Inca field rotation, rebuilt as a yield protocol on Robinhood Chain
A field of 6 tokenized stocks that turns once a week.
The Inca did not manage their land. They cut it into sectors, planted the sectors in a fixed order, rested one at a time, and every household held a strip in every sector. Nobody chose, nobody timed, and the whole community lived the same season. They called the system muyuy: the turn.
Muyu is that field, over Robinhood’s tokenized stocks. 6 sectors, one stock each, in a ring whose order is graven once. One turn is five NYSE sessions. Each turn one sector is harvested, the sector harvested last turn is sown again, and the rest stand planted. One sector’s share is always at rest, in dollars, and that is where withdrawals come from.
Nothing here is managed. There is no strategy, no keeper and no pool: the field never trades. It opens a window at the Chainlink price with a rebate that climbs through the turn, and whoever finds it worth their while does the work. What a harvest brings back above what its sowing cost is paid to the holders, in dollars. The harvest is the yield.
The turn
Number the sectors around the ring. At turn t, sector t mod N is the harvest: everything it holds is offered for dollars. The sector harvested at turn t − 1 is sown: it buys its stock back with the dollars the harvest brings in. Every other sector stands planted. After N turns the ring has come all the way round.
A turn is counted in bells, not days, off the NYSE calendar that already lives on this chain. It opens at a close and ends at a close, so no turn ever ends at four in the morning on a Sunday, against the thinnest price of the week.
Because a sector is sown with the previous harvest’s basis, the field is replanted at the size it was sown. It does not compound into more land. What it grows leaves as harvest; what it loses, it loses.
a turn, in forty seconds
Five sessions on the hill.
The sun crosses five times. The farmers work only while the exchange is open, so the harvest and the sowing advance only then; at night there is a fire on the fallow. It is the same drawing the hill above is made of, run through a whole week.
The work
The field never goes to a pool. Selling a sector into thin liquidity at an hour every bot knows in advance is how a protocol pays its yield to someone else. Instead each turn opens two windows at the Chainlink print.
Harvest — buy the harvest sector’s stock from the field at the print less a rebate. Sow — sell stock to a sector below its share at the print plus the rebate. The rebate starts at zero when the turn opens and climbs in a straight line to 1% at the turn’s last bell. Whoever finds it worth their trouble first does the work first, and the field pays the least anyone will take.
The windows fill only while the exchange is open. A print held through a weekend is a standing offer to whoever knows where the market went; the farmers go home when the bell rings.
This is the mit’a: labour owed to the field, paid in kind, by turns. Anyone with a wallet can be the labour.
5 sessions a turn. The rebate is a function of the wall clock, not of who is watching: it is the same for everyone at the same second.
The harvest
Every sector remembers its basis: the dollars spent sowing what it holds. When it is harvested, the dollars that come back above the basis are the harvest, and they are paid out on the spot — in dollars, claimable, pro rata to every MUYU holder at that instant. The basis goes back to the fallow to sow the next sector.
A dividend needs no special handling. On this chain it raises the token’s Chainlink print, so it is in the harvest already. A sector harvested below its basis pays nothing; the field is simply smaller for the next sowing.
The Inca kept accounts on knotted cords. The last harvests are tied in beside this, in whole dollars, with the real encoding: tens as simple knots, units as one long knot, a lone one as a figure-eight.
Bring seed, or bring your hands.
Deposit dollars and hold a strip in every sector. Or work a window when the rebate is worth it: buy the harvest, sell into the sowing. Both are one transaction, and the field owes nothing to anyone who is not there.
