Limenka releases

Prebuilt Linux binaries for the Limenka fork of Bitcoin Knots 29.3. Each release lives in a version folder under v<version>/.

What's here

• limenkad - the node daemon.
• limenka-cli - the command-line RPC client.
• limenka-qt - the graphical wallet / node.

Built for Linux x86-64 (Ubuntu 22.04), Release, with SQLite wallets. Verify a download against SHA256SUMS at the repo root.

Testnet node setup (a few minutes)

A Limenka testnet is a fresh fork-chain: mainnet genesis, trivial PoW, no seeds. Run one node and a CPU miner and you have a working chain to experiment with (including the fork's time-locked contract handling).

# 1. Make a datadir and write a config.  The fork chain is `limenka`;
#    network-specific settings go in a [limenka] section.
mkdir -p ~/.limenka-testnet
cat > ~/.limenka-testnet/limenka.conf <<'EOF'
datadir=$HOME/.limenka-testnet
chain=limenka

# 2. Start the node.
./limenkad -daemon=0 -conf=$HOME/.limenka-testnet/limenka.conf

# 3. Wait for it to be up, then start the CPU miner (one block every 2s).
while true; do
  ./limenka-cli -chain=limenka -datadir=$HOME/.limenka-testnet \
    -rpcport=19443 -rpcuser=limenka -rpcpassword=<password> \
    generateblock <your-address> "[]"
  sleep 2
done

Watch it climb:

./limenka-cli -chain=limenka -datadir=$HOME/.limenka-testnet -rpcport=19443 \
  -rpcuser=limenka -rpcpassword=<password> getblockcount

The miner mines parent-rule blocks up to forkactivationheight, then fork-rule blocks (the fork's cadence DAA, reward and delay commitment). A payment channel / time-locked contract set up on this chain resolves on the parent chain's ~600s cadence - see the Limenka README for the full testnet and contract notes.
