Blockchain technology forms the foundation of many Web 3.0 applications, providing transparency, immutability, and trustlessness. Blockchains are decentralized and distributed ledgers that store records of transactions or data across a network of nodes. A blockchain database stores data in chronologically consistent blocks that you can delete or modify only with consensus from the peer-to-peer network. It has built-in mechanisms that prevent unauthorized transaction entries and create consistency in the shared view of these transactions. As a result, you can use it to create an unalterable or immutable ledger for tracking all types of transactions. Other key technologies driving the development of Web 3.0 are given next. You can expand blockchain technology applications through tokenization. Tokenization is the process of representing real-world or digital assets as digital tokens on a blockchain. These tokens are cryptographic representations of ownership, access rights, or other forms of value. For instance, you can represent physical and digital assets like real estate, stocks, commodities, art, music, and even in-game items.
Each token may represent a specific fraction or whole unit of the underlying asset, making it divisible and easily tradable. There are different token types in the virtual world, such as security tokens subject to securities regulations or non-fungible tokens (NFTs) representing unique, indivisible assets that don’t allow fractal ownership. WebAssembly (Wasm) is a binary instruction format for a stack-based virtual machine. It operates in a sandboxed environment within the browser, which means it cannot access the user's local filesystem. It enables high-performance code running within web browsers, which provides a foundation for decentralized applications to run efficiently across different platforms. Developers can run code at near-native speed, providing a significant boost in performance compared to traditional web technologies like JavaScript. Semantic web technologies allow applications to better understand and interpret customer data. They use linked data principles to interlink multiple datasets or publish structured data on the web. We give some examples next. With the Resource Description Framework (RDF), you can express statements as triples in the form of subject-predicate-object. These triples create a graph-based data structure representing different entities' relationships. SPARQL is a query language for querying RDF data. Web Ontology Language (OWL) is a language for defining ontologies, or formal representations of knowledge and relationships between concepts. You can use it to specify classes, properties, and instances, as well as facilitate reasoning and inferencing.
Soon enough, the cars we drive will be more than conversation starters, status symbols or ways to get from one point to the next. Instead, they'll be the next platform in a world gone wired. In-car Internet might be the way of the future, but going online behind the wheel isn't anything new. In the United States, satellite radio providers began transmitting traffic reports, weather updates and other data to their systems by the mid-2000s. Still, connected cars -- automobiles tied into the Internet and other communications networks -- are a relatively new phenomenon. Wayne Cunningham, senior editor of the Web site CNET Car Tech. Some cars, such as those equipped with the Ford Sync system, tap into the Internet connection on a driver's smartphone or a wireless USB adapter. Others, such as the 2011 Audi A8, use a separate data connection built into the car that accesses the Internet through a phone company's data service. Why are carmakers pushing for Internet connectivity in their cars?
It's not just consumer demand -- it's the car manufacturers. Cunningham says the nature of auto development cycles means the latest cars tend to lag behind the latest technology. By enabling their cars to access the Internet, adding the latest services and features requires a simple software update -- not a new lease. What can you do with in-car Internet access? Let's take a look. When it comes to in-car Internet, there are the features and services available at the moment, and then there are the fascinating concepts on the horizon. General Motors, BMW, Mini and other carmakers have developed their own customized applications. This means that once you install the app on your smartphone and connect the phone to the car's interface (through a Bluetooth connection, for example), the car displays a predefined set of applications on the car's infotainment system -- the term for the technology that enables audio, video, and Internet capabilities. Typically these functions appear on a dashboard-mounted monitor and can be controlled by manipulating knobs on a center console or by tapping areas on a touch screen.
Common functions include sending and receiving e-mails, connecting to social networks like Facebook and Twitter, trip planning and navigation, and downloading music and podcasts. According to Cunningham, the personalized streaming radio service Pandora is among the most popular application being integrated into connected cars. There are apps in development that would process data about a driver's position and offer location-based advertisements and promotions. This is a timely development: Since 2009, the U.S. Whether every concept made possible by Internet connectivity comes to market is another matter, Cunningham says, since carmakers are typically conservative about which features they include in their vehicles. What safety issues arise when cars are connected to the Internet? Read on the find out. While cars equipped with Internet could help create a safer driving experience, critics say there are hazards to going online in an automobile. One hazard is distracted driving, defined as any activity that takes a driver's focus off the road and could lead to an increased risk of a crash.
