Been using Presearch for a while on mobile and desktop devices and seems pretty good alternative to duckduckgo. Works fast and gives relevant results. Here is a project - https://www.presearch.io/.

Their goal: "The vision is to create totally open and transparent algorithms that leverage blockchain technology and the human power of the Presearch community so that, similar to Wikipedia, anyone can participate in the creation and curation of the search index, providing superior results and censorship-resistance."

Here is a tutorial about setting presearch as a default search engine in Brave and Chrome - https://render3d.medium.com/manually-installing-presearch-as-the-default-search-engine-on-brave-or-chrome-browsers-404f1825c82f
