A brief introduction of zora network 
Part 1 :

Zora Network is a layer 2 built on top of Ethereum. 
But what does that mean?
 
Layer 2 (L2) refers to a separate network that extends the capabilities of Ethereum while allowing users to leverage its advantages and introduce improvements and enhancements.

Part 2
Layer 2 networks alleviate the transactional burden on Ethereum by handling transactions offchain. These offchain transactions are then aggregated and posted back to the Layer 1 blockchain in, referred to as proofs.These proofs ensure the security and provability of all transactions conducted on the Zora Network
