    Building a decentralized vault using stateful smart contracts

    Vaults are a security mechanism to prevent cryptocurrency from being immediately withdrawn by forcing its creator to wait a certain wait time after a request has been made, while also giving them the ability to cancel a request that they have not made.

    Reach - The Easiest and Safest way to Build DApps

    Blockchain development is hard. Existing tooling is complex, time-consuming to use and not robust against common programming oversights. Reach is fundamentally changing the way blockchain developers approach their craft, safely, efficiently and with formal proofs.

    Algorand Developer Bootcamp | Beginner

    ### Why should I be interested in learning about Algorand and participating in the Bootcamp? * Algorand has different SDK’s to help you with the building process in different languages and with extensive documentation. * The costs and speed for testing on Algorand are extremely low, which will allow you to learn and test without friction. * The companies that work with Algorand are constantly looking for developers to join their work teams. At the end of the Bootcamp you will be able to participate in solving challenges that will test your knowledge and will serve as a cover letter for you to apply for a Web3 job in the Algorand ecosystem. * This Beginner bootcamp will give you the foundations needed to take part in our Intermediate bootcamp. * Grow your web 3 developer skills on time to be able to participate in our exciting Global Virtual Hackathon at the end of the year. We’ll release more details shortly. **Each session will be 2 hours. Here’s what you can expect to cover over the 4 days:** * Session 1: Algorand Developer Onboarding with JavaScript SDK & AlgoKit Installation * Session 2: Building a dApp with Beaker and Deploying with dAppFlow * Session 3: Building & Debugging dApps with Beaker + PyTeal + PyTest * Session 4: Adding a TypeScript Frontend UI to the Auction dApp ### Why Algorand? When you decide to start working in blockchain, it is essential that you know the characteristics of the protocol that you are going to use, here are those of Algorand: * It is a layer 1 network that can process 10,000 transactions per second. * The cost per transaction is 0.001 ALGO == $0.0003 USD Approx. * Our blocks are processed in 3.3 seconds. * We are a carbon negative blockchain as we are committed to being environmentally friendly.

    Intro Bootcamp

    ![EditorImages/2024/03/15 15:02/1918x548.png](https://algorand-devloper-portal-app.s3.amazonaws.com/static/EditorImages/2024/03/15%2015%3A02/1918x548.png) **Project:** Asset creation and transaction using AlgoKit SDK. **Bootcamp Description:** One of Algorand's main features is the possibility of creating accounts and assets, and sending transactions, without a smart contract. That's why we’ve created this bootcamp: to help you take your first steps into Algorand development using the AlgoKit SDK. **Time: 10:00 AM EST** **Duration:** 90 mins each session **Agenda:** * Session 1 (April 2nd): Introduction to Algorand concepts and AlgoKit SDK. * Session 2 (April 4th): Using AlgoKit and dev environment Setup. **Prerequisites: ** * GitHub Account - [Sign up ](https://github.com/signup) * [VS Code](https://code.visualstudio.com/) (Recommended) **Why Algorand?** Algorand is an enterprise-grade programmable layer-1 blockchain – the perfect place to start (or continue) your blockchain journey. * Blocks on Algorand are processed in under 3 seconds. * The Algorand network can process more than 10,000 transactions per second, all with instant finality. * The cost per transaction is 0.001 Algo (just a fraction of a cent). * Algorand is carbon-neutral and built environmentally friendly from the ground up. * Testing on Algorand is fast and cost-efficient, allowing you to innovate without friction. * Plus, it has a wealth of developer tooling, tutorials, and documentation. Ready for the best bit? If you’re a Python or TypeScript dev, you don’t need to learn a new language because you can build on Algorand in Python and TypeScript. It’s easy to get building thanks to [AlgoKit](https://developer.algorand.org/algokit/?utm_source=devportal&utm_medium=bootcamp_landingpage&utm_campaign=algokit) (our solution to speed up your Web3 building process).
