“…The most well known smart contract application in digital world is Ethereum, which uses Solidity programming language for coding contracts. Solidity [175] is a contract oriented language, influenced by Javascript, Python and C++. Deficiencies in programming language, execution environment, and coding style can lead to a series of attacks.…”

In this paper, we systematically explore the attack surface of the Blockchain technology, with an emphasis on public Blockchains. Towards this goal, we attribute attack viability in the attack surface to 1) the Blockchain cryptographic constructs, 2) the distributed architecture of the systems using Blockchain, and 3) the Blockchain application context. To each of those contributing factors, we outline several attacks, including selfish mining, the 51% attack, Domain Name System (DNS) attacks, distributed denial-of-service (DDoS) attacks, consensus delay (due to selfish behavior or distributed denial-of-service attacks), Blockchain forks, orphaned and stale blocks, block ingestion, wallet thefts, smart contract attacks, and privacy attacks. We also explore the causal relationships between these attacks to demonstrate how various attack vectors are connected to one another. A secondary contribution of this work is outlining effective defense measures taken by the Blockchain technology or proposed by researchers to mitigate the effects of these attacks and patch associated vulnerabilities.

“…With the development of technology, the wireless charging of EV can be brought to actualization. Maximilian Wohrer [4]The solution proposed in this paper, the trending technology of block chain is high lighted. Initially,the Ethereum platform that offers the smart contract functionality known as EVM is elaborated.…”

An Electric Vehicle (EV) uses one or more traction motors or electric motors for propulsion. Nowadays the Electric Vehicle charging process is grim. An Electric Vehicle employs the concept of getting charged every time the vehicle is done travelling till a certain distance. The abate cost, alluring userfriendly method to maintain and its environment friendly nature makes the EV populous among many people. Yet, there pertains an issue to charge the vehicle as there are not many charging stations installed at every place. In this paper, we provide, block chain based vehicle charging system with reliable transaction. The vehicle has an inbuilt RFID tag, that is read by the RFID reader in the charging station. The RFID Number is transmitted to the server. The block chain technology is used in the server. If the vehicle goes missing the owner can report the theft to the server if the ID is matched the report is sent to the owner by Short Message Service(SMS) and the charging process will not be initiated. If the ID is not matched then the EV charging starts automatically.

“…Security issues in smart contracts has been investigated in many previous works [34] [35] [36]. Though most bugs and system flaws can be prevented by careful implementation and intensive tests, it is virtually impossible to guarantee that a non-trivial smart contract is bug-free.…”

Blockchain technology has attracted tremendous attention in both academia and capital market. However, overwhelming speculations on thousands of available cryptocurrencies and numerous initial coin offering (ICO) scams have also brought notorious debates on this emerging technology. This paper traces the development of blockchain systems to reveal the importance of decentralized applications (dApps) and the future value of blockchain. We survey the state-of-the-art dApps and discuss the direction of blockchain development to fulfill the desirable characteristics of dApps. The readers will gain an overview of dApp research and get familiar with recent developments in the blockchain.
