Insurtech is a sector destined to revolutionize the relationship between insurer and policyholder, reformulating the entire mechanism of data sharing but maintaining, if not defining even more in detail, the security procedures. Data from the Insurtech Global Outlook report by Everis and NTT DATA say that “investors have committed 6,300 million dollars in the acquisition of Insurtech, a value that represented a 58% increase compared to the amount invested in the period 2017-2019. However, this amount was distributed among only 25 companies (out of a total of 238), which received 72% of the available financing ”. The same report estimates that the leap forward in investments in Insurtech over the next four years will amount to 21.27 billion dollars. A decisive role will be played by blockchain technology that allows you to manage a large amount of data and smart contracts, customized contracts that can be purchased directly from mobile devices that automatically execute as soon as they are activated on the basis of what has been agreed between the parties. Above all, the sector of sureties, both banking and insurance, can guarantee the process in transparency and security of the actors involved with the blockchain. A project promoted by Cetif, Sia and Reply was activated and partially concluded on this specific objective to digitize the management of bank and insurance sureties on the blockchain. After a four-month trial phase, which involved 50 operators including guarantors, guaranteed and contractors selected also from the financial world, public administration and businesses, the digital sureties project will go on the market by the end of the year. pilot, over 350 sureties were managed digitally with guaranteed amounts between € 10 thousand and € 1.4 million and an average amount of € 275 thousand. According to the data provided by the participants, who are among the main players in the management of sureties in Italy, the use of blockchain and distributed ledgers can lead to a reduction in fraud by about 30% and operating costs from 10% to over. 50%, depending on the number of transactions transacted. Among the other benefits that the participants observed, the digital sureties program will allow the reduction of costs deriving from the dematerialization of documents, greater transparency and information certainty throughout the process, greater efficiency in the management of the release of the surety and the consequent availability in reduced credit lines to be allocated to participation in new tenders.The Cetif project, a research center on technologies, innovation and financial services of the Catholic University, Sia, a company controlled by Cdp Equity and engaged in the construction of infrastructures, has been activated technologies for the financial world and Reply, a company that designs and implements solutions based on new communication channels and digital media. Together they intend to make the digital sureties platform operational and available on the market in the second half of 2021.
