Testing blockchains – a survey of state of the art (Part I)
Abstract: The blockchain technology is continuously extending to various domains and use cases which would benefit of the by-design features of the paradigm such as decentralization, immutability, implementation of complex business logic and processes through smart contracts. As this happens, it is important that blockchain-based applications’ testing and assessment methods be considered and developed to detect bugs and vulnerabilities. The testing of this new type of application presents specific challenges that the research in the field had to consider, as they are different from other application types, the nodes are decentralized, and the smart contracts are developed in relatively recent programming languages. Also, testing blockchains may cover different testing areas, which might refer to components or performance testing. We present a survey of the state-of-the-art of the field, highlighting the challenges in this particular type of applications, the existing solutions on different testing areas and the directions which need the attention of the testing community.

A Method for Secure Generation, Exchange and Management of a User Identity Data using a Blockchain (Part I)
In this presentation we discuss the solution presented in the European Patent no. EP3883294A1 in regards to the self-sovereign problem. The patent presents a software application based on a public distributed ledger stored on a blockchain, with several users with different attributes interacting on a unsecured network. Although the main application of the product described in the patent is a self-sovereign identity scheme that can be used by government institutions and businesses alike, it also can allow autonomous devices to prove to third parties that they are allowed to perform certain tasks.

An architectural approach for self-sovereign identity using blockchain
Self-Sovereign identity (SSI) is the last stage of the evolution of identity management into a ”layer of the Internet” and offers a fully decentralized control of identity. We present a decentralized ledger identity associated with two blockchain architectures, Hyperledger Indy and Casper, which provide reliable environments for SSI implementation. An important aspect to take into account is implication of SSI choice of architecture in a regulatory framework such as GDPR.

Blockchain Security in the context of GDPR and IoT
Leveraging Blockchain for GDPR Compliance: How to Create Secure Authentication Solutions. Blockchain technology is rapidly becoming an essential component of modern business. It is increasingly being used to address a range of challenges from data security to financial transactions. With the arrival of the European Union’s General Data Protection Regulation (GDPR), the need for secure authentication solutions is becoming more important. Leveraging blockchain technology to create GDPR compliant authentication solutions can be a powerful tool for businesses. It offers an efficient, secure, and cost-effective way to ensure compliance with the regulatory requirements and protect data. This discussion will explore how blockchain can be used to create secure authentication solutions that are GDPR-compliant. We will look at the advantages of using blockchain, the challenges involved, and how to go about implementing a secure authentication solution using blockchain.
How IoT, Blockchain, and Cybersecurity Can Improve Authentication Security. The need for secure authentication is critical in today’s digital world. As technology advances, organizations need to find ways to protect their systems and data from malicious attacks. Fortunately, the Internet of Things (IoT), blockchain, and cybersecurity strategies offer a variety of solutions that can help strengthen the authentication security. With the help of these technologies, organizations can deploy robust authentication protocols that can better protect their networks, devices, and data. This discussion will show how IoT, blockchain, and cybersecurity can be used to improve authentication security and why it is important to do so.
