You have taken your time to share very important and valuable point s with us dear friend. I commend your work, as I have learnt some new things regarding the blockchain concept from tour work friend.
By design, blockchains are inherently resistant to modification of the data that has been recorded by means of ensuring that the hash function applied to the data results in an unpredictable output or hash.

This has well provided many benefits which includes security, and also, companies can also start accepting payments from anywhere in the world without having to worry about currency conversion rates or transaction fees.
Thanks for sharing dear friend, and goodluck in this contest.
