- Is the quantum menace overhyped?
Challenge Eleven has raised $20 million to construct defenses towards the existential menace quantum computing poses to cryptocurrency. The spherical values the startup at $120 million.
The corporate is backed by heavyweights from its June 2025 seed spherical, together with crypto-native VC Variant Fund and quantum tech fund Quantonation.
Challenge Eleven is getting ready for “Q-Day.” That is the theoretical occasion when quantum computer systems grow to be highly effective sufficient to interrupt the encryption that secures the web and monetary methods.
Bitcoin, Ethereum, and most main blockchains depend on Elliptic Curve Cryptography (ECC) for producing private and non-private keys. A sufficiently highly effective quantum laptop working Shor’s Algorithm may theoretically reverse this course of.

This is able to enable an attacker to empty any pockets the place the general public key has been uncovered.
In response to the startup’s estimates, roughly $718 billion price of Bitcoin has been uncovered since it’s sitting in susceptible wallets.
The answer
Challenge Eleven is particularly engaged on “post-quantum” infrastructure for present blockchains. Their flagship product, which known as “Yellowpages,” capabilities as a cryptographic registry that enables customers to signal a message proving they personal a susceptible Bitcoin deal with and hyperlink it to a quantum-secure identification.
This creates a “fallback” document of possession that might be used to recuperate funds if the primary community had been compromised.
Is the quantum menace overhyped?
As of in the present day, the consensus amongst cryptographers, authorities businesses, and market analysts is that the speedy menace of quantum computer systems breaking Bitcoin is overhyped,
Most authoritative voices agree {that a} “Q-Day” occasion is just not occurring this yr (or anytime quickly).
That stated, Ethereum’s Buterin not too long ago warned that elliptic curve cryptography may find yourself being compromised by quantum computing earlier than 2028.
