In the world of blockchain and crypto, assets refer to any type of digital value that can be owned or traded within a blockchain network. These can be cryptocurrencies like Bitcoin, which is a form of digital money, or tokens that represent real-world assets like gold or property.

Assets are used whenever a transaction or exchange of value occurs on the blockchain network. Like when someone sends Bitcoin, a company tracks the movement of goods using supply chain tokens, or an investor buys tokens that represent ownership of property.

Assets are important because they represent the value being transferred or tracked on the blockchain network. Without assets, there is no way to represent the value of cryptocurrencies, tokens, or digital property exchanged or owned on the network.

Assets can be created using blockchain technology. For cryptocurrencies like Bitcoin, new assets are created through mining. For real-world asset tokens, they are created by companies/organizations using blockchain. For unique digital properties like NFTs, they are created by game/platform developers.
