In this episode of Composable, hosts Alysia and Ellie speak with Orest from t1 about proof aggregation, TEEs (Trusted Execution Environments), L2 security, and how these concepts relate to finality. The conversation explores Vitalik Buterin's recent post proposing a "two out of three" proof system combining TEE proofs, ZK proofs, and Optimistic proofs to enhance blockchain security while improving finality times. Orest also shares how t1 is implementing TEEs to achieve faster finality times for L2s while maintaining strong security guarantees.Key Topics Covered:Introduction to TEEs and how they workComparison between TEE proofs and ZK proofsVitalik's proposal for combining multiple proof systemsHow t1 uses TEEs for integrity rather than confidentialityRemote attestation process and its importanceSecurity considerations and risk models for TEEst1's unique approach combining TEE proofs with periodic ZK proofsThe challenges of vendor centralization in TEE ecosystemsReal-world tradeoffs between security, speed, and usabilityComposable is a bi-weekly podcast exploring crypto's building blocks.

Who Secures Crosschain Messages?
In this episode of Composable, Alysia and Ellie explore the security of crosschain messages. They examine notable bridge attacks, analyze what makes crosschain messages vulnerable, and discuss various security approaches, including multisigs and Trusted Execution Environments (TEEs). The episode breaks down the technical aspects of securing crosschain messages while considering the trade-offs between speed and usability.Key Topics Covered:Notable bridge attacks like Ronin, Wormhole, and OrbitThe anatomy of crosschain messagesSecurity vulnerabilities in bridge systemsMultisig security models and their limitationsTrusted Execution Environments (TEEs) and their role in securing crosschain messagesTrust assumptions in various other security approachesComposable is a bi-weekly podcast exploring crypto's building blocks.

Unpacking Intents with Hyperlane's Eda Akturk
In this episode of Composable, hosts Alysia and Ellie speak with Eda Akturk, a developer advocate at Hyperlane, about intents in general and the recently released Open Intents Framework, specifically. They explore what intents are, how they're changing user experiences in web3, and dive into the collaborative effort behind the Open Intents Framework, which aims to make it easier for developers to build intent-based applications.Key Topics CoveredHow to define intents in a blockchain context (eg, allowing users to specify their goal rather than know how to reach it themselves)The Open Intents Framework, a collaborative effort led by Hyperlane, Bootnode, and the Ethereum FoundationHow the framework builds upon the ERC-7683 standard proposed by Across and UniswapThe framework's three main components: smart contract base, open-source solver implementation, and ready-to-use UIThe mechanics of intent transactions and how solvers fulfill user requestsHow solvers front liquidity and manage finality risks when bridging between chainsTarget audiences for the Open Intents Framework, especially new chains and crosschain applicationsBenefits of standardization for creating composability between different intent systemsThe competitive solver market and how it leads to better UXThe future vision for intents in the blockchain ecosystemThe unusual level of cooperation between competing L2s and infrastructure projectsComposable is a bi-weekly podcast exploring crypto's building blocks.

Is Synchronous Composability Overrated? With special guest, Cecilia from Gwyneth Taiko
In this episode of Composable, hosts Ellie and Alysia dive deep into the topic of synchronous composability with guest Cecilia, an engineer at Gwyneth Taiko. They explore the technical challenges of reaching synchronous composability, potential implementations to enable it, and the future value it could drive. They also examine why many prominent figures in the crypto space consider synchronous composability overrated...Key Topics Covered:Synchronous vs. asynchronous composability in blockchain systemsTechnical challenges of implementing synchronous composability across different L2 chainsGwyneth's successful demo of synchronous composability within their clusterThe advantages of based rollups for achieving synchronous composabilityShared sequencing and why many chains resist implementing itPractical applications of synchronous composability, particularly for L2s accessing L1 liquidityThe "one big rollup" critique and why having multiple chains with shared sequencing still makes senseComparison of synchronous composability with intent-based approaches to cross-chain interactionsThe potential future of domain-specific chains using based infrastructureHow preconfirmation protocols like Espresso could enable faster synchronous interactions between chainsComposable is a bi-weekly podcast exploring crypto's building blocks.
