    Study Notes

    Front-End Technologies in Blockchain dApps

    • The primary purpose of Front-End technologies is to create a user interface for users to interact with the blockchain.

    Characteristic of Backend Code

    • The backend code of dApps running on a decentralized network is called smart contracts.

    Benefits of dApps

    • No owners is a benefit of dApps, meaning that there is no central authority controlling the application.
    • NOT listed as a benefit of using dApps: centralized control.

    Drawbacks of dApps

    • One of the drawbacks of using dApps is the immutability of data, which means that once data is written to the blockchain, it cannot be altered or deleted.
    • Another drawback is related to scalability, as dApps may not be able to handle a large volume of users.

    Blockchain Technology

    • The immutable nature of blockchain technology means that the 'right to be forgotten' does not exist in Canada.

    Characteristics of dApps

    • Immutability is a characteristic of dApps that ensures they cannot be altered once deployed on the Ethereum network.
    • Turing complete implies that dApps can theoretically solve any computational problem, making them highly versatile and programmable.

    Front-End Development of dApps

    • JavaScript is typically involved in the Front-End development of blockchain dApps, but Machine Learning is NOT typically involved.
