Bitcoin's "consensus" is people's acceptance and recognition of Bitcoin. Bitcoin is endorsed by "consensus", not by physical assets, nor by the credit of a centralized government or country. So from this point of view, Bitcoin is difficult to replicate.

The blockchain technology represented by Bitcoin naturally solves the problems of centralization and trust, making the transfer of value more convenient than ever.

The internal combustion engine solves the problem of converting explosive energy into power. The generator solves the problem of energy transmission. The problem solved by the Internet is the problem of cross-domain transmission of information. Bitcoin solves the problem of the trust of communication.
