How blockchain tech can help the goverment [WIP]

Note: This is WIP article, as I gather more info on this tech, will update this post accordingly.

The main advantage of blockchain is immutability.

Unlike traditional database, no-one can modify the existing mined data in the blocks unless you are controlling the 51% of the network.

A block can be mined only if the majority of the miners and peers validate the block, then only the block can be added to the chain.

Similarly, if an existing block has to be changed, it renders all the blocks mined after it invalid .. as every block calculates the hash based on the previous hash. If the previous block's hash is changed, the next block which is dependant on this changed block will also have to re-calculate and change it's hash.

But the other peers will recognise this as a malicious peer and does not recognize the version of the ledger.

How this can help the govt?

• Goverment/political party makes promises before elections as manifesto, we can store that info on blockchain.
• Goverment has to show accounts of how it is planning to spend the budget and the how money is spent
• Tracking the numbers of vaccines/scholarships etc
• Issuing certificates like land registration, educational qualifications, date of birth, marriage records etc

So in ideal democracy, all the interested stakeholders can be peers, who will immediately invalidate a peer's chain if someone tries to change the data of existing mined blocks(meaning existing promises made by govt :p).

Unknowns:

While adding a block, it need not be validated by miners, as typically one entity is making a promise, unless this is a transactional data, which is dependant on previous blocks.

Alternatives

• Internet Archive can hold the webpages with timestamps, but it can hold multiple versions of the same page which will make it tedious in comparing/auditing.
• Video record of the promises made, but videos can be morphed/changed with the current deep AI tech.
