How to Choose a VPS: Shared Hosting vs. Dedicated Virtual Servers

Mon, 07 Jul 2025 09:00:00 +0900

Choosing the right VPS (Virtual Private Server) is essential for developers and website operators. This guide explains the key factors to consider when selecting a plan and provider.

What is Web3? How Blockchain Reinvents the Web Ecosystem

Thu, 31 Oct 2024 09:00:00 +0900

Hello! Today we will explain the concept of Web3 in an easy-to-understand way, exploring how blockchain technology is reinventing the internet ecosystem.

Evolution of the Web

Web 1.0: The era of read-only static websites where users consumed content published by a small number of creators. This phase lasted from the early 1990s through the early 2000s.
Web 2.0: The era of read-write interactive platforms dominated by tech giants. Social media, user-generated content, and centralized platforms transformed how we communicate, but also concentrated data ownership and monetization in the hands of a few corporations.
Web3: The read-write-own era powered by blockchain decentralization. Users reclaim ownership of their data, digital assets, and online identities through decentralized protocols and cryptographic verification.

Core Features of Web3

Decentralization: Direct peer-to-peer (P2P) transactions and interactions without requiring intermediaries like banks, platforms, or marketplaces. Smart contracts automate trust and enforcement.
Self-Sovereign Identity: Users control their own digital identities and personal data through cryptographic keys, choosing what information to share and with whom—rather than surrendering data to centralized platforms.
Token-Based Economics: Native digital assets (cryptocurrencies, NFTs, and governance tokens) enable new economic models where users can be compensated for their contributions to networks, creating aligned incentives between platform operators and participants.
Smart Contracts: Self-executing contracts with terms directly written into code, enabling automated, transparent, and trustless agreements across countless applications.

Real-World Applications

Web3 is finding practical applications beyond cryptocurrency speculation. Decentralized finance (DeFi) protocols offer lending, borrowing, and trading without traditional banks. Non-fungible tokens (NFTs) enable digital art ownership and new models for content monetization. Decentralized autonomous organizations (DAOs) allow communities to collectively manage treasuries and make decisions through token-based voting.
