Multiplier Calculation Examples

Vintage with Time Decay

PowerPC G4 (age 24 years, base 2.5x)

decay_factor = 1.0 - (0.15 × (24 - 5) / 5.0)
             = 1.0 - (0.15 × 19 / 5.0)
             = 1.0 - 0.57 = 0.43
vintage_bonus = 2.5 - 1.0 = 1.5
final = 1.0 + (1.5 × 0.43) = 1.645x

Core 2 Duo E8400 (age 19 years, base 1.3x)

decay_factor = 1.0 - (0.15 × (19 - 5) / 5.0)
             = 1.0 - (0.15 × 14 / 5.0)
             = 1.0 - 0.42 = 0.58
vintage_bonus = 1.3 - 1.0 = 0.3
final = 1.0 + (0.3 × 0.58) = 1.174x

Modern with Loyalty Bonus

Ryzen 9 7950X (base 1.0x, 3 years uptime)

loyalty_bonus = min(0.5, 3 × 0.15) = 0.45
final = 1.0 + 0.45 = 1.45x

Ryzen 9 7950X (base 1.0x, 5+ years uptime)

loyalty_bonus = min(0.5, 5 × 0.15) = 0.5 (capped)
final = 1.0 + 0.5 = 1.5x

Server Bonus

Xeon E5-1650 v2 (Ivy Bridge, age 13 years, server)

base = 1.1x (Ivy Bridge)
with_decay = 1.0 + ((1.1 - 1.0) × (1.0 - 0.15 × 8/5)) = 1.076x
with_server = 1.076 × 1.1 = 1.1836x

Multiplier Tiers Summary

Tier Multiplier Range Hardware Examples
Mythic 3.5x - 4.0x ARM2/ARM3, VAX, Transputer, Clipper, NS32K, ROMP
Heroic 3.0x - 3.4x 68000, i386, MIPS R2000, i860/i960, 88K, Am29K, ARM7TDMI

15 30% decay 2.05x
20 45% decay 1.825x
25 60% decay 1.6x

FAQ

Q: Why does my modern Ryzen have 1.0x but can earn more? A: Modern CPUs start at 1.0x but earn +15% per year of consistent uptime (loyalty bonus), up to 1.5x after 4 years.

Q: Why is my 2012 Xeon showing 1.18x instead of 1.1x? A: Server hardware gets +10% bonus on top of base. Also, time decay reduces vintage bonuses over time.

Q: How often does the multiplier update? A: Time decay recalculates on each epoch settlement. Loyalty bonus increases annually based on attestation history.

Q: Can I game the system with VMs? A: No. The RIP-PoA fingerprint system (6 hardware checks) detects VMs and rejects them. See fingerprint_checks.py.

Q: What happens to PowerPC multipliers in 10 years? A: They decay to ~1.0x by 2030-2035, but early adopters (2024-2028) still benefit from high rewards.
