hiero-ledger/hiero-block-node v0.29.0

on GitHub

Hiero Block Node v0.29.0 marks a landmark milestone: TSS (Threshold Signature Scheme) Wraps verification is now live on the block verification path. 🎉 This is the first release where the Block Node can cryptographically verify TSS-signed blocks produced by Consensus Node v0.72.0, closing the loop on end-to-end block integrity for the modern Hiero network. Alongside TSS integration, verification is updated to full HAPI v0.72 compatibility, and a critical bug in allBlocksHasher — which caused incorrect hash state for the first non-genesis block and during backfill — has been fixed. To support the larger block items that TSS Wraps produce, the default and maximum maxMessageSizeBytes has been raised to 36 MB, PBJ has been upgraded to 0.14.2, and maxIncomingBufferSize is now configurable, ensuring the node can handle oversized TSS wrap block items without dropping messages.

This release delivers meaningful improvements across several areas. The Server Status Detail API now exposes stream protocol version and block range availability. The Stream Publisher Plugin gains support for the EndOfBlock message. The Files Historic Plugin now enforces an unchangeable setting for files-per-zip to prevent misconfiguration mid-operation, and retention logic has been refactored for reliability. The Files Recent Plugin sees IO capability improvements. The CLI tools gain a --network flag for multi-network support, hex parsing is fixed for 0x-prefixed inputs, and CLI block wrapping performance is improved. The wrapped block validator gains balance validation and token tracing support for post-October 2023 states with saved states. Sidecar file parsing limits are increased from 2 MB to 8 MB using the correct 5-argument parse call, and subdirectory structure is now preserved in temp block files for tar.zstd archives. A reduced memory profile (nano) is also available for resource-constrained environments.

On the infrastructure side, the plugins PVC now follows the same provisioning pattern as other PVCs, and explorer deployment is skipped in all solo E2E topologies to reduce test overhead. Fourteen dependency upgrades — including Mockito, Protobuf, Dagger, Docker actions, and GitHub Actions tooling — round out the release.

Important Notes

Compatibility: TSS Verification

v0.29.0 introduces live TSS Wraps verification. To benefit from full end-to-end verification, your deployment must meet the minimum version requirements below. Running with older Consensus Node or Mirror Node versions is still supported for non-TSS block processing, but TSS block verification requires the versions listed.
