This FAQ explains DeFiChain (often searched as 'defichain la gi' in Vietnamese) for absolute beginners. You'll learn what DeFiChain is, how it works, its native token, pros and cons, and how it compares to Ethereum.

Defichain la gi?

Defichain la gi means 'What is DeFiChain?' in Vietnamese. DeFiChain is an open-source blockchain built specifically for decentralized finance (DeFi) applications. It leverages the security of the Bitcoin network while offering fast, low-cost financial services like lending, borrowing, staking, and decentralized exchange (DEX).

The project was launched in 2020 by Julian Hosp and U-Zyn Chua. Its goal is to provide a dedicated platform for DeFi, avoiding the high fees and congestion of general-purpose blockchains like Ethereum.

How does DeFiChain work?

DeFiChain uses a Proof-of-Stake consensus mechanism and a network of masternodes to validate transactions. Each DeFiChain block is anchored to a Bitcoin block, giving it the security of Bitcoin while remaining fast and inexpensive. This allows the network to support on-chain DeFi operations such as decentralized trading, lending, and minting of tokenized assets.

Unlike Ethereum, DeFiChain does not use general-purpose smart contracts. Instead, it uses a fixed set of built-in DeFi modules, which makes the system simpler and less vulnerable to certain smart-contract risks.

What are the main features of DeFiChain?

DeFiChain's main features are designed directly into the blockchain, enabling a complete DeFi experience without leaving the network. The core features include:

  • A native decentralized exchange (DEX) for token swaps
  • Liquidity mining to earn yield on token pairs
  • Staking of DFI for passive rewards
  • Lending and borrowing with on-chain collateral
  • Tokenized assets called dTokens that mirror real-world prices

These features make DeFiChain a one-stop platform for beginner DeFi users.

What is the native token of DeFiChain (DFI)?

The native cryptocurrency of DeFiChain is called DFI. DFI is used for transaction fees, staking, governance, and as collateral within the DeFi ecosystem. In the DeFiChain DEX, DFI acts as the base trading pair, allowing users to buy and sell dTokens against DFI.

You can also earn DFI through staking and liquidity mining, making it both a utility and reward token.

How to buy DeFiChain (DFI) tokens?

You can buy DFI tokens from major centralized exchanges that list DFI, such as KuCoin and Bittrex, or directly on the DeFiChain DEX. After purchasing, you should transfer DFI to your own DeFiChain wallet or a compatible hardware wallet for safe storage. The official DeFiChain Wallet supports DFI and dTokens, and it is available for mobile and desktop.

Remember to keep your recovery phrase secure and use a non-custodial wallet whenever possible.

What are the pros and cons of DeFiChain?

DeFiChain offers several advantages for beginners: low transaction fees, fast settlement, Bitcoin-anchored security, and a simple interface. However, it also has some downsides, including a smaller ecosystem compared to Ethereum, potential price volatility of DFI, and reliance on a limited number of masternodes.

  • Pros: low fees, user-friendly, built-in DeFi modules
  • Cons: less developer activity, DFI volatility, smaller community

Overall, DeFiChain is a solid choice for basic DeFi operations, but not ideal for complex custom dApps.

DeFiChain vs Ethereum: which is better for DeFi?

DeFiChain is better for beginners who want simple, low-cost DeFi services like trading and lending, while Ethereum is better for developers and users who need a broad, flexible smart-contract ecosystem. DeFiChain specializes in DeFi only, offering predictable fees and built-in functionality. Ethereum, on the other hand, has many more dApps, protocols, and developers, but often charges higher gas fees.

If your goal is to stake, lend, or trade tokens with minimal friction, DeFiChain may be more suitable. If you want to explore thousands of decentralized applications, Ethereum remains the leader.

Is DeFiChain safe and secure?

DeFiChain is designed with a hybrid security model: it combines its own Proof-of-Stake network with Bitcoin's proof-of-work via a process called 'anchor.' This means the network's history is repeatedly recorded onto Bitcoin's blockchain, making it very difficult to alter. That said, no blockchain is risk-free, and users must follow best practices for wallet security and private key management.

Because DeFiChain uses a fixed set of audited modules rather than arbitrary smart contracts, the attack surface is reduced, but you should still research any new dToken or pool before participating.

Final Thoughts

DeFiChain offers an accessible entry point into decentralized finance, especially for crypto beginners. Its focus on simple, low-cost DeFi services makes it a practical alternative to Ethereum, and its Bitcoin anchoring provides an extra layer of security. However, it is still a relatively young platform with a smaller ecosystem.

If you are new to crypto, start with the official DeFiChain wallet, try a small trade on the DEX, and explore staking or lending. Always use secure storage and never invest more than you can afford to lose. Whether DeFiChain is right for you depends on your specific needs and risk tolerance.
