Anthony Soohoo is 18 months into transforming MoneyGram - 500,000 locations, 200+ countries - into a developer-led payments network running on blockchain and stablecoins. The catch: customers never see the tech. They just hold a dollar-backed balance in the app while AI orchestrates treasury, FX, and settlement on the back end.

In this episode, Anthony breaks down the three pillars of MoneyGram 3.0, why he chose open interoperable rails over building proprietary ones, how his team brought regulators along across dozens of jurisdictions, and why he believes payments is about to hit its "iPhone moment" - where AI, embedded finance, and digital assets converge all at once. If you're at a legacy financial institution weighing whether to build on open infrastructure or keep your rails closed, this is the conversation to listen to.

Issuing a stablecoin used to require a nine-figure investment, years of regulatory work, and deep banking relationships. For most companies, that barrier made participation impossible.

In this episode of block by block, Denelle Dixon speaks with Ben Milne, founder and CEO of Brale, about why stablecoin issuance was historically so expensive - and how Brale approached the problem differently. Ben explains how existing regulation made another path possible, why licensing and compliance are central to trust, and how absorbing those fixed costs upfront reduces the marginal cost of issuing a stablecoin to nearly zero.

The conversation covers the economics of stablecoin infrastructure, Brale’s decision to support third-party issuers, and what changes when access to regulated financial rails is no longer limited to the largest institutions.

This Block by Block episode features AirTM CEO Ruben Galindo on the economics of global payroll. AirTM has processed more than $1B in stablecoin payments, paid 250,000 workers in 150+ countries, and reports 20–25% cost savings on cross-border payouts. Galindo explains how stablecoin payments are converted to local currency in minutes, why the “last mile” is the real challenge in international payroll, and what reliable settlement means for enterprises looking beyond traditional payment processors.

In this episode of block by block with Denelle Dixon, Austin Campbell (Founder of Zero Knowledge Consulting, NYU Stern professor, former Paxos, JP Morgan, Citi) talks through the parts of the financial system most people never see — settlement, velocity, trapped capital, and the tradeoffs between openness, privacy, and control.

Drawing from experience in traditional finance and crypto infrastructure, Austin explains why most tokenization efforts fail, what blockchains actually make possible, and why copying legacy systems onchain won’t lead to greater adoption.

In this episode of Block by Block, Denelle Dixon sits down with Brian Pellegrino, CEO and Co-Founder of LayerZero Labs, to explore how blockchain interoperability is evolving beyond traditional bridges and wrapped assets toward true omnichain infrastructure.
