What is Starknet (STRK)?

What is Starknet (STRK)?
Starknet is a Layer 2 network built on top of Ethereum that uses zero-knowledge proofs to process thousands of transactions off-chain, then submit a single cryptographic proof to Ethereum that verifies all of them at once. The key difference from other Layer 2s: Starknet uses STARK proofs (Scalable, Transparent ARgument of Knowledge) — a specific type of proof system invented by its founders that is more efficient for large batches and doesn't require a trusted setup.
StarkWare was founded in 2018 by Eli Ben-Sasson, Uri Kolodny, Michael Riabzev, and Shahar Papini — academic cryptographers who invented the STARK proof system at the Technion (Israel Institute of Technology). Their first product was StarkEx — a customizable ZK-proof engine that powers specific applications like Immutable X and dYdX v3. Starknet is their general-purpose network where anyone can deploy smart contracts using the Cairo programming language.
The STRK token launched in February 2024 amid one of the most discussed airdrops of that year. It serves dual purposes: governance (STRK holders vote on protocol parameters) and transaction fees (you can pay Starknet gas in STRK). The launch was controversial because early allocations to investors and team members were large, and the initial tokenomics drew criticism — though the Starknet Foundation has since pursued aggressive community incentive programs.
Starknet Key Facts
How Does Starknet Work?
Starknet works by batching thousands of transactions and generating a single cryptographic proof that proves all those transactions were valid, then submitting that proof to Ethereum.
Transactions Submitted to Starknet
Users send transactions to Starknet's sequencer (a node that orders and processes transactions). Gas fees on Starknet are typically 10-100x cheaper than Ethereum mainnet since thousands of transactions share the cost of a single Ethereum proof submission.
Transactions Execute in CairoVM
Starknet runs a custom virtual machine (CairoVM) that executes Cairo programs — smart contracts written in the Cairo language. Unlike the Ethereum Virtual Machine (EVM), CairoVM is designed natively for proof generation, making it far more efficient at producing STARK proofs. EVM-equivalent execution (via Kakarot) is also being developed.
STARK Proof Generated
A prover node takes a batch of transactions and generates a STARK proof — a mathematical certificate that says "all these transactions were computed correctly." This proof is much smaller than the raw transactions and can be verified by anyone quickly. STARK proofs don't require a trusted setup (unlike SNARKs), making them more transparent.
Proof Submitted to Ethereum
The STARK proof is submitted to a verifier smart contract on Ethereum. Ethereum checks the proof — if it's valid, the state update is accepted. This final settlement on Ethereum gives Starknet the full security of Ethereum: to attack Starknet, you'd need to attack Ethereum itself.
STARK vs SNARK: What's the Difference?
Both are types of zero-knowledge proofs, but they have important differences. Starknet uses STARKs; ZKsync uses SNARKs. Here's what matters for regular users:
| Property | STARK (Starknet) | SNARK (ZKsync, others) |
|---|---|---|
| Trusted setup | Not required — fully transparent | Required — ceremony must be done honestly |
| Quantum resistance | Yes — hash-based, quantum secure | No — elliptic curve crypto vulnerable to quantum |
| Proof size | Larger — higher verification gas on Ethereum | Smaller — cheaper to verify on Ethereum |
| Scale efficiency | Better — cost per transaction falls as batch grows | Good but less efficient at very large scale |
| EVM compatibility | Not native (Cairo VM; Kakarot adds EVM) | Usually native EVM compatibility |
Plain English summary: STARKs are more transparent and scale better for very large applications. SNARKs produce smaller proofs that are cheaper to verify. For everyday users, the main practical difference is that Starknet uses Cairo (not Solidity), meaning it has fewer compatible dApps today — but very strong technical fundamentals for the long term.
STRK Tokenomics
The STRK token launched in February 2024 with 10 billion total supply. The distribution was heavily criticized for allocating large portions to insiders with relatively short lock periods. Here's the breakdown:
| Allocation | % of Supply | Notes |
|---|---|---|
| Starknet Foundation | 50.1% | Ecosystem grants, developer incentives, community programs |
| StarkWare (company) | 17% | Core development team, 4-year vesting |
| Early Investors | 17% | VCs and angels from early funding rounds |
| Community Grants | 9% | Developer ecosystem, DeFi incentives, protocol partners |
| Initial Airdrop | 6.9% | Ethereum developers, Starknet users, Ethereum stakers |
The airdrop criticism: Only 6.9% went to the community airdrop, while 34% went to StarkWare and investors. Many in the community felt this centralized too much supply in insider hands. The Foundation has responded with aggressive DeFi incentive programs designed to distribute more STRK to active users over time.
Starknet History
StarkWare founded by cryptographers
Eli Ben-Sasson, one of the co-inventors of ZK-SNARKs, founded StarkWare along with Uri Kolodny after developing the STARK proof system academically. They received early backing from Paradigm, a16z, and Sequoia. The company's mission: scale Ethereum using cryptographic proofs rather than reducing security.
StarkEx powers dYdX and Immutable X
StarkEx — the application-specific version of StarkWare's technology — launched to power specific apps. dYdX used it for their perpetuals trading platform, processing millions of orders cheaply. Immutable X used it for NFT minting and trading for games like Gods Unchained. StarkWare became the most used ZK-rollup technology by volume.
Starknet Alpha and permissionless launch
Starknet Alpha launched on Ethereum mainnet, allowing any developer to deploy Cairo smart contracts. This was different from StarkEx — instead of one app, it's a general-purpose network. The Cairo programming language matured, and a growing ecosystem of DeFi, NFT, and gaming dApps deployed. Full mainnet went permissionless in November 2023.
STRK token launches — ATH of $4.50
STRK launched February 20, 2024 with a community airdrop, hitting an ATH of ~$4.50 within days on L2 bull market momentum. The tokenomics triggered debates about insider concentration. Starknet Foundation responded with DeFi Spring — a $40M incentive program to attract liquidity and active users to the network via STRK rewards.
Decentralization and Kakarot EVM
Starknet began decentralizing its sequencer (the node that orders transactions) and prover. Kakarot — an EVM implemented in Cairo — progressed toward allowing Solidity developers to deploy to Starknet directly. Major DeFi protocols like Uniswap v3 deployed on Starknet. The network processed hundreds of millions of transactions monthly.
Risks and Considerations
Cairo learning curve
Starknet requires developers to use Cairo — not Solidity. This means fewer developers can build on Starknet today compared to EVM-compatible chains. While Kakarot is bringing EVM compatibility, it's not yet mature, limiting the pool of developers and dApps.
Centralized sequencer
Starknet's sequencer is still operated by StarkWare. This means a single company can theoretically censor transactions or go offline, disrupting the network. Decentralizing the sequencer is a multi-year process — the risk is real today but decreasing over time.
Insider token concentration
StarkWare and investors together control 34% of STRK. As vesting schedules unlock, significant sell pressure from these insiders is a structural risk. The community airdrop (6.9%) was small relative to the insider allocation, reducing retail investor goodwill.
Intense L2 competition
Starknet competes with ZKsync, Polygon zkEVM, Scroll, and Ethereum's growing L2 ecosystem. ZKsync and Polygon have EVM compatibility out of the box. Starknet's technical advantages may not be enough if developers prefer EVM-compatible alternatives with better tooling and larger existing ecosystems.
