You have tried your best to research and produce good points on this concept dear friend. Blockchain is a type of technology that stores data in encrypted blocks and relies on consensus to validate transactions. It is best known as the underlying technology powering Bitcoin and other cryptocurrencies.

This is a challenge when implementing the technology, as the network needs to be able to support a large number of users.

The scalability issue comes up because as more people use blockchain, there will be more transactions that need to be processed, which means transaction fees may go up.

Thanks for sharing and good luck in this contest friend.
