Web3 is defined as a multi-layer architecture that leverages decentralized protocols and distributed technologies to provide a trusted application framework. At the core of this stack is a decentralized ledger system that enables consensus-based, tamper-proof data management. This architecture integrates several core components: programmable smart contracts that automate deterministic logic, NFTs for representing unique digital assets, decentralized storage mechanisms like IPFS for resilient data distribution, blockchain-based oracles for secure external data provisioning, and crypto wallets for user controlled identity and asset management. This composable technology stack is designed to support powerful, permissionless applications that operate independently of central authorities.
The project addresses the limitations of distributing certificates as static PDF files. The aim is to deliver certificates as digital assets (NFTs) on the Algorand blockchain, supporting on-chain verification, security, and additional functionality through smart contracts.
Algorand offers a Docker-based sandbox for node setup and rapid development.
git clone https://github.com/algorand/sandbox.git
cd sandbox
./sandbox up testnet
./sandbox up testnet -vThe Algorand Python SDK is available via pip.
pip3 install py-algorand-sdkInstructions for account creation are provided at the official Algorand developer documentation.
The sample implementation utilizes a React frontend available from an open-source repository:
git clone https://github.com/BirhanuGebisa/Algorand-dapps_smart-contract.git
cd algorand-NFTs-smartContracts
npm startAccess the local deployment at http://localhost:8080.
npm testinitiates the interactive test runner.npm run buildoptimizes the React application for production output.
Use Flask to run the backend logic:
