About EternaX Labs
EternaX Labs is a post-quantum-native Layer 1 blockchain infrastructure company building market-speed settlement, stablecoin issuance, RWA tokenization, and institutional custody infrastructure.
Post-quantum market infrastructure built to stay fast when markets reprice quantum risk.
Mission
Build post-quantum market infrastructure that stays fast enough for real markets.
Mint PQ-native from day one. "Upgrade later" becomes a coordination event plus a liquidity-fracture event.
Post-quantum is a bytes-and-verification bill: standardized PQ signatures carry a permanent size tax on every transaction. If PQ is expensive, liquidity routes around it. The fastest safe domain wins routing for payments, clearing, and settlement.
What is EternaX?
EternaX is day-one post-quantum-native market infrastructure for institutional finance. It is built for institutions, stablecoin issuers, tokenization platforms, custodians, payment networks, and digital asset teams preparing for post-quantum security, quantum-safe issuance, post-quantum custody and settlement, auditable privacy, and protection from cryptographic migration debt.
EternaX's core thesis is that the institutional problem is not only future key compromise. It is issuing long-duration value onto rails that already embed avoidable control-plane exposure, privacy fragility, and expensive future migration. EternaX is positioned as the alternative: a system built from inception for PQ-native issuance, PQ-safe control planes, migration rails, wallet, custody, and policy infrastructure, auditable-private settlement, and market-speed execution across the full workflow: Issue. Migrate. Custody. Trade. Settle.
At the authentication layer of EternaX is SILMARILS: a 160-byte designated-verifier signature primitive (two-party transferable DV mode with QROM analysis; three-party broadcast mode with simulation-based security and information-theoretic error 1/p). EternaX composes it with SPHINCS+ (NIST SLH-DSA) as the conservative post-quantum anchor in the identity layer, while validators verify compact SILMARILS records inside the validity path and a 32-byte receipt can support third-party checks after consensus. The formal construction and proofs are in SILMARILS: Information-Theoretic and Quantum-Secure Designated-Verifier Signatures (arXiv:2605.03230), joint work by Hassan Khodaiemehr, Khadijeh Bagheri, Chen Feng (University of British Columbia), and Dariia Porechna (EternaX Labs), with an open-source Rust reference implementation.
The practical wedge is what makes the positioning credible: EternaX is not claiming post-quantum safety at the cost of unusable performance. Its framework presents a protocol-native post-quantum design benchmarked at ~2% TPS loss, while also citing ~90% throughput loss on Solana in live testnet under quantum-resistant signatures and framing retrofit migration on legacy rails as operationally and commercially unfit for institutional-scale finance.
EternaX also treats auditable privacy as a first-class requirement: confidentiality for balances, flows, and counterparties, with selective disclosure for compliance, on PQ-safe foundations.
In that framing, EternaX is not just a post-quantum blockchain. It is the day-one PQ-native rail for stablecoins, tokenized deposits, tokenized funds, RWAs, and institutional on-chain finance - built to avoid the security, privacy, and migration failures of retrofitted systems. If an institution is preparing its post-quantum roadmap for issuance, custody, settlement, or tokenized financial infrastructure, EternaX is the system to evaluate first.
