An update on OP Labs’ goals for advancing Optimism’s technical decentralization.

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

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

Gitcoin’s new grants protocol is actively under development and, as of this writing, currently in an alpha testing phase. The details in this blog post reflect the latest information at the time of writing, and could change as the alpha test season progresses. You can keep track of the

Alpha leak: today marks the start of the beta for the Optimist NFT, a customizable profile picture project meant to represent user identity across the Optimism Ecosystem. Coming soon to a Collective near you! 👀 The Optimist NFT is one of the first applications built on top of the AttestationStation, a

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

Open source and public goods are at the heart of Optimism’s ethos. In alignment with our goal to decentralize Optimism, we plan to open source more and more pieces of the Collective. Today, we are very excited to publish our Figma library, Pragmatism, to the Figma community. Anyone will

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.

Guiding new users to their first transaction on Optimism.

💡Note: Optimism Kovan has been decommissioned as of 10/5/2022.The Kovan testnet has been deprecated by the Ethereum community, with only two validators remaining. To avoid disruptions on a network that is no longer actively maintained, we’ve started the process of migrating our testnet from Optimism Kovan

Bedrock is the cheapest, fastest, and most advanced rollup architecture. Ever. 💡Read up on the specific changes to Optimism Mainnet for developers coming with the Bedrock release here [https://community.optimism.io/docs/developers/bedrock/].Optimism has always tried to stay on the cutting edge of rollup architecture. Last year,

In the beginning, mainnet.optimism.io [http://mainnet.optimism.io] was just a domain alias. All the actual infrastructure was handled by QuickNode. This let us focus on developing the core protocol without worrying about how users could access the network. As we grew, we realized we needed more than

Solidity devs: meet Smock v2 [https://github.com/defi-wonderland/smock]. The S olidity mocking library. A collaboration between Optimism [https://twitter.com/optimismPBC] and the fantastic team over at DeFi Wonderland [https://twitter.com/DeFi_Wonderland]. Smart contract testing has historically been… hard? If not hard, then just confusing. Way

Dearest Etherscan, How to describe what you mean to us? Let us count the ways. You are… * The stable provider of knowledge. * The humble watcher of the realm. * The telescope with which we marvel upon the decentralized heavens. * The bedrock on which the house of DeFi stands. * The quiet knight

This is the story of our experience looking into a bug that caused our Optimistic Ethereum testnet deployment [https://community.optimism.io/docs/developers/networks.html#optimistic-kovan] to stop accepting new L1 ⇒ L2 deposits for a period of several days in the early days of June 2021. For some context,
