Why Decentralized Exchanges are the Future of Trading?
Cryptocurrencies and blockchain-based technologies are blooming. Transaction volume has reached $10B per day, market capitalizations are through the roof, and user adoption has reached a truly global scale. Blockchain’s increasing utility in diverse use cases is moving the world closer to a trustless economy, thus removing the need for third parties to exchange goods and services.
Paradoxically, more than 95% of all cryptocurrency transactions pass through absolutely centralized exchanges on platforms such as Coinbase, GDAX, Binance, and Bittrex. That’s right, decentralized assets are being stored and traded on centralized platforms which operate as escrows for their clients and do not record transactions on the blockchain. This has led to massive breaches of security and the unsafe handling of funds, private keys, and personal data. In 2018 alone, more than ~$730M in cryptocurrency has been stolen by hackers.
Trading cryptocurrencies is a risky business, but there is no reason that traders should face risks other than those they are already willing to take. The blockchain community knows this problem, and several entrepreneurs are taking it upon themselves to create what they believe will be the future of trading: Decentralized Exchanges. The central idea here is that traders should remain custodians of their funds.
Before diving in, some definitions:
Centralized Exchanges (CEX): A centralized exchange is a third party platform that matches 2 entities, such as individuals or institutions, looking to transact or exchange with each other. Centralized exchanges enforce KYC and AML verifications and facilitate fiat on/off-ramps. These platforms also store much of their customers’ personal information, account balances, portfolio allocations, and fund positions.
Decentralized Exchanges (DEX): A decentralized exchange is not coordinated by any one central entity or owner. Instead, it runs on a distributed ledger, like cryptocurrencies themselves. By definition, decentralized exchanges do not facilitate fiat on/off-ramps. Additionally, unlike central exchanges, these platforms do not hold their customers’ personal information, account balances, portfolio allocations, and fund positions.
The benefits of decentralized exchanges vs centralized.
1. No single point of failure: Centralized exchanges generate significant trade volume through the millions of customer funds and accounts that utilize the platform. These exchanges serve as legal custodians responsible for the billions of trades per day, all of which are maintained on traditional servers. By allowing customers to log in with an email and password, centralized exchanges become a hugely attractive target for hackers and bad actors. Decentralized exchanges, on the other hand, run on a distributed ledger and therefore do not face the same risks of exploitation. Also, because they do not hold the funds and the private keys of their entrusted users, decentralized exchanges keep their users’ funds and personal data secure without undermining their privacy rights.
2. No single point of control: One of the main reasons why cryptocurrencies appeal to such a massive, global audience is because they can operate outside the reach of any one government, regulator or central authority. While this clearly raises questions on best practices to monitor criminal activity of funds, it also means that individuals can escape corrupt government regimes that have the ability to improperly seize privately owned assets. In a truly decentralized exchange, there is no way for any one person or entity to “take control” of the system, making it much more resistant to censorship, government interference, and power games.
So why isn’t everyone using decentralized exchanges?
While decentralized exchanges offer tremendous benefits in their anonymity, security, and freedom from censorship, there are multiple practical challenges that must be overcome become they can compete with the existing centralized exchanges:
1. Usability: The relatively difficult or poor (in comparison to Coinbase) user interface and user experience of DEX platforms drastically restricts their reach.
2. Functionality: Decentralized exchanges are still well behind centralized exchanges in terms of functionality, including shortcomings in order type (no stop loss or limit order available). They have very low trade volumes also limit the diversity of coins made available and contribute to a lack of quality coins to trade.
3. Speed: Validating each transaction on the blockchain takes longer time.
4. Interoperability: There is a need for cross-chain exchanges and more decentralized platforms to interact with one another.
5. Liquidity: Traders do not join decentralized exchanges because few other traders are on the marketplace to be the counterparty for their trade, which leads to a low transaction volume and the classic chicken and egg problem.
