geticupayload_prior "asset_id_or_ticker" Retrieve the ICU payload from the immediately prior epoch (convenience wrapper for geticupayload_historical). Returns the previous governance document if the asset has been rotated at least once. Arguments: 1. asset_id_or_ticker (string, required) Asset ID (32-byte hex) or ticker symbol Result: { (json object) "icu_cipher" : "hex", (string) Encrypted ICU payload (holder-only assets) "canonical_hash" : "hex", (string) SHA256 of canonical plaintext "compression" : n, (numeric) Compression mode (0=none, 1=zstd) "encryption_mode" : n, (numeric) Encryption mode (0=none, 1=AES-GCM, 2=XChaCha20) "visibility" : n, (numeric) Visibility (0=public, 1=holder_only) "policy_epoch" : n, (numeric) The epoch number for this prior snapshot "icu_ctxt_commit" : "hex" (string) The commit hash for this payload } Examples: > bitcoin-cli geticupayload_prior "<asset_id>" > bitcoin-cli geticupayload_prior "GOLD"
