Blockchain is a distributed ledger technology that uses cryptography to store data securely and immutably across a network of computers. It is a digital ledger of records, called blocks, which are linked together using cryptographic principles. Each block contains a timestamp and a link to the previous block, forming an immutable chain. This makes it virtually impossible to tamper with the data stored in the blockchain, as any changes would be easily detected by the network. In the context of JavaScript, blockchain can be used to create distributed applications (dApps) which are secure, transparent, and decentralized.

Build Blockchain dApps using JavaScript
Have we found nirvana for Blockchain developers? This session will focus on building blockchain dApps (distributed Apps) with one set of source code and deploy to multiple blockchains! The session will cover getting started with Reach and being able to deploy the same solution to multiple blockchains including Algorand, Ethereum, and Conflux. New to Reach? We will cover how to set up your development environment as well as walk through a simple app frontend and backend. Finally, we will look one the huge benefits of Reach in the built-in verification process. Reach provides automatic verifications to ensure that your program does not lose, lock away, or overspend funds and guarantees that your applications are free from this entire category of errors.

Building GraphQL APIs on Ethereum
Blockchains are databases with a unique set of properties. Unlike most databases which are optimized for both read and write operations, blockchains are optimized for write operations, typically focused on optimizing and scaling transaction cost, transaction volume, and transaction speed.
In this talk, I'll dive into the web3 space, and show how developers can leverage The Graph Protocol to build performant, scalable, and decentralized GraphQL APIs and dapps on decentralized networks like Ethereum and IPS.

Building Dapps with React
Decentralized apps (dApps) are continuing to gain momentum in the industry. These developers are also now some of the highest paid in the entire trade. Building decentralized apps is a paradigm shift that requires a different way of thinking than apps built with traditional centralized infrastructure, tooling, and services – taking into consideration things like game theory, decentralized serverless infrastructure, and cryptoeconomics. As a React developer, I initially had a hard time understanding this entirely new (to me) ecosystem, how everything fit together, and the mental model needed to understand and be a productive full stack developer in this space (and why I would consider it in the first place). In this talk, I'll give a comprehensive overview of the space, how you can get started building these types of applications, and the entire tech stack broken apart then put back together to show how everything works.

React on the Blockchain - the Missing Getting Started Guide
Blockchain is arguably a future technology that can be somewhat confusing to get started. Even though there are plenty of resources scattered across the web, but to get started developing distributed apps in React on the blockchain can sound intimidating. In this talk, Vladimir Novick will share how we can get started and what you should know about blockchain architecture. If you always wanted to get into Blockchain development and didn't know where to start, this talk is for you.
