The physical layer for money
The Manhattan Project — $BUNK. Hand-crank a Verifiable Delay Function, seal a 10kb block, and settle it on-chain. No grid. No fiber. No permission.
Crank a $BUNK blockStart with the physical layer
Most chains assume the internet exists. This one doesn't. When you design for regional collapse, you build from the bottom up.
Blocks bounce off the ionosphere across borders, blackouts, and blockades. It works precisely when the internet doesn't.
A Verifiable Delay Function forces real, unfakeable time to pass between blocks — powering coin-weighted Nakamoto consensus.
No exotic parts. Assume only a base level of manufacturing — 200nm lithography and a bicycle crank. Buildable anywhere.
The killer app isn't speculation — it's dollars that keep moving when the region's infrastructure goes dark.
Live testnet
A genuine sequential-squaring VDF runs in your browser. Crank to supply the work, seal the block, then broadcast the proof — the network re-verifies it server-side and appends it to a shared, persistent chain you can watch in the explorer.
No crank, no valid proof, no block. That's the point.

Why you actually buy it
You pay for it the way you pay for insurance — a small slice of every paycheck, regardless of price. The best global utility you could ask for is everyone auto-spending 2% on a hedge against regional collapse.

“Ooh, double layer are 8.5GB. We've got ourselves a new physical layer.”
“It would only cost like $6k to bootstrap the DVDs.”
Don't sell the moon — sell a hedge against regional collapse. 2% of every paycheck, price-agnostic.
