Zkporter
Starknet: a decentralized, permissionless and censorship-resistant STARK-powered L2 ZK-Rollup that supports general-computation over Ethereum.【Building Dapps】
StarkEx: L2 scalability engine, which can handle complex trading logic (spot trading, derivatives, NFTs) as well as payments
Default: ZK prover (under a minute)
Validators: be responsible for packing transactions into blocks and generating zkp for them. They participate in the consensus and must.
Guardians: nominate honest validators,monitor p2p transaction traffic, detect censorship behavior.【开始是不是随机的,开始的validator是怎么选择的】
Cairo’s Generic Proof Service (GPS)【细化】 first ,then then verified on-chain

zkPorter【decentrailzied】:transaction settlement method based on each account,DA is motivated by the “Guardian” of the zkSync native token to provide security
Volition system【centrailzied】: choose rollup scheme (data availability on the chain) or the validium scheme (data availability off the chain) for each transaction
