QAs about ZKP and ZK-sync #1

Open yeecai opened 1 year ago

1. What is ZKP?

Zero-knowledge proof (ZKP) is a technique that allows one to prove who knows a secret without revealing the secret.

2. What's the relationship between ZK-sync and ZKP?

Layer2 scaling solution that uses ZKP to do verification, which has lower gas fees and faster transaction times compared to Ethereum mainnet.

3. How does ZKP contribute?

Provide fast & secure transactions without extensive computation:

Off-chain computation
[ ] how?
Minimal data transfer: ZKP needs fewer data for verifying a transaction.
ZK Proofs of correctness: ZKP can verify without revealing transaction details which makes it a more secure way of roll-up
Scalability: ZK-based systems have higher TPS(transaction per second), which can increase the scalability significantly.

[ ] ZK-rollup vs ZK-sync

yeecai commented 1 year ago

ZK-rollup up to 100x more TPS than the mainnet: how? does it mean that ZK-rollup is more efficient than ZK-sync?
