“…The adoption of blockchain technology can help build a certification infrastructure that enables students to control the complete record of their achievements. Thus, it would help the students to have full access to their awards and certificates even in the case where the issuing institute no longer exists [36]. Furthermore, students can share their credentials with other universities and prospective employers while being assured that they will be sharing this information with trusted parties only [35].…”

Due to the growing interest in distributed ledger technologies such as blockchain, researchers in different areas, including the higher education sector, are investigating possibilities surrounding blockchain adoption. Despite this, no guiding framework has been developed for the application of blockchain and related technologies in the use of certificating systems that issue sharable and authentic student credentials. Existing certificating systems are marked by their lack of speed and low reliability and, in certain education systems, they produce social and cultural conflicts. Therefore, this paper offers an analysis of blockchain adoption in this field, focusing especially on the process of producing and sharing higher education certificates. The paper describes the second phase of an ongoing research project by presenting a certificate validation and sharing framework that guarantees authenticity through leveraging the privacy and security features of a blockchain network. The framework also covers the architectural design of a blockchain-based certificating system to solve problems and offer solutions in the context of higher education. Two groups of participants are also included in an empirical study focusing on an evaluation of the proposed framework in relation to its ability to describe and explain blockchain adoption in higher education. The validity and reliability of the framework is tested using a sequential mixed methods design involving the collection of quantitative survey data. It is expected that the proposed framework will have useful applications in different fields where it is necessary to determine whether a satisfactory level of blockchain technology has been maintained in accordance with relevant privacy and security standards. Finally, this study is about attitudes towards the technology and theory of acceptance by users, students and prospective employers, rather than a technological development study.

“…Bluzelle is a project born in 2017 described in its whitepaper as the "Decentralized Database for the future". As known, the blockchain stores hashed data of transactions, and if documents are signed or registered with blockchain, "only" the hash is uploaded on the chain [133]. This is to limit the size of the blockchain, which is replicated in every node.…”

Decentralized Finance (DeFi) takes the promise of blockchain a step further and aims to transform traditional financial products into trustless and transparent protocols that run without involving intermediaries. Similar to how 2017 was the year of ICOs, 2020 was the year of DeFi, with more than fifteen billion dollars of total investments. The decentralized platforms utilize oracles to retrieve asset data from the external world, but their choice and management criteria are often unknown to the end-users. If oracles are poorly selected or managed, the funds of a rising number of investors are inevitably in danger. The issue, known as “the oracle problem”, which makes real-world applications controversial and debated due to the loss of decentralization, had recently drawn attention to DeFi, given the crescent number of related hacks that caused the loss of millions of dollars held in DeFi projects. Through a multivocal approach that considers academic papers, whitepapers, preprints, and opinion posts, this study aims to shed light on the pattern that identifies the oracle problem in DeFi and outline the most promising ways to overcome the related weaknesses. This research supports the view that the oracle problem in decentralized finance bears specific characteristics which require standardization and appropriate economic incentives to be addressed.

Decentralized Finance (DeFi) takes the promise of blockchain a step further and aims to transform traditional financial products into trustless and transparent protocols that run without involving intermediaries. Similar to how 2017 was the year of ICOs, 2020 was the year of DeFI with more than $15 billion of total investments. The decentralized platforms utilize oracles to retrieve asset data from the external world, but their choice and management criteria are often unknown to the end-users. If oracles are poorly selected or managed, the funds of a rising number of investors are inevitably in danger. The issue known as “the oracle problem,” which makes real-world applications controversial and debated due to the loss of decentralization, had recently drawn attention to DeFi given the crescent number of related hacks that caused the loss of millions of dollars held in DeFi projects. With a multivocal approach, this paper aims to shed light on the pattern that identifies the oracle problem in DeFi and outline the most promising ways to overcome the related weaknesses.
