Tenders or contracts are generally used by governments and companies to procure goods or services. Wrongful tender management leads to huge losses in case of faulty practices. This includes favoring of contractors, improper record maintenance, lack of transparency, hacking, data modification and other issues. To ensure the complete tender management process is secure and efficient we here make use of block chain tech to solve tender management issues. A block chain is secured by encryption coupled with indisputable block based architecture for transaction management. In this case we make use of Hyper ledger block chain technology to secure transaction based documents along with transactions such as tender documents, applications, bid proposals, company profiles, past records, approving officer details, rejection details to ensure a completely transparent tendering process. Block chain Technology is one of the most popular technologies of present days. This technology has the capability to eliminate the requirement of third party to validate the transactions over the Peer-to-Peer network. Due to various features of Block chain like smart contract, consensus mechanism, network transactions are completed securely, efficiently and timely. This technology is very useful in many areas including medical, IoT, e-Governance services, smart cities, taxation, supply chain, banking etc. In this paper, we discuss the Block chain Technology in detail, its data structure, open source platform like Ethereal and Hyper ledger, technical aspects of this technology, possible applications of this technology, challenges and limitations in adaptation of this technology.
