DUBLIN, Oct. 14, 2022 /PRNewswire/ — The report “The Quantum Threat to Blockchain: Emerging Business Opportunities” has been added to ResearchAndMarkets.com’s offering.
This new research report identifies not only the challenges, but also
the opportunities in terms of new products and services that arise from
the threat that quantum computers pose to the “blockchain” mechanism.
According to a recent study by the consulting firm Deloitte,
approximately one-fourth of the blockchain-based cybercurrency Bitcoin in circulation in 2022 is vulnerable to quantum attack.
The analyst foresees major commercial opportunities arising to
protect blockchain against future quantum computer intrusions and agrees
with the White House National Security Memorandum NSM-10, released on May 04, 2022,
which indicates the urgency of addressing imminent quantum computing
threats and the risks they present to the economy and to national
security in the latest report “The Quantum Threat to Blockchain: Emerging Business Opportunities”.
Although the main focus of this report is on the quantum threat to
the integrity of cybercurrencies, the applicability of blockchain (and
therefore the threat of quantum) is much broader than the newer types of
money. Blockchain technology has been proposed for a wide range of
transactions, including insurance, real estate, voting, supply chain
tracking, gambling, etc.
A quantum computer-compromised blockchain would allow eavesdropping,
unauthorized client authentication, signed malware, cloak-in encrypted
session, a man-in-the-middle attack (MITM), forged documents, and
emails. These attacks can lead to mission-critical operations
disruption, reputation, and trust damage, as well as loss of
intellectual property, financial assets, and regulated data. Note that
this report covers both technical and policy issues relating to the
quantum vulnerability of blockchain.
As things stand now, blockchains are secured with relatively
garden-variety encryption schemes. However, quantum computers will have
the computational power to break these schemes as they grow in power.
Predictions of when quantum computers will attain such power vary from
five years to never, but, the threat hangs over the cryptocurrency industry as a whole and is a dampener to its prospects.
Quantum computers directly threaten classical public-key/private key
cryptography blockchain technologies because they can break the
computational security assumptions of elliptic curve cryptography. They
also significantly weaken the security of critical private key or hash
function algorithms, which protect the blockchain’s secrets.
Also, some of the early expenditures on quantum-safe technology in
the cybercurrency market will undoubtedly go to protecting data from
attacks later, when quantum computing resources become mature. This
issue becomes more important as we grow closer to the day when powerful
quantum computers become a reality. But preemptive action on the quantum
threat means that the business opportunities in this space are emerging
right now.
As this report makes clear, the publisher sees major commercial
opportunities to protect blockchain and the technologies dependent on
blockchain against future quantum computer intrusions. One area that
this report focuses on especially is post-quantum encryption (PQC), in
which relatively traditional encryption schemes are devised that are
simply much harder to break than currently used encryption schemes. With
NIST announcing a new set of PQC standards in July 2022,
the publisher believes that PQC firms will be receiving major
investments in the near term as a result of the growing concerns about
bad actors with access to quantum computing resources.
The publisher believes there is also a need for relatively low-cost
information-theoretically secure (ITS) solutions that instantly
strengthen standardized cryptography systems used in blockchains. Thus,
this report also discusses quantum-enabled blockchain architectures
based on Quantum Random Number Generators (QRNG) and Quantum Key
Distribution (QKD).
Key Highlights:
- With NIST announcing a new set of PQC standards in July 2022,
PQC firms will soon be receiving major investments in the near term ,
much of which will apply to blockchain. However, not all NIST-based PQC
solutions will be feasible for blockchain use. Given the nature and
intricacy of PQC, it will take years of planning for a successful
migration to PQC-backed Blockchain protection. - The earliest of expenditures on quantum safe technology in the block
chain market will go to protecting data from attacks later, when
quantum computing resources become mature. This issue becomes more
important as we grow closer to the day when powerful quantum computers
become a reality. But data theft today requires preemptive action. The
quantum threat to the blockchain means that business opportunities in
this space are emerging right now. - There is a need for low-cost information-theoretically secure (ITS)
solutions that instantly strengthen standardized cryptography systems
used in blockchains. Already much discussed in this context are
quantum-enabled blockchain architectures based on Quantum Random Number
Generators (QRNG) and Quantum Key Distribution (QKD). Another important
concept is quantum-enabled blockchain, which refers to an entire
blockchain or some aspects of the blockchain functionality being run in
quantum computing environments. - Mining is another aspect of blockchains vulnerable to quantum
attacks. Mining is the consensus process that certifies new transactions
and keeps blockchain activities protected. One risk with mining is that
miners using quantum computers could launch a 51% attack. A 51% attack
is when a single entity controls more than half of the computational
power of the blockchain. A quantum attack on mining would undermine the
network’s hashing power.
