Problem

The dashpay/insight image can't follow Dash Core's V24 hard fork. Today's 4.0.10 image bundles dashcore-node 7.0.5 and Insight API 4.0.8, both on @dashevo/dashcore-lib 0.22, which can't read the CbTx v4 coinbase that every block carries from activation. On the first post-activation block the explorer process dies on an uncaught exception, and the block list fails. Mainnet V24 signalling starts today (2026-11-09), and the earliest activation is in late November.

The image also built against whatever was newest at build time: dashcore-node master and the newest 4.x Insight API. A rebuild could therefore ship a different backend than the one that was tested.

Fix

• Pinned backend: the image now uses dashcore-node v7.0.6 (fix: keep Insight working after the V24 hard fork (CbTx v4 coinbases) dashcore-node#109) and @dashevo/insight-api@4.0.9 (fix: keep Insight API working after the V24 hard fork (CbTx v4 coinbases) insight-api#109), the first releases that read V24 blocks. Both can be overridden with the build args DASHCORE_NODE_REF and INSIGHT_API_SPEC.
• Version and docs: the package version goes to 4.0.11, and the README now states the Dash Core v24 and index requirements.
• CI: moved off the retired ubuntu-20.04 runners. The release jobs now use action versions that still run, and the unused MAJOR_VERSION build arg is gone.

There are no UI code changes; the UI doesn't read the CbTx version.

Proof

• Image build: I built the image from this Dockerfile with the two companion branches substituted for the pinned releases. Inside the image, dashcore-node is 7.0.6, Insight API is 4.0.9, and both resolve a single @dashevo/dashcore-lib 0.26.1.
• Functional test: fix: keep Insight API working after the V24 hard fork (CbTx v4 coinbases) insight-api#109's test passes against Dash Core 24.0.0 on regtest across a V24 activation, and the same test crashes the stock stack.

Merge order

This needs the dashcore-node v7.0.6 tag and @dashevo/insight-api@4.0.9 on npm, so it merges after those two releases. The v4.0.11 release then publishes dashpay/insight:4.0.11.

Summary by CodeRabbit

• Documentation

  • Added compatibility requirements for Insight 4.0.11 and later, including the minimum Dash Core version and required indexes and ZMQ topics.
  • Clarified that older Insight and Dash Core versions may not process blocks or follow the network after the v24 hard fork.

• Deployment

  • The Docker image now uses specified Dash Core Node and Insight API versions rather than tracking the latest code.

Walkthrough

The package version advances to 4.0.11. The workflow updates its runners and GitHub Actions versions. The Docker image build pins dashcore-node and Insight API versions. The README documents compatible Dash Core versions, required indexes, ZMQ topics, and Docker image pins.

Changes: Release and Docker image

Layer / File(s)	Summary
Package version and test/NPM release workflow package.json, .github/workflows/test_and_release.yml	The package version changes to 4.0.11. Test and NPM release jobs use Ubuntu 24.04 and updated actions. The Node version and release conditions remain unchanged.
Pinned Docker image build and release docker/Dockerfile, .github/workflows/test_and_release.yml, README.md	The Docker build uses pinned dashcore-node and Insight API versions. The workflow removes the separate major-version tag calculation and MAJOR_VERSION build argument while retaining the VERSION argument. The README adds compatibility requirements, required indexes and ZMQ topics, and pinned Docker image details.

Change: Bug fix

Suggested reviewers: shumkov, strophy

Merge Risk: Low · previous review 70471

The Docker image will build with the correct pinned backends. The README leaves manual installers without the required backend versions and with incomplete ZMQ setup instructions, which can cause startup failures or crashes in those setups. Update the README before or shortly after merge, and publish the backend releases first.

Review comments at @README.md:
- Line 7: Update the README’s backend requirements to specify dashcore-node
7.0.6 and Insight API 4.0.9 as the required versions, alongside the existing
Insight UI and Dash Core requirements.
- Line 7: Update the README’s Dash Core configuration guidance to include the
`rawtxlock` ZMQ topic and state that `zmqpubrawtx`, `zmqpubhashblock`, and
`zmqpubrawtxlock` use the same endpoint. Preserve the existing index
requirements and version guidance.
- Line 7: Update the README guidance for `zmqpubrawtx` and `zmqpubhashblock` to
distinguish the address Dash Core binds to from the endpoint Insight connects
to. Clarify that Core must bind to an address available on its host, and Insight
must connect to that endpoint using an address reachable from its own host.
