1. The teenage years of Bryan Pellegrino
Bryan Pellegrino’s story begins not in the world of technology, but at the poker tables. Starting at the age of 15, Bryan was already playing online poker—years before he was legally allowed to gamble. His father helped him set up an account, and what began as a teenage hobby quickly turned into a career. Over the course of more than a decade, Pellegrino honed his skills to become one of the top players in the world, earning over $500,000 in World Series of Poker purses alone. By 2014, he was not only a master of the game but also at a crossroads.
After countless hours spent grinding online poker, Pellegrino began to feel disillusioned. The thrill of victory faded as he realized that the game had become monotonous. Although he had achieved significant financial success, he felt as though poker was a dead-end. “Once I got there, I realized, hey—there’s no leverage. There’s no anything,” Pellegrino recalls. This realization led him to look for new challenges, ones that offered more meaningful and impactful rewards beyond just financial gain.
2. Transition to Blockchain and Founding LayerZero
In the wake of his poker career, Bryan Pellegrino redirected his focus toward the rapidly evolving world of technology, particularly blockchain. His deep understanding of complex systems, honed through years of strategic thinking in poker, gave him a unique advantage as he ventured into blockchain development.
Pellegrino’s breakthrough came when he co-founded LayerZero Labs with Ryan Zarick and Caleb Banister, two best friends and fellow computer science researchers from the University of New Hampshire. LayerZero was born out of a pressing need in the blockchain space: interoperability. The goal was to solve one of the most fundamental and challenging problems in blockchain technology—enabling different blockchains to communicate with one another seamlessly, securely, and at minimal cost.
LayerZero was not created as a traditional blockchain bridge. Instead, it focused on building a new kind of messaging layer, one that could facilitate communication across multiple blockchains—whether Layer 1 or Layer 2. This would allow for the transfer of data, assets, and information across chains without the cumbersome fees and security risks that come with traditional blockchain bridges.
3. The LayerZero Solution
Before LayerZero, moving data between blockchains was both expensive and risky. Existing solutions required users to navigate complex and often insecure blockchain bridges. These bridges, which relied on a series of centralized servers, were vulnerable to attacks. In fact, in 2021, cryptocurrency hacks resulted in losses exceeding $14 billion, highlighting the need for more secure methods of transferring assets across chains.
Pellegrino and his team set out to fix this by creating a more robust and efficient protocol. LayerZero’s design was centered around a lightweight messaging system that could securely and cheaply facilitate cross-chain transactions. This innovative protocol would form the backbone of Web3, where decentralized applications (dApps), finance, gaming and other services could communicate freely across blockchain ecosystems.
In essence, LayerZero provides a universal communication layer for all blockchains, allowing developers to integrate their applications across multiple networks. This makes it easier for users to send information and transfer assets without the hassle of paying high transaction fees or worrying about security issues.
4. Recognition and Growth
LayerZero's innovation caught the attention of major investors, including Sequoia Capital. In 2022, following a successful Series A+ funding round co-led by Sequoia, the company raised $135 million to accelerate its vision of a decentralized future. Bryan Pellegrino’s leadership and his vision for a unified blockchain ecosystem were pivotal in attracting such high-profile backers.
Sequoia’s Shaun Maguire, who has been tracking blockchain technology since the late '90s, described LayerZero’s technology as the “glue of crypto.” He emphasized that LayerZero was more than just a protocol—it was a critical component that connected the various pieces of the crypto ecosystem, creating a more valuable and cohesive network.
Today, LayerZero stands as one of the most promising projects in the blockchain space, helping to enable the growth of Web3—the next generation of the internet. With the ability to send information between blockchains quickly, cheaply, and securely, LayerZero is making it easier for decentralized applications to flourish. As Bryan Pellegrino puts it, the project represents the “Holy Grail” of blockchain technology, solving a critical challenge that could propel Web3 into the mainstream.
The journey from poker champion to blockchain pioneer is a testament to Pellegrino’s relentless pursuit of innovation. Just as he once mastered the art of reading people and strategies at the poker table, Pellegrino has now turned his attention to solving one of the most intricate and high-stakes problems in the blockchain space. His work with LayerZero is paving the way for a decentralized internet where users and applications can seamlessly interact across different blockchain platforms.

5.1 About LayerZero
At ETHDenver 2022, Bryan Pellegrino, CEO of LayerZero Labs, addressed the challenges and solutions in building cross-chain and multi-chain applications. He identified systemic risks in current cross-chain solutions, particularly those relying on a central consensus mechanism. These solutions are vulnerable to exploitation if compromised. Pellegrino emphasized the importance of customizable security parameters tailored to the specific needs of each application, rather than a one-size-fits-all approach. He advocated for a modular system, where security decisions are made at the application layer. This would help mitigate systemic risks while enhancing capital efficiency. Additionally, Pellegrino highlighted the shift in the blockchain industry from focusing solely on value transfer to addressing broader messaging and synchronization needs across different blockchains.
5.2 Cross-Chain Evaluation and Security Principles
During Crypto Startup School 2023 (CSS 23), Pellegrino delved into the growing landscape of cross-chain messaging protocols and the broader challenges of building secure protocols in the blockchain space. He acknowledged the rapid expansion of cross-chain communication, yet warned of centralization issues that could undermine security. Pellegrino discussed the trade-offs between performance and security and laid out three foundational principles for successful blockchain protocols: immutability, permissionlessness, and censorship resistance. Using examples like Uniswap and Ethereum, he demonstrated the risks and necessary considerations for secure protocol design, underscoring the importance of these principles in ensuring security and fostering user trust.
5.3 Connecting Subnets with LayerZero
At the Avalanche Summit 2022, Pellegrino showcased how LayerZero could be used to connect Avalanche subnets, stressing the importance of generic messaging over simple value transfers for more complex applications. He explained the need for seamless messaging between chains to eliminate inefficiencies, such as requiring each project to develop its own infrastructure. Pellegrino emphasized that LayerZero provides a foundational messaging layer, enabling blockchain networks to deploy their own bridges without dealing with the associated security and maintenance challenges. He also introduced Stargate, a new type of bridge utilizing native asset pools to facilitate liquidity transfers. Pellegrino highlighted the diverse use cases for LayerZero, extending beyond DeFi to include areas like gaming
6. Conclusion
Bryan Pellegrino’s path from poker tables to the cutting edge of blockchain technology is a unique and inspiring story of adaptability, vision, and innovation. Through his leadership at LayerZero Labs, he is not only shaping the future of blockchain interoperability but also playing a pivotal role in the development of Web3. As the CEO of LayerZero, Pellegrino continues to push the boundaries of what is possible in the decentralized world, offering solutions to complex problems that could reshape the digital landscape for years to come.
With the continued growth of LayerZero and the broader Web3 ecosystem, Bryan Pellegrino’s influence is sure to be felt for years to come, cementing his legacy as one of the key figures in the blockchain revolution.
