A playable economy

The Open Fork World

Bring what you can do. Find what you need. Mine it. Use it. Pass it on.

A design sandbox you can reshape and share - not a price or adoption forecast.

The little miracle

You do not need to find the one person who both wants your work and offers exactly what you want. Fork money carries value from A to B to C. The network makes more matches possible.

Live counterfactual

Watch the money find the next good thing

The common clearing

Work goes one way. Money comes back and moves again.

What people are doing for one another

The exchange river

Every line is generated from the visible world. The list is bounded to the latest eight chains.

    Why money helps

    A can help B without needing what B makes.

    A → BA gives B useful work
    B → AB pays A in fork sats
    A → CA spends those sats with C
    C → AC gives A the next useful thing

    Money separates the two halves of barter. A earns a generally spendable claim for useful work, then chooses where to spend it. Each payment becomes someone else's capacity to ask for the next useful thing.

    A fork people can enter

    Open is a design commitment.

    Open does not mean vague consensus. It means the path into shaping, inspecting, earning, and choosing the fork remains visible.

    Open code
    Anyone can inspect the rules, build an implementation, and show exactly what changed.
    Open entry
    A new miner, merchant, artist, validator, relay, builder, teacher, host, or researcher has a visible route into useful participation.
    Open configuration
    Star's world, a dated Luke / Knots proxy, and a visitor's own world can coexist without pretending one is ordained.
    Open accounting
    Issuance, fees, accumulated work, costs, balances, and who paid whom remain inspectable.
    Open future
    People may explore competing designs before launch; a network becomes real only when participants knowingly choose exact consensus rules.

    How people make money

    Every role can earn. Nobody is promised profit.

    Everyone wins is not a guaranteed payoff. A voluntary trade is mutually beneficial when the buyer values the work above the sats paid and the contributor values the sats above the cost of providing the work. A miner wins only when subsidy and fees exceed hardware and energy cost. A stalled or losing path must remain visible.

    Six cross-cutting choices

    A fork is more than its mining algorithm.

    Mining hardware matters, but a working fork also makes choices about entry, coordination, validation, money, recovery, and who can keep building when conditions change.

    PoW and hardware eligibility
    Which hardware can make eligible work, and who can realistically obtain, operate, or control it?
    DAA and bootstrap
    How do target adjustment and launch conditions behave when work arrives or leaves quickly?
    Lane and work aggregation
    If work has several lanes, how are their targets, shares, and total chain work compared?
    Mining-role, template, and payout separation
    Who owns hash, selects templates, validates work, accounts for shares, and controls payouts?
    Verifier resource bounds
    What computation, bandwidth, storage, and invalid-block work must an independent verifier safely bound?
    Activation, replay, and rollback
    How do exact rules activate, avoid replay across chains, and recover or roll back when deployment fails?

    Different starting imaginations

    Start with mechanisms. Then make a world you can defend.

    authored-preference

    Star Heartsong: Circulation Commons

    A talent-rich circulation world: easy entry, broad matching, money that moves, and mining rewards spread across more hands.

    Mechanism basis

    Star's authored invitation: open entry, broad matching, circulation, and distributed participation are values to inspect, not empirical outcomes.

    Authored world mapping
    Authored scenario mapping: higher entry, matching, circulation, and mining-spread controls make this sandbox show a circulation-first starting point. These numbers are not sourced measurements.
    Trade-off
    Broad access can leave more needs unmatched, expose miners to explicit operating costs, and make coordination visibly harder.
    Not modeled
    This authored interpretation does not establish decentralization, adoption, beneficial ownership, price, or real-world profit.

    No external source is claimed for this authored starting interpretation.

    source-informed-illustration

    Luke / Knots: ASIC-first proxy, Aug 13

    A dated, source-informed proxy for public Knots discussion: mature-ASIC security, bounded validation, and money-first policy. The current algorithm, fork specification, and rollout are unpublished. The numeric mapping is ours, not Luke's.

    Mechanism basis

    A dated proxy for public Knots and Luke Dashjr discussion. It is not a published fork algorithm, consensus specification, or rollout plan.

    Authored world mapping
    Authored scenario mapping: the numeric controls express a mature-ASIC, bounded-verification proxy for comparison. The mapping is ours, not Luke's, and is not a measurement.
    Trade-off
    Known equipment and bounded validation can still depend on fabrication, finance, hosting, firmware, energy, and coordination.
    Not modeled
    The cited discussion does not establish decentralization, a settled mechanism, beneficial ownership, deployment readiness, or launch legitimacy.

    mechanism-example

    RandomX: CPU-bound path

    An editable CPU-eligibility example based on RandomX's public design, with no claim that CPU access proves dispersed ownership.

    Mechanism basis

    RandomX documents a randomized-program, memory-intensive proof-of-work design intended for general-purpose CPUs.

