Starknet is a Validity Rollup Layer 2. It provides high throughput, low gas costs, and retains Ethereum Layer 1 levels of security. how can this be cheap? In this strategy, each computation of a solution becomes a one-time event which does not require replication by society. In a similar vein, Starknet scales Ethereum by replacing heavy L1 computation with lighter (hence cheaper!) L1 verification using STARK proofs computed off-chain. H ow it works With the above analogy in mind, the time is ...
