What is a Sharenote?

Your Hardware is a Printing Press

Think of a Sharenote like a banknote — except instead of paper and ink, it is made of energy and math.

When you tell your hardware to print a 20Z00 Sharenote, it gets to work. It runs computations until it produces a result the network will accept as proof. That result is your note. Its denomination — 20Z00 — is stamped directly into it, proving exactly how much energy was spent to produce it.

It cannot be faked, copied, or issued for free.

Any device can verify one. From an industrial ASIC to a lightweight client. Printing at scale, however, is the job of dedicated Hashrate Providers in the market.

The Denomination is the Proof

A 10Z00 note requires less energy to print than a 34Z10 note — the same way a $10 bill represents less than a $100 bill.

But unlike printed currency, no authority decides what each denomination is worth. The denomination is a direct, mathematical record of energy spent. Higher denomination = more real work done. Always. No exceptions.

Routing scopes in the market:

DenominationExecution Scope
10Z00Processed by background AuxPoW market routing
20Z00Requires dedicated hashrate providers for strong consensus weight

Network-scale reference points:

DenominationWhat produces it
57Z54The entire Dogecoin network’s combined output in ~1 minute
78Z98The entire Bitcoin network’s combined output in ~10 minutes

The first two denominations represent common consensus targets that applications outsource to Hashrate Providers. The last two represent the aggregate output of entire mining networks — millions of machines working in parallel. The same Z-Bit scale measures everything from a feed upvote to global block formation.

Network-scale denominations reflect current difficulty and shift as each network adjusts.

What Can You Attach It To?

A Sharenote is a standalone proof. It can be attached to anything:

  • A submitted share from your mining hardware
  • A job request sent to a Data Vending Machine
  • An AI agent request that requires a specific note before executing a task
  • A social interaction like a like or view on the Nostr network
  • A message posted to a public channel
  • An article published on the open web
  • An API request from a user’s device

Whatever it is attached to, the note says the same thing: “Real energy was spent to produce this. It is not free. It is not synthetic.”
