Can I patent an application of a popular technology?
Let's say Blockchain is a very popular technology nowadays and there are hundreds of applications proposed and ongoing in many different domains like in, finance and medical sectors. Now, when I come across a new idea of a particular application of the Blockchain technology like, resolving an existing problem (never been addressed for distributed solution) with a distributed system using Blockchain where several solutions might exist for centralized system.
Can my idea be patented reasonably?
NB: I am new in this site, please correct me if my question is not addressed properly. I will modify it.
