Introducing
SHIELD
World's first zk-SNARKs based privacy protocol on a Proof of Stake blockchain.

Complete Privacy
When You Want It
SHIELD provides complete privacy for your transactions; preserving the invisibility of transaction details from the sender to the receiver, the amount of the transaction and balances, with no preparation time or separated balances. This is accomplished through PIVX's novel customization of the zk-SNARK Sapling protocol by Electric Coin Company. As always, your full balance is available for transacting privately any time you wish.
