Overview
Week 19 of 2026 (May 4 to May 8) pushed 12 issues to close across the main gonka repo. The dominant theme is inference validation — four PRs landed to bound, restructure, and fix the validation pipeline that verifies AI compute results on-chain. DevShard infrastructure continued maturing with snapshots and structural changes building on the Postgres backend that shipped last week. A bridge handler refactor and several smaller fixes round out the week.
Inference Validation: Bounded and Restructured
The inference validation flow received significant attention this week, touching four separate issues:
- Issue #952 — Inference validation optimization proposal closed after the proposed changes landed. This long-standing proposal outlined how to reduce the computational overhead of on-chain inference checks without weakening security guarantees.
- PR #1144 — Inference validation flow restructured the validation pipeline to separate concern boundaries. The chain node now delegates validation orchestration to the API node more cleanly, reducing duplicated checks.
- PR #1125 — Bound inference validation work introduced hard upper bounds on the amount of work a single validation round can perform. This prevents pathological cases where a burst of inference requests could stall the validator.
- PR #1147 — Fix devshard inference invalidation fixed a bug where invalidated inference results were not properly cleaned from devshard storage, potentially causing stale data to persist across epochs.
Together, these changes make inference validation more predictable under load and reduce the blast radius of misbehaving inference sessions.
DevShard Infrastructure Continues to Mature
Last week saw the major Postgres backend landing (#1145, covered in a standalone post). This week, follow-up work consolidated the new architecture:
- PR #1149 — Snapshot for devshards added snapshot support, allowing host operators to capture devshard state at a specific epoch for backup or debugging. This is particularly useful for the hybrid Postgres+SQLite mode introduced in the previous PR.
- PR #1126 — DevShard structure cleaned up the internal data model, aligning struct definitions and access patterns with the new storage backends.
- PR #1098 — DevShards Postgres support closed as the underlying work was absorbed into the broader Postgres migration.
Bridge Handler Refactor
PR #1151 — Bridge setup in handler moved bridge initialization logic into the upgrade handler. Previously, bridge setup ran during node startup as a separate init step. Moving it into the handler means bridge configuration is now versioned alongside the upgrade itself, reducing the risk of config drift between binary upgrades.
Smaller Fixes and Improvements
- PR #1140 — Default node manager gRPC config set sensible defaults for the node manager's gRPC configuration. Operators who run standard deployments no longer need to manually specify connection parameters.
- PR #1146 — Fix wasm permission corrected a permission issue in the WASM module that blocked certain contract operations.
- Issue #866 — Onboarding clarity enhancement closed after documentation and setup flow improvements aimed at reducing friction for new host operators.
- Issue #912 — Add PoC report added a structured reporting mechanism for Proof of Compute rounds, giving operators better visibility into their validation performance.

What to Watch
The inference validation work suggests the team is preparing for higher inference throughput. With the validation pipeline now bounded and the devshard storage layer on Postgres, the groundwork is in place for scaling the number of concurrent AI sessions per host. The bridge handler refactor also hints at continued preparation for the Ethereum bridge going live.
