In the crypto world, there are many decentralized projects built on blockchain technology. These projects often belong to areas such as decentralized finance (DeFi), infrastructure, blockchain gaming, and many other fields. Here are some notable examples:

1. Decentralized finance (DeFi)

• Uniswap: A decentralized exchange (DEX) on the Ethereum blockchain where users can trade tokens without intermediaries.

• Aave: A DeFi protocol that allows users to borrow and lend crypto assets without a centralized organization.

• MakerDAO: A decentralized stablecoin creation system, DAI, with a collateral-backed mechanism.

• Compound: A DeFi platform that allows users to earn interest or borrow assets using their crypto as collateral.

2. Blockchain infrastructure

• Ethereum: A decentralized platform supporting smart contracts and decentralized applications (dApps).

• Polkadot: A decentralized blockchain that connects multiple different blockchains, creating an interconnected ecosystem.

• Cosmos: Designed to facilitate communication between blockchains through the Inter-Blockchain Communication (IBC) protocol.

3. Decentralized storage

• Filecoin: A decentralized storage network where users can rent or lease storage space.

• IPFS (InterPlanetary File System): A decentralized data storage and sharing protocol that replaces traditional centralized server models.

4. Decentralized governance

• Decentraland: A decentralized virtual reality platform where users own and manage digital land.

• DAOstack: A tool for building decentralized autonomous organizations (DAOs) to manage resources and make decisions.

5. Blockchain gaming and NFTs

• Axie Infinity: A decentralized NFT game on the Ethereum blockchain where players own digital assets like Axie pets.

• The Sandbox: A decentralized platform that allows users to create, own, and monetize content and gaming experiences.

• OpenSea: A decentralized marketplace for NFTs where users can buy and sell digital assets.

6. Layer 2 protocols

• Arbitrum: A Layer 2 scaling solution for Ethereum that reduces costs and increases transaction speeds while maintaining decentralization.

• Optimism: Another Layer 2 protocol designed to support DeFi applications on Ethereum with lower fees.

7. Payment systems

• Bitcoin (BTC): The first decentralized cryptocurrency in the world, operating on a decentralized blockchain.

• Lightning Network: A decentralized Layer 2 payment protocol built on Bitcoin.

These decentralized projects are not controlled by any organization or individual, but are often based on community and decentralized governance mechanisms (DAOs). If you want to learn more about each area, I am ready to help!
