Multi-proof design in the OP Stack

With Bedrock, we built a system that can fit many types of proof schemes, providing a more flexible, secure, and future proof OP Stack for builders in the Optimism Ecosystem.

Building a Decentralized Identity Ecosystem, Together

Building a Decentralized Identity Ecosystem, Together

The Optimism Collective is building a better economic engine that fuels positive-sum games, and decentralized identity is central to that goal. Decentralized identity not only unlocks democratic governance and innovation, but also empowers individuals to have greater control over their finances and participate in the global economy on their own

Progressing towards decentralization: highlights from the Keys in Mordor summit

In February, OP Labs engineers and core developers from the Optimism Collective gathered in person for the Keys in Mordor summit. The goal for this summit? Figure out how to take Optimism’s upgrade keys to Mordor and safely throw them into Mount Doom, rendering the protocol technically decentralized. Attendees

Bedrock Security Reviews & Audit Competition

This article was written in collaboration with Maurelian. With the recent successful migration of the Optimism Goerli Testnet to Bedrock, we are approaching a crucial phase of the Bedrock release: the Optimism Mainnet upgrade. The size and complexity of Bedrock means that ensuring the security and stability of the system

Optimism’s Goerli Testnet is Migrating to Bedrock

After a year of intense research and development, Optimism has built the cheapest, fastest, most minimal codebase for an Ethereum-equivalent rollup, ever. We plan to bring this game-changing architecture to Optimism mainnet in an upgrade called Bedrock. To get ready for this release, we are migrating Optimism’s Goerli Testnet

EIP-4844: An Optimistic Bet on Rollup Scalability

EIP-4844 (protodanksharding) is on the rise. With its development, memes, and community support, it's anticipated as the next big upgrade to Ethereum. But what is it really? In a nutshell, it's a new transaction type that makes it easy to write cheap but ephemeral data on L1. The data, represented

Drippie: How Optimism automates Ethereum

Optimism does a lot of stuff on-chain. Managing and monitoring the many on-chain interactions required to keep a system like this running can become a bit of a headache. This isn’t an impossible problem — but it’s enough of nuisance that it’s worth automating.
