2.5.5 Chia blockchain 2025-08-19

Note that protocol changes between node, farmer, and harvester will require all entities to be upgraded at the same time to 2.5.5. On a simple one machine setup, this will be handled by the installer. But if you have more complicated topologies with remote farmers or harvesters, you will need to upgrade all components.

Dr. Plotter is currently not compatible with Chia 2.5.5 because of the protocol changes above. Please do not update to Chia 2.5.5 until a compatible version of Dr. Plotter is released.

2.5.5 will also make changes to the blockchain database that are incompatible with previous versions. If you

2.5.5 Chia blockchain 2025-08-19

Note that protocol changes between node, farmer, and harvester will require all entities to be upgraded at the same time to 2.5.5. On a simple one machine setup, this will be handled by the installer. But if you have more complicated topologies with remote farmers or harvesters, you will need to upgrade all components.

2.5.5 will also make changes to the blockchain database that are incompatible with previous versions. If you run 2.5.5 but later wish to downgrade to an earlier version, you will need to downgrade your database schema by running the following command:

python -c "import sqlite3, sys, os; conn = sqlite3.connect(os.path.expanduser(sys.argv[1])); cursor = conn.execute('UPDATE coin_record SET spent_index = 0 WHERE spent_index = -1'); print(f'Updated {cursor.rowcount} records'); conn.commit(); conn.close()" <path to the db>

Replacing <path to the db> with your actual database path.

What's Changed

Added

• Add new error logging if the block cost fails to compute
• Add dicts to streamable

• Add Revocable CAT support to wallet (Chip 38)
• Add mempool optimizations and fixes in spend deduplication and singleton fast forward.
• Add mempool vault fast forward support
• Add unit tests to cover singleton fast forward dynamics
• Add new optional block creation algorithm to maximize transactions (set config.yaml full_node:block_creation to 1)
• Add new config setting for block creation timeout (full_node:block_creation_timeout)
• Add preparation for new plot format and expected hard fork (Chip 48)
• Add canonical CLVM serialization requirement after expected hard fork

Warning

Review the following alerts detected in dependencies.

According to your organization's Security Policy, it is recommended to resolve "Warn" alerts. Learn more about Socket for GitHub.

Action	Severity	Alert  (click "▶" to expand/collapse)
Warn		chia-blockchain@2.5.6 is a AI-detected potential code anomaly. Notes: The code is a legitimate KeychainProxy that exchanges requests/responses with a keychain daemon or uses a local Keychain. I found no indicators of deliberately malicious behavior (no obfuscation, no exec/eval, no backdoor). The primary security risk is secret exposure: the proxy reconstructs private keys from entropy/mnemonics received from the daemon, so connecting to an untrusted or compromised daemon (or misconfigured TLS) can lead to private-key disclosure. Also note the provided fragment ends abruptly ('Non'), indicating the snippet may be incomplete — review the full file in the repository before final trust decisions. Confidence: 0.90 Severity: 0.60 From: requirements.txt → pypi/chia-blockchain@2.5.6 ℹ Read more on: This package | This alert | What is an AI-detected potential code anomaly? Next steps: Take a moment to review the security alert above. Review the linked package source code to understand the potential risk. Ensure the package is not malicious before proceeding. If you're unsure how to proceed, reach out to your security team or ask the Socket team for help at support@socket.dev. Suggestion: An AI system found a low-risk anomaly in this package. It may still be fine to use, but you should check that it is safe before proceeding. Mark the package as acceptable risk. To ignore this alert only in this pull request, reply with the comment @SocketSecurity ignore pypi/chia-blockchain@2.5.6. You can also ignore all packages with @SocketSecurity ignore-all. To ignore an alert for all future pull requests, use Socket's Dashboard to change the triage state of this alert.
