CHAI

CHAI is a decentralized AI chat system where all conversations are stored immutably on the Solana blockchain.

CHAI combines the power of ChatGPT with the transparency and permanence of blockchain, enabling censorship-resistant, verifiable, and optionally private chats.

🔧 How It Works

• Frontend: Web interface powered by a local model

• Backend: A Solana smart contract handles:

  • Message submission

  • Chat creation

  • Compression (optional)

• Storage: Messages are embedded in Solana transactions using 0 SOL transfers + program interaction.

💾 Message Storage

There are two storage modes:

• Uncompressed: Plain text stored directly on-chain. Fully readable on Solscan.

• Compressed: GZIP or zlib compressed. Requires client-side decompression. Longer messages allowed.

🔗 Transaction Details

• Each message costs approximately 0.000008 SOL.

• Stored via 0 SOL transfer with a custom program instruction.

• The entire message history of a chat can be verified on Solana explorers.
