This is my solution to Speed Run Ethereum's A State Channel Application Challenge.

Challenge 0 of the Speed Run Ethereum (Griffith)

Challenge 1 of the Speed Run Ethereum

Staking App built with scaffold-eth

Testing the creation of a contract that attacks a dice game. Its easy for the attacker to predict the next dice roll because of how randomness is used in the dice game contract. The contract uses a hashing of the previous block hash, the contract address, and the nonce.

Challenge for Speed Run Ethereum / Decentralized Staking App

Nestcoin needed their own currency and a way to disburse that currency to a large number of loyal customers at most 200 customers per batch. Our team took up the challenge and built a solution, this is the completed version from a previous repo at : https://github.com/Epic-Byte/Nestcoin-Manager

Scaffold-Eth 🏗 Challenges repository

A decentralized application where users can coordinate a group funding effort. If the users cooperate, the money is collected in a second smart contract. If they defect, the worst that can happen is everyone gets their money back. The users only have to trust the code.

🦸 A superpower of Ethereum is allowing you, the builder, to create a simple set of rules that an adversarial group of players can use to work together. In this challenge, you create a decentralized application where users can coordinate a group funding effort. The users only have to trust the code.
