- Breaking the Ledger Security Model
- ledger uses a secure element along with a regular (insecure) microcontroller which handles the display and buttons
- the integrity of this microcontroller is verified by having it send the contents of its memory to the secure element on boot
- this memory is small and contains the bootloader and firmware, ostensibly not leaving any room for malicious code
- Saleem found a way to store his exploit code in space normally used up by duplicated GCC stubs
- can fool integrity checker and steal random seed
- requires physical access to the device
- fix seems shaky
- Anatomical similarities and differences between Paxos and blockchain consensus protocols
- view PoW as leader election:
- finding a block corresponds to broadcasting an Accept message
- forks correspond to multiple leaders
- waiting for N successor blocks before accepting a new block corresponds to the second phase in a traditional consensus protocol
