sub0 Asia 2024 - Dr. Christian Killer (Acurast)
summary
Acurast claims repurposed mobile phones with secure coprocessors beat conventional cloud servers on cost, energy and some latency-sensitive tasks: a Pixel 7A costs ~$499 versus a $3,000 Edge server, shows higher CPU marks, 50× lower monthly energy cost, and ML on device TPUs reaches 83× faster on TPUs in benchmarks. Acurast runs a heterogeneous network of 1,300 devices live, validated with a 50 million-prime execution test and upcycling examples that cut node cost toward 100× cheaper while maintaining cryptographic attestation.
