Since the Bitcoin whitepaper was first published in 2009, cryptocurrency systems have offered a new decentralized paradigm for digital money. Blockchains such as Ethereum have expanded on that paradigm by enabling smart contracts, software that runs on a blockchain and allows you to create and transfer digital goods. This new paradigm is called Web3, and whereas Web 2.0 software relies on large centralized companies, Web3 software runs on decentralized protocols that let users own and profit from their own data.

In the last 4 years the Web3 ecosystem has seen exponential growth and the introduction of new concepts in software, such as DeFi (decentralized finance) an alternative system for Internet finance, and NFT's (non-fungible tokens) for representing and trading digital art. This smart contract software requires a new set of software design principles that focus on security and composability. The demand for developers who understand the tools and mindset necessary for writing robust smart contracts is real and quickly growing. Yet we are only at the beginning of the shift to Web3. Fundamental improvements to the systems that underlie the Web3 ecosystem are now moving from research into implementation, and it is an exciting time to enter the space.

Our Web3 curriculum is developed in collaboration with industry leaders

Graduates of BloomTech’s Web3 Development program will leave with the skills and tooling experience necessary to build production decentralized apps (dApps). You will learn the best practices for writing and testing smart contracts in Solidity, an extremely popular smart  contract programming language. You will learn how to protect your contacts from devastating vulnerabilities that have caused millions of dollars to be lost from attacks. The program will go into depth on the current trends in Web3 development, such as NFT's and DeFi. And you will learn how to build a frontend app using React that lets you interact with your smart contracts in an intuitive and efficient manner.

The course will cover deployment to both Polygon and Ethereum mainnet. All learners will be provided MATIC to deploy to Polygon but if you’d like to deploy to Ethereum you’ll need to purchase your own Ether. Deploying to mainnet is not a requirement for successful completion of the course.

We are currently not enrolling in the following states: California, Texas, and Georgia, nor in Washington, DC. We are hopeful to open admissions in these states by late Q1.

Frequently asked questions

What is the course format?
All content delivery will be via video accessed via our LMS. Twice a week there will be scheduled Zoom office hours for additional support as well as impromptu sessions. Our instructor will be available via Slack as well for quick answers.
Can I take the course at my own pace?
Yes! While we have cohorted start dates you may advance through the coursework as quickly or slowly as you like. As a reminder you’ll retain course access for 1 full year after enrolling.
What experience or knowledge do I need for this course?
  • 1 - 2 years of experience writing production software in Javascript or its syntactical supersets like TypeScript are critical for success in this program.
  • We will be utilizing bash scripting for various commands throughout this course and a working knowledge of any shell scripting language is required to be successful in this program.
  • Git and a working knowledge of version control systems, like GitHub, are required to be successful in this program.
This course is designed for people who have previous programming experience. We didn’t include a “years of experience” as a requirement but if you have been working with the above daily for at least 1-2 years you are qualified to take this course.
What equipment and supplies do I need for this course?
  • A laptop or desktop computer with the minimum specifications: 1.6 GHz Processor, 4 GB RAM, 120 GB Hard Drive, Web Cam, & Microphone
  • A reliable, high speed internet connection
  • OPTIONAL: Ability to purchase 0.1 ETH for deploying to Ethereum mainnet (apprx. ~$360 USD).
