OP Sepolia Launches Phase 2 of Stake-Based Transaction Ordering Experiment
OP Sepolia Launches Phase 2 of Stake-Based Transaction Ordering Experiment
🧪 OP's ordering experiment evolves
Optimism's testnet OP Sepolia has entered phase 2 of its stake-based transaction ordering experiment, introducing a new multiplier system that combines three factors into a single ordering score:
- Stake size
- Stake duration
- Priority gas
The formula: effectivePriorityGas = priorityGas × m_total(S, t)
Key features:
- Capped at 3x maximum advantage
- Resistant to stake-rent attacks through time penalties on flash borrowing
- Non-staking transactions remain unaffected
This represents the first in a series of planned sequencer experiments for OP Mainnet, designed to enable programmable block-building tailored to enterprise performance and policy requirements.
The Stake-based transaction ordering experiment on OP Sepolia is entering phase 2. What this means - Phase 2 introduces a multiplier that blends stake size, stake duration, and priority gas into a single ordering score. effectivePriorityGas = priorityGas × m_total(S, t) Key
We're experimenting with how transactions are ordered on OP Mainnet — for the first time ever. Stake-based transaction ordering is live on Sepolia today. Stake OP, get top-of-block access. Here's what's happening and why 🧵
ether.fi Migrates 70,000+ Cards and $220M TVL to OP Mainnet
**ether.fi completes major migration to OP Mainnet** The largest non-custodial crypto card by spend volume has moved its entire operation to OP Mainnet, bringing: - 70,000+ active cards - 300,000+ accounts - $220M+ in total value locked (TVL) **Why OP Mainnet?** The infrastructure offers compelling advantages: - $0.00001 median transaction fees - Sub-250ms finality via Flashblocks - 99.99% uptime year to date **What's next** The migration unlocks future features including increased cashback rewards, native stablecoin support, and deeper on-chain liquidity. Users can continue using Stake, Liquid and Cash services without disruption.
OP Stack Powers 43% of Ethereum Layer 2 Activity Across 50+ Chains
FalconX's institutional research desk released comprehensive analysis of the OP Stack's growth and market position. **Key Metrics:** - 50+ chains now built on OP Stack - 6 billion transactions processed in 2025 - 43% of all Ethereum Layer 2 activity The OP Stack, originally developed by Optimism (formerly Plasma Group), has evolved from a single Layer 2 solution into the foundation for the Superchain - a network of interconnected chains. Teams building on OP Stack, including Base, share revenue with the Optimism Collective and gain access to benefits like Retro Funding and growth incentives. The open-source approach has positioned OP Stack as the leading infrastructure for Ethereum scaling solutions.
Four Pillars Report Examines Privacy Boost's Institutional-Grade Privacy on OP Stack
A new report from Four Pillars analyzes **Privacy Boost**, the first privacy solution built on the OP Stack. The report explores what constitutes institutional-grade blockchain privacy and how Privacy Boost addresses these requirements. **Key highlights:** - Privacy Boost represents the first privacy-focused implementation on Optimism's OP Stack infrastructure - The solution aims to meet institutional standards for blockchain privacy - Four Pillars provides detailed analysis of the privacy mechanisms and their applications The report comes as institutional adoption of blockchain technology continues to grow, with privacy remaining a critical concern for enterprise users. Privacy Boost's integration with the OP Stack suggests growing attention to privacy features within the Ethereum scaling ecosystem. Read the full Four Pillars report for technical details on institutional-grade privacy implementation.
Alchemix v3 Launches on OP Mainnet with 90% LTV Vaults
**Alchemix v3 is now operational on OP Mainnet**, marking a significant upgrade to the protocol. **Key features include:** - Mix-Yield Tokens for diversified yield strategies - Fixed-Duration Transmuter for predictable debt repayment - 90% loan-to-value (LTV) vaults, allowing users to borrow more against their collateral The deployment on Optimism's layer-2 network aims to provide users with faster transactions and lower fees while maintaining Ethereum security.
