##  [TL；DR]
ZkSync is an <a href="/fr/price/ethereum-eth" target="_blank" class="blog_inner_link">Ethereum</a> Layer 2 scalability solution launched by Matter Labs in 2019. Its ZK-Rollup technology solution can significantly improve trading processing capabilities and ensure transaction privacy and security.

According to the latest data, there are 203 Dapps on the zkSync chain, and the TVL for Era and Lite versions is currently $760 million and $87 million, respectively.

Users can quickly search for ZK token airdrop eligibility using the Gate Web3 Wallet and participate in other ecosystem interaction projects to gain potential profits.

## Introduction
With the explosive growth of applications such as DeFi, NFT, and Game, the scalability issues faced by Ethereum have become increasingly prominent. To solve this problem, as a scalability solution for Ethereum Layer 2, zkSync has received widespread attention from the industry due to its unique technology and innovative concepts.

With zkSync officially opening airdrop checking this week and officially starting airdrops next week, zkSync has once again become a hot topic in the industry as the last coin issuance project for the four major Ethereum Layer 2 Kings. This article will briefly outline the introduction, team, technical highlights, ecosystem development, token economy model, etc. of zkSync, and focus on how to use Gate Wallet for ZK token airdrop queries, to provide readers with a comprehensive and in-depth understanding.

##  I. Introduction to zkSync
ZkSync is an Ethereum Layer 2 scalability solution launched by Matter Labs in 2019. Its mission is to bring higher transaction throughput and lower transaction costs to Ethereum by applying zero proof of knowledge (ZK-SNARKs) technology while maintaining the security and anti-censorship of funds.

The core concept of zkSync is to expand the Ethereum main chain through off-chain computing and on-chain validation, providing users with a faster, cheaper, and safer trading experience.
 
##  II.  ZkSync Team
As the parent company of zkSync, Matter Labs has raised $258 million in financing to date. It was founded by CEO Alex G. in 2018 and is headquartered in Germany. The team currently has over 50 blockchain technology experts and senior developers worldwide.

Meanwhile, zkSync has also established cooperative relationships with multiple well-known institutions and enterprises to jointly promote the development and application of blockchain technology.

##III. Technical Highlights
ZkSync is known as the end of Ethereum Layer 2 because it adopts cutting-edge ZK Rollup technology. This technical solution can significantly improve trading processing capabilities and ensure the privacy and security of transactions. In addition, zkSync also supports smooth interoperability with Ethereum smart contracts, and its modular design makes it easy to upgrade and expand.
 
### Zero Knowledge Proof (ZK SNARKs) Technology
One of the core technologies of zkSync is zero-knowledge proof (ZK-SNARKs) technology. This technology allows validators to validate the validity of transactions without knowing the specific trading content, thereby achieving privacy and scalability of transactions.

In addition, there are currently two mainstream Rollup solutions. Optimistic Rollup technology can accelerate transactions and reduce costs, but its fast and affordable features come at the cost of sacrificing some security and decentralization, which is mainly reflected in major projects such as <a href="/fr/price/optimism-op" target="_blank" class="blog_inner_link">Optimism</a>, Arbitrum, and Metis. In contrast, ZK Rollup provides trading privacy protection, excellent scalability, and relatively low costs. However, this technology also comes with relatively high complexity deployment challenges, with main project representatives including Starknet and zkSync.
 
### Off-chain Computing and On-chain Validation
ZkSync adopts off-chain computing and on-chain validation methods, placing most of the computing work off the chain to reduce the load on the Ethereum main chain. Meanwhile, through on-chain validation, ensure the effectiveness and security of transactions. This approach not only improves trading speed but also reduces trading costs.
 
### Compatibility with the Ethereum Main Chain
ZkSync is highly compatible with the Ethereum main chain, allowing users to conduct transactions on zkSync without changing wallets or addresses. It also supports the transfer and trading of ERC-20 tokens, providing users with more convenient services.
 
### Smart Contract Interoperability Support
ZkSync 2.0 (also known as zkSync Era) introduces support for Solidity (through zkEVM) and Zinc (the internal programming language of Rollup), allowing developers to easily deploy existing Ethereum smart contracts onto zkSync. This feature greatly improves the scalability and interoperability of zkSync.
 
## IV. Ecosystem Construction
Currently, zkSync has formed a relatively complete ecosystem, covering multiple fields such as wallets, exchanges, DeFi, GameFi, Social, and DAO applications.

According to data from DappRadar and Layer 2BEAT, there are 203 Dapps on the zkSync chain. Currently, the TVL for Era and Lite versions is $760 million and $87 million, respectively, while the Daily TPS is 6.12. The cost of Gas is $0.01, with 7 million on-chain addresses and over 3 million weekly active addresses.
 
##V. Token Economy Model
The native token of zkSync is ZK, with a total supply of 21 billion. The issuance and distribution of ZK tokens follow the principles of fairness, impartiality, and openness, aiming to encourage users to participate in the ecosystem construction and development of zkSync.

The allocation of ZK tokens mainly includes the following aspects: team reservation, community incentives, ecosystem cooperation, airdrop rewards, etc. Among them, community incentives are an important component of ZK token distribution, aimed at incentivizing users to participate in zkSync's community construction and operation.

According to the latest official announcement, zkSync will airdrop 3.675 billion ZK tokens to early users and contributors next week, accounting for 17.5% of the total supply of 21 billion ZK tokens. The deadline is January 3, 2025. The eligibility for airdrop is based on a snapshot taken on March 24, 2024, and eligible addresses will be allocated based on the amount sent to zkSync Era and the length of time crypto assets remain in the wallet. A total of 695,232 wallets were shortlisted, and each address requires at least one point to qualify. The project team adopts multiple methods to filter robots while adjusting allocation based on human behavior and contributions to zkSync.

Although this project is accompanied by the zkSync parent company's dispute over the zk trademark application, as well as the current high witch-rate airdrop dispute, the community is still highly enthusiastic about this project. The following text will introduce how to quickly use Gate Wallet for airdrop qualification checking.
 
Step 1: Users who are using the Gate Web3 Wallet for the first time can go to [the page](https://www.gate.io/web3 "the page") to download and install the wallet which is currently available in two types: App version and Chrome Extension version.

The Gate Web3 Wallet is an un-custodial public crypto wallet independently developed by Gate.io, serving the needs of Web3 users to trade cryptocurrencies anytime, anywhere. It can provide users with innovative and diversified crypto services such as managing crypto assets, interacting with decentralized applications, storing non-fungible token (NFT) creation, on-chain identity, and collaborating with communities.
 
Step 2: Taking the browser extension as an example, as shown in the figure, click "Add to Chrome," then create or import mnemonic phrases/private keys according to the prompts to open the wallet and switch to the zkSync Era chain.
