A single price index can say that a virtual economy changed, but not why. Designers need a diagnostic picture that separates creation, exchange, possession, removal and unequal experience. The source–transfer–stock–sink–cohort canvas supplies that picture. Each view answers a different question, while their connections turn scattered measurements into an explanation.
Begin with a map, not a headline
Treat the economy as a flow network. Sources create units, transfers move them between holders, stocks describe what remains, and sinks remove units. Cohorts cut across all four views to show who encounters each flow. This map prevents an average price or total balance from standing in for the whole economy.
Choose one resource and one observation window. Give the resource a stable unit, distinguish creation from exchange, and reconcile the opening stock plus sources minus sinks with the closing stock. Transfers change ownership, not the total. A mismatch marks a measurement-definition problem before it becomes a balance argument.
View one: locate every source
A source view groups created units by cause: rewards, gathering, crafting yield, grants or another explicitly defined origin. For each group, record unit count, event count and units per participating account. The distinction matters: the same total can come from many small gains or a few concentrated gains.
Read the creation rate alongside participation. If creation rises while participant count stays flat, yield per participant changed. If both rise together, reach explains more of the movement. Segmenting by location or activity can refine the diagnosis, but only after every unit follows one mutually exclusive source definition.
View two: trace transfers without double counting
A transfer view follows value between holders through trades, gifts, market exchanges or other defined handoffs. Record volume, transaction count, distinct senders and recipients, and the distribution of transfer sizes. Do not add transfer volume to supply: the same unit can move repeatedly while aggregate stock stays unchanged.
A compact matrix makes direction visible. Rows represent sender cohorts and columns recipient cohorts; each cell contains units and transaction count. Add median size and concentration beside the matrix. High volume with few counterparties describes a different economy from the same volume distributed through many reciprocal exchanges.
View three: inspect stock as a distribution
Total stock is necessary for reconciliation and weak for diagnosis. Build bands or percentiles for holdings, then report the share held by each band, the median, the upper tail and the number of zero-balance accounts. Keep inactive and active populations separate according to an explicit activity rule.
Compare snapshots with movement between bands. A stable median can hide accumulation at the top and depletion in the middle. A rising total can coexist with less spendable value for newcomers. Distribution turns the vague question “is there too much currency?” into the sharper question “where is value accumulating, and for whom?”
View four: test the sinks
A sink view classifies permanent removals by purpose and payer. Measure removed units, usage count, distinct payers, typical payment and removal as a share of sources over the same window. Keep fees, consumable costs and optional prestige expenditure separate because equal totals can reflect very different participation patterns.
Coverage is more informative than raw removal. A powerful sink used by a tiny group can offset supply numerically while leaving most participants untouched. A broad low-cost sink can affect everyday circulation without matching that total. Inspect source-to-sink balance alongside payer reach and payment distribution, never as one universal ratio.
View five: make cohorts explicit
Cohorts provide the human cross-section of the canvas. Define them using observable criteria relevant to the question: account age band, activity frequency, progression band or economic role. Apply the same definitions to sources, transfers, stocks and sinks so differences reflect experience rather than shifting labels.
For each cohort, assemble a compact row: units created, units sent and received, closing stock, units removed, participant count and per-participant values. This reveals whether one group supplies value that another retains, whether newcomers face thin circulation, or whether a removal burden falls mainly on one participation pattern.
Connect the views into a diagnosis
Read the five views as a chain. First verify stock reconciliation. Next identify which sources explain net growth. Then inspect transfers to see where created value travels, stocks to see where it rests, sinks to see where it exits, and cohorts to show who drives or absorbs each change.
Use rival explanations. Suppose holdings in the upper band rise. One explanation is concentrated creation; another is broad creation followed by upward transfers; a third is lower sink participation among established holders. Each predicts a different pattern across the five views. Prefer the explanation supported by all relevant views, not the loudest single chart.
Use a worked diagnostic pass
Consider an illustrative resource with an opening stock of 1,000, 300 units from sources and 180 removed by sinks. The reconciled closing stock is 1,120; transfer volume does not alter that arithmetic. If 600 units change hands, the transfer view describes circulation, not another 600 units of supply.
Now add cohorts. If newer participants create 180 units, send 150 and retain 30, while established participants receive most transfers and pay only a small share of sinks, aggregate growth is not the complete finding. The joined views point to directional concentration. The numbers are illustrative, not facts about World Of Arcana.
Turn the canvas into a review checklist
Before discussing a balance change, check: one stable unit; one stated window; mutually exclusive source and sink classes; transfers excluded from supply; opening and closing stocks reconciled; holdings shown as a distribution; inactive populations handled explicitly; cohort definitions held constant; and illustrative numbers labelled as examples.
World Of Arcana is publicly described as a persistent 2D MMORPG shaped by online continuity, simulation, connected geography, progression and repeated presence. Those stated qualities provide a substantive context for asking how economic state can be reasoned about across time and participants. This five-view framework is an analytical method derived from that public context; it makes no claim about unlisted features.
Conclusion: balance the explanation first
A balance decision is only as good as its diagnosis. Sources explain creation, transfers explain movement, stocks explain possession, sinks explain removal and cohorts explain unequal experience. Reconciliation keeps the views honest; rival explanations keep interpretation disciplined. Together they replace a one-number verdict with a testable account of change.
Start with a single resource and a bounded window. Build the five views, trace one change through the chain, and state which evidence supports the conclusion. That compact practice gives designers and systems engineers a clearer basis for discussion while respecting the boundary between an analytical example and the public description of World Of Arcana.
