  This paper proposes an architecture and a protocol suite for a permissioned
blockchain for a local IoT network. The architecture is based on a sealed
Sequencer and a Fog Server running (post-quantum) Guy Fawkes protocols. The
blocks of the blockchain are stored in networked Content Addressable Storage
alongside any user data and validity proofs. We maintain that a typical IoT
device can, despite its resource limitations, use our blockchain protocols
directly, without a trusted intermediary. This includes posting and monitoring
transactions as well as off-chain (post-quantum) emergency communications
without an explicit public key. Keywords: blockchain, Guy Fawkes protocol,
post-quantum, HORS-OTS, LoRa, concurrent transmission
