AI Agents and Applications

AI Agents and Applications demystifies the most complex techniques of building LLM-based applications, including deploying open-source LLMs locally and fine-tuning them for specific applications. You’ll start from the ground up: LLM architecture, how to adapt them to your needs, and the advanced prompt engineering techniques you’ll need to succeed. From there, you’ll quickly move on to developing effective LLM-powered projects—from a simple tool to summarize documents, to a research assistant that can reliably use the web, a semantic search chatbot, and implementing advanced Retrieval Augmented Generation.

Exploring Ethereum Dapps

In most applications data is collected, stored, and controlled by some central authority such as a bank, retailer, or governmental institution. Decentralized applications, or Dapps, shift control to their users, operating without any single agency managing the process. Instead Dapps store their data in a secure, unchangeable form called a blockchain, maintained concurrently on thousands of servers owned by different parties. Users do not need to trust any institution to be confident their data will be processed and stored correctly; the Dapp technology itself guarantees it. The open-source Ethereum blockchain platform provides tools for developers to start building and deploying their own Dapps, including an innovative smart contracts transaction model and Solidity, a JavaScript-like programming language.

Exploring Ethereum Dapps is a free primer created with hand-picked chapters from Building Ethereum Dapps by Roberto Infante. It explains how decentralized applications work and gets you ready to start building them. You’ll quickly learn with what Dapps look like, how they function, and what kind of application is best suited to being decentralized. Once you’ve grasped the basics you’ll dive into the Ethereum blockchain, including the Ethereum smart contracts that form the basis of all Ethereum Dapps. When you’re done, you’ll have the grounding you’ll need to start building your first Dapps.

Building Ethereum Dapps

Building Ethereum Dapps teaches Dapps development on the Ethereum blockchain platform. You’ll begin with a mental model of how Dapps operate, and then dive into designing and implementing smart contracts in Ethereum’s Solidity language. You’ll explore Ethereum smart contract development tools, like Truffle and Web3, and pick up best practices for design and security. Practical exercises throughout give you valuable hands-on experience.
