Web3

Web3 refers to a vision for a decentralized internet built on blockchain technology, enabling peer-to-peer interactions without central authorities. It encompasses decentralized applications (dApps), cryptocurrencies, smart contracts, and token-based economies, aiming to give users control over their data and digital assets. This paradigm shift contrasts with the centralized models of Web 2.0, where platforms like social media and e-commerce sites act as intermediaries.

Also known as: Web 3.0, Web3.0, Decentralized Web, Blockchain Web, Semantic Web (historical context)

🧊Why learn Web3?

Developers should learn Web3 to build applications in emerging fields like decentralized finance (DeFi), non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs), where trustless and transparent systems are essential. It's particularly valuable for creating solutions that require censorship resistance, data ownership, or automated agreements without third parties, such as in supply chain tracking or digital identity management.

Other Blockchain

Access Control is a fundamental security concept that governs how users, systems, or processes are granted or denied access to resources such as data, applications, or networks. It involves defining and enforcing policies to ensure that only authorized entities can perform specific actions, protecting against unauthorized use, modification, or disclosure. This is implemented through mechanisms like authentication, authorization, and auditing to maintain confidentiality, integrity, and availability in computing environments.

Access tokens are short-lived credentials used in authentication and authorization systems to grant secure access to protected resources, such as APIs or user data. They are typically issued by an authorization server after a user or application successfully authenticates, and they contain claims about the requester's identity and permissions. Tokens are commonly implemented using standards like OAuth 2.0 and OpenID Connect to enable stateless, scalable security in modern applications.

Ad-Based Monetization

Ad-based monetization is a revenue model where businesses generate income by displaying advertisements to users, typically in digital products like websites, mobile apps, or games. It involves integrating ad networks or platforms to serve ads, with revenue earned through models such as cost-per-click (CPC), cost-per-mille (CPM), or cost-per-action (CPA). This approach is common in free-to-use services, allowing developers to monetize user traffic without direct payments from end-users.

AI agents are autonomous systems that perceive their environment, make decisions, and take actions to achieve specific goals using artificial intelligence techniques. They combine machine learning, reasoning, and sometimes natural language processing to operate independently or semi-independently in dynamic environments. This concept is foundational in fields like robotics, game AI, and automated systems.

AI Integration refers to the process of incorporating artificial intelligence capabilities, such as machine learning models, natural language processing, or computer vision, into existing software systems, applications, or workflows. It involves connecting AI services, APIs, or custom models to enhance functionality, automate tasks, or provide intelligent insights. This enables systems to perform tasks like predictive analytics, automated decision-making, or personalized user experiences without building AI from scratch.

AI Safety is a multidisciplinary field focused on ensuring that artificial intelligence systems are developed and deployed in ways that are safe, reliable, and aligned with human values and intentions. It addresses risks such as unintended harmful behaviors, security vulnerabilities, and ethical concerns in AI systems, particularly as they become more advanced and autonomous. The goal is to prevent catastrophic outcomes and promote beneficial AI that serves humanity's interests.
