On the use of blockchain and smart contract, we observe that some existing lottery and gambling games involve one single source to produce randomness. As known, Fomo3D uses the game state to determine the winner, whereas TrueFlip uses the blockchain state (at a specific point in time). Those system do not rely on significant randomness extraction. In this paper, we present a lottery DApp and implement it by using smart contracts. In this DApp, the randomness is determined not only from game and blockchain states, but also from committees.","PeriodicalId":314490,"journal":{"name":"2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127392541","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}

It is argued that logics with the ability to express properties of strategies of players in a multi-agent setting are conceptually useful for this purpose, although ultimately, the less expressive setting of temporal logic suffices for verification of concrete implementations. This is illustrated through the use of a model checker to verify atomic swap smart contracts in on-chain and cross-chain settings.","PeriodicalId":314490,"journal":{"name":"2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121903047","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}

While this trust model strengthens the connectivity among ASes, it results in an attack surface which is exploited by malicious entities to hijacking routing paths. One such attack is known as the BGP prefix hijacking, in which a malicious AS broadcasts IP prefixes that belong to a target AS, thereby hijacking its traffic. In this paper, we proposeRouteChain: a blockchain-based secure BGP routing system that counters BGP hijacking and maintains a consistent view of the Internet routing paths. Towards that, we leverage provenance assurance and tamper-proof properties of blockchains to augment trust among ASes. We group ASes based on their geographical (network) proximity and construct a bihierarchical blockchain model that detects false prefixes prior to their spread over the Internet. We validate strengths of our design by simulations and show its effectiveness by drawing a case study with the Youtube hijacking of 2008. Our proposed scheme is a standalone service that can be incrementally deployed without the need of a central authority.","PeriodicalId":314490,"journal":{"name":"2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC)","volume":"568 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121005153","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}

However, limited resources, such as bandwidth or node computational power, can lead to network congestion when nodes try to issue more transactions than the network can handle. Consequently, priority criteria are necessary to determine whether a transaction should be accepted or not. In this paper, we present a novel adaptive rate control algorithm for the Tangle, a new-generation distributed ledger allowing large throughput. Our approach combines various concepts, such as resource tests and Proof-of-Work with dynamic difficulty. Our algorithm not only serves as an anti-spam mechanism, but also achieves fair representation. This is to be contrasted with pure Proof-of-Work blockchains, which lead to wasteful mining races.","PeriodicalId":314490,"journal":{"name":"2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130462214","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}

In order to solve the trustless problems between enterprises, many permissioned blockchain platforms are proposed in recent years. Hyperledger Fabric is a permissioned blockchain which is comprised of chaincode, endorsing peers, ordering service, committing peers and membership service. Fabric provides identity authentication, transactions encryption and high performance. Hence, decentralized application based on Fabric can be applied among enterprises to implement the immutable and high throughput for transactions. However, some limitations still exist in Fabric framework. This paper surveys the risk of non-deterministic transactions in Fabric, which can be caused by read-write conflict and transactions order dependency. Transactions are judged to be invalid by committing peers when read-write conflict exists. Besides, transactions submission order may be disrupted during endorsing and ordering. Both of the two risks can make the final transaction execution result non-deterministic. Finally, a solution of cache layer on Fabric client is proposed to solve the risk of non-deterministic transactions.","PeriodicalId":314490,"journal":{"name":"2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125539304","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}

In particular we address the scalability problem by reducing the storage and communication costs using a lossy compression scheme.
