Cryptocurrency : bridging the gap between sovereignty and performance






In 2019, an estimated 99% of crypto asset transfers have been carried out on centralized exchanges (CEX), primarily based on the quantity utilized by prime crypto critic Nouriel Roubini. CEXs are prone to stay a central aspect of the crypto buying and selling panorama for the foreseeable future. CEXs are quick and handy, however typically require retailers to fund an account managed by the alternate. Sadly, historical past illustrates that this lack of sovereignty over a person’s digital belongings could be an excessive and pricey compromise.

Decentralized exchanges (DEX) supply an intriguing various and are gaining momentum, however they aren’t prepared for prime time but. Due to this fact, there should be a approach to bridge the gap between person sovereignty and alternate performance.

On the subject of custody, management is healthier than belief

The nightmare situation for retailers utilizing CEX is that they might fall sufferer to hacking or fraud and lose their deposited funds. Though seven years have handed since the collapse of Mt. Gox in 2014, his title remains to be synonymous with the risks of cryptocurrency fraud. As soon as the world’s largest Bitcoin (BTC) alternate, it filed for chapter in 2014 after Bitcoin of roughly 650,000 shoppers disappeared. Victims are nonetheless looking for partial compensation from the insolvency proceedings in 2021.

Sadly, this type of counterparty danger stays a menace to this present day. In April, the founding father of Turkish inventory alternate Thodex ran away with $ 2 billion in belongings from unaccounted for traders. A yr earlier than that, China’s FCoin and Australia’s ACX closed with out warning. Whether or not these failures have been because of fraud, a hack, or enterprise mannequin points, it doesn’t matter a lot to out-of-pocket traders. In a perfect world, the alternate operator (or a hacker who has compromised an alternate) ought to be denied the means to discretely transfer consumer funds between accounts.

The established order: managing danger carries increased prices

For well-capitalized or well-connected retailers, there are methods to mitigate these dangers, however the options have their very own drawbacks.

Credit score is a approach to keep away from having to pre-finance an account. Sure, that’s attainable if you’re prepared to pay excessive charges to a dealer or if you will get a line of credit score with a specific alternate by establishing your self as a number one buyer. Both method, it’s costly (and in the latter case, gradual), and solely prime spenders have any probability of growing such a superb relationship with a number of exchanges.

Off-exchange settlement networks supply a substitute for loading funds straight onto exchanges. These intermediaries maintain the service provider’s funds and assume the counterparty danger for every alternate. In right now’s setting, these intermediaries present a helpful service for establishments, however nonetheless symbolize a further layer of expense. Frictionless buying and selling is over.

DeFi and the downside of transparency

If the downside is lack of asset sovereignty in CEXs, might DEXs be the resolution? Sure and no. Through the use of sensible contracts and decentralized liquidity swimming pools to allow asset exchanges, DEXs get rid of middlemen and permit merchants to retain sovereignty over their belongings. Nevertheless, DEXs additionally include large compromises, particularly for giant merchants.

In a DEX, as an alternative of matching consumers and sellers by a centralized matching engine, a wise contract performs the trades. Contributors known as “yield farmers” can lock their belongings in a liquidity pool and earn returns in return. Every pool of liquidity makes it simple to commerce a specific asset pair, like Bitcoin and Tether (USDT), for instance. The sensible contract will modify returns in accordance with the relative quantity of belongings in the group, to draw extra scarcer belongings and preserve a wholesome stability. At the similar time, the transaction charge a service provider pays will fluctuate relying on the relative shortage of the belongings concerned.

Though modern, this strategy doesn’t scale effectively. Relying on the dimension of the liquidity pool, massive trades can have a right away robust impact on buying and selling charges. Additionally, DEXs are very vulnerable to pioneering. The leaders are merchants (usually bots) who scan for data suggesting a giant commerce is coming, then leap in with their very own commerce to revenue from the anticipated value motion. After all, these working operations have their very own impact on the market value, lowering the revenue of the initially deliberate transaction. In CEXs, the danger is that if pre-financing is completed on-chain, third events can infer {that a} large commerce is about to happen. Nevertheless, these dangers are enormously elevated when utilizing a DEX.

As a consequence of the community delay in processing transactions, pending transactions can flow into between validating nodes earlier than they’re lastly dedicated to a block. Actually, in sensible contract-based DEXs, bids are despatched transparently, so a frontrunner merely has to look at incoming bids and bid on their very own with increased charges or much less community lag to make a revenue. Additionally, as validators resolve the order of transactions for the blocks they produce, it might introduce one other manipulation alternative.

So whereas DEXs are a tempting thought and current the alternative for passive return, they’re at the moment not effectively suited to the wants of most merchants.

Can we construct a greater DEX?

So can the pursuits of merchants be higher protected with out the downsides of present DEXs?

One attainable strategy right here could be to make use of blockchain as a trusted supply and mix it with off-chain confidential computing {hardware} to deal with order matching. For instance, Trusted Execution Environments (TEEs) can set up an remoted space inside a pc processor, operating individually from the commonplace working system that’s not accessible to the system administrator.

The comparability engine and commerce execution software program for an alternate might be positioned inside a TEE, eradicating it from the management of the alternate proprietor. Every dealer might then decide an allocation that the TEE might spend to settle trades on their behalf, eliminating the want for pre-financing or intermediaries. As well as, since the match would happen off-chain, the danger of overtaking would even be lowered.

Pondering long run, a mixture of different rising methods, akin to multiparty computing or zero-knowledge testing, might be used to realize related outcomes, however these approaches are at the moment much less mature and could be tough to implement in real-world eventualities. .


The necessity to pre-finance on cryptocurrency exchanges presents issues and dangers that symbolize a big barrier to the adoption of digital belongings. Whereas DEXs supply an modern various that leaves the dealer in command of their funds, in addition they include important trade-offs. To drive widespread adoption of digital belongings and acquire a aggressive benefit, cryptocurrency exchanges should discover methods to protect person sovereignty with out compromising performance.
