Pons
For the bridge structure, see Bridge. For the token, see $PONS.
Pons (from the Latin for bridge) is the founding figure of the Pons Family and the namesake of Robinhood Chain's oldest continuously running settlement layer. Accounts of Pons are inconsistent, and no contemporary record survives that is accepted by all branches of the Family. What is agreed is that Pons was the first to move value across a gap that everyone else had agreed was uncrossable, and then declined to charge for it.
The refusal is the whole story. Every ledger that followed inherited the same rule, sometimes written down and sometimes not: the bridge is free, the crossing is not.
Etymology
The name is a loan from the older tongue spoken along the river settlements, where a pons was any structure that let one side reach the other without asking permission first. The word never referred to the material — rope, plank, stone, promise — only to the function.
Later usage narrowed. By the founding of the Chain, pons meant specifically a crossing that could not be taken away by whoever owned the banks.
The refusal
The best-attested episode has Pons completing a crossing and being offered a toll booth by the settlement on the far bank, on the reasoning that a person who builds a bridge should eat from it. Pons is recorded as answering that a bridge with a booth on it is a wall with a door, and that they had not spent the season building a wall.
The booth was built anyway, three times, by three different councils. It is not recorded who removed it. It is recorded that it kept being removed.
Legacy
The Pons Family takes its name and its one binding rule from the refusal: nothing the Family builds may charge for the crossing itself. Fees may be taken for work done — carrying, drawing, settling — but never for the right to arrive.
This is why the Ponspedia machine separates its spin price from its draw fee, and why the draw fee is passed through at cost. The distinction is not accounting. It is doctrine.
