As a new and subversive technology, blockchain is an active research field and graduation project topic. This article lists the latest block chain of a group of papers, I hope to be able to choose the block chain graduation design of the students are helpful, this is the fourth block chain graduation design paper series compiled by Hui Zhi net.
1. Bitcoin network entity activity analysis and visualization
This paper proposes a visual analysis tool, Bitcoinduite, to explore and analyze the financial activities in the Bitcoin network.
Bitcoin is the world’s largest digital cryptocurrency, and it’s challenging the traditional financial system — bitcoin users can bypass the traditional banking system and transfer money in (pseudo) anonymous ways. While bitcoin transactions are recorded on publicly accessible ledgers, we don’t know much about how bitcoin is used by the participants (what we call entities). Bitconduite provides an entity-centric view of transactions, guided workflows to help non-technical experts explore the behavior patterns of Bitcoin entities, as well as similarity clustering analysis, multi-scale transaction data exploration, and more. The two use cases included in the paper demonstrate the workflow of the system and its analytical capabilities. At the end of the paper, the use feedback of domain experts is given, and the potential future research direction is discussed.

2. Personal privacy information management system based on blockchain
Blockchain, a distributed ledger of distributed consensus about historical transactions, is the underlying technology for digital cryptocurrencies like Bitcoin, but it also has many applications outside of finance. Blockchain is beginning to appear in other applications because of its security and the fact that it does not require trust from third parties. In this paper, we propose a third party approval management system based on permit-based blockchain, whose policy can be determined by the governing body.
We have completed a proof-of-concept (PoC) implementation using Hyperledger Fabric that provides end users with the ability to control and approve the use of their private information. We detail that the solution can meet the Data Protection Act (DGPR) of the European Union. Although current performance and usability evaluations are limited, our design and implementation can meet seven basic principles of privacy protection.

3. ChainifyDB – Blockchain-based existing data management system
Current licensed blockchain systems are offered in a separate form, requiring users to add a new transaction processing system to an already complex data management system. That seems like a lot of seven, because blockchain and traditional databases have a lot in common. Therefore, this paper proposes an idea of blockchainization of existing data systems, rather than completely replacing them. Unfortunately, this task is more challenging than it sounds: because we want to blockchainize on top of heterogeneous transaction processing systems, we have to abandon some assumptions and introduce more powerful processing models.
Our proposed WLC model creates a highly flexible licensing blockchain layer, which we call ChainifyDB, with the following features: (a) based on proven database technology (b) more secure than existing licensed blockchains (c) providing sophisticated recovery mechanisms (d) six times the transaction throughput of Hyperledger Fabric (e) easy integration with existing heterogeneous databases.

Blockchain games – Byzantine system synthesis and Nash equilibrium
In this paper, the synthesis of blockchain is proposed from two orthogonal perspectives — distributed fault-tolerant system and game theory.
We define a new game theory problem in the context of blockchain and give a Nash equilibrium derivation for this problem.

5. Bdos-blockchain denial of service attacks
PoW consensus blockchains such as Bitcoin have a large amount of capital deposit, but currently there are few denial-of-service attacks against blockchains. This is mainly due to the cost of attacks: known attacks either target individuals or require the control of most system resources.
In this paper, we propose an incentive-based attack: BDoS, which is much cheaper and, to our knowledge, the first incentive-based DoS attack.
