In this episode of Composable, hosts Alicia and Ellie dive deep into the world of blockchain confirmations, exploring the nuances between preconfirmations, confirmations (like those provided by the Espresso Network), and L1 finality. They unpack how these different levels of transaction verification impact user experience and interoperability.
Key topics covered:
- The emergence and evolution of preconfirmations, particularly in relation to based sequencing, and how they differ from BFT confirmations
- The role of centralized vs. decentralized sequencers and their impact on trust assumptions
- How preconfirmations affect cross-chain interoperability
- The trade-offs between user experience and security when using different confirmation types
- The future of execution preconfirmations and shared sequencing
- The impact of MEV (Maximal Extractable Value) on preconfirmation systems
- Discussion of real-world implementations, including Arbitrum and Optimism
- The relationship between Data Availability (DA) layers and preconfirmations
- Analysis of "based rollups" and their implications for blockchain architecture
Whether you're a blockchain developer, crypto enthusiast, or simply curious about the technical foundations of web3, this episode offers valuable insights into how transaction confirmations are shaping the future of blockchain infrastructure.
