Scoped Capability Tokens for STVA
Scoped Capability Tokens are short-lived, revocable authorization tokens that grant specific actions, enhancing transaction security by eliminating broad approvals. They are designed to integrate with independent simulations and account authority lifecycles, supporting offline verification and revocation.

Post-quantum signatureless authorization with recursive verification
A new technique for signatureless authorization using proof-of-knowledge and recursive verification has been introduced, which is resistant to quantum threats. This approach involves publishing a commitment to a reusable secret and authorizing actions with randomized zero-knowledge proofs, addressing security challenges like safe reuse.
