Abstract
The Notarial Office(NO), working on providing various essential certificates, still relies on manual handling and requires paper materials from other government departments. That brings lots of inconvenience. The Notarial Office rejects non-local paper materials for their lower credibility in the local place and then cannot provide cross-borders services. It also easily cause sensitive information leakage as copies of paper materials have been stored. In this case, a blockchain-based system is suitable to address challenges in this scenario because of its advantages (e.g, decentralized, immutability, transparency, auditability). We implemented this system on top of the Hyperledger Fabric. Moreover, we replace manual operations with smart contracts, set extra ledgers to off-load different types of transactions and provide encryption for private information when needed. In the end, we get an expected result. That is, the modification outperformed the unmodified network in experiments.
Highlights
Government certificate plays an important role in the daily life of citizens in many countries
Since that the Notarial Office (NO) still relies on persons to handle materials and provide services, there is no need to consider the cost of transition between the two different systems, namely distributed system and centralized system, if the blockchain-based system is directly implemented to improve work efficiency
We propose a decentralized system based on blockchain to meet the demands of the Notarial Office and conduct a series of experiments to investigate the performance and feasibility of this system
Summary
Government certificate plays an important role in the daily life of citizens in many countries. Since that the NO still relies on persons to handle materials and provide services, there is no need to consider the cost of transition between the two different systems, namely distributed system and centralized system, if the blockchain-based system is directly implemented to improve work efficiency. This article demonstrates the feasibility and effectiveness of implementing a blockchain-based system to improve the quality of NO services and provides experimental data to reference This system, which is built on top of the Hyperledger Fabric, has two types of ledgers according to the destination of transactions, given that the distance of different cities in a large country may cause a big delay and low TPS (Transactions per second).
