Open experiment · Public testing

Mining power that money can't hoard.

Every coin spent on mining buys the same share of influence, whether you hold a little or a lot. That influence has to be renewed, so nobody stays in control just by having been ahead.

iuna runs as a candidate mainnet: it is not mainnet yet, and the protocol remains experimental. The chain is intended to carry forward if promoted, but that is not guaranteed. Run an independent node and report what you observe or where it fails.

The idea

What are we trying to change?

Many networks give lasting influence to whoever already controls the most capital or mining scale. iuna tests a different balance: open Heartbeat mining and Ledger mining weight that expires.

How capital turns into network influence

Proof of Work

Scale advantage
Proof of Work scale advantage A conceptual curve showing mining efficiency rising sharply after access to specialized ASIC scale. Capital & infrastructure → Efficiency →

Specialized hardware and operating scale can make additional investment more productive once a miner crosses the entry threshold.

Proof of Stake

Persistent capital
Proof of Stake proportional influence A straight rising line showing recurring influence and expected rewards proportional to the amount staked. Stake held → Recurring influence →

More stake brings proportionally more recurring influence and expected rewards, while the underlying stake remains owned.

iuna Proof of Expenditure

iuna expenditure effect A flat line showing that the same expenditure buys the same temporary lottery weight at every existing wallet size. Existing wallet size → Temporary weight →

The same expenditure buys the same temporary lottery weight for a small or large holder. It is paid to Heartbeat miners, expires, and must be paid again.

Temporary influence

No permanent seat at the table

Ledger mining weight is paid for again each time. Past participation does not become a permanent claim on the network.

Open entry

Heartbeats stay open

Anyone can search for SHA-256 Heartbeats. Ticket expenditure and Ledger transaction fees reward published work.

Still unproven

An experiment, not a promise

The design is public so its assumptions can be tested, challenged, and improved with evidence.

Under the hood

Two chains, one validated state

Every full node validates the Heartbeat Chain, the Ledger Chain, and their shared UTXO state.

01 · Heartbeat

Proof of Work sets the pace

SHA-256 Heartbeats target one minute, order ticket activity, and provide fresh public randomness.

02 · Ticket

Expenditure buys temporary weight

A ticket spreads its budget across a chosen active duration. The budget is streamed to Heartbeat miners.

03 · Ledger

A public lottery settles transactions

About every ten Heartbeats, the best normalized ticket output wins the next Ledger block and its reward.

Read the protocol
Building in public

A directional roadmap

Each phase expands the experiment only as participation and evidence develop.

Done · Protocol core

Build the protocol

Implement Heartbeats, Ledger settlement, expenditure tickets, persistence, and P2P validation.

Done · Operator preview

Node and wallet

Expose separate chain projections, wallet commands, mining-ticket quotes, and secure local controls.

Now · candidate mainnet

Hardening

Remove legacy protocol paths, expand adversarial tests, and run independent nodes across environments.

After evidence

Freeze the candidate

Freeze parameters only after the candidate's behavior is understood under real use.

Not scheduled

Production decision

Promote the candidate to mainnet only after security review, stable operation, and explicit launch planning.

These milestones are directional, not promises, and may change as the experiment develops.

A network is its participants

Bring a node, a question, or a way to break it.

Meet the people testing iuna, share what you observe, and help decide which evidence the candidate still needs.
