Animica 7.1.0 activates two forward-only consensus changes at blocks 42,000 and 42,001. Every node operator, miner, pool participant, and exchange must be running animica 7.1.0 before block 42,000, or they will diverge from the network. 7.1.0 includes everything in 7.0.0 — if you already installed 7.0.0, please still update to 7.1.0.
pip install -U animica==7.1.0
Restart your node / miner after upgrading. Nothing else is required — the release keeps your existing wallet, chain data, and address.
Consensus address freeze. At and after block 42,000, upgraded nodes reject any block that moves funds from or to a consensus-frozen account. The freeze list contains a single address — the already-recovered ANM-2026-07 incident address — hard-coded into the release and identical on every node. The rule is forward-only and writes no state: normal blocks are unaffected; only a block that actually moves frozen funds is rejected.
15% of every block subsidy funds the Animica Foundation. Starting at block 42,001, each block’s coinbase subsidy is split 85% to the miner / 15% to the Foundation treasury. The base subsidy is unchanged — it is still 300 ANM per block this epoch and halves on the same schedule; only its division changes. Total issuance and the supply cap are unaffected. This is a public, protocol-level allocation that sustains ongoing development, security, and ecosystem work.
The Foundation treasury address is fixed in the protocol:

Why upgrading is mandatory — not optional. The reward change alters how balances are credited on every block from 42,001 onward. A node still running an older version will keep crediting 100% to the miner and will silently compute different balances from the rest of the network. This is not a loud error — blocks still validate — so an exchange, pool, or explorer left un-upgraded will quietly report wrong balances. Everyone who tracks balances must run 7.1.0 before block 42,000.
pip install -U animica==7.1.0, then restart. From block 42,001 your accounting reflects the 85/15 split; a pool left on an older version will over-credit miners by 15% relative to the network.Activation heights can be set explicitly with ANIMICA_FORK_ADDRESS_FREEZE_HEIGHT=42000 and ANIMICA_FORK_FOUNDATION_SPLIT_HEIGHT=42001. This is only needed if you cannot install 7.1.0 directly.
