Probably in the future there will be new algorithms with their own advantages and disadvantages, and will replace those options that are known to us from the content of your article.
The consensus algorithms known to us are a compromise between scalability and the degree of centralization (although two-tier networks can achieve greater scalability within the same algorithms).
It will be very interesting to see which mechanisms will be most effective for building large-scale networks with distributed participation and stable control; Equally exciting will be the process of adapting society to the introduction of these developments.
