Deep Dive
1. Remote Wallet & Hardening (26 March 2026)
Overview: This major update introduces a Remote Wallet feature, allowing users to sign transactions from a separate, secure device. It also includes a comprehensive set of security and performance improvements to make the network more robust.
The release is a "soft fork," meaning all node operators must upgrade to continue participating in consensus. The key addition is the new Remote Wallet RPC calls, which enable a safer signing process by isolating private keys. Alongside this, the update includes "numerous hardening measures" such as improved connection handling, stricter message validation, and a defensive mempool for slower machines. It also includes a bump to the underlying chia_rs library for better stability.
What this means: This is bullish for XCH because it significantly improves the security of the network and user funds. The new remote wallet feature makes it safer to manage keys, while the general hardening makes the entire blockchain more resistant to attacks and failures, leading to greater trust and reliability.

2. Preliminary PoS2 Support (12 November 2025)
Overview: This update begins to lay the technical groundwork for a future, more efficient plot format known as PoS2 (Proof of Space 2). It also delivers improvements to the mempool's speed and reliability.
The changes include a new inner puzzle meta-standard for wallets and optimizations to the transaction queue algorithm. The release also removed support for older software versions (Python 3.9) to streamline development.
What this means: This is a forward-looking, neutral update that prepares the network for future advancements. It doesn't change how users farm today, but it sets the stage for potential future efficiency gains in plotting and farming, which could lower barriers to entry in the future. (Source)
3. Security Fix & Protocol Updates (1 May 2024)
Overview: This release focused on a security fix for the blockchain and introduced new Chialisp "message conditions," which are essential building blocks for more complex and secure smart transactions on the network.
The update included a patch for an undisclosed security issue. It also implemented CHIP-25, which created new Chialisp conditions that ensure a specific set of coins are spent together, preventing certain types of smart contract errors.
What this means: This is bullish for XCH because it directly addresses security vulnerabilities, making the network safer for all users and developers. The new message conditions enable more sophisticated and reliable decentralized applications (dApps) to be built on Chia, expanding its potential use cases and ecosystem. (Source)
