Is Bitcoin Traceable? What Lightning Changes (and What It Doesn't)
Yes. Every payment ever written to the bitcoin blockchain is public: anyone can look it up, see how much moved and from which addresses to which, and it stays there forever. Lightning payments work differently: they aren't written on the chain at all. But a Lightning payment isn't invisible either. To show exactly what anyone can see, we made the same payment both ways, with our own wallets, on November 7, 2026:
| On-chain | Lightning | |
|---|---|---|
| The payment | 2,500 sats from an Electrum wallet to our Alby Hub | 2,500 sats from our Rizful account to the same Alby Hub |
| On the public blockchain | Everything: the time, the amount, the fee, both addresses we paid from, our change | Nothing. The hub's channel shows once, the day it opened |
| Who else sees it | Anyone, forever | The wallet that paid (Rizful), the one that was paid (our hub), and the nodes it passed through, each seeing only its neighbours |
What anyone can see on-chain
Our Electrum demo wallet paid 2,500 sats to an address of our Alby Hub. Fifteen minutes later it was in block 974,964, and here it is on a public block explorer: mempool.space/tx/9f4e740f…7699. Nobody needs an account or our permission to read it:
- When: 2026-11-07 10:50 PST, confirmed after 15 minutes.
- The fee: 486 sats (2.34 sat/vB).
- The payment: 0.00002500 BTC, which is 2,500 sats (a sat is a hundred-millionth of a bitcoin), to the hub's address.
- The two coins that paid for it: 2,086 and 1,900 sats, from two different addresses of ours.
- The change: 1,000 sats back to a new address of ours.
How a few payments become a wallet
Bitcoin addresses don't have names on them, but they give themselves away in groups:
- Coins spent together usually have one owner. Our payment spent two coins from two addresses at once. Anyone reading it can assume both addresses are in the same wallet, and they'd be right.
- The change is yours too. The 1,000 sats that came back went to a new address, and that address is now linked to the same wallet.
- Every address shows its whole history. Click an address on a block explorer and you see everything it has ever received and sent. Click the transaction that paid it, and you go one step further back, and so on. Ours led back through the transactions we made for our stuck-transaction video. They're all our own coins, but it works the same way on anyone's.
Bitcoin.org puts it plainly: "All Bitcoin transactions are public, traceable, and permanently stored in the Bitcoin network," and "Anyone can see the balance and all transactions of any address."
How addresses get names
Mostly where bitcoin meets the real world. To buy bitcoin, or to pay for goods and services, people usually have to say who they are, which is why, in bitcoin.org's words, "Bitcoin addresses cannot remain fully anonymous." Once one address is tied to a person, everything linked to it can be too, and because the record is permanent, "something not traceable currently may become trivial to trace in the future."
Companies do this for a living:
- Chainalysis describes its work as "Mapping real-world entities to on-chain activity", with "1 billion+ addresses clustered". Its homepage says nine of the top ten crypto exchanges use it, and more than 50 regulators use its data (chainalysis.com).
- Elliptic sells compliance software "trusted by banks, exchanges and governments to screen, monitor and investigate on-chain risk" (elliptic.co).
Is crypto traceable?
Mostly, yes, for the same reason. Bitcoin, Ethereum, and stablecoins such as USDT and USDC on Tron, Ethereum or Solana all record every transfer on a public chain that anyone can read, and the same companies analyse them.
What Lightning changes
Our Alby Hub made an invoice for 2,500 sats with the note "Lightning test payment", and our Rizful account paid it from a phone. It landed in about a second. Then we looked for it on the chain, and there was nothing to find.
Lightning payments aren't written on the chain. They move inside payment channels between Lightning nodes. Our hub has one channel, from Megalith, and the only part of it on the blockchain is the day it opened: November 1, 2026, a single output of 1,000,000 sats. Since then more than fifteen payments have gone in and out of the hub over that channel, including this one, and the chain shows none of them: the output hasn't been spent. A channel only shows up on the chain when it opens and when it closes.
Each node sees only its neighbours. When a payment has to cross other nodes, it's wrapped in layers of encryption, one for each node, like an onion ("onion routing"). Each node can open only its own layer, so it sees the amount, the node the payment came from and the node it goes to next. It doesn't know where the payment started, where it ends, or how many nodes are on either side of it. Our page How Private Is Lightning? walks through it with diagrams.
What Lightning doesn't change
A Lightning payment is much harder to trace than an on-chain one, but some people always see it:
- The wallet you pay with. Rizful's record of our payment shows the date and time, the amount, its fees (a 3-sat platform fee and a 6-sat routing fee) and the invoice it paid. Any hosted wallet sees its own users' payments.
- Whoever you pay. Our hub has the payment, with its note.
- Anyone who sees the invoice. An invoice isn't secret. Paste one into Rizful's free invoice decoder and it shows the amount, the note, the key of the node that gets paid, and the route hints. Ours named the node just before our hub: Megalith LSP, the hub's channel partner.
- The nodes on the route. Like any node on the way, your channel partner sees the payments that pass through your channel.
- Channel opens and closes, which are ordinary on-chain transactions.
How to start
- The easy start: a free account at rizful.com, in any browser, with your own Lightning address.
- Your own node: Alby Hub, with an inbound channel from Megalith, its default channel partner. Your payment history stays on your own node.
FAQ
Is bitcoin anonymous?
No. Addresses don't carry names, but every transaction is public and permanent, addresses link to each other when they're spent together, and many get tied to people at exchanges and shops. Bitcoin.org calls bitcoin "probably the most transparent payment network in the world."
Can bitcoin be traced years later?
Yes. The blockchain is never deleted, so a payment made today can be analysed at any time in the future, with whatever new information and tools exist then.
Can a Lightning payment be traced?
Not from the blockchain: it isn't on it. The wallet that paid, the one that was paid, anyone holding the invoice and the nodes on the route each see part of it. A routing node sees the amount and its two neighbours, not where the payment started or ends.
Does a Lightning channel show on the blockchain?
Yes, twice: when it opens and when it closes. Those are ordinary transactions. The payments in between aren't.
Who can see my Lightning payments?
Your wallet provider (or your own node, if you run one), the person you pay, and the nodes your payment passes through, each of which sees only the amount and its immediate neighbours.
