dc4bc (Distributed Custody for the Beacon Chain) v4.0.0

Overview

Dc4bc release 4.0 is ready! The new version introduces the batch signing of 0x00->0x01 BLSToExecutionChange withdrawal credential rotation. The feature is required for the coming rotation of 18,632 validators of Lido on Ethereum Node Operators created prior to July 2021.

New Features

Batch signing: The upgraded dc4bc now enables trusted network participants to sign multiple BLSToExecutionChange in a single operation, reducing the manual effort and potential for user error involved in signing each credential individually.
