Two Roots Instead Of One 🌳
Every confidential AI setup built so far has rested on a single root, which is a sealed area on the processor you have to trust to hold the keys.

$SOL that same shape turns up wherever an app sends work to hardware it does not own, because one broken component takes everything standing behind it at once.
Blackthorn splits the job between two roots that do not depend on each other. The card runs the model inside a walled region nothing outside the GPU package can read. A set of independent parties holds the keys to that region, and no single one of them can put a key back together.
Neither root covers for the other. The machine running the card never holds a key, and the parties holding the shares never see the work.
That split is also why the attacks published against sealed processors do not reach this, since there is no processor enclave left in the chain for them to land on.
Arcium settles the result on Solana as an ordinary public transaction, so the app calling the model behaves as it always did.
One root is a single point of failure wearing a security label. Two that do not overlap is a different claim.
