Procedural on-chain art protocol · Arbitrum
Art, shaped by every gesture.
Each gesture, made with ETH or CST, extends the cycle’s clock. When it runs out, the cycle is finalized: new Signatures are imprinted for its recipients, and the Cycle Reserve is allocated across its tracks, 7% of it to Ethereum’s core contributors.

Reading the Cycle Finalization Time
The Art
Three-body physics. Art from an on-chain seed.
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.
Cycle 1
Seed5084a8…33ad
- Stage 1
Seed
A 32-byte hash is derived from on-chain data — block information and ArbSys precompiles — then fed into a SHA3-256 RNG.
- Stage 2
Simulation
One hundred thousand candidate configurations run through a 4th-order Yoshida symplectic integrator at one million physics steps each.
- Stage 3
Selection
A Borda rank aggregation (chaos × equilateralness) selects the most visually interesting orbit from the candidate pool.
- Stage 4
Camera
A slow elliptical camera drift gives each Signature a cinematic parallax through the three-body dance.
- Stage 5
Color
Colors are mixed in the OKLab perceptual space with 120° hue separation per body, modulated by drift and a sine wave.
- Stage 6
Spectral render
Sixty-four wavelength bins from 380 to 700 nanometers render the orbit trails with velocity-dependent thickness and depth of field.
- Stage 7
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.

The Cycle
A Performance Cycle, from opening to finalization.
Make a gesture
Take part with ETH or CST. Each gesture is recorded on-chain and enters the cycle’s Stellar Selection.
Extend the clock
Every gesture adds time to the Cycle Finalization Time, so the cycle runs for as long as people keep taking part.
Finalize and allocate
When the clock reaches zero, the cycle can be finalized: new Signatures are imprinted and the Cycle Reserve is allocated across the tracks below.
Allocation Tracks
Every Cycle Reserve, allocated by rule.
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.
ETH from each Cycle Reserve
Signature Allocation
25%To the participant who made the Final Gesture. Includes 1,000 CST and one Cosmic Signature NFT.
Chrono-Warrior Allocation
8%To the participant who held the Endurance Champion position for the longest consecutive interval. Includes 1,000 CST and one Cosmic Signature NFT.
ETH Stellar Selection
4%Split across 3 randomly selected participants. Selection frequency scales with gestures made.
Anchor Distribution
6%Distributed proportionally across all Cosmic Signature NFTs anchored to the protocol for this cycle.
Public Goods Allocation
7%Forwarded to Protocol Guild, the funding mechanism for 170+ Ethereum core contributors.
Compounding Cycle Reserve
~50%Rolls forward into the next Performance Cycle. The protocol compounds rather than extracts.
CST and NFTs, every cycle
Each recipient receives 1,000 CST and one Cosmic Signature NFT.
- 10 recipients
NFT Stellar Selection — Participants
Selected at random from the cycle’s participants.
- 10 recipients
Anchored-NFT Stellar Selection
Selected at random from Random Walk NFT anchor-holders.
- 1 recipient
Endurance Champion Allocation
The participant with the longest unbroken endurance window.
- 1 recipient
Final CST Gesture Allocation
The participant who made the cycle’s last CST gesture.
Public Goods
Every cycle funds Ethereum’s core contributors.
Every Performance Cycle forwards a fixed share 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.

