DogeOS uses CubeSigner’s Programmable Policy Engine to verify that only properly attested validator nodes can sign transactions allowing users to withdraw funds from DogeOS. These custom policies give DogeOS strong guarantees that only software they wrote has signing privileges—that is, every withdrawal signature used in the DogeOS multi-sig originates from a DogeOS-owned Nitro Enclave running the expected CubeSigner software. The result is a signing workflow that’s resistant to node compromise and other common bridge attacks.
“CubeSigner gives DogeOS a secure bridge layer by ensuring only our own verified enclave code can sign withdrawals. It’s a critical safeguard against node compromise and the kind of exploits that plague other ecosystems."
