Better decisions
begin with evidence.
A global study of 517 blockchain companies. A practical framework for asking better questions.

What should an organisation know before it commits to blockchain? Whether the problem is clearly defined. What alternatives already exist. What the proposed intervention changes. And how success will be assessed.
In 2020, Naseem Naqvi and Mureed Hussain published findings from a global study of 517 blockchain projects and start-up companies in the Journal of The British Blockchain Association. Their work examines the evidence behind blockchain decisions and presents an approach that practitioners can use to structure their own enquiry.
The PCIO framework makes that enquiry concrete: Problem, Comparison, Intervention and Outcome. Alongside it, the 5A’s describe an evidence-based process: Ask, Acquire, Appraise, Apply and Assess.
For industry leaders, the value is practical: a clearer way to challenge assumptions before committing resources, compare options and decide what evidence would justify proceeding.
WHY IT MATTERS
Ask better questions before committing resources.
