This established the foundational principle that DLT-based records carry the same legal effect as traditional book-entry systems maintained by central securities depositories. *** **Blockchain Law II — Law of 22 January 2021** The second law extended DLT recognition to a broader range of financial instruments and introduced the concept of the "DLT register" as a legally recognised form of securities registration. It amended the Luxembourg law of 5 August 2005 on financial collateral arrangements, confirming that financial collateral — including pledges over securities — could be validly constituted and enforced over DLT-registered instruments. This was a critical development for structured finance and securitisation, as it confirmed that security packages over tokenized instruments are legally enforceable under Luxembourg law. *** **Blockchain Law III — Law of 15 March 2023** The third law introduced the most significant structural innovation: the concept of the "central account keeper" operating on DLT infrastructure, and the formal recognition of tokenized securities as a distinct but legally equivalent form of traditional securities. It amended multiple Luxembourg financial sector laws to confirm that issuance, transfer, and pledge of securities represented by tokens on a DLT register produce the same legal effects as equivalent operations on traditional centralised registers. This law directly underpins T-Blocks' digital rail architecture, confirming that token transfers executed on the XRP Ledger carry full legal effect under Luxembourg law. *** **Blockchain Law IV — Law of 2024** The fourth law further refined the regulatory framework by aligning Luxembourg's DLT securities legislation with the EU's DLT Pilot Regime (Regulation (EU) 2022/858) and MiCA framework (Regulation (EU) 2023/1114), ensuring coherence between Luxembourg's domestic blockchain law and the evolving EU-level digital asset regulatory architecture. It confirmed the treatment of DLT-based instruments within Luxembourg's existing financial sector supervisory framework, providing additional regulatory certainty for institutional issuers and investors operating within the Luxembourg securitisation and fund ecosystem. *** **Practical significance for T-Blocks** Luxembourg's four-law blockchain framework means that instruments issued through T-Blocks Trio Fund and tokenized on the XRP Ledger or other DLT infrastructure are not operating in a legal grey area. The token representing an investor's interest in a SubFund instrument has the same legal standing under Luxembourg law as a book-entry position held at a traditional central securities depository. Transfer of the token constitutes legal transfer of the instrument. Pledge of the token constitutes valid financial collateral. The on-chain register is a legally recognised register. This legislative foundation is one of the primary reasons Luxembourg was selected as the jurisdiction for T-Blocks securitisation infrastructure, and it distinguishes Luxembourg-domiciled tokenized securities from instruments issued in jurisdictions where the legal status of DLT-based ownership records remains unsettled.
