## Description

Ed Marquez, Head of Developer Relations at Hedera, leads a technical workshop on building decentralized applications using Hedera’s SDKs, EVM compatibility, and AI agents. He explains Hedera’s technology stack, including consensus nodes, mirror nodes, and native services like the Consensus Service (HCS) and Token Service, which enable developers to create fungible and non-fungible tokens without smart contracts. Ed demonstrates using the Hedera Playground for rapid prototyping, showing how to create accounts, tokens, and perform token airdrops with JavaScript SDK.

He highlights EVM compatibility, allowing Solidity smart contracts and familiar tools like Hardhat and Foundry. The Hedera Agent Kit SDK is introduced for building AI agents that interact with the network, automate tasks, and integrate with frameworks like LangChain. Real-world use cases include Karate Combat (governance tokens), Equity Lab (verifiable compute with Nvidia), Neuron (IoT data logging), and Hyundai/Kia (CO2 monitoring). Ed concludes with details on hackathon bounties for AI, EVM, and cross-chain projects, encouraging developers to engage and innovate on Hedera.
