In this episode of Composable, Ellie and Alysia dive deep into one of blockchain's most critical yet confusing concepts: finality. Triggered by a real-world story of someone losing funds due to misunderstanding finality in crosschain transactions, they explore the nuanced definitions of finality, settlement, and confirmations across different blockchain layers.The discussion reveals how finality is not a fixed concept but rather depends on trust assumptions, application requirements, and the observer's perspective. They examine how different stakeholders, from centralized exchanges to DeFi protocols, make trade-offs between speed and security when defining finality for their users.Key topics covered: Defining blockchain finalityFinality vs settlementLayer 2 finality considerationsCrosschain composability challengesReal-world application examplesDeveloper trade-offs and decisionsConfirmations and block timesVariable finality factorsComposable is a bi-weekly podcast exploring crypto's building blocks.
