QRL Block Explorer & Analytics
Quantascan is the analytics-first explorer for QRL, the Quantum Resistant Ledger — live blocks, transactions, wallet dossiers, whale flows and supply for the post-quantum mainnet.
Quantum-ready, block by block
When a large quantum computer breaks ECDSA, it'll be a headline for Bitcoin and Ethereum — and a non-event here. Every QRL block is signed with post-quantum cryptography: ML-DSA-87 on QRL 2.0, hash-based XMSS on the original Proof-of-Work chain. Zero ECDSA, nothing a quantum computer is known to break.
About Quantascan & the Quantum Resistant Ledger
QRL runs as two chains: the original Proof-of-Work mainnet secured by XMSS, and QRL 2.0 — its Proof-of-Stake, EVM-compatible successor secured by ML-DSA-87. Here's how they fit together and what Quantascan indexes for each.
The Quantum Resistant Ledger (QRL)is a blockchain built from the ground up to stay secure against quantum computers. Where most chains sign transactions with ECDSA — which Shor's algorithm could one day break — QRL uses hash- and lattice-based post-quantum signatures that have no known quantum attack. Quantascan indexes both QRL chains and turns the raw node data into live blocks, transactions, wallet dossiers, supply analytics and consensus dashboards.
QRL is the original Proof-of-Work mainnet. Every wallet signs with XMSS, a stateful hash-based scheme: each one-time signature consumes an index from a finite budget, so the chain must track signature state per address. Its addresses are 79 characters (a Q prefix plus 78 hex). It has no smart contracts — only native transaction subtypes (transfer, coinbase, token, message, slave).
QRL 2.0 is the successor chain: an EVM-compatible Proof-of-Stake network whose consensus layer (qrysm) runs on 60-second slots and 128-slot epochs. It signs blocks and transactions with ML-DSA-87, a lattice-based post-quantum signature, and its addresses are 41 characters (a Qprefix plus 40 hex). Because it's EVM-compatible it adds smart contracts, QRC-20 tokens, QRC-721/1155 NFTs, and a validator set secured by staked Quanta.
The original Proof-of-Work chain is the predecessor and is migrating to QRL 2.0. The intended model is a snapshot of its balances into the QRL 2.0 genesis allocation, after which a holder proves ownership by signing with their old XMSS wallet — verified on-chain — to release the holdings to a new ML-DSA-87 wallet. After the migration the original chain stays a permanent, read-only archive; nothing is deleted. Quantascan keeps both chains visible side by side, so you can explore QRL 2.0 whenever you need the other side of the story.
One detail you can see: post-quantum signatures are large. An ML-DSA-87 signature is ~4.6 KB and an XMSS signature ~2.5 KB, versus ~64–72 bytes for ECDSA — which is why QRL blocks are an order of magnitude bigger than a typical chain's. Watch it in the daily block-size chart, or dig into the richlist, whale movements, supply & distribution, and the full chart catalogue. Everything shown here is derived directly from QRL node data — no estimates, no off-chain guesses.
FAQ about QuantaScan
Common questions about this page
- What is Quantascan?
- A block explorer and analytics platform for QRL — the Quantum Resistant Ledger. Beyond the standard explorer features (blocks, transactions, addresses), Quantascan adds insight layers: whale tracking, wallet dossiers, supply distribution, and network health scoring.
- What's special about QRL?
- QRL is one of the few production blockchains designed to survive quantum-computer attacks. It uses XMSS post-quantum signatures rather than ECDSA. Each XMSS key has a finite signature budget — visible on every wallet's detail page.
- What's the difference between QRL and QRL 2.0?
- QRL is the original Proof-of-Work mainnet; QRL 2.0 is its successor — a Proof-of-Stake, EVM-compatible chain. The original chain is migrating to QRL 2.0 and stays a read-only archive afterwards. Use the chain switcher (top-left) to flip between them.
- How does the QRL to QRL 2.0 migration work?
- QRL 2.0 takes a snapshot of balances on the original QRL chain into its genesis allocation. A holder then proves ownership by signing with their old XMSS wallet — verified on-chain — to release the holdings to a new ML-DSA-87 wallet. The public claim spec is not finalised yet, so balances aren't linked across chains until it ships.
- Why does the data sometimes look stale?
- Quantascan indexes both chains continuously, but the source networks themselves have varying activity. If a chain hasn't seen new blocks in hours, that's reflected here honestly rather than masked behind ETA placeholders.
- Is there an API?
- Yes — the REST API serving this UI is documented under /api-docs. Read-only, public, rate-limited.
