Making Sense of Based Rollups on Bankless

Rollups depend on Ethereum for security and decentralization , while Ethereum depends on rollups to expand the economic activity of the ecosystem .

However, L1 settlement alone is an incomplete picture of what the rollup-centric roadmap aims to accomplish. Ethereum also serves as an affordable settlement and DA layer for rollups. I see rollups (and their corresponding rollup platform à la Optimism Superchain and Arbitrum Orbit) as independent fiefdoms. Each platform will compete to give users ... See more

There are clearly differences, but they have the same general shape. Let’s take it a step further. What if you wanted stronger pre-confirmations on your rollup (assume this is not a based rollup) rather than a centralized sequencer. Well then you may implement a PoS sequencer set, reintroducing economics that again look even closer to an L1. Or, wh... See more

Since the advent of Optimistic Rollups (ORUs) and Zk-Rollups (ZRUs), the paradigm has changed.Computation is run off-chain by high-end machines (the provers) while posting a fraud proof (on ORUs) or a validity proof (on ZRUs) on a settlement chain, which can prove the computation integrity, or in other words, that the computation has been executed ...

Interestingly, Ethereum’s rollup-centric roadmap is implicitly a gambit in this direction. ETH is sacrificing REV to its L2s rather than capturing it all to itself, in return for spreading the moneyness of ETH the asset. It’s unclear if its L2s will win out, or if they’ll continue to aggressively use and spread ETH in the future, but it’s clearly t... See more

1. Privy makes it easy to embed wallets that users control but don’t need to think about, right in the app.


2. Base , Coinbase’s EVM-Compatible Layer-2 network, is a cheap, highly performant L2 with the trusted reputation and brand of Coinbase. (Since launching in August 2023, Base has already made upgrades that make the network cheaper and faster, whi

If the L2 is an Ethereum rollup and posts transaction data to Ethereum blobs, the escape hatch is available for use unconditionally. Because the data behind each state update on the bridge is committed to on an Ethereum blob, rollup users are guaranteed the ability to prove the validity of their withdrawal and get it included utilizing an L1 transa

If you're a developer building decentralized applications, you have been faced with uncomfortable tradeoffs in choosing how to manage data. The two available options available have held back Web3 apps:Option 1 has been to use a smart contract (blockchain-based) backend and a static frontend. The downside of this option is that these apps are not ve... See more
