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. Key Points Truffle Migration for Automation of Smart Contracts

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

How to Build Push Notifications for Web Applications
Improve user participation in web application: Detailed explanation of web push notifications This article will explore how to improve the user experience of existing web applications by adding notification functions similar to native applications. We will explain in-depth the concept of web push notifications and gradually demonstrate how to integrate this feature in existing web applications, covering the current specification and browser support. The article was originally published in Sencha. Thanks to the partners who support SitePoint. Core points: Understanding the basics: Web push notifications allow web applications to send messages directly to user devices, even if the application is inactive. Service worker registration: Service worker is responsible for processing push messages, must register when the page is loaded and browse appropriately

Building Ethereum DApps: Voting with Custom Tokens
Core points Use custom tokens in DAO for proposal voting, including deleting entries and blacklisting addresses, thereby enhancing decentralized governance and operational flexibility. Implement a powerful voting mechanism that requires verification of token ownership and locking tokens during the voting to prevent manipulation and ensure commitment. Design proposal and voting systems with structured deadlines and implementation standards to maintain orderly and efficient DAO operations. Address potential security issues by limiting proposal creation to member-only and enabling emergency deletion features controlled by DAO owners. Explore the technical challenges and solutions for deploying large smart contracts on Ethereum, emphasizing the importance of code optimization to manage gas costs and ensure successful deployment. The tutorial series

Debugging with Truffle CLI
Solidity Smart Contract Debugging: Truffle CLI Practical Guide For more than 30 years, debuggers have been an indispensable tool in software development. Modern debuggers enable us to: Step-by-step code Set breakpoint Set conditions for breakpoints Runtime evaluation expressions Most modern debuggers are highly integrated into the development environment of the languages they serve. They allow setting breakpoints by clicking on line numbers, evaluating expressions by hovering over variables, writing conditional breakpoints in code comments... and so on. So, what is the current situation of Solidity smart contract debugging and debugger? Key Points Truffle CLI is an integral part of the Truffle suite, it provides

How Memory & Disk Performance Affects Your MongoDB Database
This article was originally published in MongoDB. Thanks to the partners who support SitePoint as a possible one. Understanding the relationships between various internal caches and disk performance and how these relationships affect database and application performance can be challenging. We used YCSB benchmarks to change the working set (the number of documents used in the test) and disk performance to better demonstrate their relationship. When reviewing the results, we will introduce some MongoDB internal mechanisms to improve understanding of common database usage patterns. Key Points Understanding disk baseline performance is critical to understanding overall database performance. High disk waiting time and utilization indicate a disk bottleneck. WiredTiger IO is with
