Source hash:f9206836b5Remaining commits: 1 <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Medium Risk** > Changes how `SingletonFastForward` updates its internal `fast_forward_spends` state, which can affect subsequent mempool validation/fast-forward chaining for singleton spends. Risk is moderate because it touches spend/lineage handling but is a small, localized logic change. > > **Overview** > Ensures `SingletonFastForward.process_fast_forward_spends()` **accumulates fast-forward lineage updates in a local `ff_state_update` map** while processing a mempool item, and only merges them into `self.fast_forward_spends` at the end. > > This also fixes the *no-fast-forward* path: when a spend is already the latest singleton version, the derived “next version” lineage is now persisted (via `self.fast_forward_spends.update(...)`) instead of being dropped on early return. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commitfdd11aaf6a.

Chia is a modern cryptocurrency built from scratch, designed to be efficient, decentralized, and secure. Here are some of the features and benefits:
- Proof of space and time based consensus which allows anyone to farm with commodity hardware
- Very easy to use full node and farmer GUI and cli (thousands of nodes active on mainnet)
- Chia seeder, which maintains a list of reliable nodes within the Chia network via a built-in DNS server.
- Simplified UTXO based transaction model, with small on-chain state
- Lisp-style Turing-complete functional programming language for money related use cases
- BLS keys and aggregate signatures (only one signature per block)
- Pooling protocol that allows farmers to have control of making blocks
- Support for light clients with fast, objective syncing
- A growing community of farmers and developers around the world
Please check out the Chia website, the Intro to Chia, and FAQ for information on this project.
Python 3.10+ is required. Make sure your default python version is >=3.10 by typing python3.
If you are behind a NAT, it can be difficult for peers outside your subnet to reach you when they start up. You can enable UPnP on your router or add a NAT (for IPv4 but not IPv6) and firewall rules to allow TCP port 8444 access to your peer. These methods tend to be router make/model specific.
Most users should only install harvesters, farmers, plotter, full nodes, and wallets. Setting up a seeder is best left to more advanced users. Building Timelords and VDFs is for sophisticated users, in most environments. Chia Network and additional volunteers are running sufficient Timelords for consensus.
Installing
Install instructions are available in the Installation Details section of the Chia Docs.
Running
Once installed, an Intro to Chia guide is available in the Chia Docs.
