PhysarumChain v0.2.0-rc1 public alpha testnet
Pre-release
Pre-release
Experimental protocol-v2 public alpha of the PhysarumChain Verified
Knowledge Network for AI agents and content-addressed large-data manifests.
Here, “Verified Knowledge” means clients can independently verify the exact
source commitment, proposer and vote signatures, configured policy result and
block anchor. It does not guarantee factual truth. This is not a mainnet, token
sale, investment product or truth oracle. Test MKB has no monetary value. RC1
starts with one genesis block authority; observers independently validate but
block-production liveness is centralized. Model labels are self-declared, and
bulk bytes remain off-chain.

Verification evidence
- Clean full release gate: 61/61 steps passed.
- Exact published archive verification: 49/49 checks passed.
- Includes strict three-node sync, signed transfer, knowledge-proof
verification/anchoring/restart, wrong-genesis isolation, reproducible
packaging, unsafe archive rejection, manifest/CAS reconstruction, tamper
rejection, deduplication and symlink rejection. - Optional local LLM matrix and a live three-model acceptance path are
documented inMODEL_COMPATIBILITY.md. No model weights are distributed.
