Blockchain Analytics is More of an Art Than Science

[cryptosize]

Don't you think the conversation has gone out of the general board's theme? I suggest we keep talking about the analytics and avoid posts regarding society in general.

If you didn't know it, Monero full nodes need to keep all the outputs and be able to efficiently index them, whereas in Bitcoin, you only need to keep UTXOs.

No I didn't, thanks for clarifying that. I don't think satoshi wanted to create a fully anonymous chain, even though your posts are accurate and he seems to be in favor of total anonymity.

But HmmMAA insists Bitcoin was created to take away anonymity.

I think we are right on topic, the exact part that matters the most, anything that doesn't affect society at all might as well be ignored and not discussed, blockchain analytics are fine if people want to use them for educational purposes, fun or whatever other purpose they see fit, it's completely fine if someone wants to randomly point to a bitcoin address and say this is owned by that person, nobody would care about it -- but when such guessing becomes a tool in court on its own then that is a catastrophe that will affect people's lives directly.

If you think about it, nothing is really anonymous on the web.

As o_e_l_e_o said above, monero has a bounty of $625,000 if it gets cracked. If it gets hacked indeed, can you imagine how bad it will be for its reputation? Essentially the chain will be worthless.

So, creating a fully anonymous blockchain is also risky for this reason. Imagine Bitcoin, claiming to be anonymous, but getting hacked.

Satoshi didn't want to take away anonymity. He seemed to love anonymity. I suspect he was unable to fully guarrantee anonimity and therefore, he chose pseudonimity. Personal opinion, of course.

So, who the hell tells you that policemen cannot receive magician training to plant you some kind of pill/drug in your car?

It is of course trivially easy to plant something with or without bodycams. And even if it were impossible, police could simply charge you for running a stop sign, running a red light, using your phone while driving, dangerous driving, or a hundred other things where bodycams are useless. More surveillance is never the answer, which is why even the NSA have admitted that mass surveillance has never prevented a single terrorist attack.

As o_e_l_e_o said above, monero has a bounty of $625,000 if it gets cracked.

Note the bounty no longer exists.

The bounty eventually evolved to cover either Monero or Lightning transactions. It was awarded to Chainalysis in September of 2021, just before they publicly announced their "transaction monitoring solution" for Lightning (https://www.chainalysis.com/blog/lightning-network-support/).

So in other words the Monero bounty was unclaimed, and Chainalysis were awarded the money for instead offering the US government Lightning monitoring services.

It has been broken in the past:  https://www.schneier.com/blog/archives/2018/03/breaking_the_an.html.  There have been hard forks since then that enhance privacy further.  Its reputation is fine.

It's the perfect topic to comment out that part.

Monero is the best cryptocurrency in terms of anonymity, and second-best in terms of research, as per my experience goes. If Chainalysis could break it, I'm pretty confident they could tell the difference between a segwit and non-segwit address or the difference between bits and bytes.  

I can imagine how inaccurate their lightning network monitoring reports will be.  

[o_e_l_e_o]

I can imagine how inaccurate their lightning network monitoring reports will be.

Oh, absolutely. As we have seen in this thread, they fail to understand the most basic concepts about bitcoin (such as segwit v non-segwit), or indeed the most basic concepts about computers in general (such as bits v bytes). They fail to understand how easily their simply heuristics are fooled, such as with change being sent to different script types. They have absolutely zero evidence that their on-chain analysis is anything other than complete guesswork, and cannot say how many false positives they identify with their random guesswork. I am certain their Lightning analysis will be similar flawed, at best.

However, apparently none of that stops the government relying on this made up bullshit in court and using it as evidence to prosecute potentially innocent individuals. If Chainalysis are offering it, the government will be buying it and using it against anyone they like.

How do they analyze Lightning?

There is no ledger/blockchain to begin with...

ps1: Monero has not been broken (highly unlikely IMHO), but they will delist it from various CEX (which proves it's an actual danger, since the bounty hasn't been claimed so far). It's still listed in Binance, Kraken, KuCoin to name a few.

ps2: KYC is debateable and highly overrated.

Let's say that I buy 1 BTC from Binance (with my own identity) and I gift it/sell it to someone else (either hand the private key or send it to another address).

Chain analysis companies will still claim it's my own property, even though it no longer is.

Don't sweat it too much, as long as it's stored in your own personal wallet and not on a CEX (even if it's the "trustworthy" BlackRock with their ESG shenanigans -> could easily steal your BTC IOU if you don't comply to climate change demands for example).

Oh, absolutely.

funny. you two always make me laugh at your ignorance
look at the DCG portfolio.. notice the main LN devs are in the same portfolio as chainanalysis. notice all the other portflios of services that share information

it only takes a few nodes in certain network positions to intercept paths of data. especially now those teams in DCG portfolio are also offering monitoring LN software
when "greenlight" manages the channels and payments. guess where that data goes

[BlackHatCoiner]

How do they analyze Lightning?

The only way is to run several lightning nodes with large liquidity, trying to make a conclusion out of the routed transactions. For instance, if I only own a channel, which to my unawareness is owned by Chainalysis, and I want to send a payment to a lightning node which also shares channels only with Chainalysis nodes, then Chainalysis can de-anonymize the payment.

Chainalysis will quickly notice that it isn't practical to own half the network, so we should expect the same guesswork with now, squared...

[franky1]

LN has a flaw of only 20 hop distance.. so they create "trampolines" where you send a message to a service that is distanced somewhere else on the network where they create the onion to the destination on your behalf.. meaning you tell them teh amount and destination you want..

LN has a flaw of only channel imblance and bottlenecks.. so they create "hubs" where you let them have your value, let them set up a channel and you just have some msat balalnce where you tell their software what destination you want and they read the gossit to create the path

LN has flaw of complicated integration of LN node and bitcoin node and scripts inbetween.. so they create "greenlight" that manages the node and communication process and onion routing paths and you just do the signing of value to the channel partner

[i can go on, and on]

and yet people think that LN is a decentralised system of user full control of funds..

when you look at all the big services that are all sister companies of DCG or other institutions that have to follow MSB regulations. it should awaken you to how many nodes are sharing data to chainanalysis

It's always the "money" that creates problems and fixes them, these companies have the motive and the means to convenience or even force it on the government to buy and use their terrible tools, on the other hand, going against that doesn't earn you any money, who would spend millions of dollars to convince the government that this Chainalysis is nothing but horseshit? the a few people who have the perfect understanding of how the system works have no means of imposing their opinion.

We still have fools in our government who are highly influenced/controlled by the banking mafia who claim that Bitcoin was created by some sort of origination with the intent to collect as much money as they can before changing the password and deleting the Bitcoin website  , no matter how hard we try to explain the truth to them -- our voices are hardly heard because we don't have the tools our enemy has.
