Our approach to the regulatory issue
SIA faces the regulatory uncertainty in two ways
1) Through the continuous interactions with the regulatory
bodies because of its status as a supervised entity
2) By the participation in the FINSEC project
BLOCKCHAIN INNOVATION IN EUROPE
A thematic report by the European blockchain
observatory and forum
August, 21 - 2018
 FINSEC is a three years project involving 21 partners from 10 countries that aims at introduce,
implement and validate a novel reference architecture for integrated physical and cyber
security of critical financial infrastructures
 Within the project scope SIA is leader for peer-to-peer payments over blockchain
 A proactive interaction with the regulatory bodies during the requirement definition phase will
ensure the full adequacy of SIAchain in order to manage payments transaction in full
compliance with regulations and mandatory requirements
The research leading to these results has received funding from the European Union’s
Horizon 2020 Research and Innovation Programme, under Grant Agreement no 786727
