Proof of Concept (PoC)
POC is documented evidence that a potential product or service can be successful. Developing a POC can help the person or organisation behind the product identify potential technical and logistical issues that can hinder success. It basically gives you all the proof needed that the product is good to go.
POC provides the opportunity for an organisation or individual to gather feedback about a product or service the organisation or individual firmly believes in. In other words, it gives the chance to those reviewing your product to assess it in the early days before you go public on blockchain.
