Bitcoin Forum

Blockchair.com explorer quietly started adding AML risk score and AML analysis for all bitcoin transactions and addresses without asking users!
They are not asking for any payments right now, but everyone is paying with exposing all addresses, transactions and ip addresses.
If you care at all about your privacy you should stop using this bitcoin explorer asap, especially with clearnet.
They are now promoting AML nonsense with their partners and this can only hurt everyone in the long run.

These tools are useful and sometimes it costs money. So having free information was not bad if this was only about information instead of encouraging to report addresses and help those companies to build their database. I wonder how much they are getting paid from these AML Risk Scorers and AML Analysis agencies.

Thanks for the heads up
I used to use blockchair a lot sometime back, I considered them to be a better alternative to blockchain.com, but then I discovered mempool.space and have been using that most of the time. I only visit blockchair when I want to search outside the Bitcoin network, I'll need to find an alternative for that now

It's sad to see more privacy inclined services start to implement tracking and promote the idea that Bitcoin can get tainted.

You dislike 1xbit on this forum because you know how it scammed people. Blockchair has been advertising 1xbit since many years ago and I have stopped using the site.

I visited the site today just now and I was not disappointed that the explorer is still advertising the scam gambling site.


https://talkimg.com/images/2025/07/05/UwErld.jpeg



Also you can see how malicious the site is, just because it wants to advertise those gambling sites. Get 8.75 BTC is obviously a lie to let people join 1xbit.


See other lies:

...and win up to 100 ETH. Obviously another lie.

That was then, https://www.blockchain.com/explorer later upgraded and have the features that made people on this forum left it for blockchair. I prefer https://www.blockchain.com/explorer now. But if it is about wallet, avoid Blockchain.com because it is close source.

I agree. These services are pretty useful.

I have a few addresses which I want to see the AML score. I am trying to sell/mix the lowest scores first, as things may become worse in the future.

I agree that all those things are an attack to bitcoin... But I need to be safe with my money.

Even using BISQ is risky. Because when we use BISQ we expose our identity to the buyers, and if they have problems with the AML of those addresses they can just come after me. So I don't use low AML coins (like the ones from eXch) in services like bisq.

Actually, we are accessing most of the block explorers out there they are not even asking about cookies if we allow it.
So I don't see a difference in using Mempool.space and Blockchair. Because all our data are recorded including cookies, IP and PC information, without asking the users. Anytime they can use it to monitor and check the AML and analyze them using the gather data from your PC.


I can't seems to find AML analysis dApp on the blockchair. The only thing that I could find is the privacy meter at the bottom when checking a transaction ID.
Well, I don't use Blockchair anymore; I only use them to take some few transactions and filter out.

When checking their HTML and the codes, it looks like it's just a widget of dApp gallery; it's not actually own by Blockchair; they just embedded this dApp widget just for the design.

Well, we can use a VPN and use VirtualBox to make a virtual PC with VPN when checking any of these sites to hide our identity.

Probably this AML analyzer will do get more info other than ip address and cookies, like wallet address, location/country from your ip, etc.

The showing of the widget is more like a partnership and ad for the AML analyzer, they will at least pay Blockchair for showing their site widget there, or depends on the deal.

If this is an issue to most, using VPN accessing the site will be a big help.

I have found those tools (but even others offered from other blockchain like the privacy score) completely useless.
Like the "warnings"... completely random / baseless highlights, not based on "nothing".
Because I have seen transaction from address directly associated to regular EU exchanges with "high" risk score... :(
I don't know if these "free test" are really useful at this point...

I don't know if it's paid widgets, but it looks like you are right because I've checked several transactions using different browsers, VPNs, and devices. The result under that dApp seems similar whatever you hide.
It looks like it's just a ads promoting their service on blockchair because the result is stable and when you click that box it will redirect you to their main page.

Anyway, I found the two widgets when checking addresses. It only shows on that page, but for the transaction, these two widgets are gone and replaced by the privacy-o-meter.

This is a great advice, no one should touch their clearnet website even with a Tor Browser.
There's still privacy risk with bad Tor exit nodes.

