Measuring Impact Is Hard We all love a good story, especially in crypto, where rapid change and open data make it easy to find patterns and draw conclusions. An incentive program launches, and new addresses follow. A protocol upgrade goes live, and usage spikes. It’s tempting to attribute any| OP Labs Blog
Security roles in crypto need steady, methodical work. Figuring out the safety of a complex protocol is genuinely challenging, and effective threat modelling is a structured way to spot weak points early so you can fix them. It's a straightforward process that taps into what engineers and business folks know| OP Labs Blog
Optimism is extending its $2 million bug bounty program to cover proposed protocol upgrades before they ever go into production, as OP Stack core developers prepare to roll out native interoperability to the Superchain. The proposed Upgrade 16 to the OP Stack is now live as the first upgrade proposal| OP Labs Blog
Relayer.sol brings first class multichain end-to-end testing to your Forge testing setup. By inheriting from the abstract Relayer test helper, your tests can spin up forks of multiple networks, emit real L2ToL2CrossDomainMessenger events, and relay them inside the same forge test process — no external relayer or scripting glue required.| OP Labs Blog
We recently ran PeerDAS through its paces on a modified peerdas-devnet-7 testnet (big thanks to EthPandaOps for leading the spec work!). This devnet was run by Sunnyside Labs, a core development team in the Optimism Collective, to benchmark how well different combinations of execution and consensus layer clients handle blob| OP Labs Blog
Why Metrics Matter Like any business, the Superchain needs clear success metrics to evaluate performance and guide strategic decisions. Defining success in crypto is challenging. There’s constant debate over the “best” metric, often because people are optimizing for different goals, values, or timeframes. This disconnect creates confusion and makes| OP Labs Blog
This post kicks off a multi-part series on PeerDAS. Over the coming weeks we’ll publish performance deep dives for every major consensus layer /execution layer (el/cl) client pair, surfacing how each stack performs in preparation for the upcoming Fusaka upgrade. The Ethereum Foundation recently outlined its priorities| OP Labs Blog
