Over the course of time, electronic voting has evolved as a substitute for paper ballot voting to decrease redundancies and inconsistencies. Due to the many security and privacy vulnerabilities experienced over time, the past results of e-voting in the last three decades indicate that it has not been very successful. All cryptocurrencies are actually based on block chain. Block chain is based on the principle of distribution and decentralization. It is a continuous and continuously growing ledger that holds, in a secure, chronological and immutable way, a permanent record of all the transactions that have taken place. Value in a block chain can be anything. In the case of cryptocurrencies, it takes the meaning of money or currency. While in a game it takes the form of points or score. The value can take the form of a vote or a ballot while e-voting. The blockchain can be used in this article to pass votes between two parties. In our case, the electorate is one party and the candidate who earns the vote is the other. Without having a controlling central authority body, the block chain can be implemented in a more stable manner in mass electoral voting practise. A voting system that uses a more stable, tamper-proof block chain (immutable to voting modifications either by other voters or by any third party) and is cost-effective.

There has been an increase in the road trafficas well as the rail traffic , accidents at level crossing has increased and this has caused the concern for the Indian railways. There are certainly many ways to solve this issues but there are major concerns regarding its feasibility for the current environment. Along this factor the cost factor remains the major concern. In this paper, we are proposing a simple solution for the level crossing in which we fix the Radio Frequency tag (RF tag) on the train .we also fix RF tags on each level crossing to communicate with each other, in order to gather the details about the level crossing , train location , train timings and density of vehicles passing the level crossing. These information are send to the database server through Internet Of Things (lOT).
