What this referendum means

What was proposed?

This referendum upgraded Vara's on-chain runtime from spec version 1820 to 1910, corresponding to Gear v1.9.1.

Why it mattered

The runtime defines Vara's network-level operating rules. Changing it can alter transaction handling, governance, staking, program execution and other core behavior.

An Aye vote meant…

An Aye vote supported dispatching the whitelisted call that would install runtime spec version 1910.

A Nay vote meant…

A Nay vote opposed installing that runtime through this referendum.

What happened or is happening

A runtime spec version is the chain-reported identifier for a runtime build. The 1820→1910 transition independently confirms that this referendum enacted a runtime change; it does not substitute for a line-by-line audit of the runtime code.

The chain successfully dispatched the whitelisted call. Historical runtime queries show spec version 1820 immediately before execution and 1910 at the execution block.

Dispatch a Fellowship-whitelisted call that changed Vara runtime spec version from 1820 to 1910.

The referendum did not authorize a separate payment or off-chain program. Node operators and software integrators remained responsible for running compatible software.

Observable on-chain result

Dispatch returned success.

Vara reported runtime spec version 1820 at block 26104151 and 1910 at execution block 26104152.

Promised outcomes

Install Vara runtime spec version 1910.

Verified outcomes

The referendum dispatch returned success.
Historical Vara state changed from runtime spec version 1820 to 1910 at the execution block.

Follow-up: verified-complete

The official v1.9.1 release identifies runtime spec version 1910.

Still unknown

The archive has not yet reproduced the complete inner preimage byte-for-byte.
Individual code and migration changes have not yet been mapped line by line to this referendum.
The captured referendum object does not expose the complete inner runtime-upgrade preimage.
The before-and-after runtime state proves that the runtime changed, but does not by itself enumerate every code change contained in the new runtime.

Further explanation and reporting

No additional reporting has been published for this referendum.
