Venture Eleven has raised $6 million to guard bitcoin
BTC$104,742.13
from the existential menace of quantum computing, as fears mount that the community’s core cryptography might at some point be rendered out of date.
The spherical was co-led by Variant Fund and Quantonation, with participation from Citadel Island Ventures alongside founding traders Nebular and Formation, based on a launch.
“As quantum computing capabilities advance, the menace to methods like Bitcoin is now not theoretical, it is imminent,” Alex Pruden, CEO of Venture Eleven, stated in a launch.
“This funding permits us to remain forward of that curve, constructing the instruments, requirements, and ecosystem required to make sure digital belongings stay safe in a post-quantum world,” Pruden stated.
Earlier this yr, Venture Eleven launched the Q-Day Prize, providing 1 BTC to the primary group that may break Bitcoin’s elliptic curve cryptography (ECC) utilizing a quantum laptop.
“We outline Q-Day because the second when quantum computer systems change into able to breaking the elliptic-curve cryptography that secures non-public keys utilized by Bitcoin,” stated Conor Deegan, co-founder and VP of Engineering at Venture Eleven in a launch.
Venture Eleven additionally introduced it’s launching Yellowpages a post-quantum cryptographic registry the place customers can generate hybrid key pairs, create proofs linking them to their present BTC addresses, and timestamp these proofs on a verifiable ledger.
Yellowpages works by having customers generate a brand new key pair utilizing post-quantum cryptographic algorithms, equivalent to lattice-based methods, which are immune to the sorts of assaults a future quantum laptop might launch.
They then create a cryptographic proof linking this quantum-safe key to their present BTC handle. That proof is timestamped and saved in Yellowpages, a public registry hosted off-chain.
It doesn’t transfer funds or alter something on the Bitcoin blockchain, however creates a verifiable paper path of pockets possession that would function a fallback if elliptic curve cryptography is ever damaged.
“Making ready forward of Q-Day means guaranteeing that digital belongings stay safe and verifiable in a post-quantum world. With Yellowpages, we’re giving customers free, audited, and open-source instruments to proactively set up quantum-resilient possession immediately,” Deegan continued.
Securing BTC towards quantum via consensus
The method contrasts with options like QRAMP, a Bitcoin Enchancment Proposal that mandates a hard-fork migration to quantum-safe addresses.
Whereas efficient in principle, QRAMP and comparable proposals face a excessive barrier to adoption as a result of they’d require consensus, a tall order in a governance surroundings recognized for warning.
Ethereum’s multi-year journey to Proof-of-Stake and Bitcoin’s current OP_RETURN debate are reminders of simply how gradual protocol change could be, and a few analysts have warned that the gradual governance course of is a menace itself.
This route would bypass the necessity for consensus, whereas additionally facilitating the mass adoption of quantum defenses.
As Rick Maeda of Presto Analysis just lately warned in an interview with CoinDesk, quantum defenses have to be constructed linearly, not reactively, as a result of by the point the menace is actual, it’s already too late.
Venture Eleven’s newest strikes recommend some within the crypto business are taking this menace significantly whereas acknowledging the weak spot of present strategies.
