Each consortium pins a single compose-hash; KMS only releases per- dataset keys when every owner has signed off through the multi-sig DstackApp owner.

Mühürlü veri kaynağında kalır · model seyahat eder · çoklu sahip onayı her anahtar sürümünü kapıdan geçirir
Her sahip yerel bir sealing CLI çalıştırır: HKDF(kms_root_pubkey, analysis_app_id, analysis_compose_hash, owner_id). Veri setini şifreler, ciphertext yayınlar. Sahipler asla plaintext veya key göndermez. Tarifi değiştirin → key artık eşleşmez.
CLI · mühürleme
Each owner runs the local sealing script (HKDF-derived wrap-key bound to the analysis compose-hash). Plaintext never leaves the silo; only ciphertext + a recipe-bound envelope is published.
Onay konsolu
Owners review the public compose-hash, then sign the multi-sig that owns DstackApp. Threshold-of-N before any key is released.
REST + Sign-RPC
Submit the analysis compose, fetch the signed aggregate. Every response carries a Sign-RPC envelope chained to TDX root + on-chain DstackApp.
CVM içinde Python
Inside the analysis CVM, unwrap_dataset() asks dstack-guest-agent for per-owner keys. Joins, embeddings, and model passes — all in TDX-encrypted memory.
sealed dataset · cohort-A.tar
1.6M rows
Each owner's wrap key is HKDF(kms_root, app_id, compose_hash, owner_id). Change the recipe and the key changes — old ciphertext is permanently locked out. The wrap key itself only re-derives inside an attested CVM whose compose-hash matches.
DstackApp.sol · 0x73c2…be09
multi-sigDstackApp.sol holds the compose-hash. KMS only releases per-owner keys when every required owner has signed off through the multi-sig. Any single owner can revoke globally with one on-chain transaction — no coordination needed.