    Authored world mapping
    Authored scenario mapping: this world uses broader mining spread to let a visitor inspect a CPU-eligibility hypothesis. Numeric values are authored assumptions, not RandomX performance measurements.
    Trade-off
    Commodity eligibility can coexist with cloud, botnet, energy, pool, optimized-software, and future-specialization advantages.
    Not modeled
    The RandomX design does not establish decentralization, voluntary ownership dispersion, botnet absence, adoption, or comparative miner economics.
    Sources and date boundary
    • RandomX design

      The official design describes randomized program execution and memory modes aimed at general-purpose CPUs; it does not establish ownership or decentralization outcomes.

    mechanism-example

    Grin: scheduled PoW evolution path

    An editable scheduled-evolution example inspired by Grin's public PoW transition documentation, not an implementation of Grin rules.

    Mechanism basis

    Grin's public proof-of-work documentation describes two proof-of-work tracks and a scheduled evolution in their relative treatment.

    Authored world mapping
    Authored scenario mapping: this world changes the sandbox's departure timing to teach a scheduled eligibility transition. It does not execute Grin consensus rules, and all numbers are authored assumptions.
    Trade-off
    Predictable transitions can reward specialized supply chains and impose unequal upgrade, coordination, and software-maintenance costs.
    Not modeled
    The Grin proof-of-work document does not establish decentralization, beneficial-owner dispersion, current miner participation, or the outcome of a scheduled transition.
    Sources and date boundary
    • Grin proof-of-work design

      The official document describes Grin's proof-of-work design and scheduled evolution; it does not prove a decentralization outcome.

    DigiByte: multi-work lanes path

    An editable multi-work teaching example based on DigiByte's public README; it keeps lane aggregation and common ownership visibly unresolved.

    Mechanism basis

    DigiByte's official README describes multiple mining algorithms and per-algorithm difficulty treatment.

    Authored world mapping
    Authored scenario mapping: this sandbox treats mining spread as a visible contrast while teaching that lane aggregation would require exact protocol rules. Its numeric mapping is an authored assumption, not a DigiByte measurement.
    Trade-off
    Nominal lane diversity can conceal common ownership, enable hopping, weaken a lane, and create retarget and cross-lane incentive failures.
    Not modeled
    The DigiByte README does not establish decentralization, beneficial-owner diversity, weak-lane security, aggregate fork choice, or the value of a different lane design.
    Sources and date boundary
    • DigiByte multi-algorithm README

      The official README documents multiple mining algorithms and difficulty treatment; it does not prove ownership diversity or decentralization.

    authored-neutral-start

    Open Playground

    A balanced blank canvas for changing every assumption without inheriting anyone's preferred answer.

    Mechanism basis

    A deliberately noncanonical starting canvas with no external mechanism claim.

    Authored world mapping
    Authored scenario mapping: balanced default values invite a visitor to alter every visible assumption. They are not sourced measurements.
    Trade-off
    A neutral-looking default can hide choices unless every number and its boundary remains editable and visible.
    Not modeled
    This open canvas does not establish decentralization, adoption, security, profitability, legitimacy, or a recommendation.

    No external source is claimed for this authored starting interpretation.

    Play with what people are actually discussing

    This pulse was checked on August 13, 2026. A link is an invitation to listen, not an endorsement or a complete record.

    Open the exact playground rules

    What changes

    People changes cohort size; openness changes whether work proposals enter; matching reach changes whether useful matches can be reached; circulation changes how often earned sats are spent onward; mining spread changes how many eligible miners contribute work. Currency rules fix issuance, fees, cadence, and work cost. Attacker capacity and budget change the visible scenario pressure.

    What stays honest

    This is a deterministic counterfactual playground, not a price, adoption, legitimacy, or launch forecast. Preset numbers are authored starting assumptions, not measurements.

    The scientific Agent-v2 model and its receipt remain separate in the research paper.

    What Open Fork means

    Open code
    Anyone can inspect the rules, build an implementation, and show exactly what changed.
    Open entry
    A new miner, merchant, artist, validator, relay, builder, teacher, host, or researcher has a visible route into useful participation.
    Open configuration
    Star's world, a dated Luke / Knots proxy, and a visitor's own world can coexist without pretending one is ordained.
    Open accounting
    Issuance, fees, accumulated work, costs, balances, and who paid whom remain inspectable.
    Open future
    People may explore competing designs before launch; a network becomes real only when participants knowingly choose exact consensus rules.

    How people can win

    Everyone wins is not a guaranteed payoff. A voluntary trade is mutually beneficial when the buyer values the work above the sats paid and the contributor values the sats above the cost of providing the work. A miner wins only when subsidy and fees exceed hardware and energy cost. A stalled or losing path must remain visible.
