The currency has a good potential to reduce computational capacities needed for the protection of information about transactions. This is a key advantage of any currency on the basis of a zk-SNARK. However, the current drawback is that to perform the transaction you want to perform multiple calculations. The zcash for the specialists have developed a new elliptic curve JubJub, which increases the computing speed by 80% and reduces memory usage by 98% to protect information about the transaction, which in the future can provide access to mobile platforms. At the moment we have good reason to maintain optimism about the project