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.
Anchoring
Anchor Cosmic Signature NFTs to the protocol.
Anchor a Cosmic Signature NFT and it receives a proportional share of the 6% Anchor Distribution every cycle, paid out when the anchor is released. You can release it at any time, but each NFT can be anchored only once.
- ETH accrues every cycle and is retrieved at release
- No fixed term and no penalty; releasing is permanent for that NFT
- Random Walk NFTs, from the companion collection, can be anchored too
- Anchored Random Walk NFTs enter the Anchored-NFT Stellar Selection: 1,000 CST and a Cosmic Signature NFT, no ETH
Cosmic Council
Protocol Coordination, on-chain.
CST holders coordinate the protocol on-chain: they delegate weight, submit Coordination Proposals and express Support or Opposition.
Coordination Proposal
Any address with at least 100 CST of delegated weight may submit a proposal. 2-day coordination delay, 2-week coordination period.
Coordination Weight
Each CST expresses one unit of weight once delegated. Expression is a cryptographic signature, not a share or equity instrument.
Coordination Quorum
A proposal passes if Support exceeds Opposition and Support plus Abstain weight reaches 3% of total CST supply. Opposition weight does not count toward the quorum.
Verifiability
Open, verified, reproducible.
Anyone can regenerate a Signature from its seed and check the contracts, source code and audit status the app publishes.
CC0 1.0
Project-owned materials in the Cosmic Signature repositories: contracts, shaders and rendering pipelines. No rights reserved; third-party dependencies, fonts and assets keep their own licenses.
Verification status
The app links public contract addresses, source-code resources, verification context, and audit/report status so anyone can inspect what has been published.
Reproducible art
SHA-256 hashes of generated frames asserted in continuous integration. Same seed → identical output.

Clarifications
Questions worth answering plainly.
What do I actually do as a participant?
You make gestures. Each gesture is an ETH or CST transaction that extends the Cycle Finalization Time, records a Stellar Selection entry, may imprint dynamic Participation CST, and shapes the cycle’s Signature. You may anchor Cosmic Signature NFTs to receive a share of Anchor Distributions. You may submit Coordination Proposals through the Cosmic Council if you hold at least 100 CST.
What is the art, technically?
Each Cosmic Signature NFT is a deterministic render of a three-body Newtonian simulation. The on-chain seed selects a candidate orbit (from 100,000 simulated via a 4th-order Yoshida symplectic integrator), which is then spectrally rendered across 64 wavelength bins with OKLab color mixing. The pipeline is fully open-source under CC0; anyone can reproduce a Signature from its seed.
Where do the ETH allocations come from?
From the Cycle Reserve, which grows as participants make gestures. When a cycle finalizes, about half rolls forward into the next cycle’s Compounding Reserve; the remainder is distributed across allocation tracks (Signature Allocation, Chrono-Warrior, Anchor Distribution, Stellar Selection, Public Goods) per on-chain parameters.
What exactly is Public Goods?
7% of each cycle’s ETH reserve is forwarded to a public-goods address, currently Protocol Guild. Protocol Guild is the collective funding mechanism for 170+ Ethereum core contributors. This is a forwarding of ETH to a public-goods address; it is not a charitable contribution in the U.S. tax sense, and Cosmic Signature makes no representation about its tax treatment.
Is this a lottery, casino, or gambling product?
No. Cosmic Signature is a procedural on-chain art protocol. Participants make gestures during a Performance Cycle; the protocol distributes allocations across its allocation tracks when the cycle finalizes. There is no house, no dealer, no bet. Allocations recognize endurance, timing, and participation. The one random allocation track, Stellar Selection, is a protocol-level procedural distribution.
Is any of this an investment?
No. CST tokens express participation and coordination weight within the protocol, not equity, profit share, dividend, or investment contract. No team wallet receives ETH from participant gestures. Cosmic Signature makes no representation about token price or future behavior and does not solicit participation as an investment.
Why does the Participation CST amount change?
The Participation CST imprint uses a square-root formula based on how long it has been since the previous gesture. Longer quiet periods create larger CST imprints, but the square root makes the increase sublinear. Very rapid gestures can imprint 0 CST. The app previews the current amount before you submit.
How do ETH and CST gestures affect the CST Calibration Window?
The CST Calibration Window is stored on-chain and changes after every gesture. A CST gesture lengthens it by about 0.4%, making CST Gesture Cost descend more slowly. An ETH gesture shortens it by about 0.398%, making CST Gesture Cost descend faster.
Can I fork this?
Yes. Project-owned contracts, shaders, renderers, marketing pages, and documentation are dedicated under CC0 1.0 — no rights reserved. Third-party dependencies, fonts, and assets remain under their own licenses; see THIRD_PARTY_NOTICES.md.
