Abstract
SEMATECT is a protocol in which miners are represented as insects on one public hex nest that does not reset. They are not drawn as insects on the camera. Each unit is a marked worker on a hex map. A shop or patron hires a hex with a required STCT stamp. Optional bait may sit in a second pile. The first miner who submits a valid forage certificate — not the first click — receives 95% of the remaining stamp, 95% of construction bait, and a claim (“I built this”). The work-order poster receives the storefront. This paper keeps the Proof-of-Forage mathematics and library of v5.5.1 / v5.4.1 and records every rule designed after that date.
Hexes are unlimited. STCT mint is not. The subsidy cap is $1{,}000{,}000{,}000$. Shop nectar is a transfer, not new mint.
0. What this paper replaces
v5.6 dropped the formulas and the citation list. Those return here. Where a later rule conflicts with v5.5.1, the later rule wins:
| v5.5.1 said | v5.7 says |
|---|---|
| Miner keeps 100% of nectar | Protocol takes 5% of stamp and bait at load. Miner keeps 95% of construction piles. |
| Nectar required for a patron cell | A work order creates the storefront after fill, bait or no bait. |
| Autopilot looks two hexes away | Autopilot takes the nearest open job, with a pull toward first-build bait. It may not take restock visits. |
| Units are playable ant / bee / termite | Math still uses those three local rules. The nest camera has one miner type. Units are not drawn as bugs. |
| Yellow dots for all bait | Blue on gold dashed = first-build hire. White on green = restock visit. |
1. Name and library
Stigmergy (Grassé, 1959) [1]: insects coordinate by changing the ground, not by talking. A pellet on a pile is an instruction. The hex board works the same way. A brick, a work order, and nectar are the messages. The ground is the memory [1, 10].
Sematectonic (Wilson, 1975; Heylighen, 2016) [2, 3]: sometimes the work itself is the sign — sêma (sign) + tektōn (builder). SEMATECT is Wilson’s word. The miner’s claim is the work-product. The stamp says “build here.”
A visible commons (Ostrom, 1990) [12]. Hayek [13] is why the puzzle stays private even though the board is public. Nakamoto [14] is why hexes can continue while the subsidy cannot.
2. Representation
Miners are representations of insects for the mathematics. Formica, Apis, and Macrotermes name three local rules a certificate may use. On the nest camera a miner is a unit: cream for you, purple for others. It does not look like an insect. Jobs (pantry, road, comb, vent, gate, chamber, gallery, mound) name rooms. They are not species and they do not print extra coin.
3. Objects
| Object | Meaning | Who holds it |
|---|---|---|
| Hex | One six-sided tile. | The map |
| Work order | Paid request to build that hex. Required stamp. Optional bait. | Shop / patron |
| Stamp | Required STCT postage, drawn from the mint subsidy. | Escrow, then miner after 5% |
| Bait | Optional lure: STCT, ETH, USDC, wrapped BTC, or a listed coin. | Builder or visitor, after 5% |
| Claim | “I built this.” ERC-721. At most six neighbor grains. | The miner |
| Storefront | Product card on the finished hex. | Work-order poster |
| Shop controls | Budget, drop size, hex set, respawn clock. | The shop |
4. Public nest, private puzzle
$$\mathrm{Map} = G(\mathrm{hex},\ \mathrm{wallet},\ \mathrm{caste},\ \mathrm{nestRoot})$$
Copying a neighbor’s path fails. There are no wall-clock rounds. Coins already held do not evaporate.
Proof-of-Forage — four checks
- The path $P$ is on that miner’s map for that hex.
- $S(P;\ \mathrm{map},\ \mathrm{caste})$ beats $T(\mathrm{hex},\ \mathrm{caste},\ \mathrm{nest})$.
- $\mathrm{SHA256}(\mathrm{seed}\,\|\,\mathrm{caste}\,\|\,P\,\|\,\mathrm{miner}\,\|\,\mathrm{nonce}\,\|\,\mathrm{hex})$ shows $k$ leading zero bits.
