Abstract

In recent years, the volume of data generated by IoT devices has increased dramatically. Using this data can improve decision-

making in the public and private sectors and increase productivity. Many attempts have been made to enhance and adapt

businesses to exploit this IoT data. Among these, IoT data trading is the most popular approach. To this end, ongoing projects

are currently focused on developing decentralized data marketplaces for IoT using blockchain and cryptocurrencies. Here we

explore how a decentralized data marketplace could be created using IOTA tangle and IOTA smart contract chains (SC chains).

We also consider the advantages of such architecture in terms of cost, scalability, and privacy over current designs and introduce

the various elements it should have.

I. INTRODUCTION

Internet of Things (IoT) envisions connecting billions of devices and sensors to the Internet. In recent years, the

number of devices in IoT has grown at a steady pace. As a result, the amount of data generated by these devices has

grown exponentially. A new forecast from IDC estimates that there will be 55.9 billion connected IoT devices,

generating 79.4 ZB of data in 2025. Using this data can lead to efficient and effective resource management. For

example, in Smart Cities, we have critical issues like Waste, traffic, energy, water, education, unemployment,

health, and crime management. Using this data can lead to inform decision-making and reduce costs, eliminate

Waste, and increase productivity [1]-[3].

One practical way to use this data would be to exchange it in a decentralized data marketplace, open to

everyone, and use cryptocurrencies to pay for data. We need a secure, cheap, fast, and scalable platform to facilitate

data trades in such a marketplace without violating users' privacy. To this end, several researches have explored

such marketplaces[3]-[9].

The authors in [3,4,5,6] presented their blockchain-based platforms for data trading and proposed using the

Ethereum blockchain and its smart contracts to develop this marketplace. However, these platforms do not operate

cost-effectively, as the cost of system operations in a trade exceeds the exchanged value. In general, using Ethereum

as a blockchain platform is not economically justifiable due to its rising transaction fees. Additionally, users’

privacy is not considered in the design of these platforms. Another issue is that the throughput of their platforms is

limited by the low scalability of the Ethereum network.

The authors In [7] presented a system architecture for data sharing in smart transportation systems, in which

IOTA tangle, IPFS, and Ethereum smart contracts are used for data storage and coordinating the data sharing. But

similarly, their design is not cost-effective and scalable due to the use of Ethereum.

In [8], the authors proposed using the Lightning network to fulfill the requirement of having micro-payment and

cost-effective system operation. However, establishing and closing a payment channel in the lightning network

requires two transactions, namely funding transaction, and closing transaction in the Bitcoin network. Due to the

high transaction fee in the Bitcoin blockchain, this proposal is not cost-effective. Even if the seller and buyer use

their already-established channels, their privacy would be in danger. Generally, privacy is in contrast with

efficiency (efficient routing) in the lightning network.

In [9], the authors proposed using Ethermint (instead of the Ethereum network) and state channels to develop

the data marketplace. But they did not consider users’ privacy in their design.

In an IoT data marketplace, we have a large volume of trades, so the scalability of this market should be

considered in the designed platforms. Also, the payments in a data marketplace, trading sensor data, are micro-

payments. Hence, using public blockchains like Bitcoin and Ethereum, due to their low scalability (transaction

throughput) and high transaction fees, is not suitable for this purpose.

In this paper, we have chosen the IOTA tangle due to its feeless and scalable nature, as well as IOTA smart

contracts to implement the business logic of the marketplace in a privacy-preserving manner. We also used a

decentralized data storage platform to store and access sensor data and a decentralized certificate Authority scheme

to ensure data authenticity.

The rest of this paper is organized as follows: Section II presents the general architecture of our system. The

implementation and proposed protocol are presented in section III. The performance analysis of our platform is

discussed in section IV. Section V concludes this paper.

II. SYSTEM ARCHITECTURE

To address the shortcomings of existing data marketplaces and design a platform that meets our requirements,

multiple distributed technologies are used, Such as IOTA, decentralized data storage (IPFS), and distributed

certificate authority (see figure 1). The following introduces the entities, adversary model, requirements, and the

role of each technology in the data marketplace.

A. Platform Entities

Three types of entities take part in the platform.

1) Sellers: who wish to sell their sensor data and profit from it. They use their wallet to transact with the

marketplace.

2) Buyers: who wish to buy their required data(a specific type of sensor data) and use it to increase

productivity and efficiency in their own particular application. They use their wallet to transact with the

marketplace.

3) Brokers: trusted intermediaries who match sellers and buyers and maintain the functions of the data

marketplace, which are represented as smart contracts deployed on the brokers’ SC chain and thus are

uniquely identified by their SC address.

Buyers and sellers are users of the IOTA tangle and can act as a validator of any chain, including Sellers’ and

buyers’ SC chains. However, they cannot be a validator of the brokers’ SC chain. The brokers’ SC chain is an

exceptional chain in which the chain validators are considered trusted. These validators have their real-world

reputations, and collusion among them is highly unlikely due to fierce competition between them [11]. For example,

regulatory agencies can be a part of these validators.

B. Adversary model

All entities are not trusted except the validators of the broker's chain and certificate authority(CA). The attackers

can be either internal or external and may attempt to jeopardize the privacy of users and gain information about

them and their trades. The internal attacker (who can be either a buyer or a seller) aims to find out the identity of the

corresponding party in his or her data deals. The external attacker is a third party who wishes to gain information

about marketplace transactions and violate the users’ privacy. Since the attacker can be a buyer or seller, he or she

can be a validator of the Sellers or buyers' SC chain and thus has access to the block contents of mentioned chains.

Also, they can query validators of the brokers' SC chain or peruse the anchoring transactions [11] and access the

block contents of this chain. Still, they cannot be a validator of the brokers' chain and interfere in the brokers' SC

chain operations.
