More on Optimism: Ethereum’s L2 Infrastructure Network

What is optimism? Why is it important?

Every time someone trades on Coinbase’s Base, swaps on Uniswap’s proprietary chain, or opens a perpetual trade on Kraken’s Ink platform, they are unknowingly using Optimism’s infrastructure. The project has evolved from a single Ethereum scaling solution to an invisible backbone powering 15% of all cryptocurrency transactions.

The numbers speak for themselves. The total amount locked is $17 billion, over 50 interconnected blockchains, up to 24 million daily transactions at approximately $0.001 each, and 200ms block time with 99.99% uptime. When the largest cryptocurrency exchange needed reliable Layer 2 infrastructure, it built on Optimism’s open source framework for launching compatible chains, OP Stack.

This is more than just a scaling solution competing for market share. The superchain model represents a fundamental shift in how blockchain networks can collaborate rather than compete. Instead of isolated chains fighting for liquidity, the ecosystem allows specialized chains to serve different use cases while sharing security through Ethereum. base Serving mainstream retail users, Unichain is optimized for DEX trading and Ink powers derivatives are all interconnected and all run the same underlying technology.

The $6.2 billion of stablecoins locked across the network represents real usage rather than speculative positioning. Institutions and retail users alike route real economic activity through this infrastructure, making Optimism one of the few crypto projects whose adoption metrics match marketing claims.

How did optimism evolve from concept to infrastructure?

The journey from white paper concept to infrastructure standard required five years of technical iterations, a strategic pivot, and one key insight. That is, building a single chain will never solve Ethereum’s scaling problems.

Fundamentals and early development (2019-2021)

ben jones, Karl Frosh, Jingran Wangand Kevin Ho We founded Optimism PBC in 2019 around specific technology bets. Rather than pursue a zero-knowledge proof that would require complex cryptography but immediately yield finality, they opted for an optimistic rollup. This approach assumes that a transaction is valid unless someone proves otherwise during a 7-day challenge window. This design prioritized value over speed: full compatibility with existing Ethereum tools.

When mainnet launched in 2021, developers were able to deploy Solidity contracts without any changes. Same code, same tools, same debugging workflow. DeFi protocols seeking lower gas fees emerged first, but trading volumes remained modest. The team recognized a fundamental limitation. That means no single chain, no matter how efficient, cannot absorb Ethereum overflows.

Super chain pivot (2022-2023)

The 2022 token airdrop was more than a governance milestone, it funded a retrospective public goods experiment that defined the project’s identity. But the real strategic shift happened in 2023, when the team open sourced its OP stack and invited competitors as collaborators.

That bet was validated as Coinbase launched Base as its first major superchain implementation. With over 100 million authenticated users, the company chose to adopt shared technology instead of building its own infrastructure. Modular architecture allows you to customize it to your needs while maintaining interoperability with the broader network. Other chains followed suit, including Uniswap’s Unichain, Kraken’s Ink, and Sony’s Soneium.

Acceleration phase (2024-2025)

Governance matured into a dual-house system for Optimism Collective by 2024, with RetroPGF distributing millions of dollars to ecosystem contributors. As institutional investor confidence grew, TVL surpassed $10 billion.

This pace accelerated further into 2025. Flashblocks reduced pre-check time to 250ms in September. Enterprise Yield Stack was launched in October through a partnership with Morpho and Gauntlet and targets institutional DeFi. Bitcoin This integration was made possible in December through Build on Bitcoin and LayerZero’s kBTC introduction.

By December 2025, Kraken’s Nado perpetuals platform had reached $1 billion in trading volume within 10 days of launch. Ben Jones is Forbes 30 under 30 His work scaling Ethereum infrastructure is listed in the Finance category. Each milestone strengthens the infrastructure of the last.

What is the difference between Optimistic Rollup and other scaling solutions?

While the technical distinction sounds abstract and assumes validity rather than proof, the practical implications shape everything from developer experience to exit time.

trust model

Zero-knowledge rollup generates a cryptographic proof for each batch of transactions, which requires a large amount of computational resources but provides finality quickly after verification. Optimistic rollups flip this. Transactions are valid by default, and proof of fraud is only required if someone disputes the state transition during the 7-day challenge window.

The premise of security is simple. As long as one honest validator monitors the chain and submits fraud proofs for invalid state changes, the system remains secure. Anyone can run a validator, and the cost of proving fraud is less than the value of preventing theft. Mathematically, honesty is an advantage.

