What this referendum means

What was proposed?

This referendum upgraded the live Vara runtime from specification version 1501 to 1620.

Why it mattered

A runtime upgrade changes the executable rules of the chain and can alter pallets, APIs, transaction behavior and governance mechanics.

An Aye vote meant…

An Aye vote supported installing runtime specification 1620.

A Nay vote meant…

A Nay vote opposed this runtime upgrade.

What happened or is happening

The archive compared state_getRuntimeVersion at blocks 16423699 and 16423700. specName remained “vara,” while specVersion changed from 1501 to 1620.

The whitelisted dispatch returned success, and the runtime version changed from 1501 to 1620 at the execution block.

Dispatch the whitelisted runtime-upgrade preimage that changed Vara's runtime spec version from 1501 to 1620.

Node operators still needed compatible software and operational procedures, but those actions were not encoded in the referendum call.

Observable on-chain result

Dispatch returned success.

At execution block 16423700, state_getRuntimeVersion changed from specVersion 1501 to 1620.

Promised outcomes

Install Vara runtime specification 1620.

Verified outcomes

Historical chain state confirms the 1501 → 1620 runtime transition at execution.

Follow-up: verified-complete

Still unknown

The archived referendum metadata does not include release notes describing every behavioral change bundled into this runtime.
