ECB, BOJ, and Project Stella: rebuilding the cross-border payment rail

ECB, BOJ, and Project Stella sit at the center of how cross-border payments settle. Every part of it traces back to a named, primary source.

The Rail Behind The Headline

This material connects the ecosystem to payment rails and cross-border transaction flows. Supporting material comes from the BOJ Project Stella overview and the ECB/BOJ phase 1 PDF. ECB/BOJ Project Stella phase 3 PDF, a research document from the organizations involved, states it directly:

> 1 Background A Distributed Ledger Technology (DLT) is a set of tools for recording data, such as asset holdings or financial transactions, allowing a network of computers to verify and store updates without a single central management system. In December 2016, the Bank of Japan (BOJ) and the European Central Bank (ECB) announced the launch of a joint research project entitled “Stella” to assess the applicability of DLT solutions in the area of financial market infrastructures.

What This Means For Market Infrastructure

What it changes for the broader institutional payments and tokenization stack: payments infrastructure is a repeat-use case that can create ongoing demand for reliable networks and settlement assets.

One caveat for honest use: Do not claim production deployment.
