Diagram showing the three problems of the agentic economy: Identity, Settlement, and Coordination

The agentic economy has twin problems. It actually has triplets.

My feed did it again. Third time in six weeks: something launches in the agentic commerce space, the usual suspects celebrate, and I find myself writing about it. In late December I published an architecture for agentic travel distribution that I’d been designing for months; that one was proactive, and the reactions suggested it resonated. Then Google launched UCP two weeks later, and I wrote about what travel needs from it. Now ERC-8004, the Ethereum standard for “Trustless Agents,” goes live on mainnet, and my timeline is a chorus of people announcing that AI agents finally have identity, reputation, and wallets. (I managed to resist when Coinbase launched x402, so at least there’s that.) ...

UCP: Retail got agentic checkout. Will travel get booking?

Google's UCP changes the agentic commerce conversation. Here's how it could book travel.

A follow-up to “Why your AI travel agent can dream up the perfect trip but can’t book it” I published that article on December 29th. Two weeks later, back at my desk with inbox overflowing, I find that Google has launched the Universal Commerce Protocol, co-developed with Shopify, Walmart, Target, Etsy, and Wayfair, and endorsed by twenty-plus others including Visa, Mastercard, and Stripe (apparently I wasn’t the only one busy during the holidays). Their roadmap explicitly mentions “Travel, Services” as upcoming verticals. ...

A passport and digital wallet at a hotel check-in desk

How many times did they photocopy your ID in 2025?

The travel digital identity gap, and why blockchain bridges it Late September, I’m in Heraklion for our Travel Un’chained conference. Michael Ros from Sleap.io and I are at the resort reception, and they hand us forms (name, ID number, address, all the fields) before taking our ID cards and disappearing to make photocopies. In 2025. Facial recognition at airports, digital wallets on our phones, and a process still requiring a paper scan. I know we both used the anecdote to smile with other attendees, so with this article I officially exhaust its value as storytelling. ...

AI Dreams vs Infrastructure Executes

Why your AI travel agent can dream up the perfect trip but can't book it

And how the infrastructure we’ve been building for 2.5 years might finally make it possible It’s December 2025, and AI agents are everywhere. ChatGPT plans your honeymoon to the Maldives. Claude designs a three-week backpacking itinerary through Japan. Perplexity finds you that off-the-beaten-path trattoria in Bologna. Then comes the moment of truth: “Book it.” And the magic collapses. Your agent stutters. It can’t actually check if that boutique ryokan has availability. It hallucinates a confirmation number. It sends you to Booking.com, which means starting the search all over again. Or worse: a Spanish influencer couple recently missed a flight because ChatGPT incorrectly advised them they didn’t need a visa for Puerto Rico, without mentioning the ESTA. The AI was confidently, dangerously wrong. ...

Travel meets digital euro: Chain4Travel's lessons from the ECB Pioneer Programme

Travel meets digital euro: Chain4Travel's lessons from the ECB Pioneer Programme

Programme context and Chain4Travel’s participation In late 2024, the European Central Bank (ECB) launched an innovation platform seeking “pioneers” and “visionaries” to collaborate on digital euro development. The programme aimed to demonstrate how conditional payments could be implemented technically, provide opportunities for participants to interact with simulated digital euro interfaces, and explore additional use cases for the digital currency. As part of their preparation phase for a potential digital euro launch, the ECB invited stakeholders including merchants, banks, payment service providers, fintech companies, and technical experts to participate in this groundbreaking initiative. ...

In a moment where the focus can’t be only on people’s #travel, airlines are boosting their other focus as the fabric of commerce and logistics. #blockchain fits naturally in this space, and it’s exciting to follow the progress of this initiative less fancy but well positioned to democratize the cargo #aviation.
