The first Shiba in space — now on its own blockchain. 42, 69, and a whole lot of luck.
Asteroid Shiba is the first Shiba Inu to travel to space, launched aboard a SpaceX rocket alongside the Polaris astronauts — traveling the farthest distance from Earth ever recorded in human history.
The story begins with Liv Perrotto, a passionate space enthusiast who can recount every rocket mission by heart. After surviving cancer in 2021, Liv was inspired by Hayley Arceneaux — a fellow cancer survivor turned astronaut. Liv was invited by the Polaris Program to design the zero-gravity indicator: a Shiba Inu plush named Asteroid Shiba, inspired by Elon Musk's own Shiba, Floki.
During SpaceX's live broadcast of the first-ever commercial spacewalk, Asteroid Shiba was featured prominently. The design and its story were shared with millions of viewers worldwide. Asteroid Shiba plushies are available for purchase at the official SpaceX and Polaris Program stores, with all proceeds donated to St. Jude Children's Research Hospital.
Liv's message to the world: "If Asteroid Shiba can go to space, so can they. Everyone should chase their own dreams."
ASTEROID carries that spirit forward — a blockchain born from the cosmos, where every block reward is lucky, because space is full of surprises.
| Parameter | Value |
|---|---|
| Algorithm | Scrypt |
| Block Time | 60 seconds |
| Total Supply | 42,069,000,000 ASTRO (42.069 billion, hard cap) |
| Reward Type | Lucky v2 (random per block + jackpot tiers via Mersenne Twister) |
| Difficulty Adjustment | Every 20 blocks (pre-Digishield) → every block after block 50,000 (Digishield) |
| Merge Mining | Supported (AuxPoW) |
| Genesis | 2026 |
Block rewards are not fixed — they're randomized within a range using the previous block's hash as a seed, ensuring deterministic but unpredictable rewards. Every block is a lucky draw, and special blocks hit jackpots.
| Era | Block Range | Base Reward (ASTRO) | Lucky Range (ASTRO) | Blocks | Duration | Avg Emission | % |
|---|---|---|---|---|---|---|---|
| 1 | 0 — 144,999 | 69,420 | 34,710 — 104,130 | 145K | ~101 days | 10.07B | 28.7% |
| 2 | 145,000 — 564,999 | 42,069 | 21,034 — 63,103 | 420K | ~292 days | 17.67B | 50.3% |
| 3 | 565,000 — 1,254,999 | 6,942 | 3,471 — 10,413 | 690K | ~479 days | 4.79B | 13.6% |
| 4 | 1,255,000 — 2,944,999 | 1,337 | 668 — 2,005 | 1,690K | ~1,174 days | 2.26B | 6.4% |
| 5 | 2,945,000 — 5,654,999 | 420 | 210 — 630 | 2,710K | ~1,882 days | 1.14B | 3.2% |
| 6 | 5,655,000 — 8,364,999 | 69 | 34 — 103 | 2,710K | ~1,882 days | 187M | 0.5% |
| 7 | 8,365,000 — 11,109,999 | 4 | 2 — 6 | 2,745K | ~1,906 days | 11M | 0.03% |
| 8 | 11,110,000+ | 0 | — | ∞ | perpetual | 0 | — |
Total average emission: ~36.1B ASTRO across ~11.1M blocks (~21 years).
Special blocks receive multiplied rewards based on their block height:
| Tier | Trigger | Multiplier | Approx. Frequency |
|---|---|---|---|
| Mega Jackpot | Every 69,420 blocks | ×69 | ~every 48 days |
| Mini Jackpot | Every 4,206 blocks | ×42 | ~every 3 days |
| Lucky Strike | Every 420 blocks | ×21 | ~every 7 hours |
Example: At Era 1 (base 69,420), a Mega Jackpot block yields 2.4M — 7.2M ASTRO instead of the normal 34,710 — 104,130.
Every number tells a story: 42, 69, 420, 1,337, 4,206, 69,420 — meme math all the way down.
- Block 0 — 49,999: Retarget every 20 blocks (~20 minutes), standard Bitcoin-style
- Block 50,000+: Digishield activated — difficulty adjusts every single block, providing rapid response to hashrate changes and protection against attacks
