Solidity, the programming language for Ethereum smart contracts, offers immense power and flexibility. But with great power comes great responsibility – the responsibility to secure your code and prevent unauthorized access. This is where access restriction patterns come in. Why Access Restriction Matters Imagine a smart contract managing a community treasury. You wouldn’t want anyone […]
In the realm of blockchain development, ensuring the legitimacy of off-chain actions is crucial. This becomes particularly important when integrating functionalities that require user interaction outside the smart contract’s direct control. This blog post dives into a powerful approach that leverages the capabilities of Web3.js. We’ll explore how to sign messages off-chain using Web3.js and […]
Today, let’s delve into the fascinating world of Ethereum smart contracts and explore the critical concepts of gas limits, the associated vulnerability of running out of gas, and effective strategies for mitigation. Gas in Ethereum: Gas is the computational unit that powers the Ethereum network. Every operation on the Ethereum Virtual Machine (EVM) consumes a […]
In the ever-evolving landscape of cybersecurity, Zero-Knowledge Proofs (ZKPs) have emerged as a powerful cryptographic tool that allows one party to prove the authenticity of a statement without revealing any information about the statement itself. This concept might sound like magic, but it’s grounded in advanced mathematics and has profound implications for security and privacy. […]
