How will Blockchain Technology become more efficient?

Privacy is believed to be an inherent feature of all blockchain systems, and it was considered difficult for people to associate their online identities with offline identities. However, hackers, law enforcement, and data scientists have proven that offline identities can be related to activities on the blockchain and that it is pretty easy to do. With this awareness, newer blockchains on the market are prioritizing strengthening the privacy of blockchain networks. In this article, we will look at innovation in the blockchain that maintains user privacy and a blockchain project built around user privacy.

ZK-Snarks Introduction

The ZK-Snarks protocol was first used on the ZCash blockchain. ZK-Snarks is not a novelty and first appeared in the public domain in 1988. In summary, ZK-Snarks is a way to reduce the amount of interaction needed between an authenticator and an authenticator to verify that each has a validator in a network. Information or data they say they do. Let’s look deeper at the ZK-Snarks protocol and see how this is possible.

An In-Depth Look at ZK-Snarks

ZK-Snarks stands for Zero-Knowledge Short and Non-Interactive Knowledge Argument. It is a cryptographic method that allows one party to prove to the other party that he has the information he says he has without revealing it to the other party. A private key must be created before this operation can take place. Let’s take a look at the different parts of the ZK-Snarks protocol.


The basic concept of the ZK-Snarks protocol is that one party can prove to the other party that it has specific information. The party that tries to prove that he has the information he says he knows is called the prover, and the verifier contacts the party he tries to prove. However, data security is strengthened by establishing that one party has specific information to another that can take place without disclosing the information; This is what makes the protocol Zero-Knowledge. A party knows and knows what the report contains. The verifier can verify that the party has the data without seeing it or knowing what is in the information.


Another essential feature of ZK-Snarks is that the size of messages is “short” or insignificant compared to processing. This makes the messages in the ZK-Snarks protocol easily verifiable and reduces the data validation time to a few milliseconds. No matter how extensive the processing load, the lengths of proofs in the network are small in bytes.


Authenticators and validators in a network implementing the ZK-Snarks protocol have little, sometimes no, interaction with each other. This makes the protocol non-interactive.


Finally, the arguments are computational limits set in the validators to prevent them from sending false information like transactions to the validators.

To summarize

The privacy of legacy blockchains like Bitcoin and Ethereum has proven not to be as strong as many hoped and believed. This has led to research methods for improving user privacy on blockchains of newer blockchains. While not new to the world, one protocol has shown much potential to strengthen user privacy in a blockchain network and is called the ZK-Snarks protocol. ZK-Snarks, whose first successful application in blockchain technology is in ZCash, allows nodes in the network to prove that they hold certain information during verification without revealing the information to the other node.

Posschain Prioritizes User Privacy

Posschain is a blockchain ecosystem that connects private and public blockchains. One of the main benefits of joining their ecosystem is that blockchains can enjoy improvements in user privacy. Posschain combines the ZK-Snarks protocol with transaction mixers that break the connection between an input and output transaction, giving users back their privacy.
