From this link, I saw that Distributed Ledger Technology (DLT) can bring the secure functioning for a decentralized database because it is governed by the rule of networks as well as avoiding cyber-crime.
However, the website said that
DLT has great potential to revolutionize the way governments, institutions, and corporations work. It can help governments with tax collection, the issuance of passports, recording land registries and licenses, and the outlay of Social Security benefits as well as voting procedures.
I am wondering how DLT can help the governments in tax collection and passport issuance as said above.
