eXaMineR: free and open source monero tracing tool
Переглядів 5502 місяці тому
I recently explored the tracability of monero and found this gem from Ciphertrace: news.bitcoin.com/ciphertrace-enhanced-monero-tracing-capabilities-governments/ It's a really neat visualizer of the monero blockchain with a way to trace it. And I wanted ot make something similar. So I did! Please help me improve it and make it better by contributing to my github: github.com/supertestnet/examine...

    1. this is nothing new, poisoned outputs have been known about since day 1 and mitigations well understood. 2. this is useless if no KYC is involved, which is becoming evermore commonplace as XMR keeps being delisted and trading moves to decentralized exchanges like Haveno, Serai, etc. 3. ring signatures are already slated for deprecation in favor of full-chain membership proofs, potentially as early as next year (2025). Bye-bye decoys, hello zero-knowledge proofs. As far as LN goes, I suggest you visit Dread and see for yourself what the darknet's expert consensus on L2 in particular and BTC in general is. Spoiler: it aint good.

      The analysis techniques that he's using reveal (heuristically, not with absolute certainty) parts of the transaction graph. Is the use of shielded addresses sufficient to ensure privacy given that information about the transaction graph? No. For example, Bitcoin wallets typically by default generate a new random address each time you ask for your address, and we don't consider that to be sufficient to make Bitcoin a private cryptocurrency. Zcash also effectively has stealth addresses (that is, notes are encrypted to the public key of the recipient, extremely similar to what Monero does at that layer apart from using ECIES instead of ElGamal in the encryption scheme). As a designer of Zcash (and cryptologist more generally, if that credential matters to you), I don't consider that to be remotely sufficient for privacy. In fact, we don't even advertise it as a privacy feature, because that would be misleading. It helps privacy only in combination with other aspects of the protocol. In Zcash's case, the use of zero knowledge proofs has a similar effect, in Monero terms, as if shielded Zcash transactions had decoy inputs for *every* previous shielded output. While you may be able to eliminate some outputs using similar heuristics to those described in the video, you're starting from a hugely expanded set that never exhibits recency bias, for instance. Monero would need to do something similar in order to defeat the analysis described here.

    • @highlevelbitcoin

      Two reasons: (1) it's annoying to test with multiple files because my browsers cache separate js files, and I have to remember to clear my cache before every test, otherwise my code changes don't take effect (2) shareware is easier to deploy as a single file rather than a folder

    If it fully Turing complete (because of the CPU), then how are you planning to solve the halting problem? Gas metering would be a BTC fork, no?

    • @highlevelbitcoin
      @highlevelbitcoin 4 місяці тому

      it's not "fully turing complete" because there is a limit on how many cpu cycles this cpu can run for. It's a large limit, somewhere on the order of 2^128 cycles, which is far more cycles than any cpu has ever run. But it is technically a limit, so this cpu is not "fully turing complete" and is guaranteed to halt eventually. Just long after the death of the universe.

    • @highlevelbitcoin
      @highlevelbitcoin 4 місяці тому

      Besides every program being guaranteed to halt eventually, another factor is this: the two parties agree on the program up front, and the challenge period limits how long the prover has to run it. So if the prover for some wild reason agrees to run a program that doesn't halt quickly, the verifier can initiate a challenge to prove the end state, and then the prover will simply lose his money when he can't get the program to terminate before the challenge period expires.

Side note: I was also hoping to build a system that tracks the value of BTC nodes using the value of Lost BTC. I think lost BTC gives BTC nodes intrinsic value and they can be traded based on the average value of lost BTC represented by each node.

    OK, so I guess the problem is, you need 3 transactions to open and close a Hedgehog channel, whereas in Lightning you only need 2. Just a question on what you want to tradeoff.

  • @MrCoreyTexas
    @MrCoreyTexas 5 місяців тому

    Just started watching this video, it sounds like it could be a lightning killer at first glance. I think the fact that the recipient has to be online to receive the payments is a huge disadvantage for Lightning. I saw a recent article, we're seeing lightning nodes actually go offline, and they were trying to spin it as positive somehow (seems like a cope).

    As far as I can tell, only 1 person deposited 0.25 BTC into the smart contract to begin with, ideally each one would deposit 0.125 BTC, but then they'd have to use partially signed bitcoin transactions, right? Another thing is teams usually aren't 50/50 to win, there's a favorite and an underdog, so Alice and Bob would have to agree on the odds as well

    • @highlevelbitcoin
      @highlevelbitcoin 5 місяців тому

      If I was building this out in real life I would probably use partially signed bitcoin transactions to ensure both parties deposit funds, though another option would be to use an atomic swap so that Alice pays Bob to put the total into the contract in such a way that he only collects her payment if he does so. Also, yes, the two parties would need to agree on payout terms such that both are happy with whatever the terms are

  • @MrCoreyTexas
    @MrCoreyTexas 5 місяців тому

    At about 46:00, I think you're being unfair to satoshi. Bitcoin core needs to know how long the script is in advance, so it's prefixed by a length of script. Otherwise, you'd have to have some kind of 'end of script' opcode, but let's say that it was 0xFF for argument's sake - but then 0xFF can also be part of a hash or preimage, so that would confuse Bitcoin Core. Perhaps there's a better Javascript bitcoin library out there?
