SKALE enhances Ethereum's scalability through a network of interoperable AppChains, offering a unique architecture that boosts performance and retains security.
SKALE AppChains are Ethereum Native, meaning they run on EVM and enable developers to author smart contracts in Solidity. Developers can build and deploy their applications using the same tools and standards of the Ethereum mainnet.
SKALE empowers high throughput and instant finality, addressing two significant scalability challenges Ethereum currently faces. A study by Dartmouth Blockchain tested the performance of 8 popular blockchains with SKALE emerging as the top-performing chain with a TPS of 397.7 and a TTF of 1.46 seconds per chain.
SKALE ensures instant finality for all transactions, effectively eliminating challenges like MEV, time bandit attacks, and chain reorganizations that have been persistent issues for prior-generation blockchains struggling with latency and slow finality.
SKALE's modular architecture establishes an elastic network of configurable chains, enhancing agility beyond traditional monolithic L1s while retaining a strong security foundation. This design permits dynamic chain creation and node reassignments, ensuring resilience against potential threats. In this framework, SKALE Chains emerge as effective shards distinguishing themselves from conventional sidechains.
SKALE's architecture supports on-chain file storage for comprehensive website and application data storage hosting and also enables direct on-chain integration of advanced technologies such as AI and Machine Learning. SKALE enables free minting and trustless on-chain storage of NFTs which bypasses the need for reliance on centralized cloud hosting platforms like AWS.
SKALE FUEL, or sFUEL, is SKALE Network's solution for eliminating traditional blockchain gas fees. This valueless "gas" token powers operations and transactions on each SKALE chain, obtained for free via the sFUEL Station faucet. Besides providing cost-efficiency, sFUEL also enhances network security by rate-limiting transactions to prevent potential DDoS attacks.
SKALE presents a unique multichain network where individual chains, while independently optimized for performance, benefit from a collective fortress of security. This distributed design allows each validator node to operate concurrently on up to eight chains. In addition, these nodes are not static but randomly assigned and frequently rotated, creating a dynamic environment that significantly enhances resistance against collusion attempts.
A unique aspect of SKALE lies in its user-centric model aimed at greatly enhancing the Web3 user experience. SKALE eliminates the concept of gas fees for end-users, introducing instead a flat subscription model. Developers, protocols, or even enterprises can establish a SKALE chain by paying a monthly fee, which offers them the advantage of hosting and developing dApps on a dedicated chain.
SKALE's groundbreaking architecture introduces App Chains, which moves away from the 'one-size-fits-all' approach typical of blockchain networks. SKALE App Chains are customized for specific applications. This innovation offers enterprises the advantage of creating permissioned or permissionless blockchains tailored to their requirements. Through chain customization, enterprises can boost performance, with each App-chain functioning independently for consistent performance, even under high demand.
Alongside App-chains, SKALE introduces Hub-chains to serve an entire ecosystem of needs. Hub-chains enhance inter-chain communication and transactions, providing a holistic solution that addresses a diverse array of requirements within the blockchain ecosystem. They facilitate smoother and more efficient operations across multiple App-chains, promoting synergy and interconnectivity.
The Levitation Protocol introduces a decentralized Zero-Knowledge (ZK) scaling solution into the SKALE architecture. Offering interoperability with existing ZK rollups, the protocol enhances the SKALE app-chain network's flexibility and security, fostering decentralization across multiple ZK rollups on a single Levitation-enabled chain.
SKALE Connect is an innovation that expands user growth by leveraging SKALE's native oracle. Users can seamlessly interact with their NFT assets from any EVM network on the SKALE Network. SKALE Connect streamlines asset verification across EVM networks, removing the need for bridging or asset locking. It fosters a rich NFT experience and offers fresh opportunities for ecosystem expansion.
SKALE G, a new “Layer 1 Megachain”, is designed to be the world's fastest and most scalable decentralized Layer 1 blockchain. Fortified by ZK Rollups and linked to Ethereum via Layer 2 ZK hooks, SKALE G enables App-Chains to enjoy gas-free transactions or opt for configurable Layer 2 ZK solutions.
