Nowadays everything seems to be original and it's being herculean task to identify which is not real. It may be a currency for people or valued currency for students such as certificates. A lot of fraudulent parties have made money by encouraging the duplicate certificates in society. As a result, low talented or inefficient people are getting more and they are being responsible for the degradation of any nation’s value. A blockchain-based certificate is a prime solution for the above problem. In this work, would like to discuss the functioning of a smart contract in favor of Issuing, verifying, and revoking the certificates through gas value[9] deductions. Thus our certificate can provide the added assurances of evidence of origin in a transparent manner using.
This research work proposes a novel and comprehensive electronic cheque transactions framework. The proposed e-cheque system is free from the various security attacks such as alteration of the e-cheque, double spending of e-cheque, counterfeits e-cheques. The e-cheque generated in the proposed system can be deposited electronically or physically via teller machines. This facility provides greater flexibility to the customers of the banking system. The proposed system also provides space for professional miners to participate in the e-cheque transaction system by performing mining's and earn incentives. As the customer's perspective of security, the proposed system uses digital signature and cryptographic hash in each transaction hence it is a completely secure system. The existing CTS based cheque clearance request requires at least one day to clear a cheque which could extend to two or three days but the proposed system requires only 1.65 seconds for clearing any e-cheque.

The IoT ecosystem is evolving quickly, developing several applications in different sectors. The majority of these applications use centralized infrastructures something that poses several challenges especially related to trust and data security. Recently, blockchain has been introduced as an effective solution to IoT applications trying to provide solutions to these challenges. In this paper, we introduce a new decentralized IoT application using blockchain technology, namely, ParkChain. The ParkChain application operates in a way that no one can delete, revert, hack or question the time a registered vehicle securely entered a parking area. In order to evaluate ParkChain, we have implemented the smart contract on top of Ethereum Blockchain along with a traditional Image Processing / Computer Vision approach for License Plate Recognition, and using a Raspberry Pi we control the access on a parking place. We report on several experiments that assess the performance of ParkChain application.

Every year lakhs of students graduating from different university, after passing from university different students have different plans. All students who graduated will have different certificate such as marksheets, degree certificate, best performance certificate and etc. Some students have plans to get employed in companies or to do higher studies. Wherever students go they need submit the certificate for important reference. Due to lack of anti-forge mechanism some started to forge the certificate to get the employed or for further steps. In the digital certificate verification based on blockchain done only for the degree certificates. In the proposing system along with the degree certificate entire personality and behaviour activities of the person using personal id will be uploaded in blockchain. Because of unmodifiable property it is stored in block chain. Initially the student request for the e-certificate by uploading certificate or personal id to electronic certificate system. If requesting for e-cert then the system will review certificate from the university or schools or from organization and get the assurance and store the serial number and e-certificate to the block chain. The system will be generating the QR code and send it to the user. when applying for company user will send only the certificate serial number and QR code received from the e-certificate company. Â
