During my research, I’ve been looking at top blockchain performers and their ability to deliver. I have reviewed their portfolio of delivered blockchain projects, checked their online presence, including profiles on social media and top rating & analytical portals such as clutch.co and goodfirms.co. I have also based this research on my past experience of working with web and mobile development companies across the globe that provided great quality and high level of communication.
