Truffle Migrations Explained

Truffle Migration: A Powerful Tool to Automate the Deployment of Smart Contracts Migrations is a way for developers to automate the deployment of data and its support structure. They are very useful in managing the deployment of new software versions and are not limited to blockchain development. Truffle migration allows us to "push" smart contracts to the Ethereum blockchain (local, testnet or mainnet) and set the necessary steps to connect the contract and populate the initial data of the contract. The real advantage of Truffle migration is managing contract addresses on the blockchain. This usually tedious work is almost completely abstracted through Truffle.

Solidity Pitfalls: Random Number Generation for Ethereum

This article is sponsored by iOlite. Thank you for supporting the partners who made SitePoint possible. Solidity is a relatively new language that contains issues related to the code and its intended use because there is no perfect code. This article will guide you best practices and pitfalls when using random numbers as input to Ethereum smart contracts. Key Points Due to its deterministic nature and the high cost of complex algorithms, the Solidity language itself cannot generate true random numbers. Developers need to be aware that in some cases, an attacker can predict the results. One common way to generate pseudo-random numbers in Solidity is to use the Linear Congruence Generator (LCG) algorithm. However, it does not apply
