What does 'registered post-quantum keys' mean?

This transaction registers a set of lattice-based public keys on chain — typically Kyber for encryption and Dilithium for signatures, alongside a legacy ECDSA key. Registering them on chain lets counterparties look up the keys before encrypting messages or verifying signatures, all anchored to the registering XMSS address.

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.