Developer experience as a competitive advantage

full E.V.M. Equivalent means that existing Ethereum contracts are deployed without modification. There are no new languages, adapted tools, or rewritten tests. Hardhat, Foundry, and Remix work similarly. Debugging follows a familiar pattern. The friction of the transition is reduced to almost zero.

This compatibility turned out to be more valuable than raw performance metrics. Developers can ship faster without retraining. Auditors use established methodologies to verify the code. The entire Ethereum tool ecosystem will be transferred directly.

cost structure

Batch processing spreads for transactions layer 1 The cost of calldata is incurred over hundreds of transactions. The sequencer collects, orders, and posts compressed batches to Ethereum. Users pay a proportionate L1 gas cost and a small L2 execution fee (typically $0.001 for a transfer or swap). Microtransactions become economically viable if mainnet fees exceed the transaction amount itself.

This trade-off surfaces during withdrawal. You will need to wait the entire challenge period to transfer your assets back to Ethereum. Third-party bridges provide a faster alternative by ensuring liquidity, but introduce additional trust assumptions. We believe this is acceptable for users who prioritize capital efficiency over instant access. People who frequently make L1 moves often prefer zero-knowledge alternatives.

How does the OP stack enable horizontal scaling?

Speeding up a single chain by vertical scaling will eventually reach a physical limit. Horizontal scaling (adding chains) distributes the load without degrading existing performance. The OP stack makes horizontal scaling practical by standardizing the way new chains launch and communicate.

modular architecture

The stack separates blockchain functionality into interchangeable layers. Data availability determines where transaction data is stored (Ethereum, Celestia, or a custom solution). Sequence control blocks production and orders. Execution processes transactions through EVM or an alternate virtual machine. The settlement will finalize the state’s route on Ethereum.

Developers modify individual layers without forking the entire codebase. Gaming chains may prioritize throughput over instant payments. DeFi chains are likely to emphasize security and quick withdrawals. Both share Ethereum’s set of validators for security while optimizing them for specific requirements.

Customization without fragmentation

The project avoids maintaining a separate security infrastructure while gaining flexibility in chain-specific optimizations. The shared security model means that new chains do not need to bootstrap an independent set of validators. They inherit Ethereum’s time-tested consensus.

Cross-chain coordination is done through standardized messaging protocols. Chains operate independently until interaction requires coordination. Once coordination is required, an interoperability layer (coming to testnet in early 2026) facilitates atomic transactions and message passing.

Future improvements

PeerDAS integration distributes data availability sampling across the validator set, allowing nodes to validate availability without downloading the entire blob. Custom gas token support allows chains to specify fees stable coin Or use native assets to eliminate ETH price fluctuations from your operational plan. Plasma implementations provide higher throughput for certain data types, with different security tradeoffs.

What is a superchain and how does it work?

Superchain connects independent OP Stack blockchains into a unified network. Assets and applications move between chains with minimal friction, and each chain maintains its own block generation and state execution.

network architecture

Think hub and spoke. Ethereum Each chain serves a specific type of traffic while serving as a source of truth and authority. Security flows from Ethereum payments and standardized anti-fraud mechanisms. High-value DeFi applications choose chains with conservative configurations. Consumer applications are deployed where throughput is more important.

An interoperability layer currently in development will enable atomic transactions across multiple chains. Users can exchange tokens on Base, provide liquidity on OP mainnet, and stake rewards on Unichain in a single transaction bundle. If a step fails, it triggers an automatic rollback across all chains involved.

Chain specialization

Different chains have different purposes.

base (approximately $4 billion TVL): Coinbase’s gateway for mainstream users. DeFi protocols, NFT marketplaces, and social applications benefit from seamless exchange integration.

unichain ($280 million in DEX volume per day): Uniswap’s vertical integration strategy. Fast block times and low latency execution optimize trading performance.

ink (880,000 transactions daily): Kraken’s derivatives and trading ecosystem. Nado Perpetual reached $1 billion in sales within 10 days of its launch.

Soniam, World Chain, Cero: consumer applications, identity-verified transactions, and mobile-first payments, each serving a community with specific requirements.

Standardize performance

A consistent 200ms block time across the chain means developers can write an application once and deploy it anywhere without having to adjust different timing assumptions. Users experience similar performance regardless of which network they are communicating with. This standardization reduces the learning curve when moving between environments. This is important for mainstream adoption.

Who is adopting Optimism and what applications are running on the network?

Deployment patterns reveal how different user segments choose infrastructure based on integration points, performance characteristics, and existing platform relationships.

