In this model, we defined the standard structure and interface for all Fabric NFTs. This model also supports the extensible structure and interface that accommodates different types of NFTs. To demonstrate how to take advantage of this model, we applied extensible NFTs such as document and signature tokens to a decentralized signature service.","PeriodicalId":328454,"journal":{"name":"Proceedings of the 3rd Workshop on Scalable and Resilient Infrastructures for Distributed Ledgers","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134477778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
{"title":"You Don't Need a Ledger: Lightweight Decentralized Consensus Between Mobile Web Clients","authors":"Kristof Jannes, B. Lagaisse, W. Joosen","doi":"10.1145/3366611.3368143","DOIUrl":"https://doi.org/10.1145/3366611.3368143","url":null,"abstract":"Centralized systems relying on a trusted third party are being replaced by decentralized systems using proof-of-work blockchains to reach consensus between multiple mistrusting parties. Due to the high energy usage of such systems, many solutions using a Byzantine fault-tolerant algorithm to reach consensus have emerged. While those systems solve the energy and safety concerns of proof-of-work blockchains, they still require a peer to store the full ledger and need a complex backend infrastructure to get started. This paper presents a lightweight middleware running in the browser, designed for small businesses and end-users unable to set up a complex private blockchain business network. The middleware for consensus runs entirely in the browser, with only a small server-side component used for the peer-to-peer discovery. We achieve fast confirmation times while guaranteeing safety and liveness for honest users. We also do not maintain a ledger, reducing the overall storage footprint.","PeriodicalId":328454,"journal":{"name":"Proceedings of the 3rd Workshop on Scalable and Resilient Infrastructures for Distributed Ledgers","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121312551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
