Researchers at the Universities of Waterloo, Ontario and Concordia, Quebec, have developed Lelantos, a blockchain-based home delivery service and Thor-based onion routing techniques
Onion routing is a technique for anonymous communication over a computer network. In an onion network, the messages are encapsulated in encryption layers, similar to the layers of an onion. The encrypted data is transmitted by a series of network nodes called onion routers, each of which “removes” a single layer, uncovering the next destination of the data. When the final layer is decrypted, the message arrives at its destination. The sender remains anonymous because each intermediary knows only the location immediately preceding and following nodes.
The aim of this project is: “to offer customers anonymity, a fair exchange and not be able to connect the merchant to the customer”.
That is, the classical merchant / customer relationship would not be observable by an outside eye.
The Blockchain platform Lelantos uses smart contracts to facilitate deliveries in a direct way between the delivery companies, sellers and buyers.
Thus, during a sale, a smart contract is created by the buyer wanting to receive an anonymous product from the seller, then another smart contract is then set up with the delivery company, automating the process with the Blockchain network Lelantos.
The two major advantages of this platform are security and anonymity for the seller and the buyer.
Thus, with the use of onion routing techniques, all deliveries are processed autonomously and anonymously (the delivery company does not know what product it delivers). And because of the systemic peculiarities of the blockchain, data changes are not allowed, thus guaranteeing the security of the transaction.
Like all Blockchain networks, it is likely that Lelantos will have to fight against the problems of congestion of its network if the traffic intensifies greatly.
Of course, government structures will definitely criticize a delivery system where no control over the goods sold is possible, especially as in countries such as the United States, the United Kingdom and Hong Kong.
However, privacy is important for more and more people in this society where everything can be traced, archived and analyzed. Moreover, this anonymity could serve as a “shield” against some ill-intentioned people using blockchain transparency to carry out reprehensible actions (for example, the transparency of the Bitcoin network allows hackers to target well-filled portfolios).
