I am interested in the question of security, will it be at a high level?
Blockchain technologies will provide maximum security and at the same time transparency.
What kind of security are we talking about? The blockchain technology is not yet at the perfect level, and it is simply not advisable to speak now about perfect security. There are a lot of problems in the technology itself, starting with security.
I fully agree that it is impossible to assure 100% of security. Everything changes every day. We do not know what awaits us tomorrow.
