Starknet is an Ethereum layer-2 that uses validity proofs — STARKs — so every batch of transactions arrives on Ethereum with a mathematical proof it was executed correctly, rather than a challenge window like optimistic rollups use. Its contracts are written in Cairo, a purpose-built language, which makes it powerful for proof-heavy work but harder to port existing Solidity code onto. Starknet is a validity rollup: rather than assuming transactions are correct and allowing challenges, it proves them cryptographically before posting to Ethereum, so there is no multi-day withdrawal window. It uses its own language, Cairo, built for provable computation, which raises the barrier for developers but allows things Ethereum-compatible rollups cannot do as efficiently. That choice defines the project — deeper technology, smaller developer pool. On this map STRK is a mid-cap Layer 2 whose supply unlock schedule has been a visible factor in its price history.
What is a validity rollup?
One that proves the correctness of its transactions with a cryptographic proof before posting to the base chain, rather than assuming validity and allowing a challenge period.
Why does Starknet use Cairo instead of Solidity?
Cairo is designed for provable computation, which is what makes efficient validity proofs possible. The trade-off is that developers must learn a new language.
Are withdrawals faster than on optimistic rollups?
Yes in principle, because there is no fraud-proof challenge window to wait out — finality depends on proof generation and verification instead.
What is STRK used for?
It pays transaction fees on the network, is staked, and is used in governance.
Market cap decides how big a bubble is drawn, so rank is what places STRK on the map relative to the rest of its sector.
