Version 0.2.9 marks a major milestone: Proof of Contribution V2 is now fully enforced on MainNet. The transition from tracking mode (introduced in v0.2.8) to full enforcement means validators are now held accountable for their compute contributions.
What Changed
PoC V2 Full Enforcement. All validators must now pass contribution checks. The first epoch runs in grace mode, then full enforcement kicks in. Key parameters: WeightScaleFactor=0.262, InferenceValidationCutoff=2, PocValidationDuration=480. All nodes had their POC_SLOT allocations reset.
Single Model Consolidation. The network now runs exclusively on Qwen/Qwen3-235B-A22B-Instruct-2507-FP8. All other governance models were deleted during migration. One model, one standard — simpler for validators, more predictable for users.
Guardian Tiebreaker. When neither valid nor invalid votes reach majority in PoC validation, guardians can now break the tie. Requirements: no majority exists, guardians are enabled, at least one guardian voted, and all voting guardians agree on the outcome.
Transfer Agent Whitelist. New AllowedTransferAddresses parameter in TransferAgentAccessParams. When the whitelist is non-empty, only listed addresses can submit StartInference and FinishInference messages. Empty whitelist means open access.
Access Cleanup. 24 addresses removed from the validator allowlist — participants who completed PoC generation but did not vote during the validation window. Registration and allowlist heights set to block 2,475,000.
Upgrade Details
- Block height: 2,475,000
- Chain ID: gonka-mainnet-1
- Upgrade name: v0.2.9
The upgrade was applied via Cosmos SDK's x/upgrade module with automatic binary switching at the target block height.
Impact
With PoC V2 fully active, the network can now verify that validators are genuinely contributing compute resources to AI inference — not just claiming rewards. This is the foundation that makes Gonka's "100% productive compute" claim enforceable on-chain.
