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.

Rethinking Permissioned Blockchains [PDF]
Proceedings of the ACM Workshop on Blockchain, Cryptocurrencies and Contracts, 2017 Current blockchain platforms, especially the recent permissioned systems, have architectural limitations: smart contracts run sequentially, all node executes all smart contracts, consensus protocols are hard-coded, the trust model is static and not exible, and non-determinism in smart-contract execution poses serious problems.

Parallel Transaction Execution Models Under Permissioned Blockchains [PDF]
Jisuanji kexueMost existing permissioned blockchain systems adopt serial transaction execution methods,which cannot take advantage of the high performance of multi-core processors.This serial method will be a performance bottleneck in permissioned blockchains with ...

TimeFabric: Trusted Time for Permissioned Blockchains. [PDF]
, 2021 As the popularity of blockchains continues to rise, blockchain platforms must be enhanced to support new application needs. In this paper, we propose one such enhancement that is essential for financial applications and online marketplaces - support for time-based logic such as verifying deadlines or expiry dates and examining a time window of recent ...

Permissioned blockchains and distributed databases: A performance study
Concurrency and Computation: Practice and Experience, 2019 SummaryBlockchains are increasingly studied in the context of new applications. Permissioned blockchains promise to deal with the issue of complete removal of trust, a notion that is currently the hallmark of the developed society. Before the idea is adopted in contexts where resource efficiency and fast operation is a requirement, one could ...

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.
