Pyde: A post-quantum, MEV-resistant Layer 1 with sub-second finality
Version 0.2 · 2026 · Pyde Network · Apache-2.0
What it is, in one paragraph
Pyde is a Layer 1 blockchain built greenfield to ship four properties as defaults from genesis. Each is a protocol-level decision, not an opt-in layer. Each is shipped together because shipping any one of them after a chain is live is a multi-year coordinated migration.
- 01
Post-quantum cryptography
FALCON-512 signatures, Kyber-768 threshold encryption, Poseidon2 + Blake3 hybrid hashing. No pre-quantum primitive on any consensus or account path.
- 02
MEV resistance
Threshold-encrypted mempool + commit-before-reveal ordering. Sandwich attacks, front-running, and proposer extraction are not policed or auctioned; they are structurally impossible.
- 03
Sub-second finality
Mysticeti consensus, ~500ms median commit finality, an 85-of-128 FALCON quorum certificate.
- 04
Commodity-hardware decentralization
Full nodes and validators awaiting committee selection run on 8 cores / 16 GB RAM. Validators on the active committee at production throughput require a 500 Mbps – 1 Gbps NIC; every committee seat carries one vote regardless of stake.
The full document covers the 2026 architectural pivot from in-house HotStuff to Mysticeti DAG, the cryptography stack in detail, the hybrid parallel execution scheduler, the commit-before-reveal MEV defense, the slashing catalog, the parachain framework, and the performance discipline the protocol commits to at v1 mainnet — throughput numbers published only after a multi-region harness measures them, never lab extrapolations.
No public launch dates. Mainnet ships when the audits pass and the harness numbers hold.