I'm also actually considering using this feature of their blockexplorer since I've been getting some UTXO from various sources with unknown origins that I've been getting "hits" on the exchange where I trade. (3x already this past three months)
Having a free service that can assess their so-called "risk score" should be useful for keeping some UTXO from being spent to platforms where 'taint' is a thing.

But I strictly won't be using theirs until they provide an '.onion' url.

I just tried an address, and the results were completely different. One returned low risk, while the other was medium (almost high) risk. I would also be very interested in knowing what is the returned results for people who actively use mixers or non KYC platforms.

What if I made a checker that basically scrapes blockchair with a bunch of proxies and IP addresses in order to throw them off?


The most frustrating part had to be that each exchange uses a different risk scoring company, so even coins that are accepted on one exchange my not be accepted on another.

I haven't used Blockchair in some time, since mempool.space is more convenient option. It seems many things have changed, including AI/chatbot addition, more ads and news aggregator. But i was curious about this feature and found 2 service show very different score.

https://i.ibb.co/xqjmTgrM/d.png (https://ibb.co/VYSH4Ckv)
Source: https://blockchair.com/bitcoin/address/bc1qmah6j6rl5lcnxev7ty7w20jgwd5hcg8hnht8sn (https://blockchair.com/bitcoin/address/bc1qmah6j6rl5lcnxev7ty7w20jgwd5hcg8hnht8sn)

While they still have detailed filter for TX, block and UTXO, i would avoid this website since those changes also make the website looks cluttered and took more time to load compared with other explorer.

That's right, and by looking at both sites, I don't really see any big exchanges using them. Everyone seems to be using either ChainAnalysis KYT or Elliptic's Navigator, so I'm not sure how useful these numbers they're showing actually are, especially if they're not going to provide more details to understand why an address has such a score.

Generally speaking, they don't like to tell people their exact reason why they classify an address in a particular way, because they claim that it will help people game the system.

Well I say that if you don't even know what makes their coins dirty (besides keeping your coins on exchanges [LOL]), then how are people supposed to stay compliant on their platform?

I've been using the Blockchair explorer for quite a few years with no issues whatsoever, because my signature campaign manager was using it, and decided to stick with it because I find it more convenient than Blockchaib.com. I noticed the AML analyzer today and didn't bother with it too much. What caught my attention is that we all share the same 21% score, is it a coincidence? What purpose does the AML analysis serve and why is the OP portraying it as a bad thing?

It doesn't matter what risk score you received, but what score was calculated by the service you are sending coins to.

Mixers like Mixtum give a very low risk score of 5-20%
At the same time, funds from no-KYC exchanges are often classified as medium risk because they are recognized as originating from an unlicensed exchange. Although traditional CEX doesn't pose a problem with receiving it. At least I haven't had such an experience.

It is good to see two services. It shows how these things make no real sense...

I even saw High risk in both services in some old addresses that I received coins from Chipmixer and sinbad (zero balance now anyway).

I keep getting an "Onion site not found" error whenever I try to access their site using Tor. Is anyone else experiencing the same issue?

After several attempts, it finally went through.

One of our customer btc coin that sent to us  :)

https://talkimg.com/images/2025/07/06/Uwkdjf.png

100% high risk by AMLCrypto.io versus 68% medium risk by MatchSystems

i believe each provider designs and applies their risk models and data sources different and not same.

I stopped using it a long time ago when they made a total redesign of their website and made it look too noisy and crowded. You literally now have to look so hard around the page to see what you want.

At the moment mempool.space is one of my favourites

I've been trying that yesterday and it also showed the same "Onion site not found" error in each attempt. (I presumed that it doesn't exist at all)
Even now, it doesn't work at my end, other onion websites have no issues.

Have you changed any settings in your Tor Browser/Tor or it fixed itself?

These so called ALM method implementations are trying so hard to remove the main goal of Satoshi. I bet Satoshi Nakamoto knew that if he remained active, he would be put behind bars by the so called lawmakers they feel loss of their control.

But how could we know if it's accurate or just an assumption? Would they be willing to show how they rate these scores on what data or accusations?

Is this a direct advertisement on their banner or just supplied by Google AdSense or any other ad platform with which they're partnered?

I guess that they could collate all of the transactions that are input by users. So, every time someone searches and uses their personal addresses there, they're automatically analyzing if it's from a risky source.

