Satoshi's private keys aren't sacred. We know the companies who can break them.

Context

A Shift In History

Quantum computers (QCs) are no longer science fiction. Google, Microsoft, Amazon, IBM, and other tech giants already have live QCs. Yet, today's digital infrastructure is totally unprepared.

Post-quantum retrofitting faces hard limits.

Mixing old and new cryptography leads to partial protection, inconsistent tooling, and dangerous trust assumptions.

Upgrade paths remain vague or nonexistent.

Ethereum, Bitcoin, Solana—none have credible, coordinated PQ migration paths.

The Immutability Trap.

Great for trust, but if chains aren't quantum-secured from block 0 it critically compromises them towards inevitable attacks (e.g. the exposure of Satoshi's private keys).

Solution

Quantum Security by Design

A chain engineered to secure the next era of digital systems from block zero: purpose-built for quantum security, designed for real-world scale.

01
Made for Eternity
Eterna ensures a rock-solid foundation for all your favourite on-chain use cases to flourish: DeFi, stablecoins, payments, real-world assets (RWA), digital identity (DID) — you name it. Like Ethereum, but quantum-secure, scalable, and private.
02
Purpose-built
Eterna exists to outlast any future cryptographic challenges: it replaces vulnerable elliptic curve cryptography (from BTC, ETH, and most chains) with the most secure post-quantum algorithms like CRYSTALS-Dilithium and Kyber, both selected by NIST as standards against quantum attacks.
03
Beyond Quantum
Besides quantum safety, Eterna also delivers a privacy-respecting user experience, and best-in-class performance: up to 30k TPS — on par with Solana and 1,000x faster than Ethereum.

Features

Privacy & Scalability

Eterna carefully combines breakthroughs in scalability (30k TPS), privacy (ZK and FHE), and post-quantum cryptography — giving builders a future-proof foundation with everything they need to scale their protocols from thousands to millions, and eventually billions.

Fully Homomorphic EncryptionFHE enables computation directly on encrypted data. This has advantages similar to ZK-Proofs, but for compute. Transactions are processed entirely over encrypted inputs, outputs, and logic — no plain text ever touches the network.

FHE-Native Virtual MachineFirst ever VM based on Fully Homorphic Encryption (FHEVM), enabling smart contract execution entirely in the encrypted domain, preserving confidentiality throughout program logic.

Compliant PrivacyDual-Key disclosure architecture enables selective regulatory access without compromising end-user confidentiality through threshold-controlled decryption.

MIR-BFT Parallel ConsensusMultiple leaders propose blocks simultaneously — removing the single-proposer bottleneck of traditional BFT protocols, boosting throughput and reducing latency.

Sharded Execution with Transaction BucketingTransactions are deterministically routed into buckets and distributed across leaders, allowing concurrent block building without conflict or duplication.

Optimized FHE BootstrappingRefreshes encrypted data mid-computation to maintain correctness and avoid noise overflow — essential for deep, multi-step logic at scale.
