Original Author: Four Pillars
Original Compilation: Ken, ChainCatcher
Key Summary
Base announced it will transition from Optimism's OP stack to a proprietary unified architecture, delivering a strong shock to the market and significantly impacting
$OP price.
Optimism's code is fully open source under the MIT license, and it implements a revenue-sharing model for chains joining the "Super Chain." Arbitrum adopts a "community source" model, requiring chains built on Orbit that settle outside the Arbitrum ecosystem to contribute 10% of their revenue.
