If you distribute modified versions of VoiceSign, you must:

==============================================================================
LICENSING (BUSL-1.1, AUTO-CONVERTS TO APACHE-2.0 ON 2029-05-11)
==============================================================================

VoiceSign 0.3.0+ is source-available under the Business Source License 1.1.

Permitted uses today (without a separate commercial agreement):

  - Verifying signed audio you received from others (full verifier
    ecosystem is unrestricted; this is the network effect we want).
  - Personal use: signing your own voice recordings for your own
    protection.
  - Academic research and education.
  - Integration of VoiceSign into your own product or service, provided
    that your product or service is not itself a voice-signing service
    targeted at third parties.
  - Internal use within an organization for that organization's own
    staff and members.

Uses that require a separate commercial license from Oravys Inc.:

  - Operating a commercial voice-signing service, voice-authentication
    service, or audio-provenance service that competes with services
    offered by Oravys Inc.
  - Reselling signing capacity to third parties under your own brand
    without an Oravys partnership agreement.

On 2029-05-11 (or four years after the first publicly available release
of a given version, whichever comes first) the license automatically
converts to Apache License 2.0. This guarantees the protocol becomes
true open source on a fixed schedule, while protecting Oravys's primary
business model during the bootstrap window.
