ethereum’s scalability problems. StarkNet has a solid technical foundation in combination with proven proof systems (over 400 million transactions have been successfully settled) and a developer friendly Cairo language making it a suitable choice for production deployments. However, StarkNet is also a highly specialized solution that requires developers to be familiar with the Cairo language and to understand its underlying technology.

Recommended For

  • DeFi protocol builders requiring high volume throughput at low transaction cost
  • Gaming Studios & NFT platforms that require scalable architecture
  • Organisations that are prioritising the use of mathematical security and quantum resistant cryptography.
  • Native Ethereum Projects that are looking to deploy permissionless Layer 2 solutions without compromising on their security.

!
Use With Caution

  • Teams that do not know Cairo language – will require to learn a new programming paradigm.
  • Projects that are requiring production ready as quickly as possible, without a thorough technical risk assessment.
  • Organisations that require a large-scale customer support infrastructure – community based support model may not be sufficient.

Not Recommended For

  • Teams that prefer ease of development to scalability – will require Cairo language knowledge.
  • Applications that require immediate mass adoption by users – Ecosystem is still developing.
  • Organisations that require traditional Enterprise Vendor Support Guarantees.
Expert's Conclusion

StarkNet is best suited for teams with significant technical sophistication that can build scalable ethereum applications using mathematical security, developer autonomy, and future-proof cryptography with less focus on ease of adoption.
