Why 'Bunker Mode' Means Moving Coins to Addresses That Have Never Signed a Transaction
Bitcoin and Ethereum addresses are derived from public keys by hashing them, so as long as a wallet has never spent from an address, its public key stays hidden behind that hash. The moment a transaction is signed, the public key is published on-chain and becomes a fixed target for anyone who can solve the elliptic curve discrete logarithm problem underlying ECDSA. Justin Drake's 'bunker mode' proposal is built entirely around this exposure gap: his specific recommendation was 'to set in motion a controlled mass migration of assets to fresh addresses' [1]that have never signed a transaction, keeping their public keys off-chain and unreachable until the owner chooses to spend. The scale of what's already exposed is the real motivator - research firm Project Eleven's 'Bitcoin Risq List' put the amount of BTC sitting in addresses with visible public keys at over 8.17 million coins as of mid-September 2026, with an earlier estimate putting it at 6.04 million BTC, roughly 30% of circulating supply [2]. That's the pool of funds bunker mode is trying to shrink before any theoretical break happens, not after.
