View ChartUsers and developers may take use of Ethereum’s robust security guarantees using Optimism, an extension that makes the platform faster, cheaper, and more user-friendly. One such exchange is Coinbase, where users may purchase and sell the OP token, which serves as a governance token.
Created by Ethereum developers, for Ethereum developers, Optimism is a lightning-fast, rock-solid, and scalable L2 solution. Your Ethereum programs will scale seamlessly with Optimism’s EVM-equivalent design. With a focus on creating a long-term ecosystem supported by public goods funding, Optimism is leveraging Ethereum’s current scale to finance its future.
A lot of the functions of the Ethereum network can be accomplished using optimism, but at a cost that is approximately ten times lower. Optimism users can do anything Ethereum users can, including purchase, sell, collect, mint NFTs, and connect with DeFi (decentralized financial) apps.
For their operations, optimism-based networks employ what are known as “optimistic rollups.” To alleviate network congestion and drastically lower transaction fees, this system executes transactions off-chain in groups.
To more fairly distribute the transaction cost among all users involved, Optimism’s rollup technology consolidates numerous transactions from Ethereum’s Layer 1 into a single transaction. The OP Mainnet, Optimism’s Layer 2 network, processes the rollup, while Ethereum’s Layer 1 handles the processing of the transaction data.
The “optimistic” part of this method is that it skips computations and starts by assuming that all transactions on Layer 2 of Optimism are genuine. The system will execute fraud-proofing to confirm a transaction if it suspects it may be fraudulent.
In contrast to zero-knowledge rollups, which verify the validity of all transactions before pushing them onto the main Ethereum blockchain, optimistic rollups do not assume anything. Pessimistic rollups is another name for these. Optimistic rollups usually offer less expensive transactions because such proofs are costly.
Optimism isn’t just about blockchain technology; it’s about a community of businesses, organizations, and individuals collaborating to create a bright future for Ethereum by rewarding public benefits. The code for Optimism is open-sourced and licensed under the MIT umbrella, unlike some other rollups. The specification is built with Ethereum in mind from the beginning, so everything is compatible and functions as expected on Ethereum. This means that developers can jump right into inventing on Optimism without having to learn new languages or rewrite code. A group of developers, builders, and crypto aficionados who share similar beliefs can be found on Optimism, the most forked rollup.

TradeA detailed comparison of Optimism (OP), Arbitrum (ARB), and Starknet (STRK) across Rollup architecture, multi-chain scaling, and token utility:
| Feature | Optimism (OP) | Arbitrum (ARB) | Starknet (STRK) |
|---|---|---|---|
| Rollup Architecture | Optimistic Rollup (Single-round fraud proof) | Optimistic Rollup (Multi-round interactive fraud proof) | ZK-Rollup (STARK Zero-Knowledge Proofs) |
| Appchain Framework | OP Stack (Superchain network) | Arbitrum Orbit (L2/L3 chains) | Madara / Appchains (Cairo-based ZK chains) |
| Key Projects | Base, World Chain, Zora, Mode | Arbitrum One, Arbitrum Nova, ApeChain | dYdX v4 testnet, Ekubo, Nostra |
| Governance & Value | Bicameral DAO + OP Buybacks + RetroPGF | DAO Governance + Treasury Voting + Sequencer Revenue | DAO Governance + Staking + Gas Fees |
Summary: OP leads in multi-chain expansion with OP Stack, ARB dominates in DeFi TVL, and STRK offers extreme scalability powered by ZK technology.