Exchange-based entry points

Base leverages Coinbase’s existing user base for mainstream onboarding. Users move between centralized and decentralized environments with minimal friction: deposit fiat to Coinbase, bridge to Base, interact with DeFi, bridge back, and withdraw. A seamless loop lowers the barriers that traditionally kept retail users on centralized platforms.

Ink serves users focused on Kraken trading. Spot trading, perpetual trading, and staking operations are performed on dedicated infrastructure optimized for the exchange’s use cases. Gelato provides automation and gas abstraction to reduce operational complexity for both developers and users.

Protocol-specific infrastructure

Unichain demonstrates the value of vertical integration. Rather than relying on general-purpose chains, uniswap Control the entire trading stack including block generation, ordering, and execution. Liquidity providers earn fees in a high-throughput environment, but the final settlement is still locked to the security of Ethereum.

This pattern, a protocol launching a dedicated chain, suggests where the ecosystem is headed. Applications with sufficient volume justify the operational overhead of running specialized infrastructure.

Adoption of DeFi protocols

Major protocols are spread throughout the ecosystem. Synthetix provides synthetic assets and permanent files across multiple deployments. Aave, Compound, and lending protocols serve institutional investors and individual borrowers. NFT marketplaces allow creators to choose environments based on audience demographics and gas costs.

Recent partnerships go beyond basic DeFi. THORSwap’s November integration enables cross-chain swaps between Superchain assets and external ecosystems like Bitcoin and Cosmos. Gauntlet introduced an institutional-level risk assessment tool in December. The infrastructure layer continues to scale without requiring changes to the core protocols.

How does governance work in the Optimism Ecosystem?

Separating economic power from technical decision-making prevents pure financial gain from overriding long-term ecosystem health. Rather than relying on good intentions, Optimism Collective’s dual-house system attempts to achieve this balance through structural design.

dual house structure

Token holders form one chamber and vote on financial allocation, fee structure, and RetroPGF rounds. The Citizens House is made up of individuals who have made meaningful contributions to the ecosystem and can consider changes to protocols and veto proposals that conflict with the community’s values.

In Season 8 (June 2025), participants expanded beyond token holders to include application developers, infrastructure providers, and enthusiastic users. This update adds a veto that prevents purely economic votes from overriding technical or ethical concerns.

How tokens work

of $OP The token serves governance and operational functions. Holders vote through a weighting mechanism tied to their token balance and delegation pattern. This token also pays for prioritization on some chains and provides discounts on protocol fees. The burning mechanism removes tokens based on network usage, creating deflationary pressures related to actual activity.

Retroactive public goods funding

RetroPGF reverses the traditional subsidy model. Instead of committing to funding, reward demonstrated value. Round 3 was rolled out in early 2025 with subsequent monthly distributions. General ecosystem support generated 2 million OPs, and February saw 8 million OPs dedicated to developer tools.

The funding goal is up to $250 million in monthly cross-chain subsidies by the end of 2025, up from the original goal of $100 million. Fees generated from over 22 million transactions each day generate the revenue base. The Collective reviews spending effectiveness quarterly and adjusts allocation strategies based on measured impact.

proposal process

Submission requires minimum token possession or Citizen House approval. Voting will take place over two weeks for standards and four weeks for constitutional amendments. The quorum is expanded depending on the impact of the proposal. Controversial changes require broad agreement.

What challenges does optimism face?

Technological achievements and ecosystem growth do not eliminate structural constraints and competitive pressures. Understanding the challenges will give you clarity on what needs to be addressed in your roadmap.

drawer problem

The seven-day withdrawal period creates real friction. Users experience this as locked capital that cannot be deployed elsewhere. Third-party bridges provide a faster alternative, but introduce trust assumptions that the base protocol avoids.

Zero-knowledge competitors such as zkSync and StarkNet offer sub-hour withdrawals through proof of validity. This is important for users who frequently move between L1 and L2. Optimism values ​​EVM parity over instant finality, trading withdrawal speed for developer experience. This is a calculated choice that disadvantages certain use cases.

competitive dynamics

Arbitrum maintains a higher TVL on its primary chain (over $3 billion vs. ~$565 million for OP Mainnet). While the $17 billion total for all Superchain chains shows the effectiveness of a multi-chain strategy, this comparison highlights that no single optimistic chain will dominate on its own.

