FAQ

Q: How does PW protect users' privacy?
A: PhalaWorld can only get user data through the address connected to the PW. The address of the ID graph is not disclosed to the public. The MCP will only return the aggregated identity data authorized by the user to the PW. The address in the ID graph is privately protected.
So in general, PW has no way of knowing any user's account in DID other than the address of the user connected to PW and the data that MCP returns to PW.
The user's ID Graph is currently stored on the MCP server. MCP will not track the user's on-chain behavior, nor will it save any data other than the ID Graph. MCP is an off-chain version of Litentry aggregated identity. When the Litentry aggregated identity blockchain is developed, MCP will be switched to a decentralized version to achieve an utterly trustless privacy-preserve aggregated identity.
