What Is SKALE?

TL;DR

SKALE is made up of a potentially unlimited number of blockchains, called SKALE Chains, and operates in an integrated manner with the Ethereum blockchain. Developers can take advantage of Ethereum's security by migrating their DApps to their own SKALE chain to achieve high throughput with zero gas fees. This innovative approach addresses the scalability challenges facing the Ethereum ecosystem while maintaining compatibility with existing Ethereum-based applications.

Introduction

Ever-increasing user and developer activity often pushes the speed and capacity limits of popular blockchains. As decentralized applications gain mainstream adoption, network congestion and high transaction fees have become significant barriers to user experience. At the same time, a frictionless user experience is vital for the blockchain community to create a Web3 integrated future. SKALE is one of the projects built to support the exponential growth of decentralized applications on the Ethereum network.

The challenge of blockchain scalability has been a persistent issue in the industry. As more users interact with DApps, networks like Ethereum face congestion, leading to slower transaction times and increased gas fees. SKALE addresses these pain points by providing a layer-2 scaling solution that maintains security while dramatically improving performance metrics.

What Is SKALE?

SKALE is a network made up of scalable, interconnected, modular blockchains. It enables developers to migrate their projects from Ethereum onto one of the independent SKALE chains to achieve high throughput with zero gas fees. This architecture allows for horizontal scaling, meaning the network's capacity grows as more chains are added.

Founded in 2018 by Jack O'Holleran and Stan Kladko, SKALE was designed to improve the overall user experience in the blockchain space. Its vision is to make blockchain applications fast, easy, and free for all users. The founding team recognized that for blockchain technology to achieve mass adoption, it needed to offer performance comparable to traditional web applications while maintaining decentralization and security.

Through its Ethereum Virtual Machine-compatible blockchains, SKALE creates a fast, gas-free ecosystem to support the development of NFTs, games, DApps, and more. The platform is particularly well-suited for applications that require high transaction throughput, such as gaming, decentralized finance protocols, and NFT marketplaces.

How Does SKALE Work?

SKALE operates in an integrated manner with Ethereum while running its own consensus mechanism. This design takes advantage of Ethereum's proof-of-stake network and combines it with SKALE's pooled security model to offer high-speed, secure, and zero gas fee transactions. The dual-layer architecture ensures that applications benefit from Ethereum's battle-tested security while enjoying SKALE's performance advantages.

The network achieves this by offloading transaction execution from the Ethereum mainnet to SKALE chains, which operate as sidechains. These chains process transactions independently and can handle significantly higher throughput than the Ethereum mainnet. The security is maintained through a network of validators who stake SKL tokens and are randomly assigned to validate transactions across multiple chains.

SKALE also benefits Web3 and gaming applications in terms of cost and performance, contributing to Ethereum's ability to scale for mass adoption. For gaming applications, the zero gas fee model is particularly transformative, as it enables microtransactions and frequent on-chain interactions without imposing costs on players.

Multi-Chain Functionality

SKALE is a modular, multi-chain network. There can potentially be an unlimited number of SKALE chains that operate as independent blockchains, are interoperable, and EVM-compatible. This means users can deploy their existing Ethereum-based smart contracts directly on SKALE chains and enjoy high throughput and low latency. The modular design allows each chain to be customized for specific use cases, whether it's a gaming application requiring high transaction speed or a DeFi protocol needing complex smart contract execution.

Developers can also use SKALE chains to run smart contracts, decentralize storage, execute rollup contracts, and much more. For example, a decentralized gaming platform could use a SKALE chain to handle in-game asset transfers and gameplay logic, while a DeFi protocol could use another chain optimized for financial transactions.

SKALE has also modified the existing EVM functionality to allow for more smart contract use cases. For example, users can deploy SKALE chains with a FileStorage smart contract to store larger files, including websites, on network nodes. This feature is particularly useful for NFT projects that need to store metadata and media files in a decentralized manner. Interchain messaging also makes it possible to transfer tokens and NFTs across different SKALE chains, creating a seamless multi-chain ecosystem.

On SKALE, each blockchain is highly configurable. Users can choose to have their own SKALE chain, consensus protocol, virtual machine, and include security measures. These configurations can be tailored entirely to each user's specific needs. Another option DApps have is to join a community chain instead of having their own SKALE chain. Community chains allow multiple applications to share resources, making them a cost-effective option for smaller projects or those in early development stages.

