StarkNet launched its mainnet alpha in late 2021, built by StarkWare, an Israeli company founded by Eli Ben-Sasson, a cryptography professor who had co-invented the STARK proof system. Unlike other ZK rollups that tried to be EVM-compatible, StarkNet used Cairo — its own custom programming language optimized for zero-knowledge proof generation. This was a bold bet: better performance at the cost of requiring developers to learn an entirely new language.
The Cairo bet was both StarkNet’s greatest strength and its biggest barrier. Cairo programs could generate proofs more efficiently than EVM-compatible alternatives, meaning StarkNet could theoretically scale further. But the developer ecosystem was tiny compared to Solidity. Most DeFi teams didn’t want to rewrite their protocols in a new language when they could deploy on Arbitrum or Base in an afternoon.
StarkNet’s ecosystem grew slowly but included high-quality projects. Blockchain gaming was a particular strength — Realms, Loot Survivor, and other fully onchain games chose StarkNet because its low costs and fast blocks were ideal for complex game logic. DeFi on StarkNet included Ekubo, JediSwap, and several lending protocols, though volumes remained modest compared to optimistic rollup competitors.
The STRK token airdrop in February 2024 was one of the year’s largest but, like zkSync’s, generated significant controversy over eligibility and distribution amounts. The token’s price declined through 2024 as early recipients sold. StarkNet’s long-term thesis remains intact — that purpose-built ZK execution will eventually outperform EVM compatibility — but the market is still waiting for StarkNet to prove that thesis with real-world adoption numbers. The technology is world-class. The question is whether the developer community will follow.
