General

Q: How does PW protect users' privacy?

A: PhalaWorld can only access user data via the address connected, while ID graph addresses remain undisclosed to the public. The MCP exclusively returns user-authorized, aggregated identity data to PW, with ID graph addresses being privately safeguarded.

In essence, PW has no means of knowing a user's DID account beyond the connected address and data returned by MCP.

The user's ID graph is currently stored on MCP servers. MCP does not monitor user on-chain activity or store data other than the ID graph. It serves as an off-chain version of Litentry's aggregated identity. Once the Litentry aggregated identity blockchain gets developed, MCP will transition to a decentralized model, achieving a truly trustless, privacy-preserving aggregated identity.

Linking to a specific platform is not obligatory; users should connect when they feel it's secure. If there are concerns about exposure during the account linking process, users can promptly remove any relevant information on platforms like Twitter or Discord following the post.

Q: Where can I buy $PHA and which wallet would I need to transfer to?

A: You can buy $PHA on Kraken (0.07 $PHA transaction costs) or Kucoin (10 $PHA transaction costs) and transfer the $PHA token to Phala Network.
