1.INTRODUCTION

Land is one of the most important and valuable assets for individuals as well as governments and keepingaccurateownershiprecordsisessentialfor legal security and economic stability. However, traditional land registry systems are mostly centralized and controlled by government authorities.Becauseofthiscentralizednature,these systems are often vulnerable to problems such as fraud, data manipulation, corruption, and loss of records. In many cases, verifying ownership or transferring land takes a long time due to manual processes and the involvement of multiple intermediaries like brokers, agents, and officials. This not only increases the overall cost but also reducestrustamongstakeholders.

Withtherapidadvancementoftechnology,thereisa growing need for a more secure, transparent, and

efficient way to manage land records. Blockchain technology offers a promising solution to these challenges.Itisadecentralizedsystemwheredatais stored across multiple nodes, making it extremely difficult to alter or tamper with records. Each transaction is recorded permanently, ensuring transparency and accountability. This helps build trustamongusers,asallparticipantscanverifythe authenticity of the data without relying on central authority.

By integrating blockchain technology into land registrysystems,manyoftheexistingissuescanbe addressed effectively. The use of smart contracts allowsautomaticexecutionofagreements,reducing the need for manual intervention and minimizing delays. Additionally, decentralized storage systems cansecurelystoreimportantdocumentssuchasland deeds and certificates, ensuring they are always accessibleandprotectedfromlossordamage. Inthispaper,weproposeablockchain-basedsystem for tracking land registry that combines smart contracts and decentralized storage technologies. Thegoalistocreateareliable,secure,andefficient platform for managing land ownership and transactions, ultimately reducing fraud, increasing transparency,andsimplifyingtheentireprocessof landtransfer.

In recent years, blockchain technology has gained significantattentioninthefieldoflandregistryand property management. Many researchers have exploreditspotentialtoovercomethelimitationsof traditionalcentralizedsystems.Severalstudieshave proposed the use of private and permissioned blockchain frameworks, such as Hyperledger, to

enhancedatasecurity,privacy,andcontrolledaccess [1], [2]. These systems allow only authorized participants,suchasgovernmentofficials,tovalidate and update land records, thereby reducing the chancesofunauthorizedaccessanddatatampering.

Other research efforts have focused on the use of smartcontractstoautomatekeyprocessesinland registration, such as ownership verification, transaction validation, and property transfer. By eliminating manual intervention, these systems reducedelays,minimizehumanerrors,andimprove overall efficiency [7], [10]. Some solutions also integrateidentityverificationmechanismstoensure thatonlylegitimateuserscanperformtransactions, therebyincreasingtrustinthesystem[4].

Despite these advancements, existing approaches still face several challenges. One major issue is scalability,asblockchainnetworksmayexperience delays when handling many transactions. Additionally, many systems are complex to implementandrequiretechnicalexpertise,making themdifficulttoadoptinreal-worldscenarios[8], [15]. Another limitation is the lack of efficient storagesolutionsforlargedocumentssuchasland deeds,maps,andcertificates,whichcannotbestored directlyontheblockchainduetosizeconstraints.

Toaddressthestorageissue,someresearchershave suggestedintegratingdecentralizedstoragesystems such as IPFS (InterPlanetary File System). IPFS allows large files to be stored securely off-chain while maintaining their integrity through unique cryptographichashesstoredontheblockchain[12].

Buildingupontheseexistingworks,severalmodern studieshaveproposeddecentralizedframeworksfor securelandregistrationandfraudprevention[19]. However,thereisstillaneedforamorepractical, scalable, and user-friendly system. Therefore, this paper proposes a comprehensive and fully decentralized land registry system that combines blockchain technology, smart contracts, and IPFS. The aim is to create a more secure, scalable, and practical solution for managing land records,

ensuring transparency, reducing fraud, and simplifyingtheprocessofownershiptransfer.

3.PROBLEM STATEMENT

The existing land registry system suffers from multiple challenges that reduce its efficiency, reliability, and trustworthiness. Most traditional systems are based on centralized databases maintained by government authorities or administrative bodies. This centralized approach createsasinglepointoffailure,meaningthatifthe systemiscompromised,corrupted,orattacked,the entire database can be affected. Such systems are also more vulnerable to data loss due to technical failuresorcyberattacks.

Another major issue is the high risk of fraud and unauthorizeddatamanipulation Sincerecordscan be altered by individuals with access privileges, there have been many cases of illegal property transfers, duplicate ownership claims, and forged documents.Thisunderminestrustinthesystemand often leads to legal disputes that take years to resolve.

Theverificationandapprovalprocessintraditional systems is often slow and inefficient. It involves multiple steps, including manual document verification,approvalsfromvariousauthorities,and physicalvisitstooffices.Thisnotonlyincreasesthe time required to complete a transaction but also addstotheoverallcostforusers.

Additionally, there is a significant lack of transparency among stakeholders. Buyers, sellers, and other parties do not have realtime access to reliable land records, making it difficult to verify ownershiphistoryortransactiondetails.Thislackof visibilityfurtherincreasesthechancesoffraudand miscommunication.

Thesystemalsoheavilyreliesonintermediariessuch as brokers, agents, and officials, which increases complexity and operational costs. These intermediariesmayintroducedelays,errors,oreven corrupt practices,makingthe process less efficient
