[\[6\]](#cite-id-sLMobHnOz9) # Education Zarick graduated from the University of New Hampshire with a BS in Computer Science in 2009 and an MS in Computer Science in 2011. As a student, he worked in the UNH InterOperability Lab as a tester and a graduate research assistant alongside [Bryan Pellegrino](https://iq.wiki/wiki/bryan-pellegrino) and [Caleb Banister](https://iq.wiki/wiki/caleb-banister). [\[1\]](#cite-id-2e0mtm3gfg4) # Career At UNH, Zarick co-founded Coder Den, a software consulting firm, with [Pellegrino](https://iq.wiki/wiki/bryan-pellegrino) and Banister. After graduation, he served as CTO of Buzzdraft, an online fantasy sports website, until March 2013. In January 2018, he co-founded 80Trill, a [smart contract](https://iq.wiki/wiki/smart-contract) writing, testing, and auditing company, where he worked until March 2020. He also co-founded Minimal AI with [Pellegrino](https://iq.wiki/wiki/bryan-pellegrino), and in February 2021, they co-founded [LayerZero Labs](https://iq.wiki/wiki/layerzero). [\[1\]](#cite-id-2e0mtm3gfg4) # Interviews ## Quick Merkle Database In July 2025, on the How Things Work podcast, host Patrick O’Grady interviewed [LayerZero’s](https://iq.wiki/wiki/layerzero) Zarick, Issac Zhang, and Thomas Kim. They discussed the Quick Merkle Database (QMDB) and the Fast Ahead-of-Formation Optimization (FAFO). They introduced the research team at [LayerZero](https://iq.wiki/wiki/layerzero), which aimed to enhance decentralization in [blockchain](https://iq.wiki/wiki/blockchain) technology, emphasizing the importance of permissionless, censorship-resistant, and immutable systems. The conversation explored how QMDB, employing a log-based approach instead of traditional data structures, achieved significant efficiency in disk utilization and throughput, reaching up to a million transactions per second. They also detailed how FAFO's architecture optimized parallel processing by simulating transactions, using a unique polling system to minimize conflicts and maximize throughput while ensuring that the fundamental properties of [blockchains](https://iq.wiki/wiki/blockchain) were respected. The hosts concluded by reflecting on the ongoing research and potential applications of their findings, advocating for an accessible, decentralized future in [blockchain](https://iq.wiki/wiki/blockchain) technology. [\[7\]](#cite-id-K79ws0DMI7) ## LayerZero & Stargate In an interview with White Crypto at [TOKEN2049](https://iq.wiki/wiki/token2049) 2023, Zarick discussed his [crypto](https://iq.wiki/wiki/cryptocurrency) background and [LayerZero’s](https://iq.wiki/wiki/layerzero) [Stargate](https://iq.wiki/wiki/stargate-finance) bridge. He discussed his journey into the [crypto](https://iq.wiki/wiki/cryptocurrency) space after building and selling a previous company with his co-founders. They identified flaws in existing [blockchain](https://iq.wiki/wiki/blockchain) bridging solutions and developed [LayerZero](https://iq.wiki/wiki/layerzero), which allows for a decentralized communication protocol between [blockchains](https://iq.wiki/wiki/blockchain) using an ultra-light [node](https://iq.wiki/wiki/node) approach for security. They also implemented [Stargate](https://iq.wiki/wiki/stargate-finance), a composable asset bridge that enhances cross-chain transactions. Zarick emphasized a strong investment in security, with substantial funding allocated for audits and bug bounties. Highlighting the importance of stability in the [bear market](https://iq.wiki/wiki/bear-market), he expressed commitment to building tools that enhance the developer experience and interoperability across chains. The team's future plans included support for new [blockchains](https://iq.wiki/wiki/blockchain) based on developer demand, maintaining a focus on high-quality design and rigorous security standards throughout the development process.

