Today I'm going to show you how I deployed a simple NFT contract to Soroban, Stellar's smart contract platform. Whether you're an artist, a developer, or just curious about blockchain, this tutorial will guide you through the process step-by-step. Let’s get started. You'll need a few things to ge| JamesBachini.com
In this tutorial, we'll explore how data is stored on Stellar's Soroban smart contract platform, focusing on Soroban's state management and the types of storage available. Understanding these concepts will allow you to manage data optimally and keep your decentralized applications efficient.| JamesBachini.com
Blockchain storage is limited and block space is therefore expensive, especially at times of peak congestion. Solidity developers must employ strategies to optimise data storage whilst maintaining the integrity and accessibility of their smart contracts. One of the most effective approaches is to| JamesBachini.com
Among Solidity's essential features are the fallback and receive functions, which play crucial roles in handling Ether transactions and contract interactions. A thorough understanding of these functions is vital for developers aiming to create robust and secure smart contracts. The Fallback Funct| JamesBachini.com
The Inevitable Loss Facing Early Cryptocurrency Hodlers Substantial amounts of digital assets are going to be lost forever over the next few decades. The first generation of crypto hodlers will be dying off and many of their holdings will die with them. These losses, often caused by misplaced| JamesBachini.com
