3.1.0 Pebble Paws

Erigon 3.1.0 Pebble Paws is a significant update for node operators and validators, focusing on stability, performance, and efficiency. This release introduces several new features and optimizations, including the default enabling of receipt persistence, a smarter snapshots downloader, and numerous consensus layer improvements and official support for Shutter Network on Gnosis Chain.

Breaking changes

  • Port of external RPCDaemon now uses the same WebSocket port as the default for Erigon. (#15643)
  • Docker Images: Docker images are now based on Debian. (#16228)
  • Go Language Version: The required Go version is now golang 1.24.
  • Receipt Persistence: The --persist.receipts flag is now enabled by default (more details are provided below).
  • Pebble Paws will be the last Erigon release series to officially support Polygon.

How to upgrade

Erigon 3.1 Pebble Paws will work flawlessly with old data. For those who want to ensure they have the absolute latest data files and any recent data-specific fixes, you can optionally perform a manual data upgrade. After upgrading your Erigon binary and having done a back-up of your data directory, just run the command erigon snapshots reset --datadir /your/datadir.

Key features

Disk Footprint and Management

Several improvements furtherly reduced the size of the Ethereum archive nodes while actually storing more data, making the nodes more cost-effective and easier to manage:

  • The --persist.receipts flag is now enabled by default for Full and Minimal nodes. This downloads pre-calculated receipts, ensuring a consistent and predictable latency, meaning a more reliable system when interacting with the network, especially during high-traffic periods, and a 10x faster RPC for calls like eth_getLogs.

    • The size of the receipts is 300 GB for the Ethereum mainnet, 1 TB for the Polygon bor-mainnet, and 200 GB for the Gnosis Network. However, this can be disabled with the command --persist.receipts=false. In this case, the RPC calls will generate receipts on demand from the StateHistory. (#16040).

  • The size of .ef files was reduced by 50% with better encoding, resulting in smaller archive nodes. (#12907)

  • Rolled out phase 1 of history expiry, allowing nodes to drop pre-merge data, which significantly reduces storage requirements and simplifies node maintenance. (#15668)

  • Efficiently upgrade the existing data using the new snapshots update and snapshots reset commands, reducing node downtime and resource usage while avoiding a full re-sync.

  • Several optimization have been implemented to reduce latency, lower disk I/O, and optimize VM and snapshot operations, resulting in faster, more efficient node operation and easier maintenance (#14135, #14902, #15115, #15092, #16140).

Networking and Performance

  • Faster and more reliable syncing: the new Bittorrent web seed implementation downloads entire files in a single stream instead of making many small-range HTTP requests, resulting in faster syncing, reduced server load, improved CDN compatibility, and enhanced protection against DDoS attacks. The downloader now automatically switches sources if the snapshot set becomes inaccessible, and once the snapshot files are downloaded, they are marked as read-only to prevent accidental corruption. Torrent logging and status outputs have been upgraded, offering clearer real-time insights into sync speed, estimated completion times, and the root causes of any synchronization stalls. (#15043)

  • A new configuration flag now enables independent tuning of web seeding and peer-to-peer (P2P) download speeds, delivering more control over how data is sourced and transferred. (#15912)

  • Improved and more reliable experience with faster, more accurate RPC responses, improved error handling, and broader support for new features and tools. (#13795, #13947, #14075, #14093, #14105, #14152, #14803, #14915, #14994, #15948, #16029, #16101)

  • Smoother Polygon Network experiences with faster syncing, improved reliability, and better compatibility, thanks to a series of targeted bug fixes and optimizations. (#14056, #14080, #13845, #13807, #15595, #16160, #16035, #15538)

  • The new probabilistic filter makes historical queries much faster and more efficient. (#15960)

Protocol

  • Improved Caplin (Consensus Layer) reliability and performance with enhanced slot processing, better peer management, optimized block and attestation handling, new validator deposit toolingAore efficient reorg support. These updates provide smoother network participation, easier validator operations, and improved responsiveness. (#13825, #13858, #13883, #13893, #14158, #14128, #14913, #16084, #16083, #16219, #14890, #14875)

  • Engine API and EIP Support: This release includes new Engine API methods like GetBlobsV1 and GetBlobsV2. It also implements various Ethereum Improvement Proposals (EIPs) related to blobs and gas, ensuring compatibility with upcoming network changes. (#13975, #15420)

  • Added support for the latest protocol upgrades and features—delivering improved compatibility, security, and performance for users. (#14705, #14702, #14672, #15093, #15148, #15450, #15067, #15399, #15519, #15532, #15609, #15688, #14213)

Shutter Network

QA and Testing

Other Improvements

  • Thanks to an updated build infrastructure and streamlined release processes, deployments have improved, becoming more reliable and secure. (#13869, #15082, #15757, #16228)

  • Time-deterministic pruning loop has been introduced, making pruning steps bounded in time, improving predictability and stability, especially for large databases. (#16069)

  • Enabled the fulu devnet2 network, introducing advanced features like validator custody, earliest slot tracking, and blob recovery—empowering developers and node operators to test next-generation consensus and data availability enhancements. (#15824)
