Summary:

This paper challenges the prevailing extremes of "native issuance" and "wrapped assets," arguing instead for a "Two-Layer Architecture" that separates the "vault" from the "record." It proposes that value should remain anchored in a regulated Asset Layer (off-chain custody), while the definitive record of ownership circulates on a public blockchain Ownership Layer (on-chain settlement). A regulated entity, the Token Operator, synchronizes the two, providing a framework that satisfies both the need for regulatory accountability and the desire for global, programmable settlement.

Key Points:

• Flaws of Native and Wrapped Assets: The paper critiques native issuance for creating illegal bearer instruments without identity or recourse, and wrapped assets for introducing dangerous bridge vulnerabilities.
• Separating the Vault and the Record: The core architectural proposal is to decouple custody from record-keeping; regulated intermediaries maintain the vault (custody, compliance), while the public blockchain becomes the single shared ledger for ownership.
• The Token Operator as Interface: A regulated entity called the "Token Operator" connects the two layers, functioning essentially as an issuer-CSD to maintain the definitive record of ownership on the shared infrastructure.
• Unhosted Wallets as Contingent Rights: The architecture resolves the unhosted wallet debate by treating them as holding "contingent rights"; wallets can transfer tokens freely, but holders must complete identity verification with the Operator to receive economic benefits like redemption or yield.
• Coexistence and Transition: The model allows for a gradual transition where traditional and tokenized forms of a security can coexist, with the Token Operator immobilizing legacy securities to mint tokens on the Ownership Layer.
