“…On the other hand, even though the protocol of Hinarejos et al[60] is suitable in ensuring fairness in his use-case, his protocol will not help us to ensure fairness in ours. Hence, although, their work is showing all the expected outcomes on the comparison points, it failed to fulfill all of our goals as in their case they are using a public Blockchain which could help a malicious receiver being in an advantageous situation during the exchange.Finally, Ferrer-Gomila et al[49] exchanged the items unencrypted, which violates our goal no. 2.The overall status of their works based on the comparison points is in table 6.1.6…”

“…At the same time, the electronic exchange of information should maintain all the security and privacy criteria (according to Abbas et al [1], Non-repudiation is one). Though a significant amount of work has been done on maintaining non-repudiation i.e., fair exchange policy for electronic exchange in some areas like contract-signing protocols ( [12], [29], [98]), certified e-mail systems ( [60], [65], [118]), and e-payment schemes in electronic commerce ( [18], [49], [79], [90]), the PHR exchanges have not received sufficient attention.…”

Fair digital signature of contracts and agreements is an essential process in any electronic commerce scenario, and therefore also in data marketplaces, where the relationships and agreements among the different parties (consumers and providers) are more dynamic. In multi-party contract signing, N parties wish to sign a contract in a such a way that either all signatories obtain evidence of the signing or none obtains conflicting evidence regarding the honest signatories; the exchange must be fair. In this paper, we propose a blockchain-based multi-party contract signing protocol. This solution does not require the existence or potential intervention of a trusted third party (TTP), thus avoiding the difficulty of N signatories agreeing upon a TTP. In addition, this proposal meets the necessary requirements: fairness, timeliness, non-repudiation of origin, and non-repudiation of receipt. Furthermore, confidentiality can be easily achieved. To minimize costs associated with the use of blockchain, it should be invoked in the case of exception (analogous to optimistic solutions with a TTP) and by only one of the N signatories. However, when the use of blockchain is required, we show that its cost is within perfectly manageable margins.