Which could be used against to anyone if ever they've tracked the actual source and receiver and also can be sent to exchanges too if they try to sell the data.

They will just give generic/vague suggestion, such as don't interact with non-compliant platform or don't take any involvement any illegal activity.


We will never know. It'll take serious legal action to find out some details or how well it actually works. For example, legal action uncovered that Chainalysis rely on customer feedback rather than scientific evidence to evaluate it's accuracy[1].

[1] https://bitcoinmagazine.com/technical/chainalysis-investigations-lead-is-unaware-of-scientific-evidence (https://bitcoinmagazine.com/technical/chainalysis-investigations-lead-is-unaware-of-scientific-evidence)

I did exactly is set up a bridge connection or if you already have it you change it to without. and then kept clicking 'New Circuit for Site' until load, and kept the security level at standard.

those steps worked for me.

In general, all AML scores are guesswork. There is no one definitive scoring provider, kind of like how we don't actually have a single authoritative source for the BTC price. (You could say Coinbase, but there is also Binance, Kucoin, Bybit, Crypto.com, OKX ... )

You’re not wrong to feel that way. The push and pull between privacy and regulation is a big part of the story of crypto, and it’s probably not going away any time soon.

Silently implemented, without user consent... All while claiming it is meant to "educate users". DISGUSTING. :-X >:(

I see dangers here: Does this not potentially expose sensitive on‑chain patterns which can lead to doxxing users location and activity?

But I am hoping the risk score analysis system is nothing more than some sort of arbitrary gimmick meant to be a sales tool for compliance services. At least that is what it looks like to me.

You know what would be a good idea? To develop a browser extension that flags websites that add some scummy, devious, user data exploitation nonsense meant for reducing the privacy of everyone else for self-profit.

Seeing this it shows that their analysis is not accurate.

https://www.talkimg.com/images/2025/07/07/UwJjoC.png

So its crazy that they add this up while they are not really sure about the data they release and they still let people to assess the information they read. But hopefully they made a great changes and use reliable outlets to determine that their AML scores provided is accurate so that it will not cause trouble to some entities or personalities in future.

Doesn't work at my end.
It's highly unlikely that this was the solution since it's mostly for those websites/locales where Tor is blocked.

This may be the solution, it seems like that their onion website might be requiring specific set of relay(s) for it to be found. Seems sketchy.
And too troublesome just to use a blockexplorer with that extra feature.

Thanks, BTW.

I don't need such service because I know that I'm doing everything 100% legal and none of my income comes from illegal activities, nor I send any money there. By the way, I'd use it for fun. Since it's free, they are paying the money, so let's let them pay more for this stupidity because they deserve this, this is a total nonsense, stupid idea to normalize AML scoring of every transaction.

To sum up, If people use a VPN and put randomly chosen transactions into that Blockchair's AML analyzer, then I don't see any problem. Not only will they pay for it, they'll collect a false information and false assumptions.

It's strange to see they posted onion link on their clearnet website, but it's not working for some reason.
Maybe this was intentionally disabled to make spying on users more easy.

All of this tools work in similar way and they can never provide precise information.
It's more concerning for me that so many people actually trust this silly aml risk scores  ::)

And there is also government on top of everything.  :P

can't say for mixers, but i tried with an address that received payments from gambling sites, and the results were conflicting as you can see.

https://www.talkimg.com/images/2025/07/21/UAhLFI.png https://www.talkimg.com/images/2025/07/21/UAhcod.png

eeny meeny miny moe, is the address risky or no? you don't know? just generate a random score for the answer.
that's the "algorithm" they use, it's all bs.

aMl rIsK ToOlS aRe FoR YoUr cOiNs sUcCeRtY, ThInK Of yOuR CoInS SuCcErTy.

Yeah I know they are giving different score results, but is probably because they are using different partners and services for this.
And this is my point exactly, every service can have their own last of blacklisted addresses, but none of them revealed that list in public.
They also didn't release their tool as open source, so anything can happen when you type addresses and they are surely getting connected with IP address, browser, OS you used, etc.

I won't ignore the fact that block explorers are a facilitator and have played an important part in Bitcoin's history, and are widely recognized for their utility among crypto users.

