Module common_validation 

Constants

ENCRYPTED_NOTE_SIZE

Expected size of the encrypted_note field in each SerializedAction. This is epk (32) + enc_ciphertext (104) + out_ciphertext (80) = 216 bytes. Canonical source of truth — drive-abci imports this constant.

Functions

validate_actions_count

Validate that the actions list is not empty and does not exceed the maximum.

validate_anchor_not_zero

Validate that the anchor is not all zeros (for transitions that consume notes).

validate_encrypted_note_sizes

Defense-in-depth: validate that every action’s encrypted_note field is exactly ENCRYPTED_NOTE_SIZE (216) bytes. This rejects malformed data early at the DPP layer before it reaches the ABCI bundle reconstruction, saving network bandwidth.

validate_proof_not_empty

Validate that the proof is not empty.
