Enum pallet_transaction_storage::pallet::Call

pub enum Call<T: Config> {
    store(Vec<u8>),
    renew(T::BlockNumber, u32),
    check_proof(TransactionStorageProof),
    // some variants omitted
}

Contains one variant per dispatchable that can be called by an extrinsic.

Variants

store(Vec<u8>)

Index and store data on chain. Minimum data size is 1 bytes, maximum is MaxTransactionSize. Data will be removed after STORAGE_PERIOD blocks, unless renew is called. #

• n*log(n) of data size, as all data is pushed to an in-memory trie. Additionally contains a DB write.

renew(T::BlockNumber, u32)

Renew previously stored data. Parameters are the block number that contains previous store or renew call and transaction index within that block. Transaction index is emitted in the Stored or Renewed event. Applies same fees as store.

• Constant.

check_proof(TransactionStorageProof)

Check storage proof for block number block_number() - StoragePeriod. If such block does not exist the proof is expected to be None.

• Linear w.r.t the number of indexed transactions in the proved block for random probing. There’s a DB read for each transaction. Here we assume a maximum of 100 probed transactions.
