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.

🛰️ 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 2017IPFS + CubeSats: Academic proposals for low-orbit decentralized storageAleph.im exploring interplanetary file networks
🧠 The Implications:
A Ledger of Last Resort — if Earth burns, the data livesDecentralization goes interstellarProof-of-history becomes… cosmic truth
This isn’t just a blockchain. It’s a monument to human intent.
