Towards roadmap to implement blockchain in healthcare systems based on a maturity model

Journal of Software: Evolution and Process, Volume 34, Issue 12, December 2022., 2022
This study presents a roadmap to develop a maturity model for blockchain in healthcare (MMBH) based on critical barriers (CBs), critical success factors (CSFs), and the best practices for blockchain implementation in healthcare systems. As a first step to develop the MMBH, in this paper, we present the initial results of a systematic literature review (

Securing Financial Transactions with a Robust Algorithm: Preventing Double-Spending Attacks

Computers, 2023
A zero-confirmation transaction is a transaction that has not yet been confirmed on the blockchain and is not yet part of the blockchain. The network propagates zero-confirmation transactions quickly, but they are not secured against double-spending ...

Homomorphic Hashing Based on Elliptic Curve Cryptography [PDF]

, 2023
For avoiding the exposure of plaintexts in cloud environments, some homomorphic hashing algorithms have been proposed to generate the hash value of each plaintext, and cloud environments only store the hash values and calculate the hash values for future needs.
