Mafia cases can actually be prevented by using blockchain technology. Blockchain technology, each certificate of registration can be accessed by anyone and verified by anyone.
So anyone can monitor changes that occur to the certificate documentation. From the start the certificate is issued to the owner until the certificate is sold or given to the next owner.
For information, blockchain is the technology that forms the basis of crypto assets such as bitcoin, ethereum, and the like. Although actually blockchain is not fixed for crypto currency purposes, because it can be applied to various other things.
Basically blockchain was developed to meet the need for an efficient system for recording financial transactions. You could say blockchain is a distributed data center that is shared to every point on a computer network.
The goal is to maintain a secure and decentralized record of transactions.
Besides being able to secure certificates from the land mafia, this blockchain is also suitable for use in the ring of fire area, where natural disasters such as volcanic eruptions are inevitable. So when the physical certificate held by the owner is damaged due to a natural disaster, the certificate has a backup.
Manual registration of certificates and then equipped with blockchain technology will make it easier for all communities to maintain their ownership rights to their land.
If there is a disaster such as the eruption of Mount Merapi, a damaged certificate will have a valid backup with the blockchain, yes, the certificate can be like NFT like that.
Although it sounds complicated, blockchain technology is not complicated at all. Even easier and more transparent than conventional technology.
This is not complicated in practice because it is the same as having a passbook and also having mobile or internet banking in practice, namely manual recording and digital recording, but blockchain is easier and more transparent.
