Privacy preserving transactions
The implementation of zero-knowledge protocols and private transactions into xDai is a major key point of the roadmap. Since xDai is a stable token, the primary use of the chain is peer-to-peer payments. Just as with cash, privacy should be an option when exchanging money or paying vendors for services. It doesn’t matter if you are sending money to a relative or your local butcher. You should have the freedom to choose for any transaction to remain anonymous.
This is why we have invested in different approaches to implement different ZK protocols into xDai based applications and wallets.
** Multi Collateral Dai xDai Bridge**
Once Dai protocol implementation will be upgraded to MCD (Multi Collateral Dai), the xDai bridge will be upgraded to use MCD Dai.
