- Minting NFTs from Ethereum or OP Mainnet
- Lessons in Causality: Measuring Impact in the Superchain Ecosystem
The article argues that observed changes in crypto metrics, such as new addresses after an incentive or usage spikes after an upgrade, cannot be attributed to an intervention without a structured causal approach. It describes selection bias and the need for counterfactuals, and recommends experiments where feasible and quasi-experimental methods otherwise. Its examples include an Optimism airdrop analysis using regression discontinuity, which estimated a 4.2 percentage point increase in 30-day retention and 2.8pp in 60-day retention for addresses receiving airdrop 5 versus similar addresses that did not, and an Open Source Observer synthetic control study of Retro Funding.
- Solving Interoperability for the Superchain and beyond
The article presents a plan to build native interoperability into the OP Stack so that chains in the Superchain, and eventually broader Ethereum, can move assets and data without routing through L1 Ethereum. It says current cross-chain transfers rely on L1, which is expensive and slow, and that interop mainnet is planned for next year with transfers completing in under 2 seconds within a single block. The design includes a message passing protocol, the SuperchainERC20 token standard, a shared interop fault proof, and an initial interoperable chain set of OP Mainnet, Mode and Base.
- PeerDAS and a 48 blob target in 2025
PeerDAS (EIP-7594) is presented as the step that lets Ethereum scale to at least a 48 blob target per block, an eightfold increase in blob capacity over the current 6-blob target. Under the approach, nodes no longer download all blob data; instead, each full node downloads and verifies a small, randomly assigned portion and relies on sampling, with each validating node custodying 8 data columns. The article says this raises throughput from about 220 to about 3,500 UOPS without adding node storage or bandwidth requirements, and it notes that the 768 kB per-block storage figure matches today's requirement. OP Labs says it is collaborating with Sunnyside Labs, Base, and Soneium ahead of the Fusaka upgrade, which it targets for later this year.
- A novel account abstraction RPC endpoint for conditional inclusion of UserOps
- Feature-complete fault proofs are live on OP Sepolia
The feature-complete OP Stack fault proof system launched today on OP Sepolia, the primary testnet for OP Mainnet, and supports an incentive-compatible bonding mechanism and permissionless validation. The release lets anyone challenge and remove invalid withdrawals of ETH and ERC-20 tokens without a trusted third party, and it adds a framework through which additional proof systems, such as Asterisc, can plug into existing smart contracts. The article presents this as a step toward Stage 2 decentralization and "multi-proof nirvana," where Optimism would no longer rely on a security council. Breaking changes affecting bridges, CEXs, and custom withdrawal solutions also ship with the upgrade, and the MVP was first shipped in October 2023.
