Distributed Ledger Governance
Long Blog – Explaining Visa, Canton, and the Architecture of Super Validators
Executive Summary
- Stablecoin Industrialization: DLT is transforming settlement and interbank networks. There is more than one approach, ranging from closed networks to open on-chain. We discuss differences between Ethereum, JPM Kinexys and Canton Network.
- Governance as a Catalyst: Governance and operational oversight have surpassed technical specifications as the primary factors driving institutional participation in distributed ledgers.
- Visa’s “Super Validator” Role: Visa expands their network governance role into Canton as a Super Validator, applying its established “network of networks” model and operational rigor to a privacy-preserving institutional infrastructure. Trust requires a commercial construct and Visa has it.
- Canton’s Privacy Architecture: Unlike public chains, Canton uses a “proof-of-stakeholder” model where transaction data is encrypted and distributed only to parties with a “need-to-know”.
- Super Validators Explained: Visa provides services to manage the “Global Synchronizer,” providing secure sequencing and atomic settlement across domains without ever decrypting sensitive transaction payloads.
- Transition from Silos: The native deployment of JPM Coin onto the Canton Network signals a definitive shift from closed “digital silos” to an interoperable, institutional-grade ecosystem.
- Solving the Interoperability Paradox: The Super Validator model addresses the “SWIFT challenge” by allowing banks to maintain private ledgers while enabling the universal connectivity required for global trade. Yes there will still be closed networks, but Canton is shaping up to be the best universal bank network.
Stablecoin Rewards’ Last Hope – Clarity Act
Summary
- Clarity Act stuck in Senate on Stablecoin Rewards, 70% chance of passage this year
- Stablecoin yield (or anything that resembles it) goes away, and rewards look more like what you have on your Visa card. Coinbase pulled out because of crypto restrictions in the bill (not stablecoin).
- Industry will likely pivot to sweep, and Stableocin becomes just another rail, which will require consumer and merchant adoption, without the big “draw” of balance rewards. Thus, balances stay in transactional and interest-bearing accounts, and friction increases w/ stablecoin payments.
- Politics of key players and quotes in blog today.
The Digital Asset Market Clarity Act of 2025 (H.R. 3633) is the last hope for Stablecoin issuers to save rewards. While the bill passed the House with a strong bipartisan vote on July 17, 2025, its progress has stalled in the Senate (as of Feb 2028) with intense disagreements regarding the regulation of stablecoin “rewards” and yield-like incentives.

Exec Summary (3 pages of bullets below)
The politics and incentives around these device graphs are very complex because they define how risk is managed and controlled. Today, Merchants (and their partners) are the leaders because they own the risk (100% in the US, 50% in the EU). Today’s blog is a recap of the politics and the forces driving perfect authentication, and how this would profoundly impact the politics and the competitive positions of key payment stakeholders.

Bank Payment Strategy in the World of Agentic and Stablecoin
Stripe’s recent moves are massive and will solve stablecoin acceptance (globally). When (and if) a consumer champion goes all in on stablecoin we will see change in payment innovation akin to the “age of enlightenment”. What are banks to do?
Cards are the most profitable banking product in the history of retail banking, and the power of banking is unlocked within the networks that link them (blog). While the power of banking is unlocked in networks, network innovation is like herding cats as each stakeholder works to protect their existing investments and competitive advantage (see Network Innovation).
Real-Time Settlement Coming to US Cards?
US Payment Infrastructure is in the midst of completing a major renovation.
- The Clearing House (TCH) Real-Time Payment (RTP)
- FedNow
- JPM’s ONYX (now renamed Kinexsys)
Let me preempt the #1 question most of you are about to ask “are card volumes at risk”? Nope, why on earth would banks want to walk away from the most profitable retail banking product in the history of man (see Future of Retail Banking)!?
eCom – Politics and Scenarios
Frank Young – Contributor
What are banks talking about this week? How did Apple’s announcement impact them? While 15bps on 2% of eCom GDV is a nuisance, 15bps on 15% of eComm GDV is an earthquake.
Akoya – Short Blog
My #1 favorite new banking service in the US. Well done Akoya, TCH and member banks.

It’s hard to believe I’ve been writing about payment tokenization for 11 yrs. Tokenization is an overloaded term with multiple definitions. Last week McKinsey wrote a fantastic article on crypto tokenization, this note is about the tokenization of card numbers (PAN to DPAN) performed by network tokenization services like Visa Tokenization Service (VTS) and Mastercard Digital Enablement Service (MDES).
This week the US DOJ opened a probe into network tokenization services (Bloomberg). The specifics of the probe are not known
Payments and Identity – UPI continues to lead the world
Short 4 page blog
I’ve written heavily on payments, trust networks and identity. Today I’m providing an example of how UPI, powered by UIDAI’s centralized identity, is creating a new cannon for next-generation payment networks and trust.
I believe that mobile platforms are well placed to learn their lessons in India and create a new phone based network agnostic identity platform that will drive a significant change to payments, the internet and how we manage trust with counterparties.
