In a revised paper published on December 5, Blockstream researchers Mikhail Kudinov and Jonas Nick propose that hash-based signature technology could be a key solution to protecting the $1.80 trillion Bitcoin blockchain from quantum computer threats.
The researchers believe that hash-based signatures are a compelling post-quantum solution because their security relies entirely on a mechanism similar to the hash function assumptions already in Bitcoin's design. The scheme has undergone extensive cryptographic analysis during the National Institute of Standards and Technology's (NIST) post-quantum standardization process, strengthening the credibility of its robustness.
Older Pay-To-Public-Key Bitcoin wallets created before 2012 (including Satoshi Nakamoto's $98 billion worth of holdings) are estimated to contain about $600 billion of Bitcoin, and these wallets will be the first to face the threat of quantum computers.
