Breve descrição: Blockchain, initially introduced as the backbone of the Bitcoin cryptocurrency, is now a technology for may other applications that can benefit from immutable logged transactions and dis. Abstracting the currency logic away opens Blockchain to endless applications (e.g.finance, supply chaining, healthcare or IoT). Digital signatures are a key component of the blockchain system. In this this we will study/propose how to use group signatures for HLF or TEZOS Blockchain, addressed as an enhanced mechanism for permissioned blockchains. Byzantine Fault Tolerant signatures will enhance the resilience, robustness and trust-dicentralization, while preserving the distributed Blockchain nature. In particular: (1) we will propose how to use signature schemes, (2) evaluate comparative performance, (3) discuss advantages and limitations and (4) implement a Framework hiding the implementation details, for testing and evaluating different signature schemes to enhance the current blockchain platforms
Observações: In this work, we can address possible different blockchains, from IBM HLF, TEZOS, or other open-source blockchains.
