Every Arc block hash is a universe
That star field is the engine computing, right now. It flashes once for every new Arc block.
Detonate it. The hash gives you 23 constants: how strong gravity is, how fast light travels, how many dimensions space has. The engine takes them and runs the universe from its first second to heat death, to see whether it grows stars, planets, life.
Engine, live
Every frame is a screenshot of the engine rendering live, untouched. There is a universe with spatial dimension D = 18 in here — D is how many dimensions space has; ours has 3 — a 2.5-dimensional black plane, a D = 1 spacetime diagram and a D = 2 disc world. Universes with D above 4 make up 55% of all blocks: no stable orbits exist there, matter either flies apart or falls into the core. Draw D = 14 and the engine really runs the N-body in 14 dimensions, then projects onto the three axes you pick; change the axes and the same universe shows another face.The engine is open source — recompute it yourself.

That is all there will ever be. One universe stands for ten million years, so the full set comes to 13.787 billion — the age of this universe.

Three actions
Detonation is free and unlimited, minting is optional, and what you mint is yours to transfer.
1Detonate
Pick an Arc block. The hash expands on the spot into a full set of physical constants and the engine runs that universe’s whole life. Arc closes a block every 0.5 seconds and nobody has detonated any of them yet. recomputable, not selectable.The engine is open source — recompute it yourself
Detonate →2Mint
See the result first, then decide whether to mint. 1,387 pieces, no further issuance ever. 887 are free (387 guaranteed plus 500 first-come), one per address, costing only about 0.003 USDC in gas. The price of the remaining 500 will be announced separately, with at most 3 per address.

What you mint is a standard NFT. List it on the built-in market, or on OpenSea.
Go to the market →Find your universe
Paste an Arc block height, or a 0x block hash. The block from your birthday, the block your first transaction landed in, anything. The same hash is the same universe, whoever detonates it.
One hash, one universe
Arc closes a block every 0.5 seconds, about 170,000 a day. Detonation is free and unlimited.
Minting is the part you get one shot at. One block hash grows exactly one universe and it belongs to whoever mints it first. 1,387 pieces. No further issuance, ever. Once someone mints the one you picked, there is no second copy.
ARCBANG issues no token and runs no presale or airdrop, and there is no unlock schedule. What you get is an NFT.
| ARCBANG | Amount | Notes |
|---|---|---|
| Hard cap | 1,387 | The universe is 13.787 Gyr old and one NFT is ten million years; hard-coded in the contract |
| Free | 887 | 387 guaranteed + 500 first-come, one per address, gas only (about 0.003 USDC) |
| After that | Price to be announced | At most 3 per address; the price is bounded above and below by contract constants |
| Secondary royalty | 5% | Markets like OpenSea read it straight off the NFT |
Four rules
Four rules, all of them checkable.
Free to detonate, mint what you want
Detonation costs nothing and has no limit. You decide whether to mint after seeing the result.
One block hash, one universe, forever
A hash can be minted once. Once someone else takes it, there is no second copy of that universe.
No token
No presale, no airdrop, no unlock schedule, and no promises of returns.
Fully verifiable
The hash is the seed and the engine is open source. The same hash computes the same universe on your machine.
On-chain status
Addresses and live state of both contracts, read straight from the chain.
The contracts are not deployed to Arc mainnet yet. Once they are, the two cards above will show their on-chain status automatically.
