McDermott confirms Goldman Sachs is building its "Digital Asset Platform" on the Canton Network. He explicitly mentions Broadridge (BR) as an extensive user for collateral mobility and repo operations. Institutional adoption isn't happening on public Ethereum mainnet due to privacy requirements.

Goldman and Broadridge are the first movers building the actual "plumbing" for institutional blockchain (collateral mobility, repo), positioning them to reduce back-office costs and increase liquidity efficiency. LONG. These are the infrastructure winners in the "Permissioned/Institutional" blockchain thesis. Adoption of permissioned chains stalls in favor of public chains (L2s); regulatory reversal.
