ten_cubed — The social network that stops growing

ten_cubedHOW IT WORKSBENEFITSTRADE-OFFSTHE QUERY AN ARTIFICIALLY RESTRICTED SOCIAL GRAPH

ten_cubed caps your network at 10 close connections across 3 degrees of reach, a hard ceiling that mirrors how human trust actually works. No feeds tuned for virality. No followers. No influencers.

10 × 10 × 10/MAX 1,110 CONNECTIONS/USER-CONTROLLED DEPTH/DUNBAR-ALIGNED

YOU 1

THE ROOT NODE

DEGREE 01 10

CLOSE FRIENDS & FAMILY

DEGREE 02 100

A SMALL VILLAGE

DEGREE 03 1,000

EACH ○ = 10 NODES A SMALL CITY

10 + 100 + 1,000 = 1,110 TOTAL REACHABLE NODES

10 MAX DIRECT CONNECTIONS

Adding an 11th means removing one. The 1st degree stays coveted.

1,110 HARD NETWORK CEILING

Three degrees, ever. No app or service can exceed it.

0 INFLUENCERS, EVER

No follower counts to accumulate. Nothing to enshittify.

SEC. 02 — HOW IT WORKS

Three rules. One bounded graph.

RULE / 01

Hard cap of ten

You can never hold more than ten direct connections.

RULE / 02

Three degrees of reach

Ten friends, one hundred friends-of-friends, one thousand at the third degree. A family, a village, a small city. Dunbar-scaled by design.

RULE / 03

You set the depth

Users choose how deep their network reaches. Privacy-first? Stop at 10. Open? All 1,110. Never more.

SEC. 03 — WHY BOUND THE GRAPH

What scarcity gets you.

Virality meets friction

Content propagates to your 3rd degree, then stops. Coordinated manipulation simply doesn't scale.

Meaningful connections

With only ten slots, the 1st degree is coveted and deeply trusted. Apps can build on that trust in ways hyper-scaled networks never could.

No influencer economy

Nobody can accumulate followers, so nobody can monetize an audience in questionable ways. The enshittification cycle never starts.

SEC. 04 — KNOWN TRADE-OFFS READ BEFORE BUILDING

⚠ 01

Not built for broadcast

One-to-many platforms don't map to ten_cubed. Your audience caps at 1,110 by design. If you need unbounded reach, this isn't your graph.

⚠ 02

The graph is volatile

Drop a 1st-degree connection and their entire branch vanishes with them. Apps must decide: hide orphaned content, label it, or cancel pending transactions.

SEC. 05 — IMPLEMENTATION

The entire graph is one recursive query.

No graph database. No infrastructure. A single recursive CTE walks the network outward from any user, respecting each connection's own max_degree along the way. Drop it into Postgres and you have a bounded social graph.

- PLAIN POSTGRESQL — WORKS IN ANY APP

- RESPECTS EVERY USER'S MAX_DEGREE SETTING

- DEPTH-BOUNDED: NEVER WALKS PAST DEGREE 3

friend_of_friend.sql WITH RECURSIVE / PG 14+

``` -- Set once per session: SET ten_cubed.user_id = '42'; SET ten_cubed.max_depth = '3';

WITH RECURSIVE friend_of_friend AS ( SELECT connections.target_id, users.max_degree, 1 AS depth FROM connections JOIN users ON connections.target_id = users.id WHERE connections.user_id = current_setting('ten_cubed.user_id')::bigint

UNION ALL

SELECT connections.target_id, users.max_degree, depth + 1 FROM connections JOIN users ON connections.target_id = users.id JOIN friend_of_friend ON connections.user_id = friend_of_friend.target_id WHERE depth < current_setting('ten_cubed.max_depth')::int AND depth < users.max_degree ) SELECT DISTINCT ON (users.id) users.*, friend_of_friend.depth AS degree FROM users JOIN friend_of_friend ON users.id = friend_of_friend.target_id WHERE users.id != current_setting('ten_cubed.user_id')::bigint ORDER BY users.id, friend_of_friend.depth; ```
