    Insecure Randomness in Smart Contracts

    Smart contracts on blockchain cannot achieve true randomness due to the deterministic nature of blockchains, pushing developers to use pseudo-random number generators (PRNGs). Methods relying on block properties or blockhashes are susceptible to miner tampering and predictability. External solutions like Chainlink VRF and onchain VRFs like Harmony VRF offer more secure random number generation but come with additional costs. The Signidice algorithm and the commit-reveal approach provide additional methodologies, each with their own sets of advantages and limitations. The choice of method depends on the specific requirements and incentives of the contract.

    How I build my first DApp project (Web3 NFT Marketplace) using Reactjs, Tailwind CSS, and Solidity (Part 2)

    This post continues the guide on building a Web3 NFT Marketplace using Reactjs, Tailwind CSS, and Solidity. It covers steps like updating the store file, creating and importing various components (UpdateNFT, Footer, Alert, Loading), and updating the smart contract with necessary functions. Additionally, it provides backend logic including setting up blockchain services and connecting to a wallet using Web3. The final step involves deploying the smart contract locally and running the DApp.
