The novel computational data structure known as a blockchain provides an open, public, distributed ledger that has many promising applications. However, any new cryptographic application should take into account anticipated technological development expected to occur within the lifespan of any potentially deployed systems, many of which will be in operation for decades. This document examines vulnerabilities of blockchain technology manifested by the development of quantum computers and gives general recommendations on how to make blockchain more resistant to such technological advances.
