How does a decentralized exchange implement fiat currency transactions?

Decentralized exchanges are decentralized digital currency trading platforms that operate differently from traditional centralized exchanges. They do not rely on any centralized institution or authority to conduct transactions, but use intelligent Contract technology implements transactions directly on the blockchain.

However, many decentralized exchanges currently only support transactions between cryptocurrencies and not fiat currencies. So, how to implement legal currency transactions on decentralized exchanges?

Difficulties in realizing fiat currency transactions on decentralized exchanges

The realization of fiat currency transactions on decentralized exchanges faces some difficulties and challenges, in the following aspects:

1. Value transmission problems

Cryptocurrency transactions have been Widely recognized, such as Bitcoin and Ethereum, etc., but the transmission of fiat currencies involves more legal and financial regulations, requiring the participation of banks or other financial institutions to ensure legality and stability.

2. Supervision of centralized institutions

In order to ensure the legality and identity verification of transactions, traditional supervision of centralized exchanges may also need to be applied to decentralized exchanges, which may undermine their decentralized nature. Nature.

3. Fiat Currency Encryption and Digital Identity Verification

Implementing fiat currency transactions requires digital identity verification and its scalability, as well as technical support for banks to manage digital assets as currency.

How to implement fiat currency trading on decentralized exchanges?

Despite the difficulties and challenges, there are still some methods to achieve fiat currency transactions in decentralized exchanges, such as:

1. P2P electronic cash system

Peer-to-peer (P2P) electronic cash system can enable Transaction parties exchange digital currency and fiat currency directly. This makes transactions faster and more secure, reducing the need for intermediary agents.

2. Stablecoin trading pair

Stablecoin is a digital currency based on a certain French currency, and its price is relatively stable (pegged to currencies with fixed exchange rates such as the US dollar, such as USDT and USDC, etc.). By using stablecoin trading pairs, users can trade fiat currencies and cryptocurrencies on decentralized exchanges to achieve fiat currency transactions.

3. Decentralized Currency Exchange Protocol (Dex)

In this case, currency exchange is carried out through smart contract programs without the need for traditional financial institutions, inter-bank transfers and other intermediary agents. With the addition of digital identity verification technology, this model can provide some assurance for fiat currency transactions.

Conclusion

Fiat currency trading on decentralized exchanges is still in its infancy, and although there are still many technical and legal difficulties, the possibilities of how to achieve decentralized currency exchange are still increasing over time.

In such a new trading economy, decentralized exchanges have the potential to subvert the traditional financial system. Decentralized currency exchange protocols, P2P electronic cash systems and stablecoin trading peer-to-peer technologies are key to achieving this goal. Only through these technical means and correct top-level design can a safe, successful and influential decentralized exchange be developed.
