Block chain is a technological advancement that was developed using a variety of techniques, including math, physics, cryptography, financial models, etc. Block chain is a decentralized, digital ledger of all cryptographic currency exchanges. In this application, the land registration process on the block chain is used. This exchange includes administrative, buyer, seller, and registration office components. They essentially communicate in light of the local land registration process. The admin, seller, buyer, and register office must all register and login on the web page. In order to receive official approval and ship the buyer's purchase, the seller must provide the sub-register office with information about the land including the landowner, size, file, document, price, and other details. To make it easier for customers to monitor exchanges without maintaining a central record of them, all digital currency exchanges are stored in sequential order. The block chain’s application potential is encouraging and has been showing results ever since it started. Although numerous studies on the security and protection issues of the block chain have been conducted, a thorough evaluation of the security of block chain frameworks is still lacking
