…lishes an onion service Adds core.tor to the config: when enabled, a Tor container joins Core's network namespace, Core dials onion peers through its SOCKS port and registers its own v3 onion service over the control port. Clearnet traffic is not proxied, so quorum traffic stays direct and the masternode keeps its IPv4 identity, which Core still requires. The onion address is reported by dashmate status core.

…ded nodes The migration that adds core.tor now enables it and gives each node its own control password, so an existing node gets onion connectivity on its next update or start with no setup step. The setup prompt defaults to Yes and the local preset enables it unless --no-enable-tor is given. Opt out with core.tor.enabled=false. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Local QA completed on 2026-09-08 against The full CLI phase used the actual Dashmate entry point and real containers throughout; lifecycle tasks were not mocked or invoked directly. Core RPC and Docker inspection supplemented the CLI results. Automated validation at the fixed head
Actual CLI flows
Before cleanup, all four local Core nodes agreed at height 1041. All three masternodes were READY, each with PoSePenalty 0 and PoSeBanHeight -1. All three Platform nodes were up at height 3. Separate real Docker lifecycle checks at the fixed head also verified that stop removes disabled Tor without affecting another node, up starts Core without Tor, re-enabling restores the onion identity, and up alone removes an existing disabled Tor orphan. That isolated fixture excluded the helper; the full CLI run above included the helper and Platform. Earlier independent checksOn the original reviewed head,
Environment and limitsmacOS arm64; OrbStack Docker 29.4.0; host Node 26.5.0; Core 23.1.8; pinned Tor 0.4.9.11; Tenderdash 1.7.0; published Drive/DAPI 4.2.0-dev.8 images. The published helper predates this PR, so the supported helper-build configuration used a temporary Dockerfile to copy the exact committed Dashmate package onto the matching published helper runtime/dependencies. Local environment adjustments were necessary: correcting the temporary helper Dockerfile path, restoring source read/traverse permissions for its non-root user after restrictive-umask archiving, reconnecting one Tenderdash container to its existing network after a transient Docker port-binding failure, and assigning dedicated testnet ports because the default RPC port reached another local service. OrbStack's special host address This covers the Tor-related CLI lifecycle, not every Dashmate command or a production soak. Both testnet nodes downloaded real blocks (over 205,000 and 284,000 respectively) but did not complete initial synchronization. No funded mainnet node was touched.

Dashmate-managed masternodes and evonodes have no way to take part in the Tor side of the Dash P2P network. This adds a Tor sidecar, offered with Yes selected by default during setup, so Core can reach
.onionpeers and publish an onion service of its own for inbound connections.This is a dual-stack feature. The node keeps its public IPv4 address, and the ProTx address is unchanged. Dash Core requires an IPv4 address in the masternode registration and checks it against its local address at startup (
src/active/masternode.cpp), peers only ever dial the primarycore_p2pentry, Platform parses the masternodeserviceas aSocketAddrand Tenderdash dials plain TCP. An onion-only masternode therefore needs Core, rust-dashcore, Drive and Tenderdash changes and V24 activation first. This PR gives operators the part that works today: onion connectivity on top of the IPv4 identity.What was done?
core.torwithenabled(defaulttrue),docker.image(osminogin/tor-simple:0.4.9.11pinned by its multi-arch index digest) andcontrol.password(random on setup). Schema, base defaults, and a migration keyed4.2.0that backfills the section withenabled: falsefor existing configs. Upgrades do not silently enable Tor; any existing Tor settings are preserved.docker-compose.tor.ymloverlay, included bygenerateEnvswhen enabled. Thecore_torservice runs withnetwork_mode: service:core, so Tor's SOCKS and control ports live on Core's loopback and nothing Tor-related is reachable from the host or other containers. Tor state is a named volume.templates/core/tor/torrc.dotrendersSocksPort 127.0.0.1:9050,ControlPort 127.0.0.1:9051and aHashedControlPassword. The hash is computed insrc/tor/hashTorControlPassword.js(Tor's iterated-salted S2K) and verified againsttor --hash-passwordoutput in a unit test, so the plaintext never appears in torrc.dash.confgainsonion=127.0.0.1:9050,listenonion=1,torcontrol=127.0.0.1:9051,torpassword=…when enabled, andlistenonion=0when disabled.proxy=andonlynet=are deliberately not set: clearnet peers and quorum traffic stay direct, so enabling Tor cannot cause PoSe penalties from exit latency.

The published amd64 layer contains no setuid files or scripts, and its/usr/bin/toris byte-identical (sha25623ea7c64…) to a fresh install of Alpine'stor-0.4.9.11-r0package. The image carries buildkit SLSA provenance naming the GitHub commit it was built from. It is not signed, so the digest pin is what makes it immutable.How Has This Been Tested?
Local validation after the migration change: all 828 Dashmate unit tests pass, including upgrades from 0.25.0 and 4.1.x that leave Tor disabled, distinct generated control passwords, preservation of existing enabled and disabled Tor settings, and unchanged enabled defaults for new configs. The Oclif CLI manifest builds successfully. Targeted ESLint passes with no errors (one pre-existing unused-disable warning). Generated workspace dependencies were restored from this PR's successful CI build.

core.torwithenabled: falsewhen the section is absent, so starting an upgraded node does not launch the Tor sidecar. Operators can opt in withdashmate config set core.tor.enabled truefollowed bydashmate restart. Configurations that already contain Tor settings retain them. The regression tests cover these choices; the earlier end-to-end upgrade test enabled Tor automatically and no longer describes this PR's behavior.Supersedes #4617 (same branch from a fork, where the image build and Dashmate E2E jobs were skipped for lack of repository secrets). Both CodeRabbit findings from that PR are addressed here: the
config createpassword fix in the last commit, and the migration clone concern was a false positive (Config.getStored()deep-clones).Breaking Changes
None. New mainnet/testnet setups ask whether to enable Tor with Yes selected by default;
--no-enable-toropts out. Local setups enable it unless explicitly disabled. Upgrades leave Tor disabled when adding the section and preserve existing choices.Checklist:
