Layer 2 (L2) scaling solutions aim to address scalability issues in blockchain networks. These solutions operate on the existing blockchain (layer 1) and introduce a mechanism to increase the network's capacity. They enhance the user experience by processing more transactions more quickly and efficiently, benefiting blockchain app development. zkSync (zero-knowledge Sync) is one such L2 solution. In this article, we explore how it achieves faster transactions and lower fees, and its benefits, and compare it with other scaling solutions.
Understanding zkSync
ZKSync is a zk-rollup that serves as a layer-two blockchain for Ethereum. Similar to optimistic rollups, zk-rollups aggregate transactions away from the Ethereum mainnet and provide transaction proofs to Ethereum.
It involves a process of bundling hundreds of transactions into a single batch. Ethereum authenticates and safeguards this process.

How zkSync is Different from Other L2 Solutions
Other L2 scaling solutions include optimism and Polygon.
The primary distinction between zkSync and Optimism lies in their underlying technology. zkSync uses ZK rollup technology along with zero-knowledge proofs for robust security. In ZK rollups, the group of transactions undergoes a verification process for accuracy on the Ethereum network.
Upon successful verification, the batch of transactions attains finality, similar to any typical Ethereum transaction. Cryptographic validity proofs, often called zero-knowledge proofs, make this possible.
For each set of off-chain transactions, the ZK rollup operator creates proof of validity. Once this proof is generated, it is then submitted to the Ethereum network, effectively concluding the roll-up batch. In zkSync, this submission process is facilitated through a SNARK or succinct non-interactive argument of knowledge.
Polygon and zkSync differ in their scaling approaches. Polygon offers a flexible scaling framework with options like sidechains, Supernets, and zkEVM that allow developers to tailor solutions to their needs. In contrast, zkSync prioritizes secure and efficient scaling using Zk rollup technology. The choice between the two depends on a project's specific needs and preferences.

Benefits of zkSync
Here are the benefits of zero-knowledge Sync:
Transaction Fees and Speed
zkSync offers user-friendly token payment fees that allow users to pay fees in cryptocurrencies other than Ethereum. For example, when transferring stablecoins like Tether, you can choose to pay the fee in Tether.
The L2 solution reduces the transaction fees to a fraction of a penny. It does so by utilizing ZK tech stacks like GPU prover, LLVM-based Solidity compiler, and Redshift proof system.
zkSync's design allows for unlimited computation in each block. It enables new types of dApps (decentralized applications) that can process significantly more data on-chain than was previously possible.
Additionally, it provides shorter transaction times, designed to accelerate the withdrawal process. Users can expect their withdrawn currency to reach their accounts between 10 minutes to 7 hours.
Throughput
zkSync has introduced the concept of hyperchains. These are a group of independent ZK chains that operate on the Ethereum network and are connected by fully trustless Hyperbridges. Users can create their Hyperchains with custom consensus and security is inherited from the underlying layer 1.
Nodes limit the throughput of individual Hyperchains. But, together Hyperchains can achieve unlimited total throughput for the entire zkSync ecosystem.
