Medium to Mirror
From now on we’ll be using Mirror as our primary publishing platform. — As Optimism continues to grow so do our communication needs. We’ll continue to keep you informed of all the amazing developments here at Optimism from our Twitter and optimism.mirror.xyz, both of which now belong to the newly created Optimism Foundation. We look forward to doing so from a platform that reflects our shared values of permissionlessness and decentralization. OP Labs also has a dev blog for more technical and engineering-focused content.
