How L1 and L2s can build the strongest possible Ethereum

From blog.ethereum.org

Over the last 5 years an ecosystem of chains has grown up around Ethereum L1. There are many different properties these chains can choose to extend from Ethereum: some inherit full decentralization (e.g. Stage 2 rollups), some inherit a subset of the security properties (e.g. validiums, prividiums), and some simply build on the common EVM standard (without being an L2). Many are still under development, often beginning as independent chains and gradually integrating more deeply with Ethereum L1. It is time for the EF and the broader Ethereum ecosystem to update our model of how Ethereum L1 and this network of L2s ... (full story)
