How Does Optimism Compare to Competitors?

vs Arbitrum

Both are optimistic rollups with 7 day finality; however, Arbitrum utilizes its own AVM (Arbitrum Virtual Machine), whereas Optimism is equivalent in functionality to the EVM. Arbitrum has a much higher throughput (4500tps) than Optimism (2000tps); additionally Arbitrum can utilize multi round fraud proofs. Optimism has emphasized being Ethereum compatible and also has stronger enterprise level capabilities through OP Stack Customization.

Use Arbitrum when high-throughput is needed, use Optimism when EVM equivalence (to Ethereum) and enterprise customization (via the OP Stack) are needed.

vs Polygon

Polygon is a sidechain utilizing its own Proof of Stake Consensus and can support up to 65000tps and can do so at very low cost, however, this comes at a trade off of security to achieve scalability. Optimism provides Ethereum grade security and has a 99.99% Uptime SLA. Additionally Polygon has a larger number of ecosystem options available to developers, including Plasma and ZK-Rollups.

Use Polygon when large-scale throughput and low-cost are necessary in less-secure applications; use Optimism when you need Ethereum-grade security and enterprise deployment.

vs zkSync / ZK-Rollups

ZK Rollups provide significantly smaller proof sizes and provide instant finality vs Optimism’s 7 day challenge window. However, Optimism has broader EVM compatibility, a more mature ecosystem and lower operational complexity. Additionally, ZK based solutions generally require a greater amount of computation.

Use Optimism for its well-established and tested infrastructure; use ZK-Rollups if instant finality is a requirement and you can accept that your smart contract will be EVM compatible but with some degree of compromise.

What are the strengths and limitations of Optimism?

Pros

  • EVM Compatible — Your smart contracts run on the same way as they do on Ethereum without changing one line of code.
  • Battle-tested Security — 39+ security audits have been performed on OP Stack components and it has been used by two major exchanges, Coinbase and Kraken.
  • Enterprise ready OP Stack — A fully customizable and modular framework that enables the launch of custom blockchains; currently powering over 50 chains.
  • Inheriting Ethereum grade security — Because it is built on top of Layer 2 instead of Layer 1, Optimism maintains Ethereum grade security guarantees.
  • Industry leading uptime — Optimism has an uptime service level agreement of 99.99%; also has block times averaging 200 milliseconds and average transaction cost is sub-cent.
  • Open-source and permissionless — Optimism is free to deploy, and is an open protocol which allows anyone to create their own chain(s) or ecosystem(s).
  • Established ecosystem — The largest L2 userbase processes 15% of all cryptocurrency transactions, with multiple billion-dollar total value locked (TVL).
  • Utility of OP token for governance — The OP token is what is used to make governance decisions and fund public goods through the Optimism Collective.

Cons

  • 7-day finality window — Optimism uses a long withdrawal time frame from L2 to L1 which creates a 7-day challenge window for security purposes, thus slower than instant-finality solutions.
  • Lower throughput than competing options — Can support up to 2,000 tps, compared to the 4,500 tps supported by Arbitrum and 65,000 tps supported by Polygon; therefore may limit scalability for extreme demand.
  • Not decentralized enough — Still under control of the Optimism Foundation; an ongoing process of decentralizing, resulting in governance uncertainty.
  • Requires custom bridge infrastructure — Cannot automatically bridge L2 specific tokens; complex to achieve cross-chain liquidity.
  • The price of L1 Gas depends on how much you pay for L1 Data Fees. Since L1 Data Fees are based on Ethereum Base Fees, your costs will be highly unpredictable at times when there is a lot of congestion.
  • Complexity in adopting OP Stack — To develop custom chains using OP Stack, developers need an abundance of experience in building large-scale infrastructure and maintaining it.
  • Learning Curve for Enterprise Users — In order for enterprise users to use OP Stack, they must have knowledge of Rollup Mechanics, Fraud Proofs, and Development Patterns that are specific to Layer 2 systems.
  • Risk of Vendor Lock-In — Because OP Stack relies heavily on the Technical Roadmap and Governance Decisions of the Optimism Foundation, if you adopt OP Stack as your Layer 2 Solution, you will have a very high level of dependency on the Optimism Foundation.

Who Is Optimism Best For?

Best For

  • DeFi platforms and financial services — Enterprise-Ready Infrastructure With 99.99% Uptime, EVM Equivalence for Seamless Smart Contract Migration, and Strong Governance Models to meet Decentralized Governance Needs
  • Enterprise blockchain deployments — Custom Chain Launches enabled through OP Stack with over 50 Powered Chains that currently operate with $16 Billion in Total Assets — Each of these custom chains has configurable controls and Compliance Features.
  • Teams requiring Ethereum security guarantees — Has the same grade of Security as Ethereum which is far superior than other alternatives for L2 Solutions, and has been audited 39+ times, and is used by Major Platforms such as Coinbase
  • EVM-native projects seeking lower costs — Is a Drop-In Replacement for Ethereum with a Transaction Cost Reduction of 200x ($0.001 average fees compared to Ethereum’s $1-$5), and does not require any modifications to your existing Smart Contracts
  • Blockchain infrastructure providers — Is an Open-Source Modular Framework for the OP Stack — This allows developers to build their own customized Scaling Solutions without having to worry about Licensing Fees or Vendor Lock-In.
  • Large-scale consumer applications — Can Handle Hundreds of Millions of Users Across its Ecosystem — OP Stack has a Proven Track Record and Mature Developer Tooling.

Not Suitable For

  • Applications requiring instant finality — 7-Day Challenge Window — Prevents Real-Time Withdrawals. If you Need Instant Finality Consider Using zkSync or Other ZK-Rollups.
  • Ultra-high-throughput applications (>10k tps) — 2,000 TPS Max on OP Mainnet — If you Need Massive Scale Consider Polygon (65k TPS) or Solana.
  • Cost-sensitive projects with tiny margins — L1 Data Fees Fluctuate Based on Ethereum Congestion — These Costs Will Spike at Times When There is a Lot of Congestion. Consider Polygon For Lowest Guaranteed Costs.
  • Teams without Ethereum/Web3 experience — Developers Must Understand How Layer 2 Systems Work, Smart Contracts, and Blockchain Concepts — Therefore, this is Not Suitable for Traditional Development Teams.
  • Privacy-critical applications — All Transactions Are Recorded On Public Blockchain — Consider Private/Confidential Computing Solutions If You Have Privacy First Requirements.