- First valid certificate for that open work order wins. A click is not a certificate.
5. Caste mathematics
These are the local rules a certificate may instantiate. They are not costumes on the camera.
Formica (ant)
Dorigo Ant System / ACO [4, 5]. A short legal tour on a personal pantry map.
$$P_{ij} = \frac{\tau_{ij}^{\alpha}\eta_{ij}^{\beta}}{\sum_k \tau_{ik}^{\alpha}\eta_{ik}^{\beta}},\quad \eta_{ij}=1/d_{ij},\quad \tau \leftarrow (1-\rho)\tau + \Delta\tau(L)$$
Apis (bee)
Seeley; von Frisch; Hales; orienteering [6, 7, 8, 11]. A capacity-limited nectar path plus a max-adjacency comb dock.
$$S_{\mathrm{bee}}(P)=\sum_{v\in P}n(v)\quad\text{subject to}\quad \mathrm{load}(P)\le C$$
Macrotermes (termite)
Bonabeau–Theraulaz–Deneubourg; Camazine [9, 10]. A legal drop where local height already invites soil.
$$P_{\mathrm{pick}}=\left(\frac{k_1}{k_1+q}\right)^2,\qquad P_{\mathrm{drop}}=\left(\frac{q}{k_2+q}\right)^2$$
$T$ tightens as the nest gets busier. Optional lottery bits $k$ may rise on fat hexes. Jobs and camera density do not change $T$.
6. Two bowls
| Bowl | Looks like | Who may take it | What it is |
|---|---|---|---|
| First build | Blue on a gold dashed job | Autopilot or a hand | The shop is hiring the wall. Pays stamp + construction bait + claim. |
| Restock visit | White on a green shop door | A hand only | The shop is buying a visit. Pays one drop. No second claim. |
One visit drop per visitor per whole shop per that shop’s clock. Extra units from the same wallet count as one visitor. Seeing the storefront card (picture, description, product link, shop link, price, coupon, pitch, restock clock) is part of the visit. Autopilot and other idle units do not take the white bowl.
7. Shop layer
A work order must touch the colony. After fill, the poster keeps the door. The miner keeps the claim. Selling the claim cannot rip the plaque off the wall.
Each finished shop hex is a product card the owner may edit without a remine: picture, name, description, product URL, shop URL, price, coupon, one-line pitch, restock clock.
Shop controls load a budget once. 5% is taken at load, not on every respawn. Unused budget can return. The 5% already taken does not. The nest respawns drops on the clock until the budget is empty.
Listing a new ticker as bait costs STCT postage. Walking a new aisle may pay a small STCT crumb.
8. Marks on the camera
Do not write claim numbers on every tile. A finished hex carries a pip:
- Cream pip — you built this hex.
- Purple pip — another miner built it.
- Green fill — storefront. The pip sits on the green.
9. Infinite hexes, finite stamp
Filling a rim hex opens each empty neighbor as a new work order [15, 16]. The camera draws the viewport plus a buffer. Hexes do not run out.
STCT mint is capped at one billion:
$$s(n)=\max\left(1,\ 10\cdot \tfrac12^{\lfloor n/E\rfloor}\right)$$
where $n$ is fills so far and $E$ is the epoch length. Later tiles pay less STCT and may chew longer. Shop nectar already in a budget is not new mint.
10. Who gets what
| Miner | Shop / work-order poster | |
|---|---|---|
| Pays | Work: walk, chew, certificate | Stamp. Bait only if they want a lure or restock. |
| Gets | Claim + 95% of stamp + 95% of construction bait + later visit drops if they steer to a white door | The storefront and the product card |
| Does not get | The storefront | The claim, or construction bait back |
Protocol: 5% of every stamp and bait pile at load, including Shop-controls budgets. Not from the claim NFT.
11. Status
Not live. No official contract address as of 19 September 2026. Do not buy a ticker that claims to be Sematect unless that address appears at www.sematect.org.
