What is Sapling?

Sapling is a network upgrade that introduces significant efficiency improvements for shielded transactions that will pave the way for broad mobile, exchange and vendor adoption of Zcash shielded addresses.


Performance for shielded addresses
Payments involving the new Sapling z-addresses can be constructed in as little as a few seconds and with only 40 megabytes of memory.
Decoupled spend authority
Allows the hardware that constructs the zero-knowledge proof to be independent from the hardware that signs for the transaction.
Improved keys
Full viewing keys allow owners of shielded addresses the ability to view incoming and outgoing transaction details without exposing their private spending key.

How do I upgrade?

Update your Zcash client to 2.0.0 or above. Nodes which haven't updated will exit with an error message requesting an update prior to the upgrade. The only way you will miss the upgrade is if you are running your own full node and manually configured your client to continue running the legacy software.
