BunkerCoin

BunkerCoin aims to move blockchain consensus onto shortwave radio, building a Layer 1 that does not depend on internet infrastructure. A private testnet already moves blocks and votes as PACTOR frames over real HF frequencies, using an adaptation of Solana's Alpenglow consensus tuned for a link that carries only a few kilobits per second: a block is notarized, then finalized, and a missed slot is handled with a skip certificate.

Shortwave reflects off the ionosphere, so a single link can span a continent, while ordinary users reach the chain through internet gateways that serve the wallet and explorer; without internet, nodes can be reached directly over radio. The project holds a roughly 70,000 square metre underground complex near Halberstadt, Germany, with ownership recorded in the local land register and trade register, which it designates as a site for radio nodes. BUNKER is a meme token on Solana with a supply of 1 billion, distinct from the valueless test coins handed out by the testnet faucet, and node, wallet and explorer code is developed in public repositories.
