Special Issue Information

Dear Colleagues,

Blockchain and its applications are popular research topics. Cryptocurrency is one of the most popular implementations in the real world. Presently, a number of cryptocurrencies are being used, e.g., Bitcoin, Ethereum, Ripple, Litecoin, etc. However, the application of blockchain technology is not limited to cryptocurrencies. The immutability, trustless, auditability, and distributed properties make blockchain suitable for application in many business models. For example, Ethereum and Quorum allow blockchains to execute smart contracts, which provide the permissioned blockchain mechanisms to make transactions privately. Moreover, the smart contract mechanism provides many interesting research and application issues, such as the Internet of things, cyber physical systems, Edge computing, social networks, supply chain management, Fintech, and many others.

The aim of this Special Issue is to gather the latest research results concerning blockchain technology and its application in relevant scenarios. Researchers, experts, and scholars are encouraged to present their contributions and research directions in the blockchain area.

Topics of interest include, but are not limited to:

  • Blockchain technologies

○ Blockchain foundations

○ Consensus algorithms

○ Smart Contracts

  • Blockchain security

○ Attacks on blockchain-based systems

  • Blockchain operation and governance

○ Scalability of blockchain-based systems

○ Governance models and experiences

○ Performance of blockchain-based systems

○ Interoperability of blockchains

○ Blockchain standardization

  • Blockchain analysis

○ Transactions analysis

○ Smart Contracts analysis

  • Identity management

○ Privacy and anonymity on blockchain

  • Lightweight protocols based on blockchain
  • Energy consumption issues
  • Blockchain applications

○ Cryptocurrencies

○ Internet of things

○ Smart property

○ Cyber physical systems

○ Cloud and edge computing

○ Supply chain management

○ Social Networking

○ Media production

○ Copyright protection

○ Information hiding

○ Education

Signatures of the Crypto-Currency Market Decoupling from the Forex

Based on the high-frequency recordings from Kraken, a cryptocurrency exchange and professional trading platform that aims to bring Bitcoin and other cryptocurrencies into the mainstream, the multiscale cross-correlations involving the Bitcoin (BTC), Ethereum (ETH), Euro (EUR) and US dollar (USD) are studied over the period between 1 July 2016 and 31 December 2018. It is shown that the multiscaling characteristics of the exchange rate fluctuations related to the cryptocurrency market approach those of the Forex. This, in particular, applies to the BTC/ETH exchange rate, whose Hurst exponent by the end of 2018 started approaching the value of 0.5, which is characteristic of the mature world markets. Furthermore, the BTC/ETH direct exchange rate has already developed multifractality, which manifests itself via broad singularity spectra. A particularly significant result is that the measures applied for detecting cross-correlations between the dynamics of the BTC/ETH and EUR/USD exchange rates do not show any noticeable relationships. This could be taken as an indication that the cryptocurrency market has begun decoupling itself from the Forex. Full article

Research on digital image processing has become quite popular and rapid in recent years, and scholars have proposed various image verification mechanisms. Similarly , blockchain technology has also become very popular in recent years. This paper proposes a new image verification mechanism based on the Merkle tree technique in the blockchain. The Merkle tree root in the blockchain mechanism provides a reliable environment for storage of image features. In image verification, the verification of each image can be performed by the Merkle tree mechanism to obtain the hash value of the Merkle tree node on the path. In addition, the method combines the Inter-Planetary File System (IPFS) to improve the availability of images. The main purpose of this paper is to achieve the goal of image integrity verification. The proposed method can not only verify the integrity of the image but also restore the tampered area in the case of image tampering. Since the proposed method employs the blockchain mechanism, the image verification mechanism does not need third party resources . The verification method is performed by each node in the blockchain network. The experimental results demonstrate that the proposed method successfully achieved the goal of image authentication and tampered area restoration. Full article
