CCIP — Chainlink Cross-Chain Interoperability Protocol
Chainlink's Cross-Chain Interoperability Protocol (CCIP) enables secure transfer of tokenized assets and messages across different blockchains — adopted by Swift for interbank tokenized settlement tests and by the Australian Stock Exchange for cross-chain digital bond issuance.
Delivery vs Payment (DvP)
Delivery versus Payment is the fundamental settlement principle that transfer of a security must occur simultaneously with payment — eliminating principal risk — and blockchain-based atomic settlement represents the most complete technical implementation of DvP yet achieved.
DTCC — Depository Trust & Clearing Corporation
The DTCC processes over $3 quadrillion in securities transactions annually as the US financial market's central post-trade infrastructure — and its blockchain initiatives (Project Ion, Project Whitney) will determine whether tokenization integrates with or displaces traditional settlement.
DTCC Project Ion and Blockchain Settlement
Project Ion is DTCC's distributed ledger technology platform for accelerated equity settlement, running in parallel with existing settlement systems and processing $1B+ per day in test transactions — the most consequential blockchain initiative for US equity market infrastructure.
