Paper Title: Blockchain-as-a-Service: A Pure Chain Approach
Journal Name: Blockchain: Research and Applications
Abstract: Technological advancements have fostered ubiquitous connectivity, driving
the adoption of cloud computing and cloud-based services and applications
for maintenance and management purposes. Consequently, cloud comput-
ing and cloud-based services have gained popularity for their scalability and
efficiency in maintenance and management. However, such interconnected
systems are inherently vulnerable to cybersecurity threats, including unau-
thorized access, data breaches, and others. Blockchain technology, initially
popularized through cryptocurrencies, has proven to be a robust and re-
liable solution for various applications beyond financial transactions, such
as supply chain management and secure data sharing. The integration of
blockchain with cloud computing has given rise to the concept of ”Blockchain
as a Service” (BaaS), which provides developers with scalable and ready-to-
use blockchain frameworks without the need for backend management. The
current blockchain network has limitations such as low transaction per sec-
ond (TPS), prolonged mining times, and other challenges that make it dif-
ficult for certain service-oriented applications. To address these issues, this
paper introduces a hybrid on-off chain, edge-enabled BaaS solution called
P ure Chain for service computing. P ure Chain refines the consensus al-
gorithm, enhances the mining process, and enables seamless edge-supported
online-offline hybrid transactions. Moreover, modified blockchain layers to
improve efficiency and scalability. P ure Chain facilitates blockchain-enabled
services and smart contract deployment in a cloud computing environment. P ure Chain optimizes energy consumption and delivers transaction speeds
that are 12 times faster than conventional blockchain networks.
