  • Domain events result from domain experts' insights, representing significant domain occurrences.
  • Event names should align with the domain's ubiquitous language, reflecting past command operations.

  • XXHash offers speed with non-cryptographic collision resistance, unsuitable for destructive actions.
  • SHA-256 is collision-resistant and ideal for audits, legal cases, and backup verification.
