AmericanFortress, an organization growing 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 hundreds of thousands of already-exposed legacy wallets — stays a key problem.
At 0G, we’re constructing the foundational infrastructure for an AI-native economic system and that infrastructure have to be safe towards threats that don’t but exist at scale however will. AmericanFortress has solved 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 characteristic, 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.
Nevertheless, a sufficiently superior quantum laptop working Shor’s algorithm may change that, enabling the derivation of personal keys from public keys and probably 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 quite than a theoretical one.
Google has just lately printed analysis highlighting vulnerabilities in present cryptographic methods, whereas initiatives equivalent to Circle’s Arc are working to implement post-quantum protections.
The plan to sort out the menace
The patent submitting goals to handle this danger. Its quantum-resistant public derivation scheme is designed to be appropriate with quantum-proof signatures.
The corporate plans to license this know-how to different blockchains as a retrofit answer, positioning it as comparatively simple to implement.
Below this mannequin, Ship-to-Identify™ transactions can be quantum-safe end-to-end, and any blockchain adopting the system may obtain quantum-resistant safety for each customers and AI brokers.
We invented Ship-to-Identify™ to make crypto as straightforward and secure 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 following era of digital finance truly wants.
AmericanFortress mentioned it has constructed a unified privateness infrastructure for blockchain transactions, combining human-readable names, stealth deal with privateness, zero-knowledge stability confidentiality, built-in compliance, and post-quantum safety right into a single system designed to work throughout supported chains.
The corporate mentioned the $8 million seed spherical will probably be used to speed up manufacturing deployment of its privateness infrastructure and help the deliberate $AF token era occasion, focused for Q2 2026.
