From T+2 clearing to atomic DVP on a distributed ledger — and from ECDSA to ML-DSA before the quantum computer arrives. One integrated framework for the practitioners who build and govern financial market infrastructure.
Settlement is broken, not just slow. The architecture beneath the world's markets was designed in the 1970s on paper-based conventions — and every day it holds trillions in counterparty risk that simply doesn't need to exist.
6.1% of European equity trades fail to settle on time. Financial institutions spend over $40 billion a year on reconciliation alone — a cost that produces no economic value.
And a second clock is ticking: the cryptography protecting every settlement instruction will be broken by a sufficiently powerful quantum computer. That computer doesn't exist yet. The risk window already includes today.
From T+2 to atomic DVP: the architecture, economics and regulation of distributed-ledger settlement — with production data from Broadridge, SDX, JPMorgan Onyx, the ECB and the EIB, and working Python & Solidity.
Every signature, every channel, at risk. The NIST standards (FIPS 203–205), lattice cryptography for practitioners, and a seven-layer quantum-safe reference architecture — with production Python for every core operation.
The systems studied in the series are live, regulated, and processing real assets at scale — right now.
$1.5T+ settled — the largest deployed blockchain application in financial settlement by volume.
$700B+ processed in 2023 for intraday repo and same-day collateral transfers.
The world's first regulated blockchain CSD (FINMA, 2021) — tokenized bonds settled in real time.
$200B+ processed in DTCC's DLT settlement pilot, now evolving toward T+0 for tokenized instruments.
€1.59B settled across 40 operations with 60+ institutions — Europe's first large-scale wholesale CBDC test.
€400M issued on public blockchains; the first bond settled in under one hour versus five days.
