Agreement: Liquefaction: Privately Liquefying Blockchain Assets

Record: kaal:position:2026-09-29-001 · 2026-09-29

Fábrega and coauthors demonstrate that formal non-transferability does not by itself preserve one-person-one-account control. TEE-based key encumbrance can let one actor rent or direct voting rights across identity-verified wallets without transferring the underlying credential. The result supports the narrower proposition that Sybil resistance also requires control-binding assumptions or countermeasures; it does not show that every non-transferable identity design fails.

Affirmed commentary position. This record extends a source-bound scholarly claim but is not a verbatim paper claim.

Holds when

TEE-based key encumbrance is available
wallet or credential control can be rented or delegated
the protected claim is treated as a negative sufficiency proposition
