Lightweight APIs: REST, GraphQL, and Beyond APIs let apps talk to each other. When a design stays lightweight, teams move faster and users feel the difference in performance. This post compares REST, GraphQL, and a few practical alternatives, with tips to choose what fits your project. REST remains the everyday choice. It works with resources, HTTP verbs, and standard status codes. It plays well with caching, simple tooling, and clear documentation. A typical REST call looks like GET /users/42, returning JSON like { “id”: 42, “name”: “Alex” }. For writes you use POST, PUT, PATCH, or DELETE, guided by resource paths. REST shines when the API is stable, the data shape is predictable, and clients are varied. ...

Web3, Blockchain, and the Future of the Web Web3 is a family of ideas that aims to put people in control of their online data and connections. It uses blockchain and smart contracts to run programs without a central gatekeeper. This can lead to more open software and user-owned data. For many users, Web3 could mean apps that feel fair and private. Your digital identity could move with you across apps because you hold verifiable credentials. Payments and access rules could be managed by contracts that act when conditions are met. In daily use, this means wallets, credentials, and automated payments. ...

Web3 and Blockchain: Beyond Bitcoin to Real-World Apps Web3 and blockchain are often linked to Bitcoin, but the technology behind them is much broader. Web3 aims to give users more control, transparency, and automation through open networks and programmable contracts. When people can verify information without a trusted middleman, new services emerge that are faster, cheaper, and more resilient. Real-world use cases show how this works. In supply chains, a product’s journey from factory to store can be recorded on a shared ledger. Each step is time-stamped and difficult to alter, helping brands prove authenticity and reduce fraud. Digital identity lets you prove who you are without revealing unnecessary data, putting you back in control. Decentralized finance, or DeFi, enables lending, saving, and payments across borders with fewer middlemen. Asset tokenization turns real assets like real estate or art into digital shares, opening access to more people. ...

Web3 and Blockchain Beyond Cryptocurrency Web3 and blockchain are often linked to crypto prices, but their core value lies in trust, ownership, and open networks. A blockchain is a shared ledger that records transactions across many computers, making it hard to tamper with history. Web3 apps run on these networks and put users in control of data and actions. This shift changes how we use online services. Instead of relying on a single company to store and manage data, you hold digital keys, verify actions with smart rules, and participate in community decisions. ...

WebRTC is a newer set of browser technologies that makes audio, video, and data sharing possible directly in the web page. Together, they let people talk, see, and work together without installing extra software. ...
