Crypto spent years optimizing transactions. Now we're entering an era where interactions matter more than transactions. AI agents interacting with protocols. Applications interacting with external systems. Organizations interacting with autonomous software. The question is no longer: "Can the transaction execute?" The question is: "Can the entire system coordinate safely?" That shift changes how infrastructure needs to be designed. Projects like @RialoHQ are interesting because they seem focused on execution environments built for interaction, not just transaction processing. Feels like a subtle distinction today. Could become a very important one tomorrow.
