Implementations§

source§

impl<T: Config> Pallet<T>

source

pub fn store(origin: OriginFor<T>, data: Vec<u8>) -> DispatchResult

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

Complexity
  • O(n*log(n)) of data size, as all data is pushed to an in-memory trie.
source

pub fn renew( origin: OriginFor<T>, block: BlockNumberFor<T>, index: u32 ) -> DispatchResultWithPostInfo

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.

Complexity
  • O(1).
source

pub fn check_proof( origin: OriginFor<T>, proof: TransactionStorageProof ) -> DispatchResultWithPostInfo

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

Complexity
  • Linear w.r.t the number of indexed transactions in the proved block for random probing. There’s a DB read for each transaction.
