About

This crate provides a library and API for working with Digital Bearer Certificates (DBC) on the Safe Network.

Safe Network DBCs are envisioned to be a private and fungible digital currency that utilize a distributed (and sharded) spentbook/mint rather than a blockchain.

Some key properties of these DBCs:

  • distributed mint means that it is not necessary to trust in a single mint entity
  • sharded mint means that the system scales indefinitely
  • transactions are settled immmediately
  • privacy by default. all transactions use privacy features.
  • utilizes a one-time key for each payment (aka stealth address)
  • use BLS cryptography

At present DBC ownership is single signature only. Multi-sig support is planned.

Some writeups about the technology can be found at:
