All the countries around the world are now implementing blockchain in the area of land registrations in India, we should also consider it as a viable option. The blockchain has provided major security benefits in diverse fields. Therefore, this land holding system is implemented using a blockchain architecture. In India main problems in traditional land holding system include space constraints, fraud in land registry, lack of uniformity and poor maintenance of land records, lack of single window title verification and investigation system, fear of destruction of records by force majeure events. Therefore, a blockchain is prepared to aid these problems in order to solve these problems we have analyzed, identified and developed an application with the help of blockchain smart contracts. In this paper we are developing a land holding System to encounter the problems in traditional systems. KEYWORDS: Blockchain, Landholding, Smart contracts, Xamarin and Security. I. INTRODUCTION Although Blockchain technology was found in 1992, the name started to rise when the bitcoin started to grow. A blockchain may be defined as a distributed database incorporating information or a book that marks all the events and transactions, executed and shared among concerned parties. The transactions are verified and information entered can never be erased. Every transaction made had a verifiable record. Blockchain Technology finds its use in financial as well as non-financial sectors. Blockchains are public registers such that all transactions are accumulated in list of blocks. Blockchain is a collection of blocks connected in form of a chain to provide a secure mode of storing data. Each of these nodes are connected using hash cryptography and the chains are distributed over a number of nodes in a network. This serves two important benefits, first, making the chain impossible to attack practically and second, eliminating the hold of a central authority over the data. The Blockchain has becomes very popular in recent times due to its various advantages in almost all of the fields. There are many large institutions around the world which have conducted research around it [14,15,16] and have appreciated its true potential. According to reports we see that the blockchain technologies has passed all the peaks of inflations in growth and still going on strong. It is estimated the technology will reach the efficiency periods in 5-10 years. After this period, it is expected to mature at the end of this period. As the chain is distributed and immutable the data on the chain is transparent and visible to everyone. Besides providing safety and transparency to the data, it also cuts the middle man cost, the delays and the human errors. Blockchain has become one of the safest and automated method of transferring data from one location to another. The chain is verified by thousands of nodes on the network and each block on the chain has a unique record with the unique history. Modifying a block would require modifying the entire chain on the majority of nodes within a short span of time, which makes it practically impossible to be tampered. In recent years these features of blockchain has made it popular in various fields ranging from health sector to supply chain. Basically, it can be implemented in any field involving transaction or transfer of data. [17]its peer-to-peer network and decentralized currency features remove the need of trusted financial intermediators. There are many features provided by blockchain mainly consisting of Hash cryptography, consensus protocol, public and private keys and Distributed peer to peer connection.
