Blockchain as a technological solution in land administration
Pauliina KRIGSHOLM,Kaisa RIDANPAA And Kirsikka RIEKKINEN
In this study examine new possibilities that the blockchain technology offers for land administration as well as barriers of implementation. Our approach was to interview experts that have proven expertise of the blockchain technology. We summarize our findings as follows: besides technical barriers, also social and legal barriers should be acknowledged when a blockchain implementation becomes topical... [more]

Recommending a terrestrial system to overcome the vulnerability of a satellite system is to swim against a powerful titide! Galileo combined with eLoran would provide a robust technology; they can even share chips. The obstacles are not technical or financial, but political.... [more]
