Just like the validator keys, the withdrawal keys also consist of two components: Losing this key before updating withdrawal credentials to 0x01 type means losing access to the validator balance. When combined with additional data, the mnemonic generates a hash known as the 'master key'. SHA256 hashing algorithm is applied to the entropy . Thanks for contributing an answer to Ethereum Stack Exchange! The mnemonic phrase can be converted to a number which is used as the seed to a deterministic wallet that generates all the key pairs used in the wallet. Instead, multiple validator keys can be derived from a single common secret and storing that single secret allows access to multiple validator keys.
