1. In Nigeria, it is public knowledge that we deal with a lot if fake and substandard goods but with the help of dApps, the block chain technology can be used to track goods from their manufacturers down to the consumers, verifying their authenticity and help to foster trust in the market place..
Decentralized applications are theoritcal in life practices, the only utility in practice is web3, the real life aspect is not working. Nigeria isn't the only country that has substandard goods and they don't used Dapps to track fake goods. Some of the fake medicine and imported items that are sold in other countries down to Nigeria and their government isn't fighting it using Dapps.
There are other countries that have a traditional system that has reduced substandard goods and the Nigerian government can do it too just that the government will likely reject the idea because the system is corrupt, the people at the top all got rich through the corrupt system of substandard goods.
