The PEAQ platform offers reliable data protection through cryptographic hashes which are cryptographically bound by using smart contracts (Peer2peer). This means that all parties can check if any changes have been made after signing off or before publishing their own transactions/data sets. It also supports multiple layers of verification such authentication via biometrics / facial recognition etc. There were no major disadvantages during my time working at PeqA so far - but we're still small compared to other providers out there! If you need robust security solutions without overdoing things this could very well fit your needs best!
