MobileCoin Fog: a cloud you can't see through
summary
MobileCoin Fog is a deployed system that uses Intel SGX enclaves plus an Oblivious RAM backend to let mobile wallets download only their own transactions without leaking queries. The team loads the chain into ORAM, runs Fog ingest and Fog View, and achieves about 100 oblivious requests per second per machine while serving millions of users. A new sequential stealth addresses scheme reduces O(n^2) scanning to O(n), and responses are constant‑size and indistinguishable whether a check hits or misses.
