Permissionless and permissioned blockchain diffusion
International Journal of Information Management, 2020Abstract This paper explores the barriers and drivers of diffusion associated with permissionless and permissioned blockchains, seeking to establish whether they are the same or different and whether barriers and drivers change over time. The study was undertaken in two stages: (i) interviews in 2016 that examine the barriers and drivers of diffusion;

Economics of Permissioned Blockchain Adoption
SSRN Electronic Journal, 2020We construct an economic framework for understanding the incentives of the participants of a permissioned blockchain for supply chains and other related industries. Our study aims to determine whether adoption of blockchain is socially beneficial and whether such adoption arises in equilibrium. We find that blockchain reduces information asymmetry for

On Sharding Permissioned Blockchains
2019 IEEE International Conference on Blockchain (Blockchain), 2019Permissioned Blockchain systems rely mainly on Byzantine fault-tolerant protocols to establish consensus on the order of transactions. While Byzantine fault-tolerant protocols mostly guarantee consistency (safety) in an asynchronous network using 3f+1 machines to overcome the simultaneous malicious failure of any f nodes, in many systems, e.g ...

Hardening Permissioned Blockchains with Verifiable Randomness
2020 IEEE International Conference on Blockchain and Cryptocurrency (ICBC), 2020Permissioned blockchains are networks with identifiable participants. A prominent example is Hyperledger Fabric, that introduces the execute-order-validate architecture. The execution phase enables defining application level trust assumption by setting an endorsement policy, namely a set of rules that define the peers (affiliated with organizations ...

A Reliable Storage Partition for Permissioned Blockchain
IEEE Transactions on Knowledge and Data Engineering, 2021The full-replication data storage mechanism, as commonly utilized in existing blockchains, is the barrier to the system's scalability, since it retains a copy of entire blockchain at each node so that the overall storage consumption per block is $O(n)$ O ( n ) with $n$ n participants. Yet another drawback is that this mechanism

A Fast Consensus for Permissioned Wireless Blockchains
IEEE Internet of Things Journal, 2023With the wide deployment of Internet-of-Things (IoT), blockchain systems have been playing a crucial role to establish a trusted computing environment among potentially mistrusting agents without depending on a centralized server. Different from previous blockchain consensus protocols adopted in IoT, which rely on efficient and stable transmissions, in

An Auditable and Secure Model for Permissioned Blockchain
Proceedings of the 2019 International Electronics Communication Conference, 2019The intrinsic tamper-resistant characteristic of blockchain enables transaction to be permanently stored as immutable record, which provides extremely reliable information traceability for some application scenarios such as supply chain and copyright protection.
