What in the world is Zero Knowledge? Let txSync explain

Ines Isljami

Ever heard of zero-knowledge? It’s a really big thing in the world of technology, especially blockchain technology. And yes, we see the paradox, but let's explain.

Zero-knowledge proofs (ZKPs) is a technology gaining a lot of buzz in various fields, particularly blockchain.

Imagine this. Two people. We’d call them A and B. A is who we’d call a Prover, while B is the verifier.

The Prover can demonstrate to the verifier that a statement is accurate without providing information regarding the statement. This is done by providing proof, or a small amount of information, that can be verified by the verifier to ensure that the statement is true.

The concept of ZKPs was first introduced in a 1985 paper titled “The Knowledge Complexity of interactive proof systems” by Shafi Goldwasser, Silvio Micali, and Charles Rackoff.

The paper defined zero-knowledge protocol as “a method by which one party (the prover) can prove to another party (the verifier) that something is true, without revealing any information apart from the fact that this specific statement is true.”

zkSync, for instance, uses an off-chain prover, which generates a cryptographic proof called a SNARK (Succinct Non-interactive Argument of Knowledge) that proves the transactions are valid. zkSync is a Layer-2 scaling solution built on the Ethereum blockchain, using zero-knowledge technology. The Ethereum blockchain, which is a Layer 1, had a lot of activity, causing slow transactions and high gas fees.

Layer 2 solutions, such as zkSync, move most of this activity away from Layer-1s, offering faster transactions and cheaper gas fees while inheriting its security. ZK Rollups are the most secure of all the scaling solutions, relying purely on math to fully inherit the security of L1, which is critical to function in highly unstable environments.

Other scaling solutions rely on economic guarantees or third parties and, as a result, offer far weaker security properties. zkSync architecture also includes zkPorter – a decentralized storage option with reduced security but much lower costs. Their mission is to increase Ethereum’s throughput and fully preserve its foundational values – freedom, self-sovereignty, decentralization – at scale.

Following these three zkSync ideology concepts: freedom, self-sovereignty, and decentralization, txSync was created.

Meet txSync!

txSync is a platform, a knowledge base powered by TxFusion, for everyone who wants to learn, create and build on zkSync. Wherever you are on your zkSync journey—an enthusiast venturing into the crypto space or an experienced developer looking to dive deeper— txSync has you covered.

txSync’s goal is enhancing accessibility and usability for everyone interested in zkSync, and it has taken a huge step towards achieving that by including the official zkSync portal (now named txPortal) and official zkSync bridge (now named txBridge) into the platform.

txPortal enables you to manage your digital assets efficiently across zkSync networks, providing all the necessary tools for working with the zkSync era. You can connect, view, and take control of your digital assets with great ease.

txBridge allows you to easily transfer funds between Ethereum and zkSync Networks while providing faster, cheaper, and more efficient transactions. All without compromising on security through its use of zkEVM (Zero Knowledge Ethereum Virtual Machine)

txLearn offers useful resources, tutorials, and documentation to guide any user, with links to websites, tools, and additional educational resources.

This platform is extremely user-friendly and easy to navigate, and with more upgrades in the future, txSync is sure to stand out as an innovation in the Web3 space!
