How can regular people put an end to this?
Do you think there ever going to be a "clean", free of corruption world? People with no financial interests?
Depends on your definition for Corruption.
According to me corruption can never be eliminated. There will always be people who are powerful, richer and oppression of the weaker section will always exist.
In most countries problem of corruption arises due to Politicians. Corruption and malpractices start from bribing Voters to rigging Voting machines itself.
Blockchain is the best solution to put an end to Corruption as transparency can be maintained in Every Step.
Politicians are just a link in the chain that is corruption. Everyone is involved in it. The common folk, civil servants, politicians everyone. Why don't you count the person who is willing to pay the bribe to save himself from the parking ticket or an applicant paying to have a clean record. So it is not just about politician but also our approach that flames corruption.
Blockchain being the annihilator of corruption. I don't think so.
