This research article presents a novel architecture to empower multi-agent economies by addressing two critical limitations of the emerging Agent2Agent (A2A) communication protocol: decentralized agent discoverability and agent-to-agent micropayments. By integrating distributed ledger technology (DLT), this architecture enables tamper-proof, on-chain publishing of AgentCards as smart contracts, providing secure and verifiable agent identities. The architecture further extends A2A with the x402 open standard, facilitating blockchain-agnostic, HTTP-based micropayments via the HTTP 402 status code. This enables autonomous agents to seamlessly discover, authenticate, and compensate each other across organizational boundaries. This work further presents a comprehensive technical implementation and evaluation, demonstrating the feasibility of DLT-based agent discovery and micropayments. The proposed approach lays the groundwork for secure, scalable, and economically viable multi-agent ecosystems, advancing the field of agentic AI toward trusted, autonomous economic interactions.

Many of us who have uploaded images of our faces and the faces of our friends and family to openly-licensed platforms on the Web may have inadvertently contributed to a massive and growing database for AI facial recognition. So how are our faces being used? So have we all thrown away our privacy and assumption of innocence for a selfie? The film is Web Monetized, with all streaming payments going to the Surveillance Technology Oversight Project (S.T.O.P.) On the GftW Community Forum, we have been streaming funds to S.T.O.P. since July. So far, we have generated almost $200 in micropayments to support their work.

What if the next life were no better than this one? Not a heaven or a hell, or even a purgatorial waiting room, but a world that operates according to the same rules as the one that came before it, only tweaked enough that we don't just accept them as the way things have to be. In the near future of Upload, whose first season begins streaming on Amazon Prime on Friday, death is not the end, at least for those with the resources to survive it. But the hereafter in Greg Daniels' series isn't spiritual, it's digital, and everything, including entry and your continued existence, comes at a cost. It's less like heaven than a cruise ship on an infinite voyage, one where everything is marked up because the dead aren't in much of a position to comparison-shop. Nathan Brown (Robbie Amell) finds his way to Lakeview, as his particularly plush digital forever is called, after his self-driving car rear-ends a garbage truck.

With the new year approaching and a new decade on the horizon (yes, technically it starts in 2021), we wanted to look at transformations in media that are likely to define the 2020s. Especially in the media and computing fields, the decade proves to be a useful marker. Consider that at the end of 2009, Digital Cinema and 3D film was just being introduced with the release of Avatar, GPU rendering was in its infancy, YouTube was less than 1/20th the size it is today, and Netflix video streaming had yet to be launched internationally. Meanwhile, cloud computing had just started its adoption curve, the first augmented reality print campaign was launched, and blockchain mining was in its first year. It's fair to expect that when we look back a decade later, the end of 2019 will similarly look distant - if not more remote with the accelerating rate of change in media and technology.
