And other public single-chain blockchains have the same problem. In this paper, we propose a practical new protocol called Plume to achieve consensus with fast finality by utilizing a (slow) traditional blockchain. Plume combines the DAG structure and traditional blockchain to increase throughput and speed up confirmation. DAG structure is proposed to increase throughput, but how to construct a secure consensus protocol based on DAG is pretty hard. In Plume, we use the traditional blockchain to generate a randomness which is used to generate fast blocks in DAG. And the order of fast blocks in DAG is dependent on a global clock and a hash function. Same as bitcoin, Plume is a probabilistic protocol. However, due to DAG structure, the creation rate of blocks in Plume can be higher without reducing security. Thus the confirmation time of blocks can be accelerated. This paper also analyzes the probability of confirmation in different conditions and also proves that Plume is secure no matter the randomness from traditional single chain is unbiased or not. At last, this paper simulates performance with 1000 nodes using NS-3. The throughput can be improved to 400 Tps in the case that block size is 100K bytes and time interval of fast block is 1 second. Also the confirmation time can be reduced to within 2 minutes in the case that block size is 10K bytes and time interval is 1 second.","PeriodicalId":431685,"journal":{"name":"2021 2nd Asia Service Sciences and Software Engineering Conference","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132387663","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}

A ledger maintains records of data transactions as well as assures the correct execution of processes attached to data. Consistency across processes and parties is achieved by means of consensus building. However, scalability is a major concern when and significant amounts of data need confirmation. When digitalizing existing business processes with serious amounts of data, scalability becomes a pivotal objective. Hence, technical means for information compression become a vital asset. This paper presents a novel approach for data aggregation. On the one hand, data are aggregated in order to merely maintain an audit certificate of the aggregate on the ledger. On the other hand, provenance of raw data aggregated can be traced and proven correctly. Hence, audit services for information exchange in business relationships can scale, while raw data of supplier parties must not be unveiled in detail. We present a novel architecture for efficient data aggregation, while ensuring smart contracts and their main functionality of processing relevant process data. German waterway transportation serves as evaluation scenario. Moreover, decentral identity management is introduced as anchor element of our DLT-enabled ecosystem for business collaboration. Hence, preserving sovereignty and safety of personal data can be assured for M2M economies.","PeriodicalId":431685,"journal":{"name":"2021 2nd Asia Service Sciences and Software Engineering Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122942333","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}

TheChain solves these problems by introducing the intersection of regions as an incentive before allowing validators to nest a client directory. Intersecting their operating territories forces them to keep a watch over each other. The definition of privacy can take many forms, starting from the right to be forgotten beside being away from public attention. Although the pseudonymity of the user within the network can enhance the user's privacy, several pieces of research have studied the techniques to take advantage of the network structure to identify the users of pseudonyms. Moreover, two models have been used to record the updated exchange of values within the blockchain system, which are the unspent transaction output (UTXO) and the balance model. The UTXO suffers from duplication of information and the balance model suffers from having a single point of entry. This paper introduces TheCoin model that defines the protocol of the exchange of valuable datum within TheChain system. The solution has introduced a novel approach of initiating the transaction from the receiver side by taking advantage of mobile agents empowering a topology hiding to the network. Billing within the platform has been introduced to allow advanced contractual logic to be adopted into the system on the information level. Moreover, traceable fuzziness has been used to eliminate duplication. The paper presents an evaluation of the TheCoin model in terms of system security, block size, and search performance.","PeriodicalId":431685,"journal":{"name":"2021 2nd Asia Service Sciences and Software Engineering Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133250986","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}
