Learn how to optimize a dApp by employing structs, events, and filters in Solidity and Web3.py as they relate to the ERC-721 standard. Also, learn about decentralized storage techniques. By the end of this post, readers will be able to:Explain what Solidity structs and events are and how they can be used to enhance a dApp.Use filters in Web3.py to react to events from smart contracts.Use the InterPlanetary File System (IPFS) to store immutable data off-chain in order to both save gas and ensu...
