Abstract

Appends validator deposits to the Execution Layer block structure. This shifts responsibility of deposit inclusion and validation to the Execution Layer and removes the need for deposit (or eth1data) voting from the Consensus Layer. Validator deposits list supplied in a block is obtained by parsing deposit contract log events emitted by each deposit transaction included in a given block.
