Can smart contracts make real-world assets more valuable?
Jason Teutsch, Truebit
Abstract. Tokenization has experienced a revival with estimates touting projected value of the global, tokenized real-world asset (RWA) market in trillions of dollars. The future of RWA depends on verification. Indeed, verifiable information mitigates risk, which increases asset value. Put another way, some classes of assets do not yet exist due to excessive overhead or risk for investors. From a more technical point-of-view, this is the TRU story of how I tried to divest from smart contracts and learned to love the ledger. In order to realize the economic value of smart contracts, it actually pays to strip away the economic aspects of this so-called “programmable money.” Join me on a proof-by-example adventure. - 15:30 - 17:00 CoDecFin Workshop
Interactive workshop session: Crypto-Agility and PQC migration for Blockchain
Abstract. As the importance of preparing blockchain infrastructures for the post-quantum era intensifies, discussions on migration strategies toward PQC-resistant systems have become increasingly critical. Building on the momentum of the March 3rd BGIN session—which highlighted the need for resilient migration paths for existing chains (meeting report)—this closing roundtable at CoDecFin25 will provide a forum to examine key requirements for quantum-resistant blockchains, explore practical transition mechanisms, and deliberate on future directions for standardization. The session will also serve as a natural continuation of the NIST Crypto-Agility Workshop held the previous day (agenda), reinforcing the global momentum behind cryptographic agility and PQC adoption.
