NFTs and the Algorand Blockchain

10 Academy, a not-for-profit community-owned initiative that has developed scalable, financially sustainable, and effective training programs to place young Africans into careers for the 4th industrial revolution, wants to give certificates for its trainees in NFTs by partnering with Algorand to use the Algorand blockchain as the foundational element of the NFT. The objective of this project is to build a distributed app that will allow 10 Academy generate and distribute non-fungible tokens (NFTs) as certificates that will represent the successful completion of a weekly challenge to trainees, and allow trainees with NFTs to interact with a smart contract to perform predefined actions.

Project Components and Tools

Algorand is an open-source, decentralized blockchain network that leverages a two-tiered structure and a unique variation of the proof-of-stake (PoS) consensus mechanism to increase transaction speeds and achieve finality. That means processing over 1,000 transactions per second (TPS) and achieving transaction finality in less than five seconds. Algorand has a unique two-tiered blockchain structure. The base layer supports smart contracts, asset creation, and atomic swaps between assets. All of these processes take place on Layer 1 of the Algorand blockchain, which helps ensure security and compatibility. It has an API available for developers to access the Algorand blockchain, which makes it easy to build web3 apps. Some facts on Algorand at the time of writing:

Market cap: 1,993,468,594, which sits at 27th place among cryptocurrencies Total amount of accounts available: 26,084,372 Transaction fee: 0.00029 dollar (really low) Price: 0.2893 dollar for one ALGO Latest block number: 21,697,274

Technologies Used for Web3 Development

Reactjs (Frontend) is a declarative, efficient, and flexible JavaScript library for building reusable UI components. It is an open-source, component-based library that is responsible only for the view layer of the application. Django (Backend) is a high-level Python web framework that encourages rapid development and clean, pragmatic design.

Implementations of the Project

For this project, we used ReactJs to create a user interface for trainees and staff members. The trainees have a page to request certificate and opt-in to the NFT asset. The staff has a page to view certificate requesters and mint NFT for the trainees. We used this tool to connect to the Algorand sandbox and get wallet addresses, create NFTs, handle user authentication and profile and provide the API for each functionality. Some steps involved in the process of requesting and minting NFTs:

Lessons Learned

I have learned a lot of concepts in Web3 and blockchain technology from working on this project:

Blockchain is a decentralized peer-to-peer system with no central authority and using a consensus mechanism to make decisions. Blockchain is built on top of nodes, which are able to create the blocks to be chained. Everything on the blockchain is a transaction. Wallets in a blockchain are made possible (and secure) using security and encryption methods like secure hashing algorithm, private key and public key pair. Most used consensus algorithms include proof-of-work (eg. bitcoin) and proof-of-stake (eg. Algorand). Immutability exists in the blockchain except it differs accordingly because on some of them if you own 51% of nodes then you will be able to alter a transaction.

Some concepts specifically on this project include:

Algorand is a really fast and scalable blockchain platform that uses proof-of-stake protocol to finalize transactions immediately. Algorand enables the minting of NFTs using its Algorand standard assets feature. Before anyone can send you an asset you need to opt-in so that the sender can’t send to you whenever they want without your consensus. The Algorand Sandbox really lets you have fun and learn how to access the blockchain.
