“…The consensus layer defines how nodes agree on a ledger and resolve inconsistencies, the data model layer defines how data is stored, the execution engine layer defines how a distributed ledger becomes an execution environment for computer programs, and the application layer defines what type of applications can be built on top of DLT. Similarly, a slightly different four-layer hierarchical structure, consisting of network (defines how nodes are connected), protocol (analogous to the consensus layer), ledger (analogous to the data layer), and application layers, was defined in [4].…”

“…To use realistic network parameters (e.g., network latency and bandwidth), Bitcoin-Simulator automatically splits the percentage of 'Other' between the regions based on existing proportions (see Table 6). To have comparable results, we have used this based on hashers' IP addresses connected to mining pools 4 .…”

In recent years, distributed ledger technologies, and especially blockchain, have gained tremendous interest from academia, government, and industry. Although various blockchain-based solutions were created, the lack of tools to evaluate these complex distributed systems may hinder the development of the field. Many advantages of blockchain systems can be demonstrated only at large scales, e.g., using thousands of nodes. An investigation of different implementations and design choices is complicated and hardly feasible on real systems. Meanwhile, blockchain simulators give the possibility to repeat the complex real-world processes at a low cost. This work provides the first and an up-to-date systematic review and empirical analysis of blockchain simulators. Simulators are easily extensible and can test the performance of distributed ledgers using different settings and parameters on a single computer. The features and limitations of selected simulators are summarized and experimentally validated. Finally, recommendations for potential future research directions in the field are provided. INDEX TERMS Bitcoin, distributed ledger technology, blockchain, simulators, systematic review.

“…They seek a way of publishing the voting information to later allow to verify and audit the election. With the apparition of Bitcoin (Satoshi, 2008), Blockchain technology proved itself as an effective, distributed and decentralized public ledger (Belotti et al, 2019;Paulavicius et al, 2019). Since then, various voting protocols based on blockchain have appeared (e.g.…”

Voting systems are as useful as people are willing to use them. Although many electronic election schemes have been proposed through the years, and some real case scenarios have been tested, people still do not trust electronic voting. Voting is not only about technological challenges but also about credibility, therefore, we propose a voting system focused on trust. We introduce political parties as active partners in the elections as a mechanism to encourage more traditional electors to participate. The system we propose here preserves elector's privacy, it operates publicly through a blockchain and it is auditable by third parties.

“…There are several articles which use the bibliometric analysis methods to study numerous researches in the field of blockchain. Paulavičius et al (2019) provided a comprehensive comparative analysis of the most popular blockchain platforms, and paid special attention to the development of consensus protocols. Dabbagh et al (2019) found out the most popular investigation areas, authoritative journals, influential publications and fund organizations.…”

Blockchain is a decentralized database, which can protect the safety of trade and avoid double payment. Due to the widespread attention of researchers, the studies of this field have increased sharply in recent years. It is meaningful to reveal the development level and trends based on this literature. This paper adopts bibliometric methods to study the collaboration characteristics from the levels of author, institution and country. Furthermore, several kinds of collaboration networks and their centrality analysis are also presented, which not only display the development level and collaboration degree but also the evolution of author collaboration modes in different phases.
