Bitcoin produces a block every ten minutes, and the whole world sees the same new hash at once. Detonate it: the hash fixes constants like gravity, the speed of light and the number of dimensions, and a physics engine plays that universe forward from its first second to heat death — to see whether it can grow stars, chemistry, even observers.
The simulation yields a universe like ours, not ours. If you like it, mint it as an NFT; if it is dead, burn BANG to rescue it. It mints into the very same BNBBANG contract and pays out the very same BANG — this site only swaps the fuse.
Every frame below is a screenshot of the engine rendering live, untouched. They come from BNB-block universes on the sister site bnbbang.com — Bitcoin blocks run through the same engine and the same renderer. Each carries its source block; detonate the same block and this is what you get, or recompute it yourself with the open-source engine.
The first two are nearly free. The third is the only scarce thing here.
Pick a Bitcoin mainnet block: its hash deterministically unfolds into a full set of physical constants, and the engine plays out that universe on the spot. Same block, same universe — recomputable, not selectable.Derivation is open source — recompute it yourself: github.com/q3579338/bnbbang-engine
Open the simulator →Keep it once it has 6 confirmations: it shares a hard cap of 1,707,000 with bnbbang.com. The first 1,000,000 are free and come with 50 BANG (10 per address across both sites); 0.01 BNB after that. One hash mints once — first come, first served.
Visit the market →Most universes grow nothing. Burn BANG to nudge its constants and rescue a dead universe into one that can bear observers. Every token burned is destroyed for good, with no cut taken (current skim 0, contract cap 20%).
Read the token economy →Bitcoin keeps the slowest and most public beat in the world: one block every ten minutes on average, and nobody can know the next hash in advance. The moment a block lands, anyone can look; after 6 confirmations (about an hour) it opens for minting, and whoever mints first keeps it.
A miner finds a hash under the difficulty target, roughly 19 leading zeros. Those 32 bytes existed nowhere before — now they are a set of physical laws.
A block with fewer than 6 confirmations can still be reorganised, and a changed hash is a different universe. So you can look and fly through it in 3D, but the mint button waits for its birth certificate to be stamped — the page counts down.
The sixth confirmation lands and the block opens on both sites at once. One hash mints only once — first come, first served, verifiable on-chain. The genesis block and the four halving blocks open on 2026-09-12 at 12:00 UTC, first come first served.
Physical grade (S/A/B/C/D) depends on the hash alone; named blocks are a second layer on the card, each computed from the height or backed by a public source. Badges do not touch the physics — a halving block still has a 93% chance of blowing up into rubble.
| Badge | Rule | Count | Notes |
|---|---|---|---|
| Genesis | #0 | 1 | The first block, 2009-01-03. Opens 12 Sep 12:00 UTC, first come first served |
| Halving | #210000 · #420000 · #630000 · #840000 | 4 | The first block after each 210,000-block subsidy halving. Opens 12 Sep 12:00 UTC |
| Difficulty-period first block | h mod 2016 = 0 | ≈480 | Difficulty adjusts every 2016 blocks; the first block of each period |
| Named blocks | #1 · #170 · #57043 · #74638 · #481824 · #709632 | 6 | First mined block · first transaction (Satoshi → Hal Finney) · the pizza · the value-overflow incident · SegWit activation · Taproot activation |
BTCBANG issues no new token, opens no new pool and deploys no new contract. It mints into the same NFT contract as bnbbang.com and pays out the same BANG — even the 10 free mints per address share one counter.
Scarcity was never in the singularity; it is in the magazine. Bitcoin has 960 thousand blocks and BNB 120 million, both inexhaustible; the two sites together have only 1,707,000 slots. A second fuse adds no slots — it only adds a crowd that will pay for Bitcoin hashes, racing for the same magazine.
The two markets are one: BTC universes and BNB universes trade side by side, labelled "₿ #height" and "BNB #height". Anyone can take the height to the matching chain, check the hash, and know where it came from.
| BNBBANG | BTCBANG | |
|---|---|---|
| Singularity | BNB block hash · one every 3 s | Bitcoin block hash · one every 10 min |
| NFT contract | MirrorUniverse 0x1661…aa78 the same | |
| Token | BangToken 0xa530…42d the same | |
| Supply | 1,707,000 universes, one shared counter | |
| Free period | First 1,000,000 × 50 BANG, 10 per address across both sites | |
| Paid period | 0.01 BNB → NFT + 600 BANG | |
| Mint requirement | Self-proven on-chain within 256 blocks | ≥ 6 confirmations, checked server-side against Bitcoin nodes |
| Market · naming · rescue · referrals | One system, valid across both sites | |
Blocks are unlimited — Bitcoin has 960 thousand, BSC over a hundred million, and both keep growing. So "drawing a good universe" cannot carry value.
Only one thing can: rescuing a universe means really burning BANG, and BANG is finite.Every NFT is stamped with the total BANG burned on it during interventions (naming burns are counted separately), readable on-chain, impossible to fake.
Names work the same way: naming a universe burns BANG, look-alike names are folded together for the uniqueness check, and a taken name stays taken.
| BANG token | Count | Notes |
|---|---|---|
| Supply | 1 billion | Zero premine: the constructor mints nothing |
| Mint rewards | 600 million | Only the NFT contract can issue it; after the cap, anyone can trigger the permanent burn of the remaining ~126 million |
| Referral rewards | 200 million | Tier-1 10%, tier-2 5%, paid after manual review; sybil accounts are not paid |
| Team | 100 million | 24-month linear unlock, no early-withdrawal backdoor |
| Exchange listing fees | 100 million | Every grant carries its reason on-chain, fully auditable |
The same eight contracts as bnbbang.com; addresses and live status are read straight from the chain. Universe parameters are signed server-side before minting, and the signature is bound to the chain and contract, so it cannot be forged. For Bitcoin blocks the on-chain verified bit is always false (BSC cannot see Bitcoin); verify by taking the height to any Bitcoin node and comparing the hash.
Invite friends to detonate universes: 10% of a friend's mint reward goes to you, and 5% from a friend's friend — paid from the 200M referral pool after manual review, with an on-chain trail.
The referral pool is 200M BANG. Sybil accounts (self-invites, bulk alts, wash activity) are not paid after manual review.
