**Oasis** is a layer 1 blockchain built for scalability and confidential computing. It features **Sapphire**, the first confidential Ethereum Virtual Machine (EVM), enabling Web3 and decentralized AI developers to create dApps with built-in smart privacy on Oasis or other EVM-compatible chains. The **ROSE** token serves as the native asset of the Oasis Network, facilitating gas fees, staking, delegation, and governance. Oasis employs a layered architecture, providing an efficient environment for DeFi, AI, GameFi, NFTs, the metaverse, data tokenization, and DAO governance. Additionally, the network natively supports rollups at the consensus layer. **Smart Privacy** Advanced decentralized applications demand smarter privacy solutions. Oasis addresses this need by offering Smart Privacy—a flexible, customizable confidentiality framework designed for Web3 and AI. Unlike rigid and complex existing tools, Oasis provides adaptable privacy solutions. With technologies like the Sapphire runtime and the Oasis Privacy Layer (OPL) for EVM-compatible chains, Oasis brings advanced confidentiality to Web3 developers, even those not building directly on the Oasis Network. For applications on other blockchains, OPL enables seamless integration of Sapphire’s privacy features at any layer of Web3. By offering a spectrum of customizable confidentiality options, Oasis is transforming how developers approach privacy and expanding the tools available for secure Web3 and AI applications. **Layered Architecture** The Oasis Network was designed with a clear separation between its consensus and compute layers. The compute layer supports privacy-preserving computation through specialized runtime environments, while the consensus layer—secured by a proof-of-stake (PoS) mechanism—handles transaction validation and network-wide agreement. The compute layer consists of multiple parallel runtimes (ParaTimes), each optimized for specific computational needs. This modular structure allows decentralized applications (dApps) to run efficiently on Oasis or integrate Oasis technology while operating on other networks. Each ParaTime connects to the Oasis consensus layer, ensuring security while enabling independent evolution. Developers and users retain full control over execution and data confidentiality. **Efficient Confidentiality** Oasis stands out by balancing efficiency and confidentiality. Whether processing large-scale smart contract data or simple transactions, Oasis ensures consistent performance while optionally supporting end-to-end encryption. By separating consensus and computation, Oasis allows execution environments to operate without interference. Consensus is handled independently, accessed only when needed by applications on the compute layer. Unlike networks that force a trade-off between privacy and efficiency, Oasis delivers both—enabling high-performance execution without compromising security. The Oasis Network ROSE token has a circulating supply of 6.5 billion tokens and a maximum total supply of 10 billion ROSE. The initial distribution of tokens was allocated as follows: - **23.5%** – Staking rewards - **23%** – Backers - **5%** – Strategic partners and reserve - **18.5%** – Community and ecosystem - **10%** – Foundation endowment - **20%** – Core contributors ROSE serves multiple functions within the Oasis Network, including: - Paying transaction fees - Staking and delegation - Governance participation on the consensus layer - Covering transaction and computation costs on the compute layer Oasis utilizes a proof-of-stake (PoS) consensus mechanism, maintained by a decentralized network of validator nodes operated by independent users globally. The network employs fraud proofs to detect discrepancies, securing its separate compute and consensus layers. For confidential runtimes such as Sapphire and Cipher, Oasis requires nodes to use a Trusted Execution Environment (TEE). This secure computing technology functions as a black box for smart contract execution, leveraging encrypted memory and remote attestation. The process involves: 1. Inputting encrypted data alongside the smart contract and validity proofs. 2. Validating, decrypting, and processing the data within the TEE. 3. Encrypting the contract data before it exits the TEE. This approach minimizes friction for developers and users while ensuring data confidentiality. Sensitive information remains protected and is never exposed—even to node operators or application developers. The Oasis Network is developed and maintained by a decentralized community of engineers and developers. Many of its core contributors hold PhDs and specialize in computer security and cryptography. The network is supported by industry backers and contributors, with a $235 million Ecosystem Fund dedicated to fostering growth. Additionally, the Oasis Foundation offers grants to support projects building on the network. The Oasis compute layer supports multiple parallel runtime environments, known as ParaTimes, enabling Web3 developers to build decentralized applications on existing runtimes or create their own. Each ParaTime can be customized to meet specific application needs, including privacy settings, staking requirements, and development languages. Three key ParaTimes operate on Oasis: - **Sapphire** – The first confidential EVM-compatible runtime, allowing developers to build EVM-based dApps with smart contracts that range from fully private to entirely public. It combines the familiarity of Ethereum development with Oasis Smart Privacy technology. - **Emerald** – A high-performance, EVM-compatible runtime designed to address gas fees and cross-chain interoperability, ensuring smooth user experiences without performance delays. - **Cipher** – A WebAssembly (WASM)-based privacy-enabled runtime where developers can use Rust to build confidential dApps. Beyond native Oasis development, the **Oasis Privacy Layer (OPL)** extends Sapphire’s privacy features to any EVM network, allowing developers to integrate privacy into existing dApps without migrating away from their native blockchain. For users and developers on the Oasis Network, several tools enhance the experience: - **Oasis Wallet** – A non-custodial wallet for managing digital assets on the network, with support for secure custody solutions and fiat on-ramps. - **Oasis Explorer** – A tool for analyzing on-chain activity across all ParaTimes, providing insights into network growth and development. - **Oasis Nexus** – The official indexer for the network, processing blockchain data into an indexed SQL database and offering a JSON-based API for explorers and wallets. These resources empower developers and users to interact seamlessly with the Oasis ecosystem. **Revolut Crypto Quiz Answers (Learn & Earn Program)** Revolut’s Learn & Earn program allows users to test their cryptocurrency knowledge through quizzes and earn rewards upon completion.
