Blockchain-based approaches are increasingly being used to provide distributed trust and security in Distributed Energy Trading (DET). However, the state-of-the-art solutions lack scalability, privacy, interoperability, and often have large computational overheads hindering their mainstream adoption for sustainable development. To address these challenges, this paper proposes a multi-relationship network framework (RNF) that uses hypergraphs to organise participants in energy trading networks based on high-order relationships (rather than pairwise) for flexibility, interoperability, data privacy, and reduced resource consumption. Results indicate that the proposed framework outperforms the baseline in terms of: enabling value transfer across multiple blockchain-based DET systems; reducing computational costs and achieving energy efficiency for sustainable development.

We initiate the study of vote delegation in a costly voting setting and compare its performance to conventional voting. Our central insight is that if the number of malicious voters is comparatively low, delegation dominates conventional voting. If the number of malicious voters is moderate, then conventional voting tends to be better than vote delegation. If the number of malicious voters is high, both voting methods fail to deliver a positive outcome.

One of the major challenges of cryptocurrendes is the lack of confidentiality, Without confidentiality, the amount of each transaction on a blockchain is not private. While confidential transactions can hide transaction amounts, its storage overhead is extremely high (e.g., 10~20X). This substantial overhead significantly raises users’ overheads in bootstrapping and impedes new nodes, especially for resource-limited devices.We devise a new method, referred to as EcoBoost, to advance the effidency of bootstrapping for blockchains supporting confidential transactions. Specifically, we harness random sampling to verify the correctness of confidential transactions with high probability. As a result, the verification overhead is sublinear with regard to the number of transactions (compared to linear in current solutions). Our experiment results show that, if Bitcoin implements confidential transactions, EcoBoost can save over 86% storage and verification time in bootstrapping but still detect bogus transactions with a probability of 99%.

Blockchain has become a promising technology in distributed systems in recent years, but scalability remains a major problem. The traditional approach to scalability, namely sharding, does not solve the problem easily because the process of interleaving blocks stored in different shards to create a unified master ledger introduces overhead. This paper examines two techniques for interleaving the shards of permissioned blockchains, which we refer to as strong temporal coupling and weak temporal coupling. We implement these techniques in a prototype system with a Bitcoin-like transaction structure, using the EPaxos consensus protocol for transaction ordering. Our experimental results show that strong coupling can achieve lower latency as compared to weak coupling but same level of peak throughput. However, strong coupling requires all shards to grow at the same rate, and cannot tolerate any shard failure. In contrast, the higher latency of weak coupling is because of the consensus strategy it uses to order the blocks. However, if shard failure occurs, weak coupling can still make progress without stalling the whole system.

On the blockchain, cryptocurrencies play a role similar to cash, while cryptographic tokens are a universal tool for handling rights and assets. Software wallets interact with blockchains in general and with smart contracts (on-chain programs) in particular. Some wallets are realized (partly) as smart contracts with the intent to increase trust and security by being transparent and by offering features like daily limits, approvals, multiple signatures, and recovery mechanisms.Ethereum is the most prominent platform for both, tokens and smart contracts, and thus also for wallet contracts. We discuss several methods for identifying wallet contracts in a semi-automatic manner by looking at the deployed bytecodes and their interaction patterns. Furthermore, we differentiate characteristics of wallets in use, and group them into six types.

Today, Internet of Things (IoT) devices mostly operate in enclosed, proprietary environments. To unfold the full potential of IoT applications, a unifying and permissionless environment is crucial. All IoT devices, even unknown to each other, would be able to trade services and assets across various domains. In order to realize those applications, uniquely resolvable identities are essential. However, quantifiable trust in identities and their authentication are not trivially provided in such an environment due to the absence of a trusted authority. This research presents a new identity and trust framework for IoT devices, based on Distributed Ledger Technology (DLT). IoT devices assign identities to themselves, which are managed publicly and decentralized on the DLT’s network as Self Sovereign Identities (SSI). In addition to the Identity Management System (IdMS), the framework provides a Web of Trust (WoT) approach to enable automatic trust rating of arbitrary identities. For the framework we used the IOTA Tangle to access and store data, achieving high scalability and low computational overhead. To demonstrate the feasibility of our framework, we provide a proof-of-concept implementation and evaluate the set objectives for real world applicability as well as the vulnerability against common threats in IdMSs and WoTs.

Various kinds of certificates are used in international trade, and it is important for trade participants to know about their authenticity and status. One example are phytosanitary certificates, which record that exported plant-based materials meet biosecurity requirements of destination countries. An electronic "ePhyto" certificate system is being developed to be operated by the United Nations (UN). An ePhyto certificate is transmitted from the national plant protection organisation (NPPO) of the exporting country to the NPPO of the importing country. The UN system provides a secure communication channel between pre-registered NPPOs. However, industry participants who are not connected to the UN system are not able to confirm the authenticity of an ePhyto certificate, and whether that ePhyto certificate has been revoked or reissued. In this paper, we describe a blockchain-based system and its software architecture that could augment the emerging ePhyto certificate system by adding a tamper-proof for public users to check the authenticity and status of ePhyto certificates.

Blockchain is a service operated by a peer-to-peer type distributed network, and protocol control such as JSON-RPC is implemented as the interface for flexibility and operability. However, attacks that use protocol control against vulnerable and unmanaged interfaces have been reported. One of the methods to track cyber attacks on such a malicious user’s network service is a honeypot that imitates the service and acquires attacker’s behavior information. In this research, focusing on the Ethereum network, the behavior of malicious users is clarified using malicious communication history sent to simple honeypots installed in nine countries, Ethereum network information and darknet arrival packets. By analyzing these, the behavior of attackers and the tendency of requests were elucidated, and primary safety measures were established.

The notion to digitally articulate, execute, and enforce agreements with smart contracts has become a feasible reality today. Smart contracts have the potential to vastly improve the efficiency and security of traditional contracts through their self-executing autonomy. To realize smart contracts several blockchain-based ecosystems exist. Today a prominent representative is Ethereum. Its programming language Solidity is used to capture and express contractual clauses in the form of code. However, due to the conceptual discrepancy between contractual clauses and corresponding code, it is hard for domain stakeholders to easily understand contracts, and for developers to write code efficiently without errors. Our research addresses these issues by the design and study of a domain-specific smart contract language based on higher level of abstraction that can be automatically transformed to an implementation. In particular, we propose a clause grammar close to natural language, helpful coding abstractions, and the automatic integration of commonly occurring design patterns during code generation. Through these measures, our approach can reduce the design complexity leading to an increased comprehensibility and reduced error susceptibility. Several implementations of exemplary smart contract scenarios, mostly taken from the Solidity documentation, are used to demonstrate the applicability of our approach.
