Abstract
If tokenized assets are to be a reality in the future decentralized Web3
then transaction keys need to be distributed and under the control of
the asset-owners. This requires a careful design of wallet systems based
on trusted hardware. A core feature needed for wallet systems is the
attestation of the state of the transaction keys in the wallet without
disclosure of the keys. This feature is relevant for relying parties
such as insurance providers who need to perform risk assessment based on
the security quality of the environment inside the wallet system that is
protecting the transaction keys. In the longer term, all key-bearing
devices that participate in a decentralized tokenized asset network will
need to be hardened using trusted hardware, with attestation
capabilities for detecting and countering cyberattacks.
