RustChain Rewards Older Hardware More With Proof-of-Antiquity Consensus

RustChain is an experimental blockchain project that replaces traditional hash-rate competition with a consensus mechanism called Proof-of-Antiquity, which assigns higher mining rewards to older and rarer hardware. Under this system, a 2003 PowerBook G4 earns a 2.5x reward multiplier, while modern processors receive base or below-base rewards, and ARM single-board computers like the Raspberry Pi are heavily penalized to deter mass deployment. To prevent participants from falsely claiming older hardware, the system uses six hardware fingerprinting techniques — including clock drift patterns, cache timing signatures, and thermal noise measurements — that are difficult to replicate in virtual machines or emulators. Hardware identity is verified through composite scores derived from these physical measurements rather than self-reported data. The project, whose technical details are documented in its source code and configuration files, represents an attempt to reward hardware diversity and longevity over raw computational power.
