Akash Mainnet 16 Upgrade

This proposal upgrades the Akash Network to version v1.2.0 at block height 25789395 estimated to occur on Wednesday, March 4th at 14:00 UTC.

Note: Block times have high variance. Please monitor the chain for more precise timing estimates.

Upgrade Features

By voting YES on this proposal, you approve the following changes:

• Public rollout of the CometBFT Tachyon advisory fix CSA-2026-001: Tachyon (previously distributed as binary-only to validators).
• Migrate deployment and market module stores from manual KVStore key encoding to cosmossdk.io/collections.IndexedMap, replacing hand-rolled prefix keys with type-safe, indexed collections
• Add secondary indexes (State, Owner, Provider) enabling efficient filtered queries without full-store iteration
• Record lease closed reason on MsgCloseBid, allowing providers to specify why a lease was closed (e.g. Unstable). The reason is persisted on the lease and returned in query responses
