Bridging the gap between sovereignty and performance

Again in 2019, an estimated 99% of crypto-asset transfers occurred on centralized exchanges (CEXs), based on the quantity that was used by main crypto critic Nouriel Roubini. CEXs are prone to stay a central fixture of the crypto buying and selling panorama for the foreseeable future. CEXs are quick and handy, however sometimes require merchants to deposit funds in an account managed by the trade. Sadly, historical past illustrates that this lack of sovereignty over a consumer’s digital belongings may be an excessive and dear compromise. 

Decentralized exchanges (DEXs) provide an intriguing alternative and are gaining momentum, however are nonetheless not but prepared for prime time. Subsequently, there have to be a solution to bridge the hole between consumer sovereignty and trade efficiency.

With regards to custody, management is best than belief

The nightmare situation for merchants utilizing CEXs is that they may fall sufferer to hacking or fraud and lose their deposited funds. Though seven years have handed because the collapse of Mt. Gox in 2014, its title nonetheless stays synonymous with the hazards of cryptocurrency fraud. As soon as the world’s largest Bitcoin (BTC) trade, it filed for chapter in 2014 after Bitcoin of an estimated 650,000 clients went lacking. The victims are nonetheless trying to receive partial compensation from the insolvency course of in 2021.

Sadly, this type of counterparty threat stays a menace to today. In April, the founding father of Turkish trade Thodex absconded with $2 billion of investor assets unaccounted for. A yr earlier than that, China’s FCoin and Australia’s ACX each closed with out warning. Whether or not these failures had been on account of fraud, a hack, or issues with the enterprise mannequin, it doesn’t matter a lot to the buyers not noted of pocket. In a super world, the trade operator (or a hacker who has compromised an trade) must be denied the flexibility to maneuver shopper funds discretionarily between accounts.

The established order: Managing threat brings higher prices

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

Credit score is one solution to keep away from having to pre-fund an account. Sure, that’s doable if you’re prepared to pay excessive charges to a dealer or if you will get a credit score line with a selected trade by establishing your self as a high buyer. Both approach, it’s costly (and within the latter case, sluggish), and solely the most important of spenders stand any likelihood of growing such a superb relationship with a number of exchanges.

Off-exchange settlement networks present a substitute for loading funds immediately onto exchanges. These intermediaries maintain the dealer’s funds and tackle the counterparty threat for every trade. Within the present atmosphere, such intermediaries present a worthwhile service for establishments, however they nonetheless symbolize an added layer of expense. A lot for frictionless buying and selling.

DeFi and the difficulty with transparency

If the issue is the lack of asset sovereignty on CEXs, may DEXs be the answer? Sure and no. By utilizing good contracts and decentralized liquidity pools to allow asset swaps, DEXs take away intermediaries and allow merchants to retain sovereignty over their belongings. Nonetheless, DEXs additionally contain heavy compromises, significantly for bigger merchants.

On a DEX, as a substitute of consumers and sellers being paired by way of a centralized matching engine, a sensible contract performs the trades. Members referred to as “yield farmers” can lock their belongings right into a liquidity pool and earn yields in return. Every liquidity pool facilitates buying and selling for a selected pair of belongings, reminiscent of Bitcoin and Tether (USDT), for instance. The good contract will alter yields based on the relative quantity of belongings within the pool, as a way to entice extra of the scarcer asset and keep a wholesome stability. On the identical time, the transaction payment a dealer pays will range relying on the relative shortage of the belongings concerned.

Though modern, this method doesn’t scale properly. Relying on the scale of the liquidity pool, giant trades can instantly have a robust impact on buying and selling charges. As well as, DEXs are extremely prone to frontrunning. Frontrunners are merchants (typically bots) who scan for data that means an enormous commerce is coming, then soar in with their very own transaction to revenue from the anticipated worth transfer. After all, these exploitative trades have their very own impact available on the market worth, decreasing the revenue of the initially deliberate transaction. On CEXs, the chance is that if prefunding is performed on-chain, third events could possibly infer {that a} massive commerce is about to occur. Nonetheless, these dangers are vastly magnified when utilizing a DEX.

Because of the networking delay when processing transactions, pending transactions might flow into amongst validating nodes earlier than they’re lastly dedicated to a block. Certainly, on smart-contract-based DEXs, bids are despatched transparently, so a frontrunner merely wants to watch incoming bids and place their very own bid with larger charges or with much less networking delay as a way to revenue. Moreover, as validators determine on the order of transactions for the blocks they produce, it may introduce one other alternative for manipulation.

Thus, whereas DEXs are a tantalizing concept and current the chance to earn passive yield, they’re at present not properly 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 doable method right here can be to make use of blockchain because the supply of belief 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, working individually from the usual working system that’s not accessible to the system admin.

The matching engine and commerce execution software program for an trade could possibly be positioned inside a TEE, eradicating it from the management of the trade proprietor. Every dealer may then decide an allowance that the TEE may spend to settle trades on their behalf, eliminating the necessity for prefunding or intermediaries. As well as, as matching can be carried out off-chain, the chance of frontrunning would even be diminished.

Considering extra long run, a mixture of different rising methods reminiscent of multi-party computation or zero-knowledge proofs may have the ability to be used to realize related outcomes, however these approaches are at present much less mature and can be tough to implement in actual world eventualities.

Conclusion

The necessity for prefunding on cryptocurrency exchanges introduces issues and dangers that pose a big barrier to the adoption of digital belongings. Whereas DEXs provide an modern different that leaves the dealer accountable for their funds, in addition they entail important trade-offs. To drive the mainstream adoption of digital belongings and achieve a aggressive benefit, cryptocurrency exchanges have to discover methods to protect consumer sovereignty with out compromising on efficiency.
