POC can be used as an initial design while creating a Blockchain application to determine how easily it can be implemented and what objectives are practical. POC can be used as an initial design while creating a Blockchain application to determine how easily it can be implemented and what objectives are practical. Understanding a business challenge is important in creating a blockchain proof of concept. The problem that can be tended to or solved by blockchain should be the focus of the POC. The objective should be to create something little rather than an extensive POC because if it fails, there won't be much to lose. Because blockchain technology is still developing therefore knowing what can be accomplished is essential. The expectations should be absolutely clear while designing a POC.
