Centralized exchanges (CEXs) have quietly become significant distributors of onchain activity, according to a new analysis from Optimism. The shift represents a notable evolution in the crypto ecosystem. While decentralized exchanges (DEXs) were designed to eliminate intermediaries, CEXs have adapted by facilitating onchain transactions at scale. **Key developments:** - CEXs now process substantial volumes of onchain transfers and settlements - Traditional exchanges are bridging users to Layer 2 networks and DeFi protocols - The trend challenges assumptions about the CEX vs DEX divide This development suggests the future may involve coexistence rather than competition between centralized and decentralized platforms. CEXs bring regulatory compliance and user familiarity, while enabling access to onchain infrastructure.

Five major cryptocurrency exchanges—Coinbase, Kraken, OKX, Upbit, and Bitpanda—are operating on the same OP Stack blockchain infrastructure despite serving different products and markets. **Key figures:** - $495M in combined application revenue across these chains in H2 2025 - The OP Stack now supports 50+ chains processing 6B+ transactions, up from 200M transactions two years ago **What this means:** Multiple competing exchanges have adopted the same underlying blockchain technology stack, demonstrating the infrastructure's ability to support diverse business models while maintaining enterprise-level performance guarantees. Each exchange retains its own chain and revenue while benefiting from shared technical foundations.

**Over half of Fortune 500 companies are now exploring blockchain infrastructure**, with many choosing Optimism as their platform of choice. Kyle Jenke from Optimism explains the shift: enterprises are building next-generation financial products on the network, driven by three key factors: - Enterprise demand for blockchain solutions - The need for infrastructure ownership - New capital flows entering the space The trend signals a significant move toward institutional adoption of Ethereum-based infrastructure, with major corporations prioritizing scalability and stability in their blockchain strategies.

Optimism has launched a **four-week opt-in experiment** with stake-based priority ordering on OP Mainnet, running until June 23. **How it works:** - Participants stake 100,000 OP tokens into the PolicyEngineStaking contract - Stakers receive priority block positioning for their transactions - Non-participants continue using standard Priority Gas Auction (PGA) as usual **Key details:** - The experiment was approved by Optimism Governance earlier this month - After four weeks, OP Mainnet automatically reverts to standard PGA - The system was previously tested on Sepolia testnet **Resources available:** - [Official notice](http://docs.optimism.io/notices/stake-based-priority-ordering) - [Governance proposal](http://gov.optimism.io/t/upgrade-proposal-stake-based-priority-ordering-experiment/10655) - [Technical disclosure](https://docs.optimism.io/public/disclosures/stake-based-priority-ordering-disclosure.pdf) This experiment explores alternative transaction ordering mechanisms while maintaining backward compatibility for users who choose not to participate.

A new Ethereum experiment is testing transaction ordering based on staking behavior across two phases: **Phase 1 (Week 1)** - Eligible stakers' transactions ordered first-in, first-out (FIFO) - Staking above minimum threshold has no additional impact - Simple queue-based priority **Phase 2 (Weeks 2-4)** - Introduces stake-time weighted multiplier on priority gas - Longer staking duration + higher stake amount = higher multiplier - Maximum 3x advantage with diminishing returns - Designed to resist stake-rent attacks through time component **Key Parameters** - Up to 20% of blockspace reserved for experiment - Unused space flows back to normal transactions - Non-staking transactions remain unaffected - Fee market mechanics preserved The experiment aims to reward long-term stakers while maintaining network accessibility for all users.

**OP Mainnet is changing how transactions are ordered for the first time.** For years, the network's sequencer followed a single rule: transactions with the highest priority gas fees were processed first. Now, users have an alternative option. **Key changes:** - The traditional gas fee priority system remains available - A new ordering method is now live alongside the existing one - This represents the first of several planned sequencer experiments on OP Mainnet - Stake-based ordering is being introduced as an alternative mechanism **What this means:** Users can now choose between different transaction ordering methods rather than being limited to gas fee competition alone. The change aims to provide more flexibility in how transactions are prioritized on the network. This update marks a significant shift in OP Mainnet's approach to transaction sequencing while maintaining the existing gas-based system as an option.

**ExchangeOS** represents a significant development in making onchain trading infrastructure more programmable and accessible for developers. Built on the **OP Stack** - the same technology powering X Layer - the platform provides a scalable foundation for builders creating: - Perpetual futures (perps) - Prediction markets - Next-generation onchain applications This launch builds on OKX's previous work with X Layer and follows their partnership with Intercontinental Exchange to bring tokenized equities and U.S. futures to their 120 million user base. The move signals a broader trend of traditional exchanges evolving into comprehensive onchain financial platforms, leveraging Ethereum's infrastructure for programmable trading systems.

**Programmable financial infrastructure is changing how businesses operate.** Ben and Karl break down why companies are launching their own chains instead of relying on existing networks. **Key benefits:** - Direct connection to end users without intermediaries - Capital markets that operate at internet speed - New revenue streams from chain ownership - Value retention instead of fees flowing to third-party networks - Infrastructure becomes a business asset The shift represents a fundamental change in how enterprises think about blockchain - moving from using shared infrastructure to owning the rails themselves.

**Regulatory clarity is accelerating enterprise blockchain adoption in Japan.** Kyle Jenke discusses Mitsui's deployment on OP Mainnet, highlighting how supportive regulatory frameworks are making Japan a key market for institutional crypto adoption. **Key developments:** - Mitsui, a major Japanese conglomerate, has deployed on OP Mainnet - Japan's clear regulatory approach is encouraging enterprise movement into blockchain - The country's crypto accounts surpassed 11 million, demonstrating rapid adoption - Japan's pioneering regulatory framework is fostering safe and sustainable crypto growth The conversation with Genzio Co. emphasizes that when regulators actively encourage adoption rather than create barriers, enterprises respond with concrete deployments and infrastructure investments.

The OP Stack is enabling a new era of blockchain customization, according to insights from @karl_dot_tech. **Key Points:** - Customization allows blockchains to be tailored for specific use cases and requirements - The OP Stack provides the infrastructure to make this customization technically feasible - This represents the next significant wave of innovation in crypto development The ability to customize blockchains opens new possibilities for developers to create specialized solutions rather than one-size-fits-all networks.
