KEY TAKEAWAYS
- Arthur Breitman introduced xU308, a token on the Tezos blockchain, enabling direct ownership of uranium oxide.
- The xU308 token aims to democratize access to uranium markets, offering legal ownership without intermediaries.
- Tezos’ Etherlink, a non-custodial Layer 2 solution, supports xU308 by ensuring decentralized and efficient transaction processing.
- Breitman’s presentation highlighted blockchain’s potential to unlock real-world asset access, bypassing traditional market barriers.
Arthur Breitman, co-founder of Tezos, recently delivered a keynote at Consensus 2025, showcasing a groundbreaking application of blockchain technology. Wearing a t-shirt emblazoned with ‘I own uranium,’ Breitman introduced xU308, a token representing physical uranium oxide, available on the Tezos blockchain.
During his presentation, Breitman demonstrated a live, on-chain purchase of uranium, highlighting the practical application of blockchain in real asset tokenization. He emphasized that xU308 offers direct legal ownership of uranium, a commodity traditionally difficult to access due to high minimum trade requirements and over-the-counter market limitations.
Tokenization as a Bridge to Ownership
Breitman argued that tokenization serves as a bridge to real ownership and open markets, rather than a mere marketing tool. The xU308 token allows individuals to own uranium oxide with transparent custody and no asset management fees. This initiative aims to democratize access to uranium markets, which are increasingly relevant due to rising demand for nuclear energy driven by carbon reduction goals and AI infrastructure needs.
The keynote included a demonstration of the simplicity of purchasing uranium through xU308, emphasizing the token’s legal clarity and real-world backing. Unlike traditional investment vehicles such as ETFs or mining stocks, xU308 provides direct ownership without intermediaries, offering a fully digital and globally accessible solution.
Tezos’ Etherlink and Decentralization
Breitman also highlighted Tezos’ Etherlink, an EVM-compatible Layer 2 solution, as a key enabler of xU308. He contrasted Etherlink with other Ethereum rollups, which often rely on centralized control. Etherlink is designed to be non-custodial, ensuring fairness in transaction ordering and avoiding central points of failure.
Transactions on Etherlink are confirmed in under a second, with finality reached in approximately 16 seconds, making it suitable for real-time markets. This infrastructure supports projects like xU308, enabling the tokenization of real-world assets without compromising on decentralization or performance.
Breitman’s presentation at Consensus 2025 was not just a theoretical exploration but a demonstration of a working, permissionless product. The xU308 token exemplifies how blockchain can unlock access to real-world assets, bypassing traditional barriers such as legal restrictions and intermediary fees.

Why This Matters: Impact, Industry Trends & Expert Insights
Tezos has introduced the xU308 token, representing physical uranium oxide, aiming to democratize access to uranium markets through blockchain technology.
Currently, blockchain asset tokenization is experiencing significant growth across various industries. In real estate, tokenization is transforming property investment by enabling fractional ownership and increasing liquidity in traditionally illiquid markets. This aligns with Tezos’ initiative to tokenize uranium, providing a new avenue for investment in a traditionally inaccessible market. Deloitte
Expert opinion on uranium tokenization via blockchain centers on its transformative potential for accessibility, liquidity, and transparency in a traditionally opaque and high-barrier market. This supports Tezos’ efforts with the xU308 token to open uranium markets to a broader audience and enhance market efficiency. CryptoSlate
