1、 Storage and prediction framework of battery life of Internet of things devices based on deep learning network and blockchain

With the deepening of digital process , There is a growing need to automate entities .IoT The data generated by Internet of things devices needs to be processed accurately in a safe way . The success of this scenario requires the blockchain as an immutable data store to improve the overall security and trust , This helps to reduce the pressure on the adaptability of the entire automation system .

This study focuses on a specific use case —— Real time deployment on Chicago park area beach IoT The Internet . Real time data collected by various sensors is used in a deep learning network IoT Sensor battery life prediction model . The model proposed in this paper can help the government to plan for battery replacement in advance , So as to provide uninterrupted service . Because of the sensitivity and security requirements of these data , The predicted battery life value is stored on the blockchain to form an unforgeable record .

2、ACeD： Scalable data validity Oracle

A popular solution for offline computing and on chain storage is to submit the hash of the data off the chain to the chain . This mechanism has been identified as a potential stall attack ： The block corresponding to the commit hash may become invalid on any honest node . A straightforward solution is to broadcast all blocks across the network , In order to avoid this data validity attack , But the solution doesn't scale well .

In this paper , We propose a scalable solution to this data validity problem , ACeD, The communication complexity is O(1), As far as we know, this is the first solution to this problem . The key innovation is the new agreement that we're proposing , It only needs N Each node receives O(1/N) Block of , So the data gets a distributed availability guarantee .

Our plan will coding-theoretic The design is embedded in the Merkel tree submission , So as to ensure the efficiency and the reconstruction of imitation tampering . This scheme is different from asynchronous verifiable information step by step and encoding Merkel tree . In Ethereum Kovan The implementation on the test network shows excellent performance , It can reach... Per second 10000 Transaction throughput , also gas Reduced costs 6000 times .

3、 be based on Hyperledger Fabric Analysis of information lifetime in real-time monitoring network of blockchain

Information longevity （AoI） It is a recently proposed index for quantifying the freshness of data in real-time condition monitoring system . In this paper , We make use of AoI The index explores based on Hyperledger Fabric Blockchain monitoring network （HeMN） Data freshness of . stay HeMN In the network , Status updates from the data source are sent via an uplink link and recorded in HyperledgerFabric Blockchain network . Asked to ensure the freshness of the data , We calculate based on transmission delay and formula delay AoI The probability of indicator failure , utilize Fabric The analysis results are verified by the network , And the probability of successful transmission is investigated AoI Failure probability affects efficiency .

4、 Ethereum contract smart corpus

Many real-world software engineering studies indicate the availability of source code 、 The need for filtering and sorting warehouses is obvious . In the last few years , Ethereum blockchain Browser service has become used to explore 、 Search for Ethereum blockchain transactions 、 Address 、 Tokens, 、 Smart contract source code 、 A popular item of price and other activity data on the chain . Obtain useful information for software engineering research from the above services , For example, smart contract software metrics , There may be a lot of subtasks to complete , For example, search for specific transactions 、 analysis HTML Format and filter the duplicate code of smart contract .

In this paper , We propose the concept of intelligent corpus , The corpus contains the latest smart contracts Solidity Source code and metadata about contracts . This paper presents the design and initial implementation of the intelligent corpus ,

5、 Blockchain and decentralized Internet ： expectation 、 Trends and challenges

Blockchain has had an impact on current technology , It revolutionized the financial industry through the use of digital cryptocurrencies and decentralized features . With the current pursuit of decentralized Internet , From the infrastructure and protocol layer to the service and application layer, many methods have been proposed to achieve this goal .

This paper focuses on the use of blockchain to provide reliable and secure decentralized computing system , This paper reviews the methods based on blockchain . To achieve decentralization , This paper makes an in-depth study from two aspects . One is consensus algorithm , We think PoP、Paxos and PoAH Enough Internet architecture to enable blockchain . The second aspect is the impact of future Internet technology on blockchain , The combination of the two will help to improve the existing defects and further optimize the decentralization of the Internet .
