Bitcast X 2.1.0

Bitcast X 2.1.0 adds a stable application boundary for creator products while keeping the miner-validator protocol version independent.

Highlights

• Complete authenticated /api/v1 miner application API: qualification, ecosystems, leaderboard, campaigns, eligibility, claims, submissions, campaign results, and reward recommendations.
• Stable collection and error envelopes, required idempotency keys, and external reconciliation IDs for safe product integration.
• Explicit compatibility policy: v1 fields and semantics remain supported; incompatible changes require a new path version and an overlap window.
• Prompt version 1 now performs generic brief-instruction compliance; prompt versions 2 and 5 remain supported and byte-stable, while retired versions 3 and 4 are rejected.
• Qualification uses the release-bundled Finney schedule and counts all subnet alpha staked to a miner hotkey, independent of source coldkey.
• Preview publications include the v2 bonus breakdown needed for transparent pre-final scoring.

Compatibility

• Software release: 2.1.0
• Application API: /api/v1
• Existing miner-validator wire versions remain independently versioned as documented in docs/protocol.md.
