ZEROGRAVITY NEWS

ZHChain FURTHER DEVELOPMENT NEWS By the general vote of DAO ZHCash, a new development model and a new concept for 2023-2025 were adopted. Implementation of a new DAO digitalization model, a new staking model, bounty and airdrop programs based on new smart contracts. This allows us to take full advantage of our blockchain technology to spread the idea of ZHCash, scale, secure and monetize. The DAO smart contract allows you to receive dividends in USDT from the profits of the Zero Gravity Foundation and contributes to the growth of the price and liquidity of the ZHC. 1) the launch of a new algorithm for collective decentralized PoS mining, the Offline PoS algorithm, now ZHC PoS mining will be available to mobile device users (launch April-May 2023). 2) the smart contract will be responsible for the digitalization of the DAO, the distribution of the profits of the Zero Gravity Foundation in USDT due to the ZHC hold + decentralized voting on the blockchain (launch May-June 2023). 3) the smart contract will be responsible for staking using the IPoS algorithm and the affiliate program in the web console (launch April-May 2023). 4) the smart contract will be responsible for fully decentralized staking and will be used both for staking transactions and for rewards under the new Bounty and Airdrop programs (launching April-May 2023). 5) the smart contract will be responsible for bridges (WRAPPED ZHC) to all TOP blockchains (ETH, BSC, etc.) and will provide a prompt opportunity to enter external markets, decentralized exchanges and significantly contribute to the popularization of ZHC (launch June-August 2023) . 6) DEFI smart contract - common liquidity pool (launch May-June 2023). 7) access to additional exchanges, creation of liquidity, entry to coinmarketcap (2023). BREAKING NEWS! Soon ZHCash in Metamask! Soon ZHCash in Web3 NFT Market! Soon ZHChash in Wallet Connect! New white paper and roadmap 2023-2025 P.S. Huge development work has already been done, the model will be launched in stages over about 5-6 months.

Our infrastructure was hacked last weekend. Dozens of ZHChain Network infrastructure servers around the world have been attacked. One thing is clear: an attack, even a successful one, requires clear and quick action. Our team has taken all necessary measures to protect the systems. Leak codes, data did not happen. The maximum that could be done was to stop the work of some services for a few days. We continue to work on recovery, thanks to a well-organized data backup system. The attacks began on February 1, 2023, many users complained about problems with the availability of infrastructure sites or individual services. Coinciding with the targeted attack on the ZHChain Network and Zero Gravity Foundation servers, there was another large-scale hacker attack on a planetary scale, which was aimed at exploiting a vulnerability in certain software. Thousands of computer systems around the world have been targeted to certain types of systems. Malefactors attack software products for virtualization. Our team has fixed all vulnerabilities that cause system failure, as well as an information disclosure vulnerability that can be used to access sensitive data. We have decided to publish news about technical work in order to avoid panic. During this time, we have transferred the entire server infrastructure to more advanced technologies. Thanks to the perfect technologies and complex (cold) storage methods from the Zer0Lab development team, your data and crypto-assets are not affected. For us, this is a great and interesting experience. In the near future, we will publish a lot of good news in the development of ZHChain. The hacker attack did not affect the blockchain itself, since the network is 100% decentralized and works on the principle of peer-to-peer technologies. Best regards, Zer0Lab & ZeroGravity team.
