Why wallets matter for the agentic economy In a traditional digital transaction, a human enters a credit card number or clicks ‘Pay Now.’ In an agentic economy, an AI agent needs to initiate, sign, and settle transactions autonomously — often across multiple blockchains and payment rails. The digital wallet becomes the agent’s identity and authorization…
Learn what delegation is in AI agents, how it works through privilege attenuation, common patterns like orchestrator-workers, and why multi-hop delegation is a key unsolved challenge in agent security.
You are standing in your kitchen on a Tuesday morning, coffee in hand, trying to get your smart home to cooperate. You tell your phone to dim the lights, lock the front door, and check the weather. Right now, that usually means talking to Google Assistant. It is a familiar, if occasionally frustrating, dance. But…
There was no press release, no celebratory X thread, and no keynote presentation. The transition was visible only through a quiet update to the API documentation at api-docs.deepseek.com, which now lists V4 Pro and V4 Flash as the primary models. On July 17, 2026, DeepSeek V4 moved from preview to general availability. By choosing to…
Data poisoning is a deliberate attack that corrupts AI training data to introduce backdoors, biases, or vulnerabilities. Learn how it works and how to defend against it.
What is the Machine Payments Protocol (MPP)? The Machine Payments Protocol (MPP) is a payment infrastructure protocol developed by Stripe and Tempo that enables AI agents and automated systems to execute payments programmatically across multiple payment rails. Launched on March 18, 2026, MPP provides a unified interface for agent-driven commerce, allowing AI systems to initiate,…
Defining the Agentic Economy Imagine you are planning a complex business trip. Today, you might use a chatbot to find flight options, but you still have to manually book the tickets, reserve the hotel, and update your calendar. In the emerging agentic economy, you don’t do the booking. Instead, you delegate the entire workflow to…
Reinforcement learning teaches AI to align with human preferences through rewards and penalties. Learn how RLHF, DPO, GRPO, and RLVR work, why reward hacking matters, and how these techniques power the agentic economy.
What is a blockchain? A blockchain is a database maintained by a network of independent computers — called nodes — that agree on every update through a shared protocol, rather than relying on a single central authority [1]. Data is stored in blocks that are cryptographically linked to each other in sequence, making the history…
Prompt engineering is the practice of designing and refining the instructions, context, and examples given to a large language model to produce accurate, relevant, and useful outputs—bridging human intent and model behavior through structured communication.
