(** This module handles hashes of implicit contract addresses used for
    commitments in the origin block.

    This module is needed because for legal reasons, when the blockchain is
    activated, the btz1 addresses of participants to the fundraising are not
    listed directly but instead their hashes are listed, together with their
    balances. Thus, the listed accounts can be activated and credited in the
    activation block. *)
