Learn about vigilant mode.

Changed

  • The set_jwt_issuer governance action has been updated, and no longer accepts key_filter or key_policy arguments (#6450).
  • Nodes started in Join mode will shut down if they receive an unrecoverable condition such as StartupSeqnoIsOld or InvalidQuote when attempting to join (#6471, #6489).
  • In configuration, attestation.snp_endorsements_servers can specify a max_retries_count. If the count has been exhausted without success for all configured servers, the node will shut down (#6478).
  • When deciding which nodes are allowed to join, only UVM roots of trust defined in public:ccf.gov.nodes.snp.uvm_endorsements are considered (#6489).

Removed

  • SGX Platform support.

Added

  • Provided API for getting COSE signatures and Merkle proofs (#6477).
  • Exposed COSE signature in historical API via TxReceiptImpl.
  • Introduced ccf::describe_merkle_proof_v1(receipt) for Merkle proof construction in CBOR format.
  • Added COSE signatures over the Merkle root to the KV (#6449).
  • Signing is done with service key (different from raw signatures, which remain unchanged and are still signed by the node key).
  • New signature reside in public:ccf.internal.cose_signatures.
