In my opinion, blockchain is not a panacea. Blockchain cannot solve all problems. The scope of blockchain technology is actually very limited. Blockchain software solutions have very significant drawbacks - they are expensive and slow.
Because of this, it makes sense to use blockchain technology only in very important projects in which participants do not trust each other.
The ideal application of blockchain technology is the world's reserve currency (i.e. Bitcoin).
Also, blockchain technology can be used in projects related to maintaining a register of owners of shares, real estate, etc.
