How to Achieve 'Exclusive Control' Under UK ETDA 2023?
The UK Electronic Trade Documents Act 2023 (ETDA) has revolutionized global trade finance by granting electronic trade documents the exact same legal functionality as paper. However, this legal recognition is conditional. To qualify under the ETDA, a digital document must be susceptible to Exclusive Control.
The Challenge of Cryptographic Singularity in eBL
A standard PDF or a simple blockchain hash is easily copied. In the physical world, possession of the original paper B/L represents exclusive control of the cargo. In the digital realm, achieving this requires Cryptographic Singularity in eBL—the absolute assurance that only one valid, functional instance of the document exists at any given time, and that its transfer strips the previous holder of their control.
Building the Exclusive Control Infrastructure
Maresign architected its platform specifically to satisfy the rigorous demands of the UK ETDA and UNCITRAL MLETR frameworks.
Immutable Ledger-Vault Architecture
Our infrastructure ensures that an eBL acts as a singular, indivisible asset.
State-Backed Validation
Transfers of control are authenticated using Qualified Electronic Signatures (QES), providing an irrefutable audit trail of possession.
Absolute Deprivation
When an eBL is transferred on the Maresign network, cryptographic mechanisms instantly revoke the sender's access and control, perfectly mimicking the physical handover of a paper document.
For banks financing global trade, Maresign's Exclusive Control Infrastructure transforms digital promises into legally unshakeable statutory assets.
