Blockchain PoCs are useless

Proof of concept is a realization of a certain method or idea to demonstrate its feasibility,[1] or a demonstration in principle, whose purpose is to verify that some concept or theory has the potential of being used. A proof of concept is usually small and may or may not be complete.

Blockchains -the immutable, tamper-proof and transparent records of events- are most valuable in highly regulated environments as I wrote earlier. Therefore building a Proof of Concept might be an interesting exercise for developers -and a lucrative business for some- it is useless as it does not proof anything since it will not be live in a real environment. And that real environment is the place where blockchains proof their real value. And I am not talking about whether customers will buy and against which price and in which color; in the real world your blockchain solution meets real legacy IT systems, legacy regulatory frameworks, legacy networks and legacy strategies. Only than you will have real Proof of your Concept.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
