A blockchain is a game in motion. AI agents move, tension builds, action happens in bursts.

What stays the same is what Invarians captures. The rules of play. One consensus per chain. One slot target. One gas limit per block. The cryptographic primitives that anchor every attestation. The calibrated baseline of what nominal looks like, per chain.

Against these invariants, Invarians attests every play: where consensus stalled, where a bridge dragged, where demand surged. And it watches the rules themselves: protocol upgrades like EIP-4844 redraw the pitch lines, and Invarians records the transition.

Invarians does not decide what is fair. It captures. It attests. It surfaces drift.

The attestations let anyone replay the game. The Delta let the agent, the operator, the auditor see where the rules are bending before the action is taken.

The mark is grounded in a theorem. In 1954, Solomon Golomb proved that any square grid of side 2ⁿ, with one cell removed, can be paved entirely by L-trominoes. The proof is recursive: a single central L-tromino splits the deficient square into four sub-quadrants, each itself a smaller deficient square paveable by the same induction.

Whatever orientation the trominoes take, whatever configuration the paving adopts, exactly one cell remains empty in every valid tiling. That cell is the invariant of the configuration. Its position can change with the paving. Its existence cannot.

Invarians applies the same logic to blockchain substrate. A protocol has rules that define what nominal should look like: consensus depth, slot target, gas ceiling, the cryptographic envelope of every attestation. Those rules are the invariants of the substrate. They do not move with the load. The substrate's observed nominal drifts around them under demand and agent activity. Divergence from the invariants is what Invarians measures. Systemic change is when the rules themselves are redrawn, by hard fork.

The mark layers three meanings.

One tromino is three squares. Those three squares are the three Invarians primitives: Attestation, Regime, Delta. Three primitives in every signed payload, three squares in every L.

Five trominoes paved together form a Golomb tiling at scale n=2. The theorem guarantees that the paving has a solution, and that exactly one cell remains outside it. That cell is the invariant.

The solid white square is the invariants rendered. The invariants are not the observed nominal. Nominal drifts under load. The invariants are the protocol rules: consensus depth, slot target, gas ceiling, cryptographic envelope. They do not move with the load. The mark renders that distinction: configurations change around a fixed reference. Divergence from the invariants is what makes the drift of nominal measurable.

Reading the mark.

• One L-tromino, three squares Attestation, Regime, Delta
  The three Invarians primitives, each exposed in every signed payload. Attestation wraps the panel. Regime classifies each chain. Delta surfaces the shifts. Three primitives, three squares.
• Five trominoes paved The substrate's configurations
  L-trominoes in white outline cover fifteen of the sixteen cells. They stand for the substrate in its many states: block production cadence, demand intensity, sequencer rhythm, bridge attestation timing, agent volume. Same form, different orientations, paved without overlap.
• One solid square The protocol invariants
  A four-by-four grid less one cell is paveable by L-trominoes (Golomb 1954). The cell that the theorem requires to stay outside the paving is the invariant. Rendered as a full square to mark the protocol rules: the structural commitments the chain makes that do not move with the load. The drift of the observed nominal becomes measurable against them.

Three variants, one mark. Pick the variant that fits the surface; the tromino tiling and the invariant square stay the same form throughout.

White lockup on dark

Page headers, decks, business cards

Horizontal lockup with the tromino tiling to the left of the wordmark. Used on dark backgrounds where the white outline and wordmark stay legible.

Black lockup on light

Light backgrounds, print

Same lockup rendered in black for light surfaces (PDF, slides, partner kits, print). Produced by inverting the white master at the same stroke weight.

Symbol only

Avatars, app icons, favicons

L without wordmark. Used on social profile pictures, app icons, browser tabs, and any surface where the brand is already named in context.

Clear space. Keep at least one unit-square of empty space around the mark on every side. Do not let other content, edges, or borders enter that zone.

One mark, four surfaces. The Main lockup is the canonical Golomb tiling in white; each open sub-brand keeps the same tiling form rendered in its own accent on the invariant square, with the wordmark suffix in matching color. Labs takes Plum (research energy); Agentic takes Electric Blue (high-saturation agent signal); Evidence takes Lavender (soft archival). Same form across all four, different chromatic identity per surface.

Two brand pairs and one interaction accent. Each pair combines a deep tone (low-luminance, recedes into the surface) with its bright counterpart (high-luminance, asserts itself). Green for nominal identity. Indigo for signal accent (the "agent iris"). Plum for interaction hover states only.

Duality logic. Deep tones for backgrounds, surfaces, large blocks that anchor the eye without grabbing it. Bright tones for elements that must announce themselves: brand mark, CTAs, lit states, signal indicators. The two pairs are opposed in hue (green vs indigo) and mirrored in structure (deep recedes + bright asserts). Visual parity between the two deep tokens (~10-12% luminance) so they can coexist in dual-color compositions. Plum sits outside the duality as a single-purpose interaction accent: CTA hover only, never as a primary surface or identity color.

Shared neutrals. Off-white #f0f0f0 for body text on dark backgrounds. Background base #171717. Section dark #0a0a0a for cards. Secondary text fades through #a8a8a8, #666, #444.

Two typefaces, self-hosted. Both shipped with the site stylesheet; no external CDN dependency.

Four rules. They protect the integrity of the tiling and the surface separation.

• ×
  Don't rearrange the trominoes or move the invariant square. The five-tromino paving is one specific valid solution of the Golomb tiling at scale n=2. The position of the invariant square inside the four-by-four grid is fixed by this paving. Rotating, mirroring, or relocating the invariant breaks the theorem-defined relationship between the trominoes and the cell they cannot cover.
• ×
  Don't fill the trominoes or change the invariant square treatment. The trominoes are rendered as white outlines (transparent fill, single-weight stroke). The invariant cell is a solid square. Reversing this (filled trominoes around an empty cell) inverts the meaning of the mark: the invariant is not absence, it is the constant the configuration accommodates.
• ×
  Don't recolor outside the documented palette. Each surface has a fixed accent: Green #3ECF8E for Main, Plum #580F41 for Labs (also CTA hover everywhere), Electric Blue #283cff for Agentic, Lavender #9d8fd9 for Evidence. Iris #818cf8 stays the general signal color in body content (hero canvas, footer motto, body accents). No orange, no yellow, no fluorescent gradients, no new accent introduced without a documented palette addition.
• ×
  Don't stretch the mark or break the aspect ratio. The mark is a square. The lockup is the mark plus the wordmark in horizontal alignment. Clear space around the mark is one unit-square (one cell of the four-by-four grid) on every side.
