RougeChain node release 1.6.5 — AMM_INTEGRITY included, not scheduled (2026-10)

Recommended for every node. Nothing activates with this release: it carries the consensus rule AMM_INTEGRITY without an activation height, so a node that installs it validates and produces exactly as release 1.6.4 does, and a node that has not installed it keeps following the chain. Validators should install it now: the rule can only be given a height once every validator runs a release that contains it.

What changed

• AMM_INTEGRITY is in the node, unscheduled. From its activation height, pool transactions (create_pool, add_liquidity, remove_liquidity, swap) apply all-or-nothing:

  • a transaction that cannot take effect changes nothing, pays no fee and does not make the block invalid;
  • a swap route must name 2 to 4 tokens, start at the input token, end at the output token, use no pool twice, and every pool on it must exist and pay out;
  • a pair has one pool, whatever the order or letter case of the two symbols;
  • amounts are computed with checked integer arithmetic;
  • the fee of a token-to-XRGE swap is counted as collected.

  The rule and what it does not cover are described in the upgrade schedule. upgrade_schedule.amm_integrity in GET /api/stats is null on every network. The height will come in a later, announced release — testnet first.

• quantum-vault-daemon --version reports 1.6.5. The rougechain CLI is unchanged (1.3.0), rebuilt from the same commit.

Everything in release 1.6.4 is included; the upgrade schedule is unchanged (mainnet 235 / 235 / 245, testnet 1360 / 1360 / 1390, all active). This binary replays mainnet history from block 1 to the same state root as 1.6.4.

Production binary

Built twice from clean; the two builds were byte-identical. The release is described by a manifest signed with the release keys (Signed releases).

Upgrade

Nodes installed with the one-line installer and auto-update install this release by themselves (node and CLI). Otherwise:

curl -fLo /tmp/quantum-vault-daemon https://api.rougechain.io/releases/quantum-vault-daemon-amm-integrity-e433489
echo "d4ac78ef1082a0ff12af71734d67dab1caf9c5e267a7530c2264bd00f2a7da8f  /tmp/quantum-vault-daemon" | sha256sum -c
systemctl cat rougechain-validator | grep ExecStart      # the first path is the binary your node runs
BIN=/path/from/ExecStart/quantum-vault-daemon             # set this to that path
sudo systemctl stop rougechain-validator
sudo cp -p "$BIN" "$BIN.pre-1.6.5" && sudo install -m 755 /tmp/quantum-vault-daemon "$BIN"
sudo systemctl start rougechain-validator

Check after the restart: the node follows the chain as before, "$BIN" --version prints quantum-vault-daemon 1.6.5, and curl -s localhost:5100/api/stats | jq .upgrade_schedule shows amm_integrity as null.

To go back, stop the node, restore the .pre-1.6.5 binary and start it again.
