Since 2016, Maciej Baj has been a trailblazer in the field of blockchain interoperability, dedicating his full-time efforts to this complex and rapidly evolving technology. His journey began in earnest with a deep dive into sidechain development, where he not only honed his skills but also started to shape his vision for the future of blockchain technology.

Maciej's significant career milestone occurred in 2017 when he joined forces with Jacob Kowalewski, current t3rn’s Chief of Strategy Officer, at Lisk, a blockchain application platform. His work at Lisk, which included roles as Project Lead and Head of Development, was instrumental in nurturing his ideas. It was here, working on Lisk Core, that Maciej's vision for a multichain future began to take shape.

Over the years, Maciej's expertise deepened, particularly in the niche of building cross-chain bridging solutions. The challenges of interoperability, especially within single ledger platforms like Ethereum, fueled his interest in composability and reversibility — key concepts that would later form the bedrock of t3rn.

In 2020, recognizing that the blockchain industry was still grappling with the multichain challenge, Maciej, along with Jacob, made the bold decision to leave Lisk. This marked the start of a new chapter - the creation of t3rn. The platform, embodying the essence of web3 and the liberty to facilitate transactions across various blockchains, was a direct response to Maciej's question: "Why can’t cross-chain executions have the same characteristics as a single ledger execution, like on Ethereum?"

With a Master's in Computer Science, specializing in AI-based stylometric analysis and machine learning, Maciej brought a unique perspective to blockchain technology. His academic background played a significant role in shaping his approach to blockchain development, particularly in the areas of interoperability and smart contract functionality.

t3rn, under Maciej's leadership as the Founder and CTO, aims to create frictionless multichain smart contract execution, offering faster, cheaper, and more secure bridging to users. This initiative is central in empowering developers who are actively shaping the next phase of modular blockchains. Maciej's stewardship at t3rn exemplifies not just a commitment to technical excellence but also a vision to redefine how blockchain technology can be more accessible, efficient, and transformative for its community.

Drawing from his extensive experience as an open-source developer, Maciej has also been keen on solving the long-standing challenge of aligning contributions and rewards within the open-source community. This dedication led to the unique ecosystem dynamics at t3rn, where smart contract authors are recognized and compensated for their contributions, fostering a fair and incentivized environment.

Maciej's groundbreaking work has not gone unnoticed. In 2023, he was featured in the "Blockchain 35 Under 35 List," a testament to his significant contributions to the blockchain space. His leadership at t3rn continues to break new ground in blockchain technology, pushing the boundaries towards a more interconnected and efficient digital world.
