AmericanFortress, an organization creating a common privateness layer for blockchain, introduced it has closed an $8 million seed funding spherical co-led by SAVA Digital Asset Fund, Moon Pursuit Capital, and 0G Labs.
Alongside the funding, the corporate has filed a patent for quantum-resistant cryptographic transaction signing.
The announcement comes amid rising issues across the safety of blockchain cryptography, as timelines for potential quantum threats look like accelerating.
Grayscale Analysis has referred to as for sooner efforts to make public blockchains quantum-resistant, highlighting that decentralized governance — significantly choices round tens of millions of already-exposed legacy wallets — stays a key problem.
At 0G, we’re constructing the foundational infrastructure for an AI-native financial system and that infrastructure should be safe towards threats that don’t but exist at scale however will. AmericanFortress has solved learn how to make blockchain transactions genuinely quantum-resistant with out sacrificing usability, compliance, or privateness. Co-leading their seed spherical displays our conviction that post-quantum safety isn’t a future function, however a gift necessity. 0G is proud to be the primary chain to carry this know-how to manufacturing.
The quantum menace
All main blockchains — together with Bitcoin, Ethereum, and the networks constructed on high of them — depend on elliptic curve cryptography (ECC) to safe wallets and authorize transactions.
ECC is taken into account safe as a result of the underlying mathematical issues are infeasible for classical computer systems to unravel.
Nonetheless, a sufficiently superior quantum laptop working Shor’s algorithm might change that, enabling the derivation of personal keys from public keys and doubtlessly permitting attackers to entry wallets whose public keys have appeared on-chain — which incorporates most lively wallets.
The quantum menace to blockchain is more and more considered as a near-term danger slightly than a theoretical one.
Google has just lately printed analysis highlighting vulnerabilities in current cryptographic programs, whereas initiatives equivalent to Circle’s Arc are working to implement post-quantum protections.
The plan to deal with the menace
The patent submitting goals to deal with this danger. Its quantum-resistant public derivation scheme is designed to be suitable with quantum-proof signatures.
The corporate plans to license this know-how to different blockchains as a retrofit resolution, positioning it as comparatively simple to implement.
Beneath this mannequin, Ship-to-Title™ transactions could be quantum-safe end-to-end, and any blockchain adopting the system might obtain quantum-resistant safety for each customers and AI brokers.
We invented Ship-to-Title™ to make crypto as straightforward and protected as sending a Venmo. Now, with this patent submitting, we’re including a layer of safety that protects each transaction towards the quantum menace horizon. We’re proud to be the primary naming and privateness infrastructure to file for post-quantum transaction signing. Along with 0G, we’re constructing the infrastructure that the subsequent era of digital finance really wants.
AmericanFortress stated it has constructed a unified privateness infrastructure for blockchain transactions, combining human-readable names, stealth tackle privateness, zero-knowledge steadiness confidentiality, built-in compliance, and post-quantum safety right into a single system designed to work throughout supported chains.
The corporate stated the $8 million seed spherical can be used to speed up manufacturing deployment of its privateness infrastructure and assist the deliberate $AF token era occasion, focused for Q2 2026.
