Time-based reciprocity ledger

Established Alternative Game position: Modify Accumulation: Prohibits Ethical frame: Rousseauian Divisibility: Granular Uniformity: Fungible

Prototype: hOurworld, TimeBanks USA

Values every contributor's hour identically regardless of skill, with balances netting to zero so accumulation stays structurally impossible.

Structural profile

Topology view

Architecture

Game position
Modifies the game; time as unit equalizes hourly value
Value-signal richness
Single time-unit; one hour equals one hour regardless of skill
Accumulation regime
Sum of balances is zero; net accumulation impossible by design

Medium-of-Exchange Properties

Divisibility
Deliberately granular at the hour — 'one hour equals one hour' is the whole design point, not infinitely divisible.
Uniformity (Fungibility)
Fungible in the most radical sense — an hour of any skill is interchangeable with any other hour.
Durability
Not a stored value — hours are earned and spent as ledger entries, not a token held as a store of value.
Portability
Portable within the specific timebank network (hOurworld/TimeBanks USA), not convertible outside it.
Acceptability
High within its member network by design (any hour equals any hour), zero outside it.

Operation

Coordination / discovery
Bounded-trust mutual; time as common denominator
Governance & issuance
Network coordinator; member-collective governance
Scale & federation
Local typically; federation through time-bank networks

Anthropological assumptions

Default ethical orientation
Rousseauian; assumes equality of hours across persons
Accumulative drive
Drive structurally limited; net accumulation impossible
Status / recognition
Designed out through hour-equality regardless of skill
Time preference
Variable — net-zero accumulation pulls short-term, while the stated purpose of durable mutual-aid relationships pulls long-term; the mechanism itself doesn't resolve the tension.

In Practice

Track record
TimeBanks USA and hOurworld together coordinate a large number of local time-banking networks with a real, long-running (since the 1980s), if modest-scale, track record.
Governance requirements
Requires a local timebank organization (often volunteer-run or nonprofit) to coordinate membership and record hours.
Resource requirements
A ledger to track hours (many networks use free/low-cost software like hOurworld) and a coordinating organization; no capital reserve needed.
