What Is Starknet
Starknet is a permissionless Layer 2 validity rollup built on Ethereum. It aims to scale Ethereum while preserving its core principles of decentralization, transparency and security.
It was developed by StarkWare, a company co-founded in 2018 by zero-knowledge researcher Eli Ben-Sasson and others. An alpha mainnet launched in late 2021, and the STRK token became transferable in early 2024 alongside an airdrop.
Scaling With STARKs
Starknet batches many transactions off-chain and produces a cryptographic proof called a STARK, which is posted to Ethereum. Ethereum verifies the proof instead of re-executing every transaction, which can lower fees and raise throughput.
Developers write smart contracts in Cairo, a language designed for provable computation, and every account is a smart contract through native account abstraction. The v0.14.0 upgrade in 2025 introduced a decentralized sequencer architecture.
STRK and Its Ecosystem
STRK has a total supply of 10 billion tokens and is used for governance, paying transaction fees and participating in consensus. Allocations for early contributors and investors unlock gradually on a preset schedule.
STRK staking began in late 2024, and Bitcoin staking was later added to consensus, creating a dual-token security model using STRK and BTC. The ecosystem includes DeFi protocols, games, wallets and other applications.
Strengths and Risks
STARK proofs require no trusted setup, are considered relatively resistant to quantum attacks, and can verify large amounts of computation efficiently. Its decentralization roadmap, including sequencers and provers, is progressing in stages.
On the other hand, competition among Layer 2 networks is intense, and Cairo differs from common Ethereum tooling, which adds a learning curve. Ongoing token unlocks that increase supply, along with technical and regulatory uncertainty, are also factors to consider.
