- Hedera will retire its Alpha State Proof (ASP) feature by February 10, 2026.
- ASP provided cryptographic proof that specific transactions occurred on the Hedera network.
- Two brownout periods are scheduled before the final shutdown to identify dependencies on ASP.
- Developers must remove or update any applications relying on ASP before the deprecation date.
- Support and guidance will be available through Hedera’s official Discord and community channels.
Hedera is planning to discontinue its Alpha State Proof (ASP) service on the Hedera network. ASP allowed developers to retrieve mathematical proof verifying that given transactions took place on the network and their results, independent of any individual node. This feature was accessed through the Hedera Mirror Node, such as via the REST API endpoint GET /transactions/{transactionId}/stateproof.
The deprecation timeline includes two test shutdowns or “brownouts.” The first brownout is set for December 2, 2025, lasting one hour starting at 10:00 AM CST. A longer brownout will follow on January 6, 2026, for 12 hours from the same start time. These interruptions are designed to highlight remaining dependencies on the ASP feature across applications.
The Alpha State Proof service will be permanently shut down on February 10, 2026. After this date, no state proof data will be generated or available through Hedera Mirror Nodes. Any requests to the state proof endpoints will fail. Hedera has advised developers to use the brownout periods to test their systems and to remove or refactor any ASP-related functionality before the final shutdown.
The deprecation impacts any projects or software built with ASP functionality, including those using mirror nodes or software development kits (SDKs) that produce state proofs. Developers should prepare accordingly to avoid disruptions in their applications. For assistance during this transition, users can reach out through Hedera’s Discord or other official community channels.
ASP was introduced as an experimental feature to provide cryptographic verification of transaction data. This approach ensured trustworthiness independent of any single node’s honesty. With the network’s maturation and evolving technology, Hedera is retiring the alpha-stage feature as part of ongoing improvements.
