Every Gesture Shapes the Signature.
A procedural on-chain art protocol on Arbitrum. Make a gesture during a Performance Cycle, and every gesture shapes the cycle’s final Signature. When the cycle closes, the protocol distributes its reserves across more than ten allocation tracks — including the infrastructure Ethereum itself depends on.
A Performance Cycle, from open to finalization.
A cycle is a window in time. It opens with a Calibration Window, fills with gestures, and finalizes when the Cycle Finalization Time expires. No houses. No dealers. Just the protocol.
- 01
Cycle Opening
A new Performance Cycle begins. The Calibration Window opens: Gesture Cost descends from the Calibration Ceiling toward the Calibration Floor over roughly two days.
- 02
Gestures
Participants make gestures with ETH or CST. Every gesture imprints Participation CST, extends the Cycle Finalization Time, and shapes the cycle’s evolving Signature.
- 03
Finalization
When the Cycle Finalization Time expires, the participant who made the Final Gesture may finalize the cycle. After the exclusivity window, the Open-Finalization Window opens to anyone.
- 04
Allocations
The protocol distributes the Cycle Reserve across more than ten allocation tracks. About half of the ETH reserve rolls into the next cycle’s Compounding Reserve.
The Three Body Problem, rendered on-chain.
Every Cosmic Signature NFT visualizes three celestial bodies orbiting under Newtonian gravity. Three bodies produce fundamentally chaotic trajectories. No AI. No training data. Just deterministic physics. Same seed → identical output, pixel for pixel.
- Stage 01
Seed
A 32-byte hash is derived from on-chain data — block information and ArbSys precompiles — then fed into a SHA3-256 RNG.
- Stage 02
Simulation
One hundred thousand candidate configurations run through a 4th-order Yoshida symplectic integrator at one million physics steps each.
- Stage 03
Selection
A Borda rank aggregation (chaos × equilateralness) selects the most visually interesting orbit from the candidate pool.
- Stage 04
Camera
A slow elliptical camera drift gives each Signature a cinematic parallax through the three-body dance.
- Stage 05
Color
Colors are mixed in the OKLab perceptual space with 120° hue separation per body, modulated by drift and a sine wave.
- Stage 06
Spectral Render
Sixteen wavelength bins from 380 to 700 nanometers render the orbit trails with velocity-dependent thickness and depth of field.
- Stage 07
Signature
AgX tonemapping, bloom, OpenSimplex nebula layers, and color grading finish the frame. The result: a 16-bit PNG plus a 30-second H.265 video.

More than ten ways the protocol distributes the Cycle Reserve.
When a cycle finalizes, the protocol distributes its ETH and CST reserves across allocation tracks that recognize endurance, timing, dedication, and participation. About half of the ETH reserve compounds into the next cycle.
Allocation
25%
Signature Allocation
To the participant who made the Final Gesture. Includes 1,000 CST and one Cosmic Signature NFT.
Allocation
~50%
Compounding Cycle Reserve
Rolls forward into the next Performance Cycle. The protocol compounds rather than extracts.
Allocation
8%
Chrono-Warrior Allocation
To the participant who held the Endurance Champion position for the longest consecutive interval. Includes 1,000 CST and one Cosmic Signature NFT.
Allocation
7%
Public Goods Allocation
Forwarded to Protocol Guild, the funding mechanism for 170+ Ethereum core contributors.
Allocation
6%
Anchor Distribution
Distributed proportionally across all Cosmic Signature NFTs anchored to the protocol for this cycle.
Allocation
4%
ETH Stellar Selection
Split across three randomly selected participants. Selection frequency scales with gestures made.
Allocation
10 NFTs
NFT Stellar Selection — Participants
Ten randomly selected participants each receive 1,000 CST and one Cosmic Signature NFT.
Allocation
10 NFTs
Anchored-NFT Stellar Selection
Ten randomly selected Random Walk NFT anchor-holders each receive 1,000 CST and one Cosmic Signature NFT.
Allocation
1,000 CST
Endurance Champion Allocation
1,000 Recognition CST and one Cosmic Signature NFT to the participant with the longest unbroken endurance window.
Allocation
1,000 CST
Final CST Gesture Allocation
1,000 Recognition CST and one Cosmic Signature NFT to the participant who made the last CST gesture of the cycle.
Anchor Cosmic Signature NFTs to the protocol.
Anchored Cosmic Signature NFTs receive a proportional share of the 6% Anchor Distribution each cycle. Release the anchor whenever you like. Anchored Random Walk NFTs receive entries into the Anchored-NFT Stellar Selection, where selected anchor-holders receive 1,000 CST and a Cosmic Signature NFT.
- Per-cycle ETH distribution for anchor-holders
- Release anchors at any time
- Random Walk anchors enter the Stellar Selection
- No lockup, no penalties, no fixed term
7% of every cycle funds Ethereum’s core contributors.
Every Performance Cycle forwards 7% of its ETH reserve to Protocol Guild — the collective funding mechanism for 170+ Ethereum core contributors. The more the protocol is used, the more flows to the infrastructure Ethereum itself depends on.
Cycle Allocation
7%
of every Performance Cycle is forwarded to Protocol Guild.
Disclaimer
This is a forwarding of ETH to a public-goods address (currently Protocol Guild). It is not a charitable contribution in the U.S. tax sense, and Cosmic Signature makes no representation about its tax treatment.
Protocol Coordination, on-chain.
The Cosmic Council coordinates the protocol on-chain. CST holders submit Coordination Proposals and express Support or Opposition. The Coordination Quorum is met at 3% of CST supply. Proposal threshold: 100 CST.
Coordination Proposal
Any CST holder with at least 100 CST may submit a proposal. Two-day coordination delay, two-week coordination period.
Coordination Weight
Each CST expresses one unit of weight. Expression is a cryptographic signature, not a share or equity instrument.
Coordination Quorum
A proposal passes if support exceeds opposition and 3% of total CST supply has expressed a position.
Open, verified, reproducible.
Anyone can verify a Signature by regenerating it from its seed. All contracts have been audited and are formally verified with Certora. The whole repository is CC0 — no rights reserved, fork and remix encouraged.
CC0 1.0
Every contract, every shader, every rendering pipeline. No rights reserved. Public domain.
Audited & Formally Verified
All contracts have been audited prior to deployment. Certora formal verification on core contract invariants and Slither static analysis run in CI.
Reproducible Art
SHA-256 hashes of generated frames asserted in continuous integration. Same seed → identical output.
