ZKas v0.3.0 — rebrand + merged mining + wallet fixes

ZKas v0.3.0 — ZKas rebrand, merged mining (tested live), wallet fixes, Windows binaries, and a bootstrap datadir for new nodes.

Setting up a new node — start from the bootstrap datadir

A fresh node syncs from a bundled snapshot (zkas-node-bootstrap-v0.3.0.tar.gz), then catches up to the tip on its own. Steps:

# 1. fresh appdir
rm -rf ./fc-node && mkdir -p ./fc-node

# 2. download the bootstrap snapshot from this release
wget https://github.com/firecash/zkas-rusty/releases/download/v0.3.0/zkas-node-bootstrap-v0.3.0.tar.gz

# 3. extract it into the appdir
tar xzf zkas-node-bootstrap-v0.3.0.tar.gz -C ./fc-node

# 4. start the node
./kaspad --appdir=./fc-node --rpclisten=127.0.0.1:16110 --utxoindex \
  --connect=185.147.157.125:16111 --connect=160.187.211.153:16111

On success the log shows current sink is … / syncing ahead from current pruning point, then a short header IBD to the tip. Use this file — zkas-node-bootstrap-v0.3.0.tar.gz — not any older bootstrap.

What's new

• Rebrand FireCash → ZKas: address HRP now emits zkas: (legacy firecash: still decodes).
• Merged mining (AuxPoW) with Kaspa wired end-to-end and tested against a live upstream kaspad. Pool accepts both zkas: and firecash: miner addresses.
• Wallet net-balance fix: sender change is no longer shown as incoming income; mempool 0-conf visibility; birthday fast-sync; per-RPC timeouts.
• Consensus hardening: is_shielded_anchor_final no longer panics on a pruned anchor source.
