| Summary: | Smart Contracts along with Blockchain bring a new set of possibilities in the security protocol development: participants gain guarantees of the correct execution of the protocol steps while Blockchain provides a secure and immutable environment to execute those protocols. In contrast, current Smart Contract solutions do not provide the necessary data privacy for the interested participants in a trade, especially when they are not mutually trustworthy, being awful in scenarios of e-goods commerce. To provide a solution for e-goods trading where the involved parties do not trust each other, this work presents a fair trade protocol using Smart Contracts, Bloom Filters, and the Ethereum platform. In general, the protocol proved to be promising for medium to high-cost trades. However, its use in small-cost scenarios must be approached with caution, as the protocol's cost execution must be taken into account. |
