keep-network/keep-ecdsa v1.6.0

Client: 1.6.0 (Mainnet)

on GitHub

Overview

This release brings two important improvements to client functionality.

First, the ECDSA client now prints Ethereum addresses of operator nodes who announced their presence and signaled readiness during key generation and signing. This change helps to diagnose and react to potential problems before hitting a timeout.

Second, the ECDSA client now has the ability to monitor pre-params pool size for a key generation as one of the metrics exposed. This feature helps to profile the performance of the machine the client is running on and to diagnose potential performance problems.

There are also several smaller bug fixes and improvements, detailed below. Note that the client version can be updated without any config changes, and config changes can be made separately.

Details

v1.6.0 is the latest release of Keep ECDSA client, which primarily drives ECDSA keeps. The most important client changes since v1.5.0 are:

• Improved logging during presence announcement and readiness signaling phases of key generation and signing. Ethereum addresses of operators who properly announced their presence and signaled readiness are logged on INFO level. Ethereum addresses of operators who failed to announce their presence or signal readiness are logged on ERROR level.
• Config file values for BalanceAlertThreshold and MaxGasPrice can now be provided in wei, Gwei or ether units. More details on units are available in the sample configuration file.
• Key generation pre-params target pool size can now be configured based on the server's performance and key-generation request peaks it is expected to handle. More details on configuring pre-params target pool size are available in the sample configuration file.
• Key-generation pre-params target pool size is now available as one of the client's metrics.
• Fixed bug about not exiting public key submission monitoring loop when the maximum number of retries has been reached.
• Reduced a signature publication delay to 90 seconds to adjust expected transaction confirmation times to reality and improve the clarity of logs.

In addition to the information above, we're providing two pieces of information for operators and other interested parties:

• The Docker Hub image hash.
• The release commit hash.

Docker image is available as docker pull keepnetwork/keep-ecdsa-client:v1.6.0; sha256sum is sha256:0290c708bb643e7e8c0f52bd64eb4f995e3253389ab8f33e902ffef575bd9a0a.
