Mempool has been launched in early 2020 as an open-source project, which is committed on building high quality data visualization “without distractions like Altcoins, advertising or third-party trackers”.
“With the help of the community we added support for 20 languages in just two weeks. This really shows the power of open source collaboration. As I currently reside in Vietnam it was natural for me to want to add support for Vietnamese for the local Bitcoin community. If you want to use mempool in your own language, just reach out and help out with the translation.” @softsimon
The project is financing itself exclusively by donations – if you want to become a sponsor can do so here.
