Abstract: Block chain is also called as chain of blocks i.e. it is collection of technologies or collection of Technologies or a bit like a block chain sack of Logo From the sack y can collect different bricks and arrange them some particular way/different way to create a chain blocks .It is decentralized i.e. no any central control or authority assigned to it .It is simple. Easy to understand and work the system. New blocks are added at the end of the block chain .It uses data structure-link list-also called as linear data structure, stored at contiguous location in work on concept of pointers. They form a chain in continuous way using array ,doubly link list-pointers are used for fast and speedy execution ,it traverse in forward direction –move ahead, backward direction-move back, operations like addition & deletion of node can be efficiently done In this paper the small basics of Blok chain engineering i.e. permission accesses, properties with its few drawbacks are studied. Some projects of Blok chain Engineering were referred with its some good and bad features during the working phase. This paper aim is to find drawbacks related to the Block chain combination and working in the various fields of smart city.
