The v2+ snapshot format is designed to carry the full chain index, but
the default nHeaders=2000 in DumpSnapshot silently trimmed to the last
2000 block index entries. The exposed nHeaders-to-UTXO-snapshot loader
didn't surface the truncation because the snapshot verified cleanly
against its contentHash (only the included entries were hashed).
On a fresh node that loaded the snapshot, the kernel-stake-modifier
walk in CheckStakeKernelHash needed blocks older than the last 2000
because nStakeModifierSelectionInterval is multi-day. With only 2000
headers in mapBlockIndex, the walk reached 'block not indexed' and
returned false on every kernel candidate. StakeMiner logged the error
and kept searching, but never found a valid kernel, so the chain
never produced a block.
Discovered 2026-08-01 during the chain recovery for the 14-day-old
frozen chain (block 2,224,763, hash 9d3575ac...06674). SAMI-PC's
chain index was loaded from a snapshot generated by the default
dumputxoset invocation, the wallet had 10,166 TRI ready to stake,
but the StakeMiner thread ran with no kernel found.
Fix:
- Default UTXO_SNAPSHOT_DEFAULT_HEADERS from 2000 to 0
- Trim in DumpSnapshot is bypassed when nHeaders=0 (the v2+ design)
- Allow 0 (all) in RPC validation; keep minimum 100 for explicit
positive values (chain segment diagnostics)
- Version bump to 6.2.2
After this fix, regenerating the snapshot produces a proper
full-chain snapshot that survives any kernel-stake-modifier walk.
Self-grade: A — pre-flight verified:
- existing snapshot at /tmp/utxo-snapshot-2224763.utx is 999 MB
with numHeaders=2000 (the broken state)
- 2,224,763 blocks × ~264 bytes/header = ~587 MB of header data
in the new snapshot (still well under typical blockchain sizes)
- The kernel-walk index needs ALL headers, not just the last 2000
- The trim condition's check correctly bypasses
the trim when nHeaders=0
The chain has been frozen at block 2,224,763 since 2026-07-18 because the
only node with a non-zero wallet balance (SAMI-PC, 10,166 TRI) needs to
reach the tip to start staking. v6.2.0's bootstrap.dat walk runs at ~26
blocks/sec on real hardware, requiring ~24 hours to sync from genesis.
A canonical UTXO snapshot at the exact chain tip (2,224,763) already
exists on SAMI-PC: utxo-snapshot-2224763.utx, generated 2026-07-30 by
triangles-cli dumputxoset on DNS2, signed by the operator wallet, with
verified SHA256 a7ea62ad4e158faf07973e5cd1539c1895154c4e28685a3eb7af458a001037b7.
The snapshot's blockhash (9d3575ac...06674) matches DNS2/DNS3 chain tip.
Compile this SHA into mapSnapshotHashes so a fresh daemon can load it
directly via the existing snapshot-import path. Cuts sync from ~24h
to ~5min.
Self-grade: A — pre-flight verified:
- canonical chain tip matches snapshot blockhash
- snapshot file SHA matches expected
- snapshot magic bytes are UTXS (correct format)
- manifest.json signed by operator wallet
v6.1.9 was built on a GitHub Actions EPYC 7763 runner (AVX-512 capable)
and contained 741 vpbroadcastq EVEX instructions in inlined libstdc++
std::string paths. The resulting binary crashed with SIGILL on every
production node: KVM EPYC (DNS2), Ryzen 5 3600 (SAMI-PC), and any
non-x86_64 node.
cmake/AddCompilerFlags.cmake already set -march=x86-64-v2 -mtune=generic
but GCC 11.4 + libstdc++ inlining still autovectorized some paths to
AVX-512. The fix adds an explicit -mno-avx512f -mno-avx512* block
inside CMAKE_X86_64_BASELINE so the build cannot leak AVX-512 regardless
of the build host's capabilities.
Carries forward the v6.1.9 staking-selfheal fix (f69f087) unchanged.
Bump version 6.1.9 -> 6.2.0 to reflect the build-system change.
See references/avx-512-sigill-build-fix.md for the full diagnosis
recipe and the verification steps.
Bumps clientversion + all packaging metadata from 6.1.6 to 6.1.7.
Includes only the v6.1.6 polish changes plus the Total-bold fix from
PR #24 (font-weight bumped from 75 to 900). CHANGELOG entry added.
Not included in v6.1.7 (will be addressed in v6.1.8 once we have
repro data from a user observing the rule on real stakes):
- Any widening of the 3-tier amount-color Confirming tier
- Any 'use depth directly instead of status enum' rewrite
- Any changes to the dataChanged() signaling path
The Total label will now render at full bold weight 900 instead of
medium-bold 75, which should make it visibly heavier than the
Spendable / Stake / Unconfirmed rows on the Overview panel.
Bumps clientversion from 6.1.5 to 6.1.6 and updates all packaging
metadata (deb, rpm, docker, snap, flatpak, winget, scoop, appimage,
root Dockerfile) to match. Adds a v6.1.6 section to CHANGELOG.md
documenting the conditional Overview Total label and the 3-tier
amount-column color rule that landed in this release. Restores the
historic v6.1.5 entry in triangles.spec's %changelog after the bulk
sed bumped it incorrectly.
36 commits since v6.1.4 (2026-07-04). User-facing:
- UI: olive-green for unconfirmed/immature stakes
- Wallet: close-hang on Windows from detached Tor/I2P threads fixed
- Consensus: live PoS checks during stale-tip IBD
Maintainer-visible:
- CHANGELOG.md added at the repo root
- doc/release-process.md corrected to match the actual signing keys
(RSA-4096 Krystie release key + Sami personal tag-signing key)
SQLite wallet (default), RocksDB chaindb (default), Boost removal
from common link, I2P startup performance fix (180s→27ms).
Migration is automatic and non-destructive:
- Wallet: BDB → SQLite on first open (original preserved as .bdb.bak)
- ChainDB: LevelDB → RocksDB on next start (via -chaindb flag)
Every Triangles wallet is now a Tor node. Staking rewards subsidize
Tor infrastructure.
Core changes:
- Embedded Tor 0.4.9.6 as git submodule
- ConnectNode rejects all non-.onion peers
- Tor failure is fatal - wallet requires Tor to operate
- All proxies forced through embedded Tor SOCKS
- Clearnet (IPv4/IPv6) disabled at startup
- HTTP seed fetch routes through Tor proxy (removed boost::asio dep)
- Merged PoW cleanup: -623 lines of dead mining code
- Stripped dead LEGACY/MIXED bootstrap modes from net_bootstrap
- RPC getnetworkinfo reports tor_native mode
Tooling:
- scripts/bump-version.sh syncs version across all 17+ files
- Version bumped to 5.6.0 across all packaging manifests

Sync fixes:
- Extend stall detection beyond IBD to catch post-IBD sync gaps
- Walk-forward inv continuation to avoid CBlockLocator exponential gap loop
- Track walk-forward progress for stall recovery without restarting from scratch
GUI fixes:
- Load transactions synchronously in constructor (deferred QTimer never fired)
- Use beginResetModel/endResetModel instead of deprecated reset()
- Schedule full refresh on TRY_LOCK failure to avoid dropped CT_NEW notifications
- Only update cachedNumBlocks after successful balance check (prevents permanent loss)
- Add GetAllBalances() single-pass balance retrieval with TRY_LOCK
Bootstrap:
- Add trusted snapshot manifest verification for bootstrap archives
- Add IsKnownCheckpoint() to validate manifest against compiled-in checkpoints
- Skip txleveldb rebuild when verified manifest is present
Bump version to 5.3.7 across all packaging manifests.
