What is the security end-game for tokenized RWAs?

Ultimately, the desired security property is to have an end-to-end trust path between the real world and the blockchain, but while this is conceptually simple to understand it is non-trivial to achieve due to the prevalence of commodity computing systems.

What upcoming technologies will help bridge the RWA trust gap?

As the nature of RWAs necessitates the transfer of off-chain information on-chain, Trusted Execution Environment (TEE)-based oracles will play a crucial role in minimizing the risk of attackers compromising the oracle service. Additionally, other methods are also being explored, such as measuring the invariant and intrinsic properties of each asset to test and verify their authenticity, and inscribing unmodifiable keys through a micro-3D printing process to prevent counterfeiting. However, the above technologies are still in their infancy and not ready for commercialization.

What is the best interim security and trust solution for RWAs?

Until the technologies mentioned above are ready, the next best solution is to rely on institutional trust to complete the end-to-end trust path for tokenized RWAs. For this to work, three criteria need to be met: the institution needs to be sufficiently trustworthy, every step of the trust path must be carefully evaluated for even the smallest flaws, and stakeholders and users must be made fully aware of the institutional trust that they are relying on.
