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

Why 'Permissioned' and 'Private' are not Blockchains
SSRN Electronic Journal, 2019This analysis shows that permissioned and private ledgers form a subclass of Distributed Ledger Technologies (DLT), which are distinguished from the original blockchain. DLTs operate with databases known as "ledgers," copies of which are distributed among multiple nodes, but not anyone can create and validate new blocks of data in such a ledger; they ...
