Layer 2 scaling solutions are widely regarded as the next step forward in the mainstream adoption of crypto as they enable higher throughput and lower transaction fees. Coinbase’s recent announcement of building an optimistic rollup solution called Base is proof (no pun intended) that major centralized actors view this as an opportunity to onboard new users in a decentralized crypto economy. The following years will abound in innovation as both optimistic and zero-knowledge rollup solutions still have plenty of room to grow, but the involvement of centralized entities will act as a catalyst from a technological, as well as a regulatory standpoint.We were joined by Jesse Pollak, Head of Protocol at Coinbase, to discuss the thesis & business model behind Base and how it will act as an interoperable bridge to onboard the next billion users on-chain.Topics covered in this episode:Jesse’s background and his role as Head of Protocol at CoinbaseBase’s business model & thesisBuilding on the Optimism stackPermissionlessnessHow regulations are going to influence users of Base (vs. Coinbase)Learning from the competition (BSC)Different fee markets to offset transaction costsWhy Base chose the Optimism stackBase’s upgradeabilityTackling Optimism’s withdrawal periodBootstrapping BaseFuture roadmap and mainnet timelineEpisode links: Jesse Pollak on TwitterBase on TwitterCoinbase on TwitterOptimism on TwitterSponsors: Omni: Access all of Web3 in one easy-to-use wallet!
