Parallel analysis of Ethereum blockchain transaction data using cluster computing

Ability to perform fast analysis on massive public blockchain transaction data is needed in various applications such as tracing fraudulent financial transactions. The blockchain data is continuously growing and is organized as a sequence of blocks containing transactions. This organization, however, cannot be used for parallel graph algorithms which need efficient distributed graph data structures. Using message passing libraries (MPI), we develop a scalable cluster-based system that constructs a distributed transaction graph in parallel and implement various transaction analysis algorithms. We report performance results from our system operating on roughly 5 years of 10.2 million block Ethereum Mainnet blockchain data. We report timings obtained from tests involving distributed transaction graph construction, partitioning, page ranking of addresses, degree distribution, token transaction counting, connected components finding and our new parallel blacklisted address trace forest computation algorithm on a 16 node economical cluster set up on the Amazon cloud. Our system is able to construct a distributed graph of 766 million transactions in 218 s and compute the forest of blacklisted address traces in 32 s.

Integrating Blockchain Platforms With Big Data Solutions for Regional Innovation Development

The chapter discusses the creation of a mechanism for ensuring reliable and secure interaction among participants in regional innovation systems based on the establishment of smart contracts in the blockchain. The technology allows to reduce the possibility of fraud by dishonest participants, as well as to exclude the need for a third party by transferring its functions to a smart contract. This is important for ensuring confidential and transparent relations between participants in innovative projects, as well as with interested subjects of social and economic activities in the regions. The Ethereum blockchain platform was chosen to create smart contracts. On its basis, there were developed components to perform transactions in contracting, creating, and implementing innovations, transferring intellectual property rights, using rights and licenses for innovation, etc. The main component of the system is a distributed transaction register with digital copies of innovation objects.

Evolution of Distributed Transaction Towards Microservices Architecture

Major evolutions have took place starting with primary structure counting on initiated request via way of means of a customer to a processing facet known as the server. Such architectures had been now no longer sufficient to manage up with the quick ever-growing range of requests and want to make use of community bandwidth. Mobile sellers tried to triumph over such drawbacks however did cope up for see you later with the developing era platforms. Service Oriented Architecture (SOA) then developed to be one of the maximum a success representations of the customer-server structure with an introduced commercial enterprise price that offers reusable and loosely coupled services. SOA did now no longer meet clients and commercial enterprise expectancies because it changed into nevertheless counting on monolithic systems. Resilience, scalability, rapid software program shipping and the usage of fewer assets are incredibly applicable features.

Overview of Blockchain Technology in urrent Times

Blockchain is a distributed transaction and data management technology that was developed initially for the Bitcoin cryptocurrency. Since 2008 when this idea was coined, the interest in Blockchain technology has been on the rise due to its core qualities that provide data integrity, security and anonymity without third party organizations in control of the transactions, and therefore it creates interesting research areas, especially from the view of technical challenges and limitations thus the reason for the interest in Blockchain. The objective is to understand the current research topics, challenges and future scope regarding Blockchain technology.