However, we don't know if the server is correlating our addresses to our IP addresses, so since 2020, I've avoided using block explorers. I even created my own block explorer using btc-rpc-explorer (https://github.com/janoside/btc-rpc-explorer). I was able to perform queries both on my local network and remotely. However, the electrs server that btc-rpc-explorer used to perform queries stopped working, and I was running out of SSD space due to the electrs server's data indexing. Unfortunately, I had to remove it. Today, I check my addresses through mempool.space on the Tor network (onion address).

I noticed that the blockchain was providing AML scores for each address with a balance, but I don't believe these analyses with 100% certainty. It could just be clickbait to get users to click and pay for their AML score and risk analysis services.

However, if the AML risk score for some of your coins are high, does this imply that they have lower value because they will not be accepted by much of the exchanges? Will this also create another market for high risk bitcoins where the price will be a certain percentage lower? This will be headshaking, I reckon.

In any case, it appears that the Bank of International Settlements has also thought of this hehehhe and for the safety and security of consumers the people from traditional finance who back politicians will lobby for this to become a rule and a regulation.



Crypto exchanges should block users from cashing out tokens with low ‘compliance scores,’ BIS researchers say

In a paper published Wednesday, BIS researchers proposed scoring individuals’ crypto holdings based on their transfer history. The BIS is the Switzerland-based global forum of central banks, and it has often looked askance at crypto, warning it could undermine financial stability and regulators’ attempts to police financial markets.

Read in full https://www.dlnews.com/articles/regulation/bis-researchers-propose-aml-compliance-scores-for-crypto/

It couldn't be accurate, neither even can be called assumption. The kind word is it's a guess work so we don't call it a big clear lie. Blockchain analysis company take hours to days to trace a single address, while blockchair do it in just few seconds the time of downloading the page content. However, it won't be surprise to find that blockchair tie every address to the IP address of the request searching for it to fill its data base with more content. Stay away from this explorer, i stopped using it long time ago after they change the design and replace it with memepool.space a better friendly-use alternative.

@coupable. Agreed. Also, having these types of analysis will bring how we see bitcoin under the control of centralized blockchain analysis firms where their if there is centralization, there is a chance of corruption and manipulation.

An example of this would be if a certain wallet was declared holding bitcoins that came from the darknet by an blockchain analysis firm and this analysis was this paid for by people who want to buy bitcoin atma cheaper price. This is only a quick example, however, we can agree that there are manipulations that can occur.

Ideally, you'd have your own block explorer, such as installing your own BTC-RPC-Explorer or Mempool.space. However, if you want to do it more easily, Sparrow Wallet has a built-in block explorer. If you connect the wallet to your Bitcoin Core node, you essentially have your own block explorer.

https://sparrowwallet.com/features/

I believe that if you connect your Sparrow Wallet to third-party servers, the third-party server doesn't have access to the queries the user makes when viewing transactions in the built-in block explorer.

For those who can't yet have their own block explorer, always use the Tor browser to query your addresses or TXIDs.

This is not directly connected with Blockchair explorer, but you can see direction things are going.
BIS aka Bank for International Settlements proposes grading wallets for permissionless blockchain AML!
This is another attack on privacy and we are going to see this spreading everywhere from banksters.

I cannnot ignore thinking about such scenarios knowing that this service is acting as a blockchain radar without any mention about the method they use or the purpose of such a feature. Logically, this should be an alarming red flag that can destroy the platform reputation but unfortunetly, most of users don't even get interested with that feature expecting it to be another informative tab without thinking what it may running behind scenes.

This brought to my mind the idea the question about those live blockchain explorers. Do they have an activity licence from any legal authority? Or did it exist auditing third oarts to rate those services? This doesn't only apply to bitcoin blockchain explorers but also for others. You can easily note how etherscan is acting like an official ethereum service while it's not maily related to Vitalik company.

I have been using Blockchair for a long time now, but not for what you mentioned here. I still use them to check the transactions, even though I use mempool for the same reason. I think Blockchair is the most popular blockchain explorer because it has the most available chains, and you can just paste the tx to check the transactions.

Do you think we are risking anything just by using the explorer for transactions? I don't use tools from Blockchair, so I assume I am fine so far. But if Blockchair somehow steals data, I think it's time to avoid it. But I am curious if they also collect data from users using the explorer and not any tools.
