v0.1.2
453bb17

Third mainnet release. Same network, same protocol: a 0.1.0 or 0.1.1 node keeps working, upgrade when convenient.

  • Network janzeer, protocol 3.4.0, API 1.1.0
  • Genesis hash 3a716783ee58bc56335aaede1d489eeda22cd7442c358f085a83213028b7782c
  • Native executables, no Java needed

New

  • Sync progress. GET /api/v1/info/sync reports the sync state, the committed height, how many blocks the running sync has downloaded and verified, the best known target height and the peer count. The explorer served by the node shows a banner with a progress bar while the node catches up, so a fresh node no longer looks frozen: it verifies a whole epoch before it commits the first block, which takes hours on a Raspberry Pi. /actuator/health carries the same numbers.

Fixed

  • A node restarted in the middle of its first sync could run out of memory while discarding the blocks it had staged, and then sit in PROCESSING forever without downloading anything (seen on a Raspberry Pi 3 with the default 256 MB heap). The staged blocks are now dropped with one statement, and any failure on the sync thread resets the node so the next check starts a fresh round.

Upgrade from 0.1.x

Stop the node, replace the bundle folder, keep your data/ folder (it holds config.json, your node identity), start again. Arch: sudo pacman -U janzeer-node-bin-0.1.2-1-x86_64.pkg.tar.zst && sudo systemctl restart janzeer-node. Do not restart a node that is still in its first sync unless you have to: a restart discards the staged blocks and starts the download over.
