What are digital assets?
Digital assets are electronic records that represent a variety of real-world assets. These assets can be divided into two main categories: fungible and non-fungible. Fungible digital assets are interchangeable and have the same value, like cryptocurrencies. Non-fungible digital assets are unique and have their own distinct value, like digital art or collectibles.
How are digital assets stored in the block chain?
Digital assets are stored on the blockchain in a digital wallet. A digital wallet is a software program that stores private and public keys and interacts with various blockchain networks. These digital wallets can either be stored online or offline, also known as hot or cold storage respectively.
What are smart contracts?
Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. They are executed automatically once the conditions specified in the contract are met. This allows for faster, cheaper, and more secure transactions between parties.
How do smart contracts work?
Smart contracts work by executing the code written into them automatically once the specified conditions are met. The code is stored on the blockchain, which ensures that the contract is secured and can't be tampered with. Once the contract is deployed onto the blockchain, it becomes immutable, meaning it can't be changed or deleted.
In conclusion, digital assets and smart contracts are two of the most revolutionary aspects of blockchain technology.
