Hi
as explained above we can not do any amendments on the block chain once the block is added to the chain, please correct me if i am wrong.
do we need servers to store data on the block chain?

Well, technically no since the entire Blockchain is holding the data as transactions and blocks. But this is just a reminder that we should take care of what we post since it can be queried on the Blockchain, even if we try to destroy the post.

Very good article.Pretty please visit my articlehttps://steemit.com/photo/@fenykia/siamese-fighting-fish
