Common Security Ledger

Definition ∞ A Common Security Ledger refers to a shared, immutable record-keeping system used to track ownership and transfers of digital assets or securities. This ledger is maintained across a distributed network, providing transparency and cryptographic integrity for all recorded transactions. It underpins many blockchain-based financial systems.
Context ∞ The concept of a Common Security Ledger is central to discussions on modernizing financial market infrastructure, particularly for tokenized securities and digital bonds. Its implementation aims to streamline post-trade processes, reduce reconciliation efforts, and enhance the overall efficiency and security of asset management in capital markets.
