Value transfer with simultaneous title change. The atomic unit of commerce.
Fast / IrreversibleTransactology. The study of transactions.
An exchange — a moment where two entities touch and separate changed. We study the geometry, the velocity, and the residue of value in motion.

Defining the transaction.
A transaction is the smallest indivisible unit of economic life: a discrete act in which property, attention, trust, or obligation passes from one entity to another, leaving a measurable imprint on both.
To study transactions is to study the chemistry of economies. Each exchange is a reaction — reagents combine, energy is released, and a precipitate of value remains. The reaction may be slow (a mortgage), fast (a tap-to-pay), reversible (a refund), or catalytic (a contract that produces further transactions). The science of transactology classifies these reactions, models their kinetics, and predicts their yields.

The discipline is older than its name. Mesopotamian clay tokens, Florentine double-entry, the Swiss bill of exchange, the SWIFT message — each is a notation system invented to keep faithful record of an exchange. Transactology is the formal grammar that unites them.
We treat the transaction as a four-part object: a sender, a receiver, a quantum of value, and an inscription. Remove any one and the transaction collapses into noise. Preserve all four and a market exists.

What follows is a working catalogue: types, frameworks, and the standing arithmetic of an everyday phenomenon that we have, until now, taken for granted.

Every transaction is a small claim about the future, settled in the present.
— Working axiom, transactologyA taxonomy of exchange.
Twelve canonical transaction types, arranged by velocity (rows) and reversibility (columns). Each cell is a class of exchange we instrument and observe.

Refund
A directed reversal of a prior sale. The first transaction the second cancels.

Figures are observational, drawn from instrumented exchanges across the period stated. They do not constitute financial advice or audited statements.
Currencies have been converted to USD at period-mean spot rates. Sub-cent discrepancies arise from rounding and are absorbed into the clearance line.
The ledger is read top to bottom; debits left, credits right. The double rule beneath the net line marks the final balance, per accounting convention.
