Contents 1. Cadastral records in Croatia 2. Digitization 3. Digital registries in Croatia 4. Long-term data management 5. Blockchain 6. Conclusion 2
1. Cadastral records in Croatia Registering realty properties and technical data on land dual system cadastre kept by State Geodetic Administration regional cadastral offices land registers kept by municipal courts Tradition from 19thCentury 3
2. Digitization Evidence of title recorded in the land registry records enable right of ownership land-related rights legal transactions of ownership Digitization evidentiary value needs to be secured and safe from any unauthorised manipulation 4
3. Digital registries in Croatia Digital registries need to be cleaned from errors some reambulation is necessary Challenges high costs increase the number of officials owners to confirm agreement with the data harmonization of records of land registry and cadastre 5
4. Long-term data management Digitized and harmonized data publically available centrally stored in a registry offering API connections The need to secure evidentiary value of the records provide proof that the information is correct Result reduction of corruption transparency reliability 6
5. Blockchain Distributed ledger technology (DLT) Uses append-only principle Chains blocks of hash values Peer-to-peer consensus Decentralization of control over truth Immutable representation of transfer of possession available to all participants 7
5. Blockchain Blocks' creation direction Distributed ledger Distributed ledger Block n Block n+1 Top hash Top hash Hash of the previous block Hash of the previous block Block hash Block hash [ ] [ ] [ ] [ ] Block documents Block documents 7d8c5b62dcb44023 3f7eaac1ec49e4c3 86b8089c37d69ab5 1bc674b8877cb032 8
5. Blockchain EnigioTime blockchain aggregator (time:beat) Shared ledger timestamped verification block time sealed block Blockchain aggregator Clock document / record hash receipt (chain of proof) Digitization / digital records Land registry Users 9
6. Conclusion Blockchain true archival technology Registering hash values of the land registry records in the blockchain confirm integrity existence or creation at a point in time confirm sequence support/enhance non-repudiation improve validation 10
