Rethinking Permissioned Blockchains
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 flexible, and non-determinism in smart-contract execution poses serious problems. Overcoming these limitations is critical for improving both functi...
متن کاملAnonymous Identities for Permissioned Blockchains
In this paper we address the issue of retaining user anonymity within a permissioned blockchain. We present the ChainAnchor architecture that adds an identity and privacy-preserving layer above the blockchain, either the private blockchain or the public Blockchain in Bitcoin. ChainAnchor adds an anonymous identity verification step such that anyone can read and verify transactions from the bloc...
متن کاملVerifiable Anonymous Identities and Access Control in Permissioned Blockchains
In this paper we address the issue of identity and access control within shared permissioned blockchains. We propose the ChainAchor system that provides anonymous but verifiable identities for entities on the blockchain. ChainAchor also provides access control to entities seeking to submit transactions to the blockchain to read/verify transactions on the the permissioned blockchain. Consensus n...
متن کاملHyperledger Fabric: A Distributed Operating System for Permissioned Blockchains
Fabric is amodular and extensible open-source system for deploying and operating permissioned blockchains and one of theHyperledger projects hosted by the Linux Foundation (www.hyperledger.org). Fabric is the first truly extensible blockchain system for running distributed applications. It supports modular consensus protocols, which allows the system to be tailored to particular use cases and t...
متن کاملUnpacking Blockchains
The Bitcoin digital currency appeared in 2009. Since this time, researchers and practitioners have looked “under the hood” of the open source Bitcoin currency, and discovered that Bitcoin’s “Blockchain” software architecture is useful for non-monetary purposes too. By coalescing the research and practice on Blockchains, this work begins to unpack Blockchains as a general phenomenon, therein, ar...
