ChainGuess is a decentralized number guessing game designed to help beginners learn how to: Build smart contracts using Solidity. Deploy on the Celo blockchain. Interact with on-chain events and ETH-based rewards. The goal is to create a fun, transparent, and educational blockchain mini-game that showcases basic Solidity concepts like state variables, events, and randomness.

Vote choori refers to any illegal activity done to manipulate or steal votes during an election. It is a form of electoral fraud where individuals or groups try to change the election results unfairly. This can happen in many ways—such as casting fake votes, tampering with voting machines, pressuring voters, buying votes, or altering vote counts. Vote choori destroys the fairness of democracy, because leaders are chosen without the true consent of the people. It creates mistrust in the election…

NoteFi is a simple yet powerful decentralised writing platform built using Solidity. It allows users to publish short text-based notes directly on the blockchain — without any central authority or censorship. Each note belongs to its author, can receive ETH tips from other users, and is stored immutably once created. This project is great for Web3 beginners to learn about: - Structs and mappings - Events and modifiers - Ether transfers - Smart contract architecture

Decentralized Notes is a simple smart contract written in Solidity that allows anyone to store, retrieve, and manage their personal notes directly on the blockchain. Instead of relying on centralized servers or apps, this DApp ensures your notes are secure, censorship-resistant, and always accessible through your wallet address. It’s designed as a beginner-friendly blockchain project — perfect for learning how smart contracts work with mappings, events, and state variables in Solidity. GitHub…

The Voting DApp allows users to vote for their favorite candidates in a transparent and verifiable way. Each voter can vote only once, and every vote is recorded on-chain, making it immutable and auditable. 🧩 Designed for beginners learning Solidity and Celo DApp development.

Traditional voting systems often rely on centralized authorities that can be vulnerable to manipulation, corruption, or data loss. Amrita Ki Sarkar solves this problem by using blockchain technology to make elections secure, transparent, and immutable. This smart contract is written in Solidity and deployed on the Celo Sepolia Testnet. It demonstrates how governance and democracy can be reimagined in a decentralized world.
