Hasn't it been settled already that blockchain is mostly a solution looking for a problem? The central problem of blockchain is how to incentivize participation. Without adequate participation, security is suspect. If a central authority funds participation, it is not really de-centralized is it? Back to square one --- why blockchain when simpler, cheaper "centralized" solutions are available? The only practical way to fund a truly "de-centralized" blockchain is by inventing money --- crypto.
