Hive Blockchain Detailed Change Log: v1.27.0 to v1.28.0

This detailed log outlines the key features, bug fixes, and preparatory changes introduced in incremental releases leading up to the v1.28.0 release, which includes Hardfork 28 (HF28).

⚠️ Important Upgrade Notice

Upgrading to 1.28.0 will typically require a full node replay due to changes in the internal hived state format and data structures.

New options impacting behavior:

  • block-log-split - defaults to 9999 to support splitting the block_log file into multiple "part" files (each part file stores 1 million blocks). If you wish to preserve the previous monolithic block_log file behavior, set this option to -1.

    Splitting the block_log file into multiple part files allows you to relocate part files on different filesystems and symlink them in the blockchain directory. This means that multiple hived nodes can use a single set of part files to share most of the block log history (once a part file is filled with 1M blocks, it is never written to again).

    If the default block-log-split value is lowered, nodes will operate in a "pruned" mode, only keeping the latest N 1M block parts. In the extreme case of setting block-log-split to 0, the node will not keep the raw contents of any blocks.

    Operating in pruned mode saves disk space, but also reduces the node's ability to support block_api usage (API for fetching historical blocks) and provide old blocks to other nodes that are syncing from scratch.

    Note for updating an older version of hived: the hived tool will automatically perform a block_log split of an existing monolithic block_log file when the block-log-split option is changed from monolithic (-1) to any other value, including the new default value of 9999. This will temporarily require double the normal storage during the time the file is being split into part files. If you wish to avoid this, you must explicitly set block-log-split to -1 before starting the upgraded node.

  • comments-rocksdb-path - option to specify location of the external storage database directory for comments (this is state data that was previously stored directly in the shared memory file). Defaults to comments-rocksdb-storage subdirectory in the shared memory directory. You can specify an absolute path to place it in a separate directory from the one used to store the shared memory file (and thus reduce the ramdisk size required to most efficiently perform replay or sync operations).

  • changes related to options useful for testing like stop-replay-at-block (renamed to stop-at-block also allowing to stop processing at block received from sync), exit-at-block allowing to stop hived process after receiving given block

🚀 I. Hardfork 28 (HF28) - Protocol Consensus Changes

These changes were implemented in the 1.27.x branch and are scheduled to be activated upon reaching the HF28 block.

Feature Area Change / Details MR/Issue Reference
Block Size Limit Witness-configurable block size is capped at 2MB. Merge Request 1357
Transaction Expiration Increased the transaction expiration time for better network resilience. Merge Request 1383

Authority Checks Stricter authority matching is enforced (e.g., an active authority can no longer satisfy a posting level requirement). Merge Request 1408, Issue 716
Signature Flexibility Redundant (ineffective) signatures are allowed. Owner/active/posting authorities required by mixed operation types can be combined in a single transaction. Merge Request 1420
Vote Limits Vote edit limits are eliminated on posts. Issue 458
Recurrent Transfers Multiple recurrent transfers are allowed for the same sender/receiver pair. Issue 382

Release notes

Minor release. DOES NOT REQUIRE hardfork yet.

Warning: this update changes hived state format and requires hived node replay, if you are using version 1.27.6 or earlier.

Configuration option changes

  1. The default behavior of options has changed. Previously, an option's default value would only take effect when the config.ini file was generated for the first time. In that case, the file contained explicit option assignments based on their defaults. This was misleading because it was impossible to determine later whether an option was intentionally set by the user or simply left as the default.
    Now, options without explicit assignments in the config.ini (or in application command line argument list) have internally set default value regardless of config.ini presence.

  2. Changes made in the hived configuration option set:

    1. Added new options specific to performance tweaks (to prevent transaction flood):

    2. Added option to configure a block log splitting:

      • block-log-split, defaults to 9999 and allows to automatically split monolithic block log file into 1M block chunks.

      Please note that this behavior can be troublesome if your environment has limited disk space (you need temporarily twice the size of block_log to split it).

      If you want to keep old behavior (monolithic block_log), please set this option to -1.

