Blockchain is the technology behind several digital currencies. A blockchain is a chain of blocks that keeps records of information in a decentralized and distributed network, with digital signatures stored in each block. Because of the distributed nature of blockchain and other unique properties, transactions are more secure and tamper proof. The paper's methodology gives a detailed study of blockchain's fit in the supply chain industry. Data is stored on many chains using a multi-chain architecture in the framework. Additional to the data management model and block structure model, the model contains the data model and container structure model.

Blockchain is the technology which consists of a chain of blocks that store the necessary information including digital signatures with a validation process in a decentralized and distributed type of network. Immutability, transparency and auditability, make the transactions more secure and tamper proof. In Bangladesh if the paper industries use the block chain technology, then their production and transparency will be very high. Blockchain technology can effectively record every asset throughout its flow on the supply chain, contribute to tracking orders, receipts, and payments. In this paper, data is collected from a large paper industry in Bangladesh and also from online databases for comparison. A qualitative thematic analysis has been performed in accordance with the investigative processes that are developed by Creswell. We evaluated the impact of the most influential design and parameters (load) on the resulting commitment. For analyzing the performance of the model, Markovian Non-purging fork join queueing model is used. Finally, the model is studied by the real word data and to show its functionality.

Thepower industry of Bangladesh is not enough sustainable and eco friendly which is governed by anumber of centralized authorities The energy is received from various power plants and then route theenergy to substations and eventually to the consumers which is palpably inadequate to meet the farreaching demand This leads to the load shedding in many areas which is still a burning question from thesocio economic perspective of Bangladesh A significant percentage of people are still deprived ofuninterrupted energy supply and a many more are still out of the energy distribution network due to lackof resources The energy currently available in the country is mainly fossil fuel energy which is neithersustainable nor eco friendly and the centralized distribution of energy requires the transmission of energyat high voltages which has a lower efficiency and adds to the wastage of energy Another core problem isunauthorized connection of energy and intentional faulty meter reading submission by operators whicheventually leads to a momentous loss of revenue, and this creates a sense of skepticism among the massusers on the local authorities responsible for proper energy management From the economic perspective,it is imperative to create a sustainable sector of investment for mass people due to the current fragile stateof stock market and banking system Addressing these issues is obligatory to maintain the economicgrowth of Bangladesh as well as to elevate the lifestyle of mass people The aim of our project is to attainthese milestones by creating a localized energy generation, storage, transmission and distribution systemusing blockchain which exhibits some genuine concern on pertinent areas and solution of the issues.
