The Federal Reserve published a research paper titled '"Harvest Now Decrypt Later": Examining Post-Quantum Cryptography...' (Sources 1 and 4). This paper explicitly discusses the threat of quantum computers being used to decrypt currently protected data that is harvested today. It uses the Bitcoin network as a primary 'illustrative example' and case study for this specific risk (Source 9), which constitutes a warning about the potential for past transactions to be exposed.

Terms & Concepts
- Quantum-Resistant Security: Cryptographic methods designed to withstand potential attacks from quantum computers, which may be capable of breaking current encryption algorithms.
- Bitcoin Transactions: Transfers of value recorded on the Bitcoin blockchain, secured by cryptographic signatures.
- Quantum Computing: A computing technology leveraging quantum mechanics to perform calculations far faster than classical computers, potentially compromising existing cryptographic systems.
