Can Slipstream ensure that the public key of the transaction is not leaked?

Slipstream needs to package the transaction area, which requires miners to mine, so miners can definitely obtain the public key. Is Slipstream mining using its own machine?
Does slipstream not allow others to mine to ensure that the public key of the transaction is not leaked?

Slipstream needs to package the transaction area, which requires miners to mine, so miners can definitely obtain the public key.

Mining pool typically use Stratum protocol. Stratum doesn't give raw TX, but rather block header, list of TXID and other metadata so miners can arrange and hash lots of possible block header combination at once. So there's no risk miner who join a mining pool can know raw TX (including associated public key).

Is Slipstream mining using its own machine?

It's not stated on their website[1]. But one of their news state shows other mining company joined their mining pool[2].

If Slipstream handles mining internally, it could be a design choice to protect sensitive data like the public key from exposure. But it raises a question: how is decentralization maintained if external miners aren't allowed?
