Post-quantum peer to peer digital value
Qbit is quantum-secure from inception and built to be the most durable digital store of value: no premine, 100% community distribution, and Bitcoin-backed security.
At a Glance
Key specs.
- Signature algorithm
- SLH-DSA-SHA2-128s-bounded30
- The active post-quantum signing profile used to authorize Qbit spends.
- Signature family
- SLH-DSA / SPHINCS+
- A conservative hash-based signature family designed to resist quantum attacks on classical signatures.
- Signature size
- 3,680 bytes
- The serialized size of each active spend signature under Qbit's bounded SLH-DSA profile.
- Spend model
- P2MR + OP_CHECKSIGPQC
- Outputs commit to hidden spend paths, then reveal and verify only the selected path when spent.
- Block envelope
- 2,000,000 bytes / 2,000,000 weight
- The block size and weight limit that bounds validation, storage, and relay cost.
- Aggregate cadence
- 60 seconds
- The target average time between blocks across Qbit's native and AuxPoW mining lanes.
- Mining
- SHA-256 + AuxPoW
- Qbit supports permissionless SHA-256 mining and merge-mined Bitcoin-linked security.
- Difficulty
- ASERT, 2-hour halflife
- The adjustment algorithm that keeps block production stable as hashrate changes.
- Supply cap
- 210,000,000 QBT
- The fixed maximum supply enforced by Qbit's consensus issuance schedule.
