React Native combines the best parts of native development with React, a best-in-class JavaScript library for building user interfaces. Use a little—or a lot. You can use React Native today in your existing Android and iOS projects or you can create a whole new app from scratch. React primitives render to native platform UI, meaning your app uses the same native platform APIs other apps do. Many platforms, one React. Create platform-specific versions of components so a single codebase can share code across platforms. With React Native, one team can maintain two platforms and share a common technology—React. React Native lets you create truly native apps and doesn't compromise your users' experiences. It provides a core set of platform agnostic native components like View, Text, and Image that map directly to the platform’s native UI building blocks.

The core of extensible programming is defining functions. Python allows mandatory and optional arguments, keyword arguments, and even arbitrary argument lists. Whether you're new to programming or an experienced developer, it's easy to learn and use Python. Python can be easy to pick up whether you're a first-time programmer or you're experienced with other languages. The following pages are a useful first step to get on your way to writing programs with Python! The community hosts conferences and meetups to collaborate on code, and much more. Python's documentation will help you along the way, and the mailing lists will keep you in touch. The Python Package Index (PyPI) hosts thousands of third-party modules for Python. Both Python's standard library and the community-contributed modules allow for endless possibilities.

WalletConnect is an open source protocol for connecting decentralized applications to mobile wallets with QR code scanning or deep linking.

Bitcoin is an innovative payment network and a new kind of money. Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system. Bitcoin transactions are secured by mathematics and energy. Cryptographic signatures prevent other people from spending your money. Energy spent by proof of work (PoW) prevents other people from undoing, rearranging or losing your transactions. So long as you take the required steps to protect your wallet, Bitcoin can give you control over your money and a strong level of protection against many types of fraud.

Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design and produces software that runs lightning-fast. Swift is the result of the latest research on programming languages, combined with decades of experience building Apple platforms. Named parameters are expressed in a clean syntax that makes APIs in Swift even easier to read and maintain. Even better, you don’t even need to type semi-colons. Inferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces. To best support international languages and emoji, Strings are Unicode-correct and use a UTF-8 based encoding to optimize performance for a wide-variety of use cases. You can even write concurrent code with simple, built-in keywords that define asynchronous behavior, making your code more readable and less error-prone.

TypeScript adds additional syntax to JavaScript to support a tighter integration with your editor. Catch errors early in your editor. TypeScript code converts to JavaScript, which runs anywhere JavaScript runs: In a browser, on Node.js or Deno and in your apps. TypeScript understands JavaScript and uses type inference to give you great tooling without additional code. TypeScript was used by 78% of the 2020 State of JS respondents, with 93% saying they would use it again. The most common kinds of errors that programmers write can be described as type errors: a certain kind of value was used where a different kind of value was expected. This could be due to simple typos, a failure to understand the API surface of a library, incorrect assumptions about runtime behavior, or other errors.

Rust is blazingly fast and memory-efficient: with no runtime or garbage collector, it can power performance-critical services, run on embedded devices, and easily integrate with other languages. Rust’s rich type system and ownership model guarantee memory-safety and thread-safety — enabling you to eliminate many classes of bugs at compile-time. Rust has great documentation, a friendly compiler with useful error messages, and top-notch tooling — an integrated package manager and build tool, smart multi-editor support with auto-completion and type inspections, an auto-formatter, and more. Whip up a CLI tool quickly with Rust’s robust ecosystem. Rust helps you maintain your app with confidence and distribute it with ease. Use Rust to supercharge your JavaScript, one module at a time. Publish to npm, bundle with webpack, and you’re off to the races.

Ethereum is the community-run technology powering the cryptocurrency, ether (ETH) and thousands of decentralized applications. Ethereum is a technology that's home to digital money, global payments, and applications. The community has built a booming digital economy, bold new ways for creators to earn online, and so much more. It's open to everyone, wherever you are in the world – all you need is the internet. Today, billions of people can’t open bank accounts, others have their payments blocked. Ethereum's decentralized finance (DeFi) system never sleeps or discriminates. With just an internet connection, you can send, receive, borrow, earn interest, and even stream funds anywhere in the world. Today, we gain access to 'free' internet services by giving up control of our personal data. Ethereum services are open by default – you just need a wallet. Stake your ETH to become an Ethereum validator.

BNB Smart Chain (BSC) is a blockchain platform developed by Binance, designed to enable decentralized applications (dApps) and smart contracts. It operates as a parallel chain to Binance Chain, combining high-speed transactions with the programmability of Ethereum-compatible smart contracts. BSC uses a Proof-of-Staked-Authority (PoSA) consensus mechanism, which enhances scalability and efficiency while reducing transaction costs. It is compatible with the Ethereum Virtual Machine (EVM), allowing developers to easily port dApps and projects from Ethereum. BSC has become a popular choice for decentralized finance (DeFi), gaming, and NFT ecosystems, offering users a fast, low-cost, and secure platform for blockchain-based innovations.

StarkEx generates validity proofs, to ensure that only valid data resulting from computations performed with integrity, is committed on-chain. The secret to StarkEx’s massive scaling capabilities lies in the uneven division of computation between its off-chain prover and the on-chain verifier. StarkEx powers self-custodial dApps, and employs innovative anti-censorship mechanisms to ensure that users’ funds always remain in their custody. StarkEx has been developed to serve a diverse range of user and application needs. Applications that wish to integrate with StarkEx can arrive on Mainnet within a few weeks time, depending on the maturity of their off-chain Operator node. With validity proofs, state updates are considered finalized as soon as they are verified on-chain. This can be a matter of hours, as compared to fraud proofs that can be finalized only after the dispute period.
