Cache Me If You Can: Crypto Trading, Decentralized
Spot exchanges, over-the-counter/OTC trading desks, and futures contracts would likely rank amongst the most popular methods for trading cryptocurrencies between two or more parties.
Despite their popularity though, most of these trading venues utilise centralised infrastructure in at least one area of their operations.
When combined with the endemic security threats which crypto trading services regularly face: centralized fundamental functions are a considerable threat to users who value the privacy of their transactions.
“A Peer-to-Peer Electronic Cash System”
Cryptocurrency is still a burgeoning industry, with the number of ICOs and market investment having increased by several multiples even just over the past eight months when compared to the whole of 2017.
Despite this: concerning conventions have already established themselves that challenge the original vision prescribed by Satoshi Nakamoto for Bitcoin.
The enigmatic Satoshi Nakamoto became a legend upon publication of his seminal cryptocurrency white-paper entitled ‘Bitcoin: A Peer-to-Peer Electronic Cash System’ (and if you haven’t read it, you really should!).
Since then, the document has served as an conceptual blueprint which has been referenced by a great number of subsequent altcoins: evident by the widespread implementation of Bitcoin’s core mechanics. An example of this is has come to be known as cryptocurrency mining, or the ‘Proof of Work’ consensus algorithm.
P2P vs P2intermediary2P?
Peer-to-peer (P2P) denotes transactions that are made between two parties without the need for an intermediary to facilitate or authorise the trade.
Mike Orcutt, associate editor at the MIT Technology Review wrote in April 2018 that:
“The whole point of using a blockchain is to let people—in particular, people who don’t trust one another—share valuable data in a secure, tamperproof way…
“One supposed security guarantee of a blockchain system is ‘decentralization.’ If copies of the blockchain are kept on a large and widely distributed network of nodes, there’s no one weak point to attack, and it’s hard for anyone to build up enough computing power to subvert the network”
Whilst this is true for many blockchains and their associated blocks for decentralized cryptocurrencies: most middle-man’ who process trades and transaction utilise a centralised system known as an ‘order book’ upon which future transaction and trade values are calculated.
In June 2009, mere months after Nakamoto’s Bitcoin paper was released to the world, a cross-departmental team from Stanford University published a related and highly recommended investigation into the contemporary status of the order-book.
The authors state that:
“most markets are order-driven, where any market participant is free to provide liquidity by submitting a buy or sell order. Submitted orders are amalgamated by price to create a limit order book. The[re is a] rule driven execution of orders in these limit order books and [also] extensive data that is available for order driven markets.”
With a centralised order-boook; all the data pertaining to transactions: such as receiver and sender addresses, value of tokens, and dates could be all-but-publicly accessible in the case of a hack or successful unwanted intrusion.
Peer-to-Peer Trading: What Can Be Done?
One solution which we have seen numerous examples of are organisations which claim to be ‘decentralized exchanges’.
On the 9th of August 2018, for example, well-known yet controversial ex-China based cryptocurrency exchange Binance launched a pre-alpha build of their highly anticipated decentralized exchange which they call ‘DEX’.
Conversely, Binance has been subject to more than their fair share of negative press and public feedback as of late and earning trust for their future projects will be no easy feat. They have to contend with hackers, pundits, and a 5.9/10 ranking on Trustpilot.
The ‘Breeze Wallet with Breeze Privacy Protocol’ launched on the 1st August 2018, and it is a means of facilitating pure peer-to-peer, user-to-user, fully decentralized transactions. As a result, Breeze hopes to introduce centralized intermediaries to the realm of obsolescence, by way of a token-tumbling protocol called ‘TumbleBit’.
