“…For instance, Espinoza et al [25] describe a design where N-Versioned microservices are placed in between proxies, allowing the system to compare both upstream and downstream request-response pairs. Simillarly, Durieux et al [68] leverage protocol diversity through an HTTP proxy to introduce self-healing for HTML and JavaScript code. These works show that diversity together with proxies can be used to augment targeted aspects of software, e.g.…”

As all software, blockchain nodes are exposed to faults in their underlying execution stack. Unstable execution environments can disrupt the availability of blockchain nodes' interfaces, resulting in downtime for users. This paper introduces the concept of N-Version Blockchain nodes. This new type of node relies on simultaneous execution of different implementations of the same blockchain protocol, in the line of Avizienis' N-Version programming vision. We design and implement an N-Version blockchain node prototype in the context of Ethereum, called N-ETH. We show that N-ETH is able to mitigate the effects of unstable execution environments and significantly enhance availability under environment faults. To simulate unstable execution environments, we perform fault injection at the system-call level. Our results show that existing Ethereum node implementations behave asymmetrically under identical instability scenarios. N-ETH leverages this asymmetric behavior available in the diverse implementations of Ethereum nodes to provide increased availability, even under our most aggressive fault-injection strategies. We are the first to validate the relevance of N-Version design in the domain of blockchain infrastructure. From an industrial perspective, our results are of utmost importance for businesses operating blockchain nodes, including Google, ConsenSys, and many other major blockchain companies.

Summary Companies often employ (i18n) frameworks to provide translated text and localized media content on their websites in order to effectively communicate with a global audience. However, the varying lengths of text from different languages can cause undesired distortions in the layout of a web page. Such distortions, called Internationalization Presentation Failures (IPFs), can negatively affect the aesthetics or usability of the website. Most of the existing automated techniques developed for assisting repair of IPFs either produce fixes that are likely to significantly reduce the legibility and attractiveness of the pages or are limited to only detecting IPFs, with the actual repair itself remaining a labour intensive manual task. To address this problem, we propose a search‐based technique for automatically repairing IPFs in web applications, while ensuring a legible and attractive page. The empirical evaluation of our approach reported that our approach was able to successfully resolve 94% of the detected IPFs for 46 real‐world web pages. In a user study, participants rated the visual quality of our fixes significantly higher than the unfixed versions and also considered the repairs generated by our approach to be notably more legible and visually appealing than the repairs generated by existing techniques.

Summary Over the last few years, the complexity of web applications has increased to provide more dynamic web applications to users. The drawback of this complexity is the growing number of errors in the front‐end applications. In this paper, we present an approach to provide self‐healing for the web. We implemented this approach in two different tools: (i) BikiniProxy, an HTTP repair proxy, and (ii) BugBlock, a browser extension. They use five self‐healing strategies to rewrite the buggy HTML and JavaScript code to handle errors in web pages. We evaluate BikiniProxy and BugBlock with a new benchmark of 555 reproducible JavaScript errors of which 31.76% can be automatically self‐healed by BikiniProxy and 15.67% by BugBlock.
