Before joining a Proof-of-Antiquity network, establish three separate things: the machine’s exact identity, the dated records that support its history, and whether the network currently accepts its hardware. For RustChain, a vintage model and a plausible age are not enough: its protocol describes recent hardware attestation and a separate eligibility check. Neither those checks nor a signed record automatically proves when the computer was made or who has owned it.
How do I identify my computer’s exact model and processor?
Start with the identifiers for the computer as it is now, rather than relying on a case label or seller description. Record the manufacturer, exact model identifier, CPU family and architecture, and any serial or device identifiers that the operating system or firmware exposes. Photograph the computer, its labels and ports, and keep the unredacted identifiers private unless the network explains why it needs them.
Compare those details with the manufacturer’s specifications or archived product documentation and the network’s current supported-hardware information. RustChain’s draft provenance specification proposes a hardware ID built from model, architecture, family, CPU serial, device ID, and sorted MAC addresses; it also says relevant hardware changes can alter that ID. That is a proposed scheme in a draft, not a universal practice for Proof-of-Antiquity networks. RustChain RIP-0310
What records show when this device was bought or repaired?
Collect records that have dates and identify the machine or its components. Useful evidence may include an original receipt or invoice, warranty and service records, dated photographs, prior-owner documentation, and visible serial or date labels. Preserve originals and note gaps; do not infer the age of the whole computer from the date of a replacement part.

- Manufacture date: when the machine or component was produced, if a reliable record identifies it.
- Purchase date: when a buyer acquired it, supported by a receipt or invoice.
- First-known ownership: the earliest ownership date supported by records, which may be later than manufacture or purchase.
- Your possession: when you acquired it and any subsequent periods out of your possession.
- Repair and replacement history: dated work and major component changes, especially CPU or network-interface replacements.
These dates answer different questions. A dated invoice can support a purchase claim; it does not by itself prove the production date, uninterrupted ownership, or that the machine still contains its original components.
Does the network verify age, physical hardware, or both?
Ask what the network actually checks and what its result means. RustChain’s protocol describes collecting hardware signals, submitting a signed attestation payload, validating its fields and fingerprints, and checking eligibility for epoch enrollment. Its stated checks include clock drift and oscillator variance, cache timing, SIMD identity and timing, thermal entropy and load response, instruction-path jitter, and anti-emulation heuristics. It also describes sanity checks, challenge and timestamp consistency, identity formatting, anti-abuse limits, and comparisons between claimed architecture and measured behavior. These are RustChain’s descriptions of its design, not independent proof that the checks reliably defeat spoofing. RustChain Protocol Specification

RustChain’s homepage additionally describes ROM and fleet-clustering checks and VM/emulator detection. Its protocol is more qualified: “The goal is not perfect certainty; the goal is to make spoofing expensive and brittle.” Treat the attestation as evidence about measured hardware behavior during a recent check—not as a birth certificate, a complete repair log, or proof of custody across time.

The project’s draft provenance specification makes a related distinction: a signature or hash can support a cryptographic statement about what was signed or anchored, while the real-world claim the record refers to remains empirical and probabilistic. The draft explicitly does not establish absolute hardware identity or continuous custody, and says its production binding generator and verifier are not released in that document. Do not describe a signed or blockchain-anchored age claim as proven unless the record’s issuer and scope support that exact conclusion. RustChain RIP-0310

Hardware attestation can also have a narrower purpose unrelated to age. For example, Apple describes Private Cloud Compute attestation as allowing a user device to compare key ownership and software measurements against a public append-only ledger of software releases. That is about software state and node trust, not the historical age or ownership of an old computer. Apple: Private Cloud Compute Automata likewise describes attestation as a point-in-time signal whose meaning depends on issuer, scope, and freshness; it is general context, not evidence of RustChain features.

Will this model qualify for RustChain?
Eligibility is network policy, not a conclusion you can draw from a computer’s age alone. RustChain’s homepage lists hardware classes and multipliers, but its protocol describes validation and epoch eligibility as additional steps. Check the project’s current rules and the outcome for the actual device before buying, installing software, or assuming it will be enrolled. RustChain RustChain Protocol Specification

RustChain’s homepage, accessed October 4, 2026, also lists “+5% per year of tenure, capped at +50% after 10 years” and “1.5 RTC per 10-minute epoch.” These are changeable network and economic statements, not guaranteed payouts or independent valuations. Verify the current policy and distinguish a published multiplier from any estimate of what a participant will receive. RustChain

What should I check before installing or enrolling?
- Document the machine. Record its exact model and architecture, photograph visible markings, and collect dated purchase, ownership, service, and replacement records. Keep serial numbers private unless disclosure is necessary.
- Check the live eligibility path. Compare the model with RustChain’s current hardware information, then follow only current attestation and miner instructions from the official project channel. The homepage describes pip/npm installation paths and a manual legacy PowerPC route; installation steps can change, so consult the current instructions rather than relying on an old guide. RustChain
- Understand identifiers and freshness. Ask what hardware and network identifiers leave the device, how long an attestation remains valid, and what happens after a CPU or network-interface replacement. RustChain’s draft discusses a proposed binding certificate with a TTL, but that draft should not be treated as settled user policy. RustChain RIP-0310
- Keep and inspect the result. Save the attestation output and check that an accepted device appears in the network’s current miner or epoch interface. RustChain’s protocol documents public miner and epoch API calls; consult the protocol for current endpoints and response details. RustChain Protocol Specification
- Resolve failure before spending more. If a device is rejected, ask which check or eligibility rule failed, how to inspect the submitted report, and whether there is an appeal or re-attestation path. Do not assume that a model name, old label, or multiplier listing overrides a failed validation.
A PowerBook G4 is one example RustChain lists, but a used vintage computer is a separate purchase decision: condition, repairability, parts availability, and cost matter, and current eligibility must still be confirmed. A listed multiplier is not a reason on its own to buy hardware or a promise of income.
