The cryptocurrency world cannot exist without stablecoins, just like the West cannot exist without Jerusalem.

Stablecoins are a bridge between traditional finance and the crypto world, providing a stable value storage and transaction medium for the cryptocurrency market with volatile prices. Whether it is cross-border payments, smart contract transactions, or the operation of DeFi projects, stablecoins are playing an irreplaceable role and have become an indispensable part of the currency circle. According to the latest data from Coin Metrics Network Data Pro, the total supply of stablecoins worldwide is close to $161 billion, a figure that is once again close to the historical high. According to data released by HashKey Group, an overseas cryptocurrency trading agency, quarterly stablecoin transfers have increased seventeen times over the past four years, from $17.4 billion in the second quarter to $4 trillion. On July 17, 2024 alone, the total transaction volume of the entire global stablecoin market reached $87 billion, accounting for 91.7% of the total transaction volume of the entire cryptocurrency market, of which the largest transaction volume stablecoin was USDT, reaching 83.3%.

However, what is overlooked by many cryptocurrency users is that stablecoins such as USDT, which we commonly use, are all issued by centralized institutions and heavily rely on the daily management and operation of the centralized institutions. This is essentially no different from traditional bank printing and issuing of coins. Although decentralized stablecoins (such as DAI) were once the "hope of the whole village" in this field, MakerDAO recently upgraded to Sky Protocol, launched a new stablecoin USDS, and introduced a freezing function. This information has once again sparked debate about the ownership and decentralization of stablecoins, and even disillusionment with decentralized stablecoins.

Disillusionment with decentralized stablecoins?

MakerDAO was once a symbol of the decentralized ideal in the DeFi field. Its DAI is a stablecoin that is not controlled by a central authority. However, with the launch of USDS, this ideal seems to be challenged.

It is reported that USDS may introduce a freezing function similar to the centralized stablecoins USDT and USDC. Under certain circumstances, the issuer of USDS or the relevant governance entity can freeze the user's funds, which is obviously "contrary" to the original intention of decentralization.

In the traditional financial system, banks and governments have the power to freeze accounts, usually to combat crime or respond to emergencies. However, when this freezing function is introduced into stablecoins, it will make stablecoin holders have to face an uncertain future - their funds may be locked on the chain by a centralized institution far away at any time.

With the popularization of blockchain technology, governments around the world are increasingly tightening their supervision of crypto assets. For example, USDT (Tether), as the world's largest and most widely used stablecoin, is often seen on the Internet in news that it cooperates with regulators to freeze or seize USDT assets in certain specific wallet addresses. For example, in 2023, Tether froze millions of dollars worth of USDT, which were related to certain criminal activities. In an official statement, Tether clearly stated: "We work with global regulators and law enforcement agencies where appropriate to combat and prevent criminal activity." The technical principle of this function is based on the control authority of smart contracts. Tether reserves the "blacklist" function authority for the USDT contract, which can add certain addresses to the blacklist and prevent the USDT in these addresses from being transferred or redeemed.

The designers of USDS claim that the freezing function is to prevent risks and ensure compliance. But this also raises a fundamental question: if a decentralized stablecoin can be controlled remotely, and this centralized control requires users to rely on the goodwill and compliance of the issuer to some extent, rather than fully controlling their own assets.

So, what is the difference between it and the centralized currency in the traditional financial system?

Does DeFi still have a future?

The brand upgrade of MakerDAO has caused some concern among the DeFi community. After all, the core concept of DeFi has always been to provide users with a free and open financial system by using smart contracts and blockchain technology to provide financial services without intermediaries. However, the freezing function of USDS and similar compliance measures have, to some extent, broken this ideal and cast a shadow on the future of DeFi.

First of all, this incident shows that under the regulatory pressure of the real world, decentralized financial projects have to make compromises. Although the original intention of decentralization is to reduce dependence on traditional financial intermediaries, with the mainstreaming of crypto assets, the regulatory requirements of governments have become increasingly stringent. In order to survive within the regulatory framework, DeFi projects may have to find a balance between decentralization and compliance. In the future, more projects may take similar measures for compliance, causing the DeFi field to gradually evolve into a "pseudo-decentralized" market dominated by a few large companies, thereby losing its original innovative vitality and inclusiveness, and even losing the original meaning of DeFi.

Secondly, USDS’s freezing function and compliance compromise may lead to further divisions in the DeFi community. Some users may accept such compromises, believing that this is the only way for DeFi to go mainstream and achieve large-scale adoption; while other users may believe that this is a betrayal of the decentralized ideal and choose to turn to more decentralized projects or even abandon DeFi altogether. In this way, the DeFi ecosystem may become more complex and diversified, but also more susceptible to division and internal friction.

Finally, in the long run, this incident may prompt deeper innovation and change in the DeFi field. On the one hand, project parties may explore new technical solutions that can meet compliance requirements while maintaining decentralized properties as much as possible; on the other hand, users may pay more attention to truly decentralized projects, pushing this field towards a more purely decentralized direction. In any case, whether DeFi still has a future depends on how the industry responds to this crisis and finds a new balance between compliance and decentralization.

As a practitioner in the Web3 industry, Honglin's simple view is that if mainstream DeFi projects want to meet the increasingly stringent global regulatory requirements, they will inevitably introduce centralized mechanisms such as USDS with remote freezing functions. Although this design can meet the requirements of regulatory authorities, it is somewhat contrary to the original intention of the birth of Bitcoin. Perhaps future crypto assets will continue to compete with each other. If you are pragmatic and compromise, you can hold compliant crypto assets. If you really want to control your own crypto assets, perhaps Bitcoin (BTC) is a better choice.
