Blockchains as a means to promote privacy protecting, access availing, incentive increasing, ELSI lessening DNA databases

Frontiers in Digital Health, 2023
Not all blockchains are created equal, and many cannot accommodate all of the primary characteristics of big data: Variety, Velocity, Volume and Veracity. Currently, public blockchains are slow and clunky, it can be expensive to keep up with the velocity

Traceability in Permissioned Blockchain [PDF]

2019 IEEE International Conference on Blockchain (Blockchain), 2019
In this paper, we have achieved privacy protection and high transparency in a permissioned blockchain. There is a sidechain that connects the permissionless blockchain and the permissioned blockchain. The behavior in the permissioned blockchain is almost a black box from the perspective of the permissionless blockchain.

An experimental evaluation of the scalability of permissioned blockchains [PDF]

2021 8th International Conference on Future Internet of Things and Cloud (FiCloud), 2021
Permissioned blockchains are decentralized digital systems, which are used to record transactions and which maintain multiple, synchronized copies of the whole list of transactions (i.e., the ledger) on geographically dispersed nodes. Cryptographic operations are used to 'chain' transactions in the ledger, making the system tamper-resistant.
