According to official sources, US$1.5 billion was recently stolen from the Bybit Exchange, and security issues in the Web3 industry have once again attracted attention. For example, there are a large number of phenomena such as phishing and account theft in Telegram, resulting in the loss of assets of a large number of users. Luffa, a recently released distributed social platform, aims to build the most secure decentralized encrypted communication platform. Luffa can avoid the above-mentioned risks such as centralized servers being compromised and personal information being leaked. Luffa is a decentralized social application built based on the Endless protocol. It uses end-to-end encryption technology and decentralized data backup. Even if customers break through the Luffa server, they cannot obtain the user's chat information. At the same time, they use mnemonic words to log in, and there is no leakage of personal information and the SMS Captcha is hijacked.
