“…There are components including consensus, network structure, transaction, signature, hashing, and data placement in a blockchain, and the choice of each component affects the design and performance of that network. Consensus algorithm (Garay & Kiayias, 2020) is used to choose the person creating a block when it is added to a blockchain. The most popular consensus is proof-of-work used in Bitcoin and Ethereum.…”

Anti-forgery information, transaction verification, and smart contract are functionalities of blockchain technology that can change the traditional business processes of IT applications. These functionalities increase the data transparency, and trust of users in the new application models, thus resolving many different social problems today. In this work, we take all the advantages of this technology to build a blockchain-based authentication system (called the Vietnamese Educational Certification blockchain, which stands for VECefblock) to deal with the delimitation of fake certificate issues in Vietnam. In this direction, firstly, we categorize and analyze blockchain research and application trends to make out our contributions in this domain. Our motivating factor is to curb fake certificates in Vietnam by applying the suitability of blockchain technology to the problem domain. This study proposed some blockchain-based application development principles in order to build a step by step VECefblock with the following procedures: designing overall architecture along with business processes, data mapping structure and implementing the decentralized application that can meet the specific Vietnamese requirements. To test system functionalities, we used Hyperledger Fabric as a blockchain platform that is deployed on the Amazon EC2 cloud. Through performance evaluations, we proved the operability of VECefblock in the practical deployment environment. This experiment also shows the feasibility of our proposal, thus promoting the application of blockchain technology to deal with social problems in general as well as certificate management in Vietnam.

“…Proof of work (demonstrating ownership of computing resources) and proof of stake (staking digital assets owned on the blockchain system) are two common methods. 2,5 3 Consortium governance (i.e., permissioned blockchain systems). Participation in the consensus protocol is limited to miners approved on a whitelist defined at system initialization.…”

“…This sidesteps the wasteful resource expenditure of Sybilresistant protocols such as proof of work. 2,5 For each type of governance, there is a need to reward correct participant behavior. The first type of incentive is intrinsic-i.e., miners maintain the system faithfully because they derive value from using it.…”

I n 2008, an author using the pseudonym Satoshi Nakamoto wrote a white paper describing Bitcoin, a new decentralized cryptocurrency. 8 Unlike past attempts at forming a cryptocurrency-attempts that relied on preestablished trusted entities for the system to operate correctly-Bitcoin's design runs on the open Internet, with no one in charge, while maintaining tight security. While the building blocks of Bitcoin were not novel, the composition of these properties into a single system was a meaningful contribution, 9 and Bitcoin became the first cryptocurrency to achieve widespread attention.
