If blockchains are immutable… what happens when Earth isn’t? 🔭

What if your next node wasn’t on AWS…
but on a satellite orbiting Earth?
This isn’t sci-fi. It’s called The Astral Ledger — a concept where blockchains are backed up in space.

The Astral Ledger: What If We Log Blockchain to the Stars?

🛰️ Why store a blockchain beyond Earth?

  • 🌍 Political censorship? Space doesn’t care.

  • ☢️ Global disaster? The ledger survives.

  • 📡 One truth, broadcast from the sky.

Imagine an orbital node that syncs Ethereum, Bitcoin, or IPFS, and beams verified blocks globally, forever — untouchable, uncensorable, and permanent.

🌌 Real Experiments

  • Blockstream Satellite: Bitcoin data broadcast from space since 2017

  • IPFS + CubeSats: Academic proposals for low-orbit decentralized storage

  • Aleph.im exploring interplanetary file networks

🧠 The Implications:

  • A Ledger of Last Resort — if Earth burns, the data lives

  • Decentralization goes interstellar

  • Proof-of-history becomes… cosmic truth

This isn’t just a blockchain. It’s a monument to human intent.

Proof of what we valued — stored among the stars.
