  • Timeframe & Budgets For Web3 Development

    Timeframe & Budgets For Web3 Development

    In this article I’m going to provide a timeframe, gantt chart and budget costs for web3 development projects. This assumes a medium sized project for something like a new, innovative DeFi protocol consisting of 5-10 interconnected smart contracts and around 1000 lines of code plus an external audit and dApp frontend. If you are just […]

    Aligning Founders, VC’s and Stakeholders Interests In A Smart Contract

    The blockchain sector prides itself on openness and transparency. Except that is when it comes to early stage VC deals and token allocations. In this article we are going to look at an experimental solidity smart contract which lays out terms, vesting schedules and milestone bonuses on-chain. Team Allocations and VC Unlock Schedules This is […]

  • Ownable vs Permissionless Smart Contracts

    Ownable vs Permissionless Smart Contracts

    One of the beautiful things about smart contracts is they can be permissionless where the developers relinquish control to the community and all users are treated equally. However less than 20% of the top 50 protocols by TVL on Ethereum are using fully permissionless contracts. In this article we will look at why this is, […]

  • Zero Knowledge Proof | How ZKP Works In Blockchain Applications

    Zero Knowledge Proof | How ZKP Works In Blockchain Applications

    Zero knowledge proofs offer a method for developers to prove data validity or knowledge of data without revealing the data or additional information about the prover. Zero knowledge proofs are becoming widely used in blockchain applications from smart contracts like Tornado Cash to ZKrollups which are layer 2 blockchains on top of Ethereum. In this […]

  • 3 Examples Of How To Use Assembly In Solidity

    3 Examples Of How To Use Assembly In Solidity

    Ethereum developers can directly use assembly in Solidity to improve the performance of their code. When OpenSea released the Seaport upgrade it reported the use of assembly reduced gas fees by 35% saving it’s users an estimated $460m per year. Today we are going to go through some simple examples of how and when to […]
