02 / THE FOUNDATION
Different
at the core.
Post-quantum design starts with the cryptography. The engineering continues with every trade-off it creates.
Inside the protocolTwo signatures. One requirement.
Bloch requires ML-DSA-65 and Falcon-1024 together. Larger keys and signatures are part of that choice.
Privacy, built from hashes.
Coherence explores SHAKE-256 commitments and STARK proofs. The proving scaffold remains unaudited.
Designed in the open.
Specifications, implementation, and stated limitations belong in the same conversation. Inspect the work and its assumptions.

Explore supplyEvery stage has its limits.
The published record describes an unaudited network launched under one operator. New validator admission requires verified release and network configuration.

SIGNATURES
POST-QUANTUM SIGNATURES
An optional hash-based suite
The hybrid ML-DSA-65 + Falcon-1024 construction stays the default for everything. A new optional SLH-DSA + Falcon-1024 suite is intended for cold storage, treasury and long-term holdings: a hash-based floor if lattice cryptography is ever weakened.
CONSENSUS
FINALITY
Stronger finality under network partitions
Finality is counted over a frozen validator set, and a validator’s votes are counted only for the chain that validator is on.
VERIFIABILITY
EXCHANGES, WALLETS, LIGHT CLIENTS
Verifiable finality certificates
A certificate that proves a checkpoint is final, so exchanges, wallets and light clients can check finality without trusting an RPC provider.
VALIDATORS
SIGNER PROTECTION
Validator signer protection
The validator signer blocks duplicate instances of the same key and restored old backups from signing.
VALIDATORS
KEY-EVOLVING SIGNATURES
Forward-secure validator keys
Key-evolving signatures (KES) for validators: signing keys evolve over time, so validator keys are forward-secure.
