The Gift Economy
Before markets, there was the gift. Marcel Mauss observed that gift-giving creates obligation -- the transaction is not complete at the moment of exchange but extends infinitely forward in social debt. The gift economy is not the absence of transaction but its most complex form.
Barter Limits
The double coincidence of wants: I have wheat, you have fish. But what if you want wool? Barter's limitation sparked the invention of money -- an intermediary that decouples the two halves of every transaction.
"Every transaction is a story with two authors."
Invisible Hands
Adam Smith's metaphor endures because it captures a truth transactology formalizes: individual transactions aggregate into systemic patterns no participant intended. The market is an emergent author.
"Is exploitation a transaction or its absence?"
Smart Contracts
A contract that executes itself upon fulfillment of conditions. The transaction becomes autonomous -- no intermediary, no judge, no appeal. The smart contract is the most radical experiment in transaction design since double-entry bookkeeping. Its promise: perfect enforcement. Its risk: perfect rigidity.
Attention Economy
In digital networks, attention is the scarce resource. Every scroll, every click is a micro-transaction of attention. Transactology asks: who profits from these exchanges, and what is lost?
Currency symbols: the punctuation of transaction.
Trust Architectures
Every transaction rests on trust. Transactology maps the architectures of trust: institutional (banks), mathematical (blockchains), social (reputation), and relational (family). Each architecture enables different transactions.
