Learn how optimistic rollups assume transactions are valid and use fraud proofs for dispute resolution. Explore challenge periods, sequencer design, and Layer 1 settlement.
Start Quest →Explore zero-knowledge proofs and how they enable instant transaction finality with cryptographic guarantees. Dive into SNARKs, STARKs, and proof generation.
Start Quest →Understand off-chain data availability and the trade-offs between security, cost, and throughput. Compare Validium, Volition, and hybrid approaches.
Start Quest →A rollup is a Layer 2 scaling solution that executes transactions off the main blockchain (Layer 1) but posts transaction data on-chain. This approach inherits the security of the base layer while dramatically increasing throughput and reducing costs.
Rollups bundle — or "roll up" — hundreds of transactions into a single batch, compressing the data before posting it to the main chain. The key innovation is separating execution from data availability and consensus.
