SUBTENSOR RUNTIME · v486

Subtensor v486 corrects how one smart-contract query is charged and makes runtime builds reproducible

Runtime 486 is a small release. It changes how the chain accounts for the execution cost of one query that smart contracts can make into Subtensor, so that the charge better matches the work done. Staking, Emission and other network parameters do not change for TAO holders, Validators or Miners. The rest of the release is release tooling that makes runtime builds reproducible, so anyone can check a published runtime against the code running on chain.

Low impact Validators / Miners

Corrected cost accounting for a smart-contract query

The chain now accounts differently for the execution cost of one query that smart contracts on Subtensor can make, so the charge better reflects the work done. This only affects smart contracts that use this query. Regular staking and transfers do not change.

Source #3289

Other changes

Release tooling now produces reproducible runtime builds and can publish verified releases for runtimes already running on mainnet. Users are not affected.

    Make runtime builds reproducible and publish already-deployed runtimes

    This change makes runtime builds reproducible using a fixed random seed and adds a manual workflow to publish and verify GitHub releases for runtimes that reached mainnet outside the normal release train, which mainly affects developers and the release watcher tooling rather than everyday Validators or Miners.

    release-486

    This change ships runtime 486, which updates how weights are accounted for in a contract chain-extension query and updates the related tests, affecting all network participants once this runtime is deployed.