The conversation centered on the efficiency of [Solana's](https://iq.wiki/wiki/solana) on-chain order book and its global execution capabilities, facilitated by the proof of history mechanism, which ensures synchronization among [nodes](https://iq.wiki/wiki/node). Participants also discussed the challenges and trade-offs faced while evolving [Solana's](https://iq.wiki/wiki/solana) system, particularly regarding the integration of [LayerZero](https://iq.wiki/wiki/layerzero) technology for cross-chain communication. They highlighted the importance of adaptable infrastructure to accommodate diverse use cases, ranging from [decentralized finance](https://iq.wiki/wiki/defi) to [NFTs](https://iq.wiki/wiki/non-fungible-token-nft), emphasizing the need for permissionless execution and scalability in the [blockchain](https://iq.wiki/wiki/blockchain) ecosystem. Overall, they envisioned a future where [Solana](https://iq.wiki/wiki/solana) serves as a primary hub for liquidity and transactions, streamlining exchanges across various platforms while maintaining a focus on performance and user experience. [\[8\]](#cite-id-uKDUkfyfLm) # Panels ## Cross-Chain Security Zarick's presentation on [LayerZero's](https://iq.wiki/wiki/layerzero) cross-chain security emphasized the necessity of robust cross-chain messaging protocols for [blockchain](https://iq.wiki/wiki/blockchain) applications. He highlighted the importance of composability among applications across different [blockchains](https://iq.wiki/wiki/blockchain), noting that no single chain can meet all application needs. Zarick detailed the risks associated with cross-chain messaging, such as client diversity, [smart contract](https://iq.wiki/wiki/smart-contract) upgradeability, and user application vulnerabilities, and explained how [LayerZero](https://iq.wiki/wiki/layerzero) mitigates these through immutable [contracts](https://iq.wiki/wiki/smart-contract) and optional library upgrades. He also introduced a security feature called "pre-crime," which allows applications to define invariants that prevent potential hacks during the asynchronous messaging process. [\[3\]](#cite-id-5clse6lcc4u) ## Omnichain Security Zarick presented “Pre-Crime: The Future of Omnichain Security” at the [DeFi](https://iq.wiki/wiki/defi) Security Summit 2022. He focused on two primary risks: protocol upgrade risk and user application risk. He highlighted how [smart contract](https://iq.wiki/wiki/smart-contract) upgrades can reset their security, making systems vulnerable, and emphasized the dangers of bugs in user applications built on messaging infrastructures. To mitigate these risks, [LayerZero Labs](https://iq.wiki/wiki/layerzero) introduced "Library upgrades," allowing applications to opt-in to new updates at their discretion, and "Pre-Crime," a technology that preemptively simulates and validates transactions on [forked](https://iq.wiki/wiki/fork) chains to prevent exploits. These approaches aim to enhance security and reliability in cross-chain communication. [\[4\]](#cite-id-6xpd8ia8tu5) ## The Multichain Future “The Multichain Future” panel at [TOKEN2049](https://iq.wiki/wiki/token2049) Singapore 2022 discussed the future of a multi-chain ecosystem, highlighting the importance and challenges of interoperability between different [blockchain](https://iq.wiki/wiki/blockchain) networks. Key speakers included Zarick from [LayerZero Labs](https://iq.wiki/wiki/layerzero), who explained [LayerZero's](https://iq.wiki/wiki/layerzero) protocol for cross-chain communication, and [Hart Lambur](https://iq.wiki/wiki/hart-lambur) from [UMA](https://iq.wiki/wiki/uma), who introduced their [optimistic](https://iq.wiki/wiki/optimistic-rollup) [oracle](https://iq.wiki/wiki/oracle) system. The conversation covered the trade-offs between different chains regarding speed, security, and use cases and the potential evolution toward applications operating across multiple chains. [Richard Muirhead](https://iq.wiki/wiki/richard-muirhead) from Fabric Ventures emphasized the need for clear use cases and the ongoing uncertainty in predicting which multi-chain configurations will dominate. The panel underscored the early stage of this technology and the importance of developing flexible, user-friendly solutions that can adapt to the emerging [blockchain](https://iq.wiki/wiki/blockchain) landscape.
