4thpillar technologies (FOUR)

“In 2017, 4thtech proposed and later developed a DLT solution, which leverages trust provided by the blockchain to provide secure, immutable, instant cross-border electronic data and document exchange and eDelivery (i.e., FOURdx). The identification mechanism concept (i.e., FOURid) later followed in 2018, which can, with the help of the X.509 EU certificate standard, verify the connection between a blockchain wallet and a person. Notarization Service (i.e., FOURns) is also essential to the 4thtech ecosystem and provides unique digital document timestamp and authenticity verification.”
