On-chain message
An immutable message was committed to the chain. The decoded payload is shown below — useful for timestamping, public attestations, or simple on-chain notarisation.
An on-chain message is arbitrary text or bytes the sender committed to the QRL chain. The message becomes part of the immutable history — useful for timestamping, public attestations, simple notarisation, or recording small references that should outlive any off-chain server. There's no protocol semantics attached to the content; reading and interpreting it is up to whoever consumes the chain.
How can I tell if this QRL transaction is fully settled?
QRL uses Proof-of-Work with cumulative-work resolution rather than protocol-level finality. The conventional rule of thumb is to wait 6-12 block confirmations on top of the confirming block before treating a transaction as fully settled. Click the block link in the action header to navigate to the confirming block, then use Prev/Next to check how many blocks have accumulated on top.
How is the fee on a QRL transaction determined?
QRL fees are sender-set: when signing, the sender picks the fee they want to attach. There is no EIP-1559 base-fee market — miners are free to pick whichever transactions they want from the mempool, but in practice they prioritise higher-fee transactions. The Fee column shows exactly what the sender chose to pay; the miner of the confirming block received the full fee.
Will the contents of this transaction ever change?
No. Once a transaction has accumulated enough confirmations its contents are effectively permanent — rewriting it would require redoing all the Proof-of-Work for every block on top, which is computationally infeasible. The XMSS signature is also unforgeable under classical and quantum threat models, so the transaction's authorship and content are anchored to history forever.
Where does this data come from?
Quantascan indexes from a QRL archive node we operate ourselves — no third-party API in the pipeline. The transaction body comes from QRL's gRPC PublicAPI (GetTransactionByHash), with sender-address resolution via GetAddressFromPK and an LRU cache so XMSS-tree roots resolve to their on-chain Q-prefix address consistently.
