Zcash is the first decentralized network to use a new form of zk-SNARK cryptography for privacy. Anonymous transfers are encrypted and inaccessible in the Zcash Blockchain Explorer, but despite this, they are validated according to the network's consensus rules using "zero knowledge" proof.
Each network user, thanks to zk-SNARK, can confirm the possession of certain data (for example, a private key), without disclosing them and constantly interacting with the validator. The zk-SNARK proof algorithm compiles the hash sum of a transaction into a schema for solving algebraic equations. The quadratic asymmetric program (QAP) developed by a group of cryptographers in 2013 is used to authenticate the arithmetic scheme. QAP generates a random verification point that is not known in advance by either the sender or the validator. For this, such forms of cryptography as homomorphic encryption and elliptic curve pairing are used.
The recipient of funds creates a set of keys or a key tuple, it includes
Expense key;
view key;
Billing address.
When creating a hidden transaction, the key tuple is not available in the browser, information about these keys is provided only upon request.
The sender of a hidden transaction generates a note that includes:
Payment key;
Transfer amount (calculated in Satoshi);
Zeroing set;
Transmission trap.
The note confirms that the amount indicated in it can be spent by a recipient who has an spending key that matches the payment key. Notes created using the JoinSplit technology are stored in an incremental Merkle tree of a given depth. |

Hi! Do you know anything about Polkadot, it is a "blockchain internet" that can connect multiple blockchains, allowing them to communicate with each other. It enables independent blockchains to communicate with each other seamlessly for simple and orderly inter-chain transfers. And Polkadot manages this innovation through its parachain system.
There are only 100 Polkadot parachains in the world right now, so the competition to get parachain is fierce. If you are interested in this topic I found an excellent article on the subject. |
