Fedi, the global Bitcoin adoption technology

It comes, however, from this:

> The final part of Fedimint is the use of two powerful technologies, federations and chaumian e-cash mints, to remove any single weak point and to maintain complete privacy for all users, and is the reason behind Fedimint’s unusual name. A federation is a mechanism that shares custody of the group’s bitcoin amongst all guardians. This ensures that a majority of guardians need to act to perform a transaction and that a failure of a minority of guardians can be tolerated by the system without affecting its operation. Chaumian e-cash mints are a cryptographic tool to allow the federation guardians to process transactions on behalf of any member of the group without knowing who it is or how much they have. This ensures financial privacy even though group members have delegated the complicated task of managing their bitcoin holdings to the guardians.
