  As the blockchain ecosystem gets more mature many businesses, investors, and
entrepreneurs are seeking opportunities on working with blockchain systems and
cryptocurrencies. A critical challenge for these actors is to identify the most
suitable environment to start or evolve their businesses. In general, the
question is to identify which countries are offering the most suitable
conditions to host their blockchain-based activities and implement their
innovative projects. The Blockchain Readiness Index (BRI) provides a numerical
metric (referred to as the blockchain readiness score) in measuring the
maturity/readiness levels of a country in adopting blockchain and
cryptocurrencies. In doing so, BRI leverages on techniques from information
retrieval to algorithmically derive an index ranking for a set of countries.
The index considers a range of indicators organized under five pillars:
Government Regulation, Research, Technology, Industry, and User Engagement. In
this paper, we further extent BRI with the capability of deriving the index -
at the country level - even in the presence of missing information for the
indicators. In doing so, we are proposing two weighting schemes namely, linear
and sigmoid weighting for refining the initial estimates for the indicator
values. A classification framework was employed to evaluate the effectiveness
of the developed techniques which yielded to a significant classification
accuracy.
