About SKALE Network

What is SKALE Network

The SKALE Network is an open-source, Ethereum-native multichain network built to scale Ethereum dApps with a focus on high-throughput, fast finality, and zero gas fee transactions via the native gas token sFuel.

What problems does SKALE solve?

Poor web3 user experience

  • end-users required to pay gas fees

  • low speed and latency

  • connectivity and messaging between chains

Scalability Trilemma

  • speed

  • security

  • decentralization

Strict and ineffective blockchains

  • Lack of customization and control

  • Lack of horizontal scaling

  • Block gas limits and gas costs limiting what and how data/transactions are put on-chain

What does SKALE offer?

  • Zero gas fees - by design, developers and end-users never pay for transactions.

  • Instant finality - the fastest chain to finality. Time to finality = blocktime.

  • High performance

    • Throughput - Baseline of 400 transactions per second (tps) and up to 700 tps at peak.

    • High block gas limit - 280 million block gas limit allowing optimal throughput and complex transactions/smart contracts to be executed, like on-chain Machine Learning.

  • Purpose-built chains- app-chains and hub-chains for customization and and horizontal scaling.

  • Native bridge - Fast flexible, offering 18 second finality between chains. Direct support for popular token standards such as ERC-20, ERC-721, and ERC-1155 with additional flexibility for passing any arbitrary data through the low-level messaging protocol.

  • Native oracle - decentralized and transaction free oracle enabling developers to read off-chain data.

  • Decentralization and fault tolerance - chains supported by 16 randomly chosen and rotated SKALE Validator nodes, with a BFT tolerance of 1/3.

  • Layered Blockchain Security - unique hybrid Layer 1/Layer 2 architecture that partially derives security from Ethereum and with the performance and decentralization of a Layer 1.

How does SKALE do this?

The Network enables dApp developers to access validator-operated nodes' compute power and storage to run fast, containerized, EVM-compatible chains called SKALE Chains.

SKALE chains can exchange transactions or messages with other SKALE Chains and the Ethereum Mainnet through the native validator secured bridge (IMA), allowing dApp developers to use SKALE for powering their dApps while enabling token and message transfers to and from Ethereum or other chains.

With SKALE, dApps run zero-cost transactions on dedicated Proof-of-Stake chains distributed across a randomly chosen set of 16 nodes.

Decentralized validator organizations run and maintain SKALE Nodes, providing distributed computing power and storage to the SKALE Network.

Built on the foundation it services, SKALE Network is managed and operated by over 35 smart contracts deployed on Ethereum mainnet that make up SKALE Manager.

These smart contracts control network functions such as chain creation, validator registration, node selection, node rotation, staking, bounty payment, slashing, and more.

Network users such as validators, delegators, and dApp Developers exchange SKL tokens to provide stake and access network services.

The SKALE validator community represents over 45 independent operators running over 150 nodes, and the SKALE Mainnet has been live for over 300 days without interruption.

SKALE Network uses a unique combination of technologies and cryptographic-based approaches to achieve scalability, security, interoperability, and progressive decentralization:

Technology Impact

Pooled Validation Proof-of-Stake

Scalable security model across validators and delegators

Hybrid container architecture

Agile allocation of on-demand composable compute resources across the network

Threshold Cryptography

Supermajority signature signing with ABBA consensus supports Byzantine Fault Tolerance and resolves data-availability issues

Trusted-Execution Environment

Fast block signing and multiple chain support using threshold cryptography

Asynchronous Binary Byzantine Agreement (ABBA) Consensus

Mathematically provable, fast-finality, leaderless, and Byzantine fault tolerant

Ethereum Network

Public, open-source, and decentralized operation of the SKALE Network via SKALE Manager contracts

SKALE Chain Types [ Hubs | Apps ]

Hubs are community-operated chains that function as web3 service-layers divided by their specific use-case. (i.e., a hub for defi, a hub for gaming, a hub for NFTs, etc …​ )

App chains are SKALE chains that serve single applications.

SKALE Chain Sizes

SKALE Chains can be configured into different sizes - sizes being the amount of resource allocation that each of the 16 nodes provides. Read more here.

Tools & Compatibility

SKALE Network is designed to work with non-custodial wallets, chain agnostic API-based wallets, or those with dedicated support for the SKALE Network, monitoring platforms, and analytic solutions.

Access a SKALE Chain

If you don’t have a SKALE Chain yet, you can get started by using the public SKALE Chain, Chaos Testnet.