    3. Simplified usage of transaction status plugin and change its options:

      • removed transaction-status-track-after-block,
      • removed transaction-status-rebuild-state,

      Right now transaction status plugin relies only on transaction-status-block-depth and head block number estimation so it activates tracking automatically according to chosen depth.

    4. Removed deprecated hived plugins: follows and tags

    5. Eliminated options for deprecated plugins: https://gitlab.syncad.com/hive/hive/-/issues/649

    6. Changed p2p plugin options:

      • removed seed-node in favor to p2p-seed-node
      • removed force-validate in favor to p2p-force-validate

    7. Changed webserver plugin options:

      • rpc-endpoint option removed in favor of: webserver-http-endpoint or webserver-ws-endpoint

    8. Changes in the set of options useful for testing:

      • stop-replay-at-block has been changed to stop-at-block which also allows to stop during p2p sync (i.e. not only during replay).
      • exit-before-sync option has been replaced by exit-at-block which also allows to exit during p2p sync.
      • Removed debug plugin edit-script option

Functional changes

Implemented HF28 changes (even this version does not activate the Hardfork)

  1. Improved witness properties update (new values appeared too early) https://gitlab.syncad.com/hive/hive/-/merge_requests/1360
  2. Max block size configuration (by witnesses) can't exceed 2MB value: https://gitlab.syncad.com/hive/hive/-/merge_requests/1357
  3. Increased transaction expiration time: https://gitlab.syncad.com/hive/hive/-/merge_requests/1383
  4. Authority verification changes:
  5. Voting power changes: https://gitlab.syncad.com/hive/hive/-/issues/609
  6. Eliminate vote edit limits: https://gitlab.syncad.com/hive/hive/-/issues/458
  7. Recurrent transfer changes:
  8. Fixes related to decline_voting_rights operation: https://gitlab.syncad.com/hive/hive/-/issues/441

HF28 has been scheduled to 08. February 2025 13:00 UTC, although to make it possible another (1.28.0) version must be published. It is planned to make it backward compatible to this one (containing only version change).

New features

  1. Support for pruned block log. Hived configuration options allows to store blocks in local blockchain subdirectory as:
    • monolithic file (as previously: single block_log file),
    • split into 1M block parts what allows you to relocate files across different filesystems and symlink them in the blockchain directory
    • prunned to store latest N 1M block parts (including 0 to avoid block storage at all) Block log prunning allows to save disk space, but also reduces ability to support block_api usage and P2P communication. The hived tool is also able to perform automatically block_log split when configuration change from monolithic to split storage. The block-log-split option defaults to 9999 to enable split mode in the block storage. block_log_util tool also has been extended by support of file splitting.
  2. Hived API supports keep-alive connections: https://gitlab.syncad.com/hive/hive/-/merge_requests/1363
  3. Configuration ability preventing hived node flooding. See previously mentioned options for details.

Functional and performance improvements

  1. Better error handling in case of missing disk space to store shared memory file. Allows to see error at hived startup, instead of at random time when actual memory allocation failed during runtime processing. See https://gitlab.syncad.com/hive/hive/-/merge_requests/1372 for details

Bug fixes

  1. Fixed api_account_object::post_voting_power value returned by all database_api methods providing account properties (like find_accounts - previously hived returned incorrect data. See https://gitlab.syncad.com/hive/hive/-/merge_requests/1401 for details
  2. Fixed operation JSON format returned by condenser_api methods: https://gitlab.syncad.com/hive/hive/-/merge_requests/1381
  3. Fixed database_api.verify_account_authority call: https://gitlab.syncad.com/hive/hive/-/merge_requests/1328/diffs?commit_id=3156ddf4bf16e2f0b4742762115651010621dac3
  4. condenser_api.verify_account_authority adjusted to above changes
  5. Some DGPO properties have been updated too early: https://gitlab.syncad.com/hive/hive/-/merge_requests/1360
  6. Eliminated crash at resync: https://gitlab.syncad.com/hive/hive/-/merge_requests/1367
  7. Eliminated multi threading issues in witness plugin: https://gitlab.syncad.com/hive/hive/-/merge_requests/1268
  8. Hived shutdown fixes: https://gitlab.syncad.com/hive/hive/-/merge_requests/1418
