Use Cases
How do you prove something is real on the open web?
A “like” costs nothing. A “view” can be faked. An AI can generate a million posts overnight. Sharenote attaches verifiable energy to any interaction — making it physically expensive to fake at scale.
Three distinct use cases. Each stands independently.
1. The Next Web: Build Your Own Feed
In the open social web (Nostr), there is no centralized algorithm. You are the algorithm. But in a world of infinite, zero-cost content, how do you find what matters?
A Sharenote attached to a post is a verifiable sign of energy spent. Unlike a “like” or a “view,” a Sharenote requires real computational work. Energy is the signal. It cannot be faked at scale.
Algorithmic Sovereignty
Tell your AI agent exactly how to build your feed based on specific topics and difficulty floors:
“Show me only posts about #Bitcoin that have accumulated at least
20Z00in total proof-of-work from the last 24 hours.”
Your agent verifies the math on the relay network and builds your feed based on verifiable energy commitments. A note printed by hardware simultaneously solving multiple chains counts in full — one computation, multiple valid proofs.
→ Learn how notes are printed and verified
Going deeper — Use Cases 2 and 3 are for miners and service providers. They assume familiarity with the printing press analogy from What is a Sharenote?
2. Work Templates: One Puzzle, Multiple Claims
Your hardware already solves one puzzle at full capacity. Today, that hash qualifies for one pool, one chain, one payout. Everything else it could have satisfied is discarded.
Sharenote changes the outcome: when your hardware finds a hash, every configured target is checked simultaneously. If the hash qualifies for your primary Bitcoin pool — submitted. If it also meets a secondary AuxPoW chain’s target — submitted there too. Both from one solved hash, at full hashrate, with no split.
Before: one computation, one claim. After: one computation, every qualifying claim captured.
Miners can also inject custom work into templates — such as social attestations on Nostr — that ride alongside primary mining at zero additional cost.
3. Service Providers: Energy as Payment
A service provider can require a printed Sharenote to establish consensus weight for a task. The note is the verifiable limit — unforgeable, energy-backed, separating pure noise from intentional human curation.
A user who wants the service seamlessly outsources the required denomination to a Hashrate Provider in the market, who physically solves it and returns the proof. The user includes that proof with their request. Server-side verification takes milliseconds.
This establishes a direct consensus channel between participants and the open market that operates on public infrastructure. No accounts. No hidden algorithms. The proof-of-work note is the entire consensus mechanism.
