Ethereum based applications are applications that use the Ethereum blockchain to run smart contracts, which are self-executing agreements that can enforce rules and logic without intermediaries. Ethereum based applications can enable various use cases, such as:

• Voting systems that are transparent, secure, and verifiable

• Banking systems that are faster, cheaper, and more inclusive

• Shipping systems that can track cargo and prevent fraud

• Agreements that can automate payments, escrow, and arbitration

• Finance that can offer lending, borrowing, trading, and investing without intermediaries

• Web browsing that can protect privacy and reward users for their attention

• Gaming that can create digital assets and economies

• Advertising that can eliminate fraud and middlemen

• Identity management that can give users control over their own data

• Supply chain management that can increase efficiency and transparency

Some examples of popular Ethereum based applications are:

• Uniswap: a decentralized exchange that allows users to swap tokens without intermediaries or fees

• Brave: a web browser that blocks ads and trackers and rewards users with Basic Attention Tokens (BAT) for viewing ads or content

• CryptoKitties: a game that allows users to collect, breed, and trade digital cats that are unique and non-fungible tokens (NFTs)

• MakerDAO: a protocol that allows users to create and manage a stablecoin called DAI, which is pegged to the US dollar and backed by collateral

• OpenSea: a marketplace that allows users to buy and sell NFTs, such as art, music, domain names, and collectibles
