Summary of the Transcript
In this video, NI, a Web 3 DeFi tech editor, explains the concept of resources and structs in Move, a programming language used for building decentralized applications. Move is designed to improve upon the limitations of Solidity, the language used for building Ethereum smart contracts.
NI starts by defining structs in Move, which are similar to classes in other programming languages. A struct in Move has four abilities: key, store, copy, and drop. The key ability allows a struct to be stored in the global state, while the store ability allows it to be saved under another struct. The copy and drop abilities are used to prevent digital assets from being copied or destroyed randomly.
Resources in Move are special structs that cannot be copied or dropped and must be stored. NI uses the example of a "coin" resource, which has a value of 100 and is stored under an account called "Alice". When Alice wants to transfer coins to Bob, the entire resource is transferred to Bob’s account, unlike in Ethereum where the balance is simply updated.
The video also touches on the syntax of defining a struct in Move and how resources are stored in the global state. NI mentions that a later video will cover how to create a token and perform transfer operations using existing token libraries.
Interesting Web3 Facts
- Move is a programming language developed by Aptos, a Web3 company that aims to create a more secure and scalable blockchain platform.
- Move is designed to improve upon the limitations of Solidity, such as the ability to create complex digital assets and prevent common attacks like reentrancy.
- The concept of resources in Move is inspired by the physical world, where digital assets are represented as structs with specific abilities that prevent them from being copied or destroyed randomly.
