What Is "Harvest Now, Decrypt Later"?
HNDL is a strategy where attackers collect encrypted data today with the intent to decrypt it using future quantum computers. For crypto, this is especially dangerous because blockchain data is permanently public — every transaction ever made is stored forever on the chain.
Why Blockchain Is Uniquely Vulnerable
- Permanent public ledger: Every transaction is stored forever and publicly accessible
- Public keys are exposed: When you send a transaction, your public key is revealed
- No retroactive fixes: You can't retroactively quantum-proof past transactions
- High-value targets: Whale wallets with millions in crypto are obvious targets
Who's Doing the Harvesting?
Intelligence agencies, state-sponsored hackers, and sophisticated criminal organizations are all known to collect encrypted communications and blockchain data. The cost of storage is negligible compared to the potential payoff when quantum decryption becomes available.
The Only Defense: Quantum-Safe Transactions from Day One
BMIC's quantum-safe wallet protects against HNDL by using NIST-approved post-quantum signatures from the moment of transaction. Unlike retrofitting quantum safety onto existing wallets, BMIC builds it in from the ground up.
