Atomic Settlement
Atomic settlement is the simultaneous, instantaneous exchange of a digital asset and its payment in a single blockchain transaction — eliminating the settlement risk inherent in traditional financial markets where security delivery and payment occur at different times.
Blockchain Finality (for Tokenized Assets)
Blockchain finality is the point at which a transaction is irreversible — critical for tokenized asset settlement, where probabilistic finality creates settlement uncertainty, and instant finality (Avalanche, Stellar, Solana) solves this for institutional markets.
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.
