透明度、安全性和去中心化：FTX 丑闻之后

Since 2022, against the backdrop of the slowing economic growth, rising inflation and hiking interest rates around the world, the cryptocurrency sector has been in a bear market. November is the season when the weather in major countries in Asia, Europe and North America turns cool and gradually enters winter, and the recent FTX scandal has brought the whole industry straight into a blizzard. In this article, we will not dig into the specific causes of this incident, nor will we discuss the illegal practices of SBF or Alameda Research. People trust CEX and deposit their funds at CEX for safekeeping and trading, so the fact that FTX Exchange was able to misappropriate tens of billions of user assets alone is shocking and disturbing to the entire industry.

Let’s get back to the essence of cryptocurrencies and the industry’s original purpose – decentralization. The cryptocurrencies we hold (represented by BTC and ETH) represent freedom and the sanctity of personal assets, and the first thing to be guaranteed is security. Choosing a centralized exchange (CEX) for asset storage is very insecure (equivalent to authorizing others to keep one’s assets). As many mainstream tokens are issued on the ETH public chain (ERC20 protocol), ETH Wallet becomes the first choice for users to leave CEX.

ZKSpace, as a Layer 2 solution for the ETH mainnet based on ZK-Rollups technology, provides a Layer 2 wallet for users’ ERC20 assets, which are kept in smart contracts on the ETH mainnet and cannot be taken out by anyone except the private key holder. ZKSpace allows users to conduct decentralized transactions, transfers, minting or buying and selling NFTs on the ZKSpace platform, enjoying a gas fee that is much lower than the ETH mainnet and faster transaction confirmation (only a few seconds). And of course, users can withdraw their assets to their Ethereum mainnet wallet at any time they want. At the same time, ZKSpace ensures the consistency of Layer 2 and Layer 1 status by continuously generating zero-knowledge proofs, and periodically synchronizing the aggregated and packaged transaction data to the ETH mainnet, ensuring the same transaction security as the base layer. At the same time, we also provide a ZKSpace Explorer for users to freely view all addresses and transaction information of Layer 2, making it secure, transparent and decentralized.

ZKSpace team has been deeply engaged in Layer 2 scaling for several years, and has launched ZKSwap V1, ZKSwap V2, ZKSpace, covering a series of blockchain products such as Layer 2 wallet, exchange, NFT platform, domain name service, etc., with the goal of building a complete Layer 2 ecosystem. All of our smart contracts have been audited by top tier security agencies such as SlowMist and Certik, and have been running smoothly for nearly two years without any security accidents, with its peak TVL reaching $2.5 billion. We have never stopped our research and development. We remain true to our original aspiration and are committed to providing users with safe and convenient blockchain services. We invite community supervision.

ZKSpace is currently running a World Cup NFT prediction game, buy the NFT of your favorite team and you can share a large prize pool: https://zks.app/activities/WorldCup. Before the end of this year, we will also carry out Christmas activities, design exclusive Christmas NFTs for users, and reward the community. Please stay tuned!

About ZKSpace

The ZKSpace (formerly ZKSwap) platform consists of three main parts: ZKSwap, the first Layer 2 AMM DEX utilizing ZK-Rollups technology, payment service ZKSquare supporting fast and cheap Batch Transfer, and an NFT minting center and marketplace ZKSea. ZKSpace has been running since February 2021 with hundreds of function iterations, and no security incidents have ever occurred. With innovative NFT L1-L2 transfer, unlimited token listing, cheap and smooth deposit & withdrawal, and a Layer 2 domain name system ZNS, ZKSpace aims to implement EVM-compatible ZK-Rollups and bring the community more Layer 2-based products.

2022年以来，在全球经济增速放缓、通胀上升、利率上行的背景下，加密货币板块进入熊市。11月是亚洲、欧洲和北美主要国家天气转凉并逐渐进入冬季的季节，而最近的FTX丑闻更是让整个行业直接陷入了暴风雪之中。在本文中，我们不会深究此事件的具体原因，也不会讨论 SBF 或 Alameda Research 的非法做法。人们信任CEX，将资金存放在CEX进行保管和交易，FTX交易所光是挪用用户上百亿资产的事实，就足以让整个行业震惊和不安。

让我们回到加密货币的本质和行业的初衷——去中心化。我们持有的加密货币（以BTC和ETH为代表）代表着自由和个人资产的神圣性，首先要保证的是安全。选择中心化交易所（CEX）进行资产存储是非常不安全的（相当于授权他人保管自己的资产）。由于众多主流代币均在ETH公链（ERC20协议）上发行，ETH钱包成为用户离开CEX的首选。

ZKSpace作为基于ZK-Rollups技术的ETH主网二层解决方案，为用户的ERC20资产提供二层钱包，这些资产保存在ETH主网的智能合约中，除私钥外，任何人都无法取出持有者。ZKSpace允许用户在ZKSpace平台上进行去中心化交易、转账、铸造或买卖NFT，享受远低于ETH主网的gas费和更快的交易确认（仅几秒）。当然，用户可以随时将他们的资产提取到他们的以太坊主网钱包中。同时，ZKSpace通过不断生成零知识证明，周期性将聚合打包的交易数据同步到ETH主网，保证Layer 2和Layer 1状态的一致性，确保与基础层相同的交易安全性。同时，我们还提供了ZKSpace Explorer供用户自由查看Layer 2的所有地址和交易信息，安全、透明、去中心化。

ZKSpace团队深耕Layer 2扩容数年，先后推出ZKSwap V1、ZKSwap V2、ZKSpace，涵盖Layer 2钱包、交易所、NFT平台、域名服务等一系列区块链产品，拥有构建完整的 Layer 2 生态系统的目标。我们所有的智能合约都通过了慢雾、Certik等顶级安全机构的审计，近两年来一直平稳运行，没有发生任何安全事故，最高TVL达到25亿美元。我们从未停止过研发。我们不忘初心，致力于为用户提供安全便捷的区块链服务。我们邀请社区监督。

ZKSpace目前正在运行世界杯NFT预测赛，购买你喜欢的球队的NFT，即可瓜分丰厚奖池：https ://zks.app/activities/WorldCup 。今年年底前，我们还将开展圣诞活动，为用户设计专属的圣诞NFT，回馈社区。敬请期待！
