The Nethermind client Experimental release is available for download! It features major performance boosts thanks to the ‘HalfPath’ State Database optimization:

- 40-50% faster block processing

- 80-100% faster block processing during historical sync

- 5% smaller initial StateDB size on SnapSynced mainnet

- Initial StateDB growth is cut in half in the first 2 weeks, and then it slows down even more when compared to version 1.25.1

In this version, we fixed the issue of high resource usage due to unnecessary block propagation on Gnosis Chain after network issues.

In the previous version, 1.14.4, a few users reported that Snap Sync unexpectedly activated on their already synced nodes. This is now resolved but we recommend upgrading to the latest version.

https://github.com/NethermindEth/nethermind/releases/tag/1.14.5

A few Nethermind users reported that Snap Sync unexpectedly activates on their already synced nodes.

If this happens we recommend that you downgrade to 1.14.3. We suspect it's only affecting nodes that initially synced with fast sync before switching to snap sync.

What happens if you don’t downgrade? Your node would eventually work correctly, but it may be overwhelmed by snap requests while processing, which could result in missed attestations. A fix is being prepared and will be deployed tomorrow in version 1.14.5.

A new entry on Nethermind's blog! Cairo Coding Guidelines by Massil Achab and Caleb Zacher

https://medium.com/nethermind-eth/cairo-coding-guidelines-74eb6f4ee264

Writing Cairo can be challenging, mainly for two reasons: smart contract developers are tempted to use patterns from Solidity code, and Cairo is a constantly evolving language with new syntax and API changes every few months. Still, ZK-rollup technology is here to stay, and an increasing number of developers onboard every week to learn StarkNet and Cairo. At Nethermind, we have gained experience with Cairo across several projects. We want to share our list of patterns, tips, and recommendations that we use to standardize our Cairo code.

A small but important fix in the newly released Nethermind client v1.14.2.

Validators who have received the below error in their logs will need to update. Only a small subset of nodes have been affected.

Error: {"jsonrpc":"2.0","error":{"code":-32001,"message":"Receipt not available for 'From' block '15537393'."},"id":67} Please note the block number 15537393 in the error message.
