Handshake is a decentralized application (dApp) that facilitates secure and verifiable chat sessions between two parties. By integrating cutting-edge blockchain technologies, Handshake offers a comprehensive solution for transparent and trustworthy online communications.

⚡️ Features

1. Secure Chat Sessions

   Handshake uses Push Protocol to enable seamless and secure chat sessions between users. Push Protocol provides reliable messaging services with end-to-end encryption, ensuring the privacy and safety of your conversations.

2. Digital Signing Handshake incorporates Sign Protocol to allow both parties to sign the chat data once the conversation is complete. This digital signature verifies the authenticity and integrity of the chat, creating a verifiable proof of the interaction.

3. Immutable Storage The signed chat data is stored using Filecoin, a decentralized storage network. Filecoin's robust infrastructure ensures that your data is safely and securely stored with redundancy and resilience, providing an immutable record of your conversations.

❓ How Handshake Works

1. Start a Chat
   • Invite another party to engage in a chat session using the Handshake platform.
   • Utilize Push Protocol's secure messaging services for encrypted communication.
2. Sign the Chat
   • Once the chat session is complete, both parties can agree to digitally sign the chat data using Sign Protocol.
   • The digital signatures ensure the authenticity and integrity of the conversation.
3. Store on Blockchain
   • After signing, the chat data is securely stored on the Filecoin network.
   • The signed chat data is now an immutable record on the blockchain, accessible for verification by both parties.
