RH-4 is a real 8-bit processor that runs on-chain on Robinhood Chain. The CPU is synthesised from Verilog into 2,368 NAND gates, 171 flip-flops and 256 bytes of RAM, and the smart contract walks every gate, one instruction per block: it is not an emulator. RH4 is the token of the mother chip. There are no unlocks and no team allocation: 70% of the supply went to the public at launch, and 30% sits in the factory contract as a mining reserve. That reserve has no withdraw function and leaves only through tick(), one clock cycle at a time, to whoever pays the gas for that cycle. The RH-4 launchpad (rh4cpu.tech/launchpad.html) lets anyone mint their own chip: an NFT with its own program in ROM, its own token and its own mining reserve, with liquidity sealed forever in a vault contract. 1% trading fees on every chip market are split between the chip creator and an automatic buyback of RH4 that is returned to the factory reserve. Contracts are verified on Blockscout and the full source is public on GitHub.
