Compound is a decentralized finance (DeFi) lending protocol on the Ethereum blockchain that enables users to lend and borrow cryptocurrencies without middlemen. Utilizing smart contracts, Compound allows users to earn interest by supplying cryptocurrencies, and borrowers can secure loans by providing collateral. Its native token, COMP, is used for governance, allowing the community to propose and vote on protocol changes, fostering a decentralized, adaptable system.

Users benefit from Compound by lending their assets to earn interest or by borrowing through over-collateralization. Lenders earn from interest rates set algorithmically by the protocol based on supply and demand, providing a passive income stream. Borrowers gain access to liquidity without selling their assets, benefiting from price exposure continuity. The decentralized nature of Compound and its community governance ensures security, flexibility, and transparency.

Compound operates without traditional financial intermediaries, reducing transaction costs and increasing accessibility. The protocol's decentralized structure, powered by smart contracts and governed by COMP token holders, ensures transparency and security. Unlike traditional services, it offers real-time interest rates based on supply and demand, providing higher flexibility. Additionally, borrowers in the Compound ecosystem retain exposure to their crypto assets, which is not feasible with traditional loans.

Compound ensures security and liquidity through its over-collateralization requirement, which obliges borrowers to deposit collateral exceeding their loan value. This mechanism protects the protocol against defaults. Furthermore, its smart contracts are rigorously audited to reinforce security. The dynamic interest rate model, determined algorithmically, optimizes liquidity and encourages participation from both lenders and borrowers, supporting a balanced financial ecosystem.

Compound uses its native COMP token for governance, empowering token holders to propose, debate, and vote on protocol upgrades and changes. This decentralized governance model allows the community to partake in decision-making processes, ensuring the platform evolves according to user needs. The system's resilience is bolstered by this model, allowing for democratic adaptation in the rapidly changing DeFi landscape.

Users might face issues such as understanding the collateralization process or experiencing Ethereum network congestion affecting transaction speeds. To resolve these, it's important to thoroughly read the Compound documentation, which explains borrowing mechanics and collateral ratios. For network-related issues, using Ethereum scaling solutions or considering network activity timing can reduce delays and costs. Additionally, active community forums and support channels offer assistance for troubleshooting.
