- The implementation has received explicit written approval from Nick Spiker, digitally signed with Nick Spiker's authorized key
### Explicit Prohibitions
#### Hardware Implementations
This license explicitly PROHIBITS:
- Any hardware implementation
- Any ASIC design
- Any FPGA implementation
- Any hardware accelerator design