Cosmos IBC pioneered interoperable sovereign chains before Ethereum L2 adopted a similar model. Cosmos Chain uses IBC for communication while maintaining independent validators and governance. Superchains trade sovereignty for shared security and direct access to Ethereum liquidity. Different projects have different trade-offs that are attractive.

Concerns about centralization

The Optimism Foundation will manage a significant OP Reserve and retain authority over certain decisions during the transition to full decentralization. Critics identify single points of failure and potential regulatory vulnerabilities. The 2025 governance overhaul addressed some concerns by expanding voting rights and adding oversight of foundations, but the transition remains incomplete.

Network effects and liquidity fragmentation

Established chains attract liquidity and users more easily than new developments. Base was partially successful due to Coinbase’s existing user base. Smaller chains, even with superior technology, struggle to reach critical mass. The interoperability layer aims to address this issue by making liquidity accessible across the chain, but fragmentation remains a major challenge until it ships.

Application layer risks

Don’t eliminate Layer 2 security smart contract Vulnerability. The Moonwell Bad Debt Case (November 2025) highlighted the inability of infrastructure reliability to protect against oracle failures, economic attacks, and protocol bugs. Users must evaluate the risks of their applications independently of the security of the underlying chain.

What recent events are shaping the future of optimism?

Despite these challenges, technology upgrades and strategic partnerships were realized in late 2025, expanding capabilities and making incremental improvements to existing infrastructure rather than discontinuous pivots.

Performance: Flash Block

Flashblocks activation in September reduced pre-check time to 250ms. Applications now provide near-instantaneous feedback before a transaction is completed on Ethereum. Trading, gaming, and payment applications will benefit the most.

Institutional Infrastructure: Enterprise Revenue Stack

The October release of Morpho and Gauntlet is targeted at institutional users who want to: DeFi Increase profits with professional risk management. Companies and funds deploy capital across protocols using automated monitoring and compliance tools. Institutions can gain exposure to technical complexity without directly managing it.

Bitcoin integration

Build on Bitcoin Enables non-custodial BTC usage within Superchain applications. LayerZero’s December kBTC rollout brought tokenized Bitcoin to Ink, Unichain, and OP Mainnet. These integrations have pushed Bitcoin’s market cap to $2 trillion, attracting users who want DeFi access without selling their BTC holdings.

strategic partnership

THORSwap integration (November) enables cross-chain swaps between superchain assets and external ecosystems. The December rollout of Gauntlet will introduce institutional-level risk assessment to the protocol. These partnerships add functionality through integration rather than core protocol changes.

Roadmap for 2026

Three priorities: interoperability, performance, and economics.

An interoperability layer coming to testnet in early 2026 (mainnet expected in mid-2026) will enable atomic cross-chain transactions and allow applications to treat the entire superchain as a unified liquidity pool. Custom gas tokens allow chains to specify fees in stablecoins. Plasma implementations provide higher throughput for certain data types. PeerDAS distributes data availability requirements across a set of validators, reducing node operating costs.

Increased revenue will support the expansion of RetroPGF distribution. Our $250 million monthly goal reflects our confidence in generating sustainable fees from network activity.

What does optimism mean for the future of Ethereum scaling?

The practical question is not whether Layer 2 works, it is clear that it does…but which architectural approach best serves long-term ecosystem needs?

Optimism’s 15% share in cryptocurrency trading proves that there is a demand for affordable and fast transactions without abandoning Ethereum’s security guarantees. The superchain model provides a template of specialized chains that handle specific functions while sharing security and liquidity. This architecture is in contrast to monolithic chains that attempt to cover all use cases and sharded designs that are fragmented across complex coordination boundaries.

Institutional implementations through Base, Unichain, and Ink have demonstrated technical reliability. Large financial institutions select infrastructure based on uptime records, audit results, and operational performance rather than theoretical performance claims. 99.99% uptime and consistent block times meet professional standards.

Open source OP stacks deliver long-term network effects in exchange for short-term competitive advantage. Competitors becoming collaborators expands the total addressable market, rather than fragmenting it between incompatible platforms. As more chains join, access to shared tools and liquidity increases the value of the ecosystem for all participants.

Cross-chain composability through interoperability layers enables complex operations across multiple environments. This means Base collateral supports the utilization of Unichain while earning revenue on OP Mainnet. While these workflows remain impractical in isolated chains, they will become standard functionality in interconnected networks that share state awareness.

Horizontal scaling from specialized chains working together can outperform vertical scaling from a faster single chain. Five years in development and a $17 billion TVL suggests the bet is paying off.