To use a SKALE chain, developers need to pay a network subscription fee, which is delivered through a smart contract on Ethereum called the SKALE Manager. The fees will be shared with validators and delegators from the SKALE community; this architecture is how SKALE can offer zero gas fees to end-users. By pre-paying validators through subscription fees, the network eliminates the need for per-transaction gas fees, creating a more predictable cost structure for developers.

The SKALE Network

SKALE utilizes a network of decentralized nodes to create a pooled security system. Each node provides resources to multiple SKALE chains — including storage, monitoring, uptime and latency management — and provides node owners with an interface to withdraw, deposit, stake, or claim the native utility token, SKL. This pooled security model ensures that even smaller chains benefit from the collective security of the entire network.

Each SKALE chain added to the network can create more capacity while pooling security resources with the other sidechains. This design creates a network effect where the addition of new chains strengthens the overall ecosystem rather than fragmenting it.

The SKALE network consists of SKALE Manager and SKALE Nodes. SKALE Manager exists on the Ethereum mainnet as the entry point to all other smart contracts in the SKALE ecosystem, supporting the creation and destruction of SKALE chains. It acts as the coordination layer, handling chain deployment, validator assignment, and fee distribution.

SKALE Nodes are run by validators who stake a predetermined amount of SKL tokens on Ethereum and fulfill the network's hardware requirements. Once admitted to the network, they can support one or more SKALE chains. SKALE Manager will randomly assign each node to a group of 16 peer validators to ensure decentralization. The peers will then audit the node's uptime and latency. Based on their performance at the end of each network epoch, they will be rewarded with SKL tokens. This performance-based reward system incentivizes validators to maintain high-quality infrastructure.

SKALE Nodes use a virtualized sub-node architecture to allow each node to run multiple SKALE chains simultaneously. The Virtualized Subnodes are designed to be dynamic in size to facilitate the network's elasticity and are also responsible for running the SKALE EVM, SKALE consensus, and inter-chain communication. This virtualization technology is key to the network's ability to scale horizontally while maintaining efficiency.

What Is SKL?

SKL is the native cryptocurrency and utility token of SKALE. It has a total supply of 4.27 billion tokens. SKL is an ERC-777 token that is backward-compatible with the ERC-20 standard. It supports token-level delegation, a secure way of non-custodial staking. Instead of locking funds in a smart contract, users can stake SKL with a delegation key from their wallets, maintaining control of their assets while participating in network security.

SKL is used for payments on the network, including SKALE chain subscriptions. Token holders can stake SKL as validators or delegators and earn rewards. As validators, they can run nodes to validate transactions, execute smart contracts, and secure the SKALE network. This earns them SKL rewards derived from SKALE chain subscriptions. The validator role requires technical expertise and infrastructure investment, but offers higher reward potential.

If SKL holders choose to stake as delegators, they will only earn a portion of the validators' rewards. Delegation allows token holders who lack the technical knowledge or resources to run a node to still participate in network security and earn passive income. This inclusive staking model helps distribute network ownership and increases decentralization.

In addition, SKL gives token holders the right to participate in the governance of the SKALE network. Through on-chain voting, they can determine SKALE's economic parameters and the direction of its future development. Governance proposals might include changes to staking requirements, fee structures, or technical upgrades to the protocol.

How Staking SKL Benefits the Network

Staking SKL tokens is a central aspect of SKALE network functionality and creates a virtuous cycle that benefits all participants.

To deploy a new SKALE chain, developers have to stake SKL on Ethereum mainnet, which deploys a new SKALE chain on which the DApp can function. The DApp's SKL that is staked on mainnet will be rewarded to validators to confirm transactions on that chain and the validators are paid on a monthly basis. This subscription model provides validators with predictable revenue streams, encouraging long-term commitment to network security.

Because the validators are paid in advance to produce blocks, end-users don't have to compensate them, thus allowing end-users to enjoy zero gas fees. This fundamental design choice removes one of the biggest barriers to blockchain adoption — transaction costs. Users can interact with DApps as freely as they would with traditional web applications.

Additionally, SKL token holders can stake and delegate SKL to validators who run nodes that help the SKALE Network function by validating blocks, executing smart contracts, and securing the network. The staking mechanism aligns incentives across developers, validators, and token holders, creating a sustainable economic model.

The staking system also serves as a security mechanism. Validators who act maliciously or fail to maintain adequate performance can have their staked tokens slashed, creating a strong disincentive for bad behavior. This economic security model complements the technical security measures to create a robust and trustworthy network.
