Edit 001 · 3/22 — The Availability Carrier

Snowmoon, ch. 19: The librarian leads them to a terminal and plugs in a data cable. What comes back is an archive no single machine ever held — reassembled, whole, from pieces scattered across a network that only ever promised enough of them would survive.

Ethereum's world computer depends on a related shift. Data can be distributed across a network while validators sample its availability without downloading every byte. But evidence that data was available at one moment isn't a guarantee it can be reconstructed forever.

The Availability Carrier imagines that missing service. Recovery becomes something demonstrable: what was committed, what remains accessible, and whether the original can actually be reconstructed.

A custody roster proves neither possession nor service. Sampling provides evidence under defined assumptions, not a permanent archive. Only a verified reconstruction earns the word recovered.

Availability as a product: not where the copies are, but proof the data can come back.
