چکیده

Abstract Purpose In this paper, we define the concept of user spectrum and adopt it to classify Ethereum users based on their behavior. Design/methodology/approach Given a time period, our approach associates each with showing trend some behavioral features obtained from social network-based representation Ethereum. Each class has its own spectrum, by averaging spectra users. order evaluate similarity between one user, propose tailored measure adapting context general measures provided in past. Finally, test dataset transactions. Findings We model represent also for (i.e., token contract, exchange, bancor uniswap), consisting suitable multivariate series. Furthermore, an new The core is metric capable measuring degree This Eros distance Extended Frobenius Norm) scenario. Originality/value paper introduces users, which blockchains. Differently past models, represented behavior means univariate series, here proposed exploits Moreover, shows that original does not return satisfactory results when applied spectra, proposes modified version it, reference scenario, reaches very high accuracy. adopts Currently, no multi-class automatic classification exists yet, albeit single-class ones have been recently proposed. Therefore, only way are online services (e.g., Etherscan), where classified after request them. However, fraction thus low. To address issue, present

An Instrument to Classify End-Users Based On the User Cube

End-user computing (EUC) has led to increased end-user productivity and satisfaction. In order to reduce the risks inherent to EUC, organizations should better manage EUC. As a first step different groups of end-users must be identified. Existing classification schemes have weaknesses and fail to capture the different roles contemporary end users play. Cotterman and Kumar (1989) proposed a user...

Defining the Ethereum Virtual Machine for Interactive Theorem Provers

Smart contracts in Ethereum are executed by the Ethereum Virtual Machine (EVM). We defined EVM in Lem, a language that can be compiled for a few interactive theorem provers. We tested our definition against a standard test suite for Ethereum implementations. Using our definition, we proved some safety properties of Ethereum smart contracts in an interactive theorem prover Isabelle/HOL. To our k...

A Novel Acoustic Sensor Approach to Classify Seeds Based on Sound Absorption Spectra

A non-destructive and novel in situ acoustic sensor approach based on the sound absorption spectra was developed for identifying and classifying different seed types. The absorption coefficient spectra were determined by using the impedance tube measurement method. Subsequently, a multivariate statistical analysis, i.e., principal component analysis (PCA), was performed as a way to generate a c...

Applying Smart Objects for Persuading Users to Change Their Behavior

This paper introduces a novel application area of smart objects, changing users’ behavior. By analyzing user contexts acquired by smart objects, applications provide users with appropriate feedbacks to change their behavior. This study demonstrates a concept called ambient lifestyle feedback systems to be used to motivate people to change their undesirable habits to improve their lifestyle. We ...
