Blockhash: Exploring The Blockchain

For episode 625 of the BlockHash Podcast, host Brandon Zemp is joined by Rodrigo Coelho, CEO of Edge & Node. Autonomous agents across blockchain ecosystems are beginning to transact, communicate, and collaborate independently, yet there is no standardized way to manage agent to agent interactions (payments).Edge & Node, the founding team behind The Graph, is solving this problem by providing the missing management layer, Ampersend. Ampersend extends Coinbase’s x402 payment protocol and Google’s A2A communication standard with observability, automation, and compliance-ready controls.The result is an operational system where developers, startups, and enterprises can see how agents interact, set policies, manage budgets, and ensure reliability. Ampersend also aligns with Ethereum’s emerging ERC-8004 agent discovery standard. ⏳ Timestamps: (0:00) Introduction(1:15) Who is Rodrigo Coelho?(8:57) What is Edge & Node?(10:10) What is Ampersend?(12:35) What will the Agentic economy look like?(18:53) Scaling
