Despite their utility, blockchain wallets present significant challenges, such as reliance on trusted third parties, vulnerability to adversaries observing and potentially linking user interactions, key recovery issues, and synchronization of cryptographic keys across multiple devices. This paper addresses these challenges by introducing a fully decentralized multi-platform wallet that leverages blockchain and InterPlanetary File System (IPFS) technologies for managing asymmetric keys and enabling key recovery. This novel approach empowers users to interact with dApps built on blockchain smart contracts while preserving their privacy and ensuring seamless key recovery in the case of device theft or damage.

To address these concerns, we apply the Design Science Research (DSR) methodology to propose and develop a functional blockchain-based healthcare information exchange system.

The efficacy and complementarity of the solution are evaluated based on a combination of scenario-based simulation and logically informed arguments. The integration of permissioned blockchain technology and interactive ontology mapping techniques in our proposed solution provides secure, reliable, and trustworthy data exchange among healthcare institutions.

In addition, ATBFT has an automatic switching mechanism between leaderBFT consensus and leaderlessBFT consensus.

Furthermore, it can guarantee the execution of the entire consensus process to ensure that the tx<span><span><sup>2</sup></span></span>-transactions are uninterrupted.
