The official Merkle Service repository released a series of updates on July 9, moving from v0.4.1 through v0.4.4. The release notes include fixes to source the BLOCK_PROCESSED merkle root and coinbase from the fetched block, fail over across DataHub peers when fetching subtree 0 for coinbase BUMP construction, correct coinbase-BUMP composition for lifted final subtrees, prefer Teranode’s ready-made BUMP, and reject announcements with invalid DataHub URLs as permanent downstream failures.

Merkle Service is described as a high-throughput BSV Blockchain merkle-proof delivery service for subscribers. Its repository says clients register a transaction ID and callback URL, while the service watches the BSV network over P2P and posts lifecycle updates and STUMP proofs back to subscribers as transactions are observed and mined. (GitHub)

The project is designed to interoperate with Teranode and ARCADE, using STUMP-based compound proofs, horizontally scalable pipeline stages, pluggable storage backends, and Teranode-compatible P2P handling. (GitHub)

BSV TIMES read:
This is a technical update, but an important one for the infrastructure layer. Merkle proofs, BUMPs, STUMPs, subtree handling, and callback delivery are part of the verification path that applications need as BSV Blockchain scales. The release series should not be treated as a new public performance claim. Its importance is reliability: proof delivery needs correct roots, correct coinbase handling, resilient peer fallback, and safe rejection of invalid downstream announcements.
