Physical substrate layer for Plurigrid ASI — co-deployed fiber optic + geothermal infrastructure providing sensing, communication, energy, and materials extraction through a single bore.
The bore hole is the conduit. The fiber is the sensor. The heat is the energy. The observation channel and the communication channel are the same physical object.

Each physical glass-line site becomes a world in the 26-letter mesh:
# A glass-line site binds to a world wallet
class GlassLineSite:
def __init__(self, letter: str, bore_depth_m: float, fiber_count: int):
self.letter = letter
self.world_wallet = WORLD_WALLETS[letter]
self.bore_depth = bore_depth_m
self.fiber_count = fiber_count
self.dts_stream = None # MQTT topic for thermal data
def bind_to_swarm(self, mesh: HammingSwarm):
"""Physical site joins the multisig mesh"""
# The site's thermal output backs the world's DeFi position
# Geothermal energy production → staking yield analogy:
# constant baseload output, no intermittency,
# 90%+ capacity factor (like Amnis stAPT stability)
mesh.register_site(self.letter, self)
def sense(self) -> dict:
"""DTS reading from fiber"""
# Returns temperature profile along entire bore
# This IS the observation — no separate measurement needed
return self.dts_stream.latest()
Geothermal LCOE: $0.04-0.08/kWh (baseload, 90%+ capacity factor)
Grid power (US avg): $0.12/kWh
DGX Spark (3 nodes): ~6kW sustained
Annual energy cost:
Grid: 6kW × 8760h × $0.12 = $6,307/yr
Geothermal: 6kW × 8760h × $0.05 = $2,628/yr
Savings: $3,679/yr (~58%)
Cooling savings (ground loop vs HVAC):
~40% reduction in cooling energy
Additional $1,500-2,500/yr savings
Total annual savings: ~$5,000-6,000/yr
= ~700 APT/yr at current price
> 5x the entire DeFi yield (10.8 APT/yr)
The physical substrate dominates the digital yield.
| Trit | Layer | Role |
|---|---|---|
| -1 | glass-line | Physical substrate (sensing, energy, materials) |
| 0 | acsets + gay-mcp | Data model + coloring (digital structure) |
| +1 | glass-bead-game | Synthesis (emergent coordination) |
Conservation: the physical (-1) grounds the digital (0) which enables the emergent (+1).
