Quantum breaks the signatures every major chain uses
Shor's algorithm recovers a private key from its public key. Bitcoin, Ethereum and most other chains sign with curves it breaks, and their ledgers keep every exposed key forever.
BTC already sit behind a public key that is visible on-chain.
less quantum hardware than earlier estimates to break a 256-bit curve key.
bigger signatures after migration: 64 B Schnorr to 3,309 B ML-DSA-65.

Quantum is the first shift.
Not the last.
Shor's algorithm
Recovers private keys from public keys. ECDSA, Schnorr, Ed25519 and BLS fall.
Proven math, hardware maturingGrover's algorithm
Square-root speed-up on hashing. Thinner security margins and an edge in proof-of-work mining.
Proven math, smaller impactNew cryptanalysis
Young post-quantum schemes can break. SIKE and Rainbow fell to ordinary computers in 2022, so systems must be able to swap algorithms.
Has happenedImplementation attacks
Timing, power and fault attacks target new post-quantum code before it is hardened.
Active researchNew compute substrates
Photonic and neuromorphic hardware change the cost and speed of proof-of-work, randomness and consensus.
Our research thesisWhat we build
Migration Lab
We move chains, bridges, custody and signing systems to post-quantum cryptography, then prove it with NIST vectors and attack tests.
Next-era R&D
The BlockShor testnet and SDK: chain components built to run on quantum, photonic and neuromorphic hardware.
Shoreline-1
A hardware wallet that signs with post-quantum keys for Bitcoin, Ethereum and our own testnet.
Migration
Lab
For teams running their own chains, bridges, custody, exchanges or signing services. We map your quantum exposure and move you without breaking what already works.
- 01
Inventory
Find every key, signature and hash in the system.
- 02
Exposure map
What is at risk now, and what breaks on Q-day.
- 03
Design
Pick schemes, hybrid or full post-quantum, and an upgrade path.
- 04
Build & test
Implement, then prove it with NIST vectors and attack tests.
- 05
Roll out
Hardware signing, key rotation and monitoring.
BlockShor
testnet
A chain built for next-era hardware. Node roles are swappable: each runs on real hardware where it exists today, and on emulation where it doesn't yet.
Sign with ML-DSA
Every transaction is signed post-quantum, natively on Shoreline-1.
Quantum randomness
A cloud quantum computer picks the next block producers.
Photonic proof of work
Emulated photonic hardware produces blocks.
Neuromorphic consensus
Simulated spiking-network nodes vote on blocks.
Final block
Needs two-thirds of validators' post-quantum signatures.
SDK
Developer tools for plugging existing chains into new compute backends. Follows the testnet.
