Mainnet Crescendo Release - v1.0.0

This release introduces the Crescendo Hardfork, transitioning the Kaspa network from 1 BPS to 10 BPS. This marks a significant increase in transaction throughput and network capacity, as well as improved network responsiveness due to shorter block intervals, enhancing the overall user experience. Crescendo is scheduled to activate on mainnet at DAA Score 110,165,000, projected to occur on May 5, 2025, at approximately 15:00 UTC.

Starting 24 hours before activation, nodes will connect only to peers using the new P2P protocol version 7. Ensure your node is updated to maintain network connectivity.

Key highlights for Kaspa node maintainers

• 10 BPS Activation: Mainnet will transition from 1 BPS to 10 BPS.
• Retention Period Configuration: Operators now have greater control over data management with a new retention-period-days configuration. Due to the higher block rate, the pruning period has shortened from approximately 50 hours to 30 hours. If operators wish to retain the same amount of historical data as before, they should specify the desired retention period using the new configuration and ensure sufficient storage capacity is available.
• Protocol Version Update: Nodes will switch to P2P protocol version 7. Ensure your node is upgraded to maintain connectivity.

Retention period configuration

The new retention-period-days parameter provides flexibility for node operators by determining how many days of historical data to retain.

Configuration	Type	Usage
retention-period-days	f64	The number of days to keep data for. Must be at least 2. If not set, the node will default to keeping only data for the pruning period.

Example: Keep 2.5 days (=60 hours) of data using the following command:

./kaspad --utxoindex --retention-period-days=2.5

Crescendo specification

For full details of the changes activated in this hardfork, refer to KIP-14.

Node upgrade guide

Ensure your node is updated to stay compatible with the Crescendo Hardfork. For detailed instructions on upgrading and configuring your node, refer to the Crescendo Guide.

Notes

• This version includes an optimization that significantly reduces base RAM usage especially in 10BPS networks
• It also includes a new configuration for retention period. See below

New Configuration

Configuration	Type	Usage

Sample Usage - Keep 30 days worth of data:

./kaspad --utxoindex --retention-period-days=30

Testnet 10 Crescendo Release - v0.17.0

This pre-release of Kaspa 0.17.0 introduces support for the upcoming Crescendo Hardfork on Testnet 10 (TN10), scheduled to shift from 1 to 10 BPS on March 6, 2025. It is not recommended for production mainnet miners, but non-mining mainnet nodes may upgrade for early stability testing. Note that this version does not support TN11—those needing TN11 should remain on the latest stable release or stable branch.

For detailed instructions on setting up a TN10 node, generating transactions, and mining with this release, see the TN10 Crescendo Hardfork Node Setup Guide.

Stable Release - v0.16.1

• Implement UTXO Return Address RPC command by @coderofstuff in #436
• fix clippy, bump wasm dependencies by @biryukovmaxim in #624

Stable Release - v0.16.0

Instructions for Node Maintainers

This is the first stable release that includes the database version upgrade introduced in #494. When you run this version with an existing datadir, you may be asked to upgrade your database version in CLI. To proceed, type y or yes and hit enter. Alternatively, you can run this version with a --yes flag to skip the interactive question.

This database upgrade is a one-way path, which means after updating your datadir to the new version, you won't be able to go back to an earlier version.

Database Upgrade to v4

This release includes a database upgrade from v3 to v4. This upgrade includes:

• introducing new data stores for temp ghostdag stores used when building pruning proofs
• removing deprecated higher level ghostdag data entries - these are now calculated on-the-fly when needed (validating pruning proofs, building pruning proofs)
