  • Generally, votes are overrated. Especially if you’re not mainstream, by definition most people won’t support you, won’t agree with you, won’t understand you.

    Some things may be downvoted because they’re too stupid. But occasionally, you might be downvoted simply because you’re a bit too early. Like, if you’d said “being gay is not crime” or something 50 years ago, you might have got downvoted… Just a thought.

    A fun project would be: factor Mersenne numbers! Naive trial division -> optimize your code by only trying valid candidates (you’ll learn about quadratic residues, Jacobi symbol etc.) -> You’ll soon realize that trial division only goes so far, motivated to learn new approaches. The P−1 method may impress you, it’s powerful. Enjoy coding that. -> But then, you’ll be frustrated by even stronger opponents here and there beyond M100, which the P−1 method can’t factor. Now you’ll be so ready, even determined, to learn ECM. At this point, you’ll find using elliptic curves is actually not so difficult, because it’s just like P−1. And yay, 20- or 30- digit numbers are no longer your enemies, they’re just small fish, elliptic curves rule!

    Before you know it, you’ll have a clear, intuitive vision about “an elliptic curve over a finite field”. Try to understand why ECM works. Try to count the number of points. Everything you experience with ECM is related to ECC too.

    I’m not that good; know enough to know that I don’t really know much. Just a hobbyist; posted ℍappy ℍamilton Day! here.

    Thanks for joining monero.town :) Not only it’s a good crypto—it is a great privacy tool, recommended e.g. by privacyguides.org, accepted (as donations) by the Tor Project (which is endorsed by the BBC, the New York Times, etc. and now also by Amnesty International), by Tails.net, and many other privacy advocates.

    You might be thinking about “investment” but the implications of Monero is much, much bigger—among other things, you may question today’s privacy invasion by some oppressive governments or monopolizing companies like Google.

    Gandhi said that whatever you do in life will be insignificant, but it’s very important that you do it, 'cause nobody else will.

    Also, if you happen to be a math geek or a cypherpunk, this thing is based on Elliptic (Ed25519)—something deep and fascinating for number theorists to study!



  • I value the freedom of free software. A fork is good in that context.

    PoS has at least one good aspect: it’s perceived as “green”. Other than that, afaik PoS tends to imply that only a few rich people can determine whether something is okay or not. The Monero network, on the other hand, is carefully designed so that any one with any CPU can participate (at least in principle). This design philosophy feels good.


  • Ah, incoming is now bigger intentionally! Thanks for sharing this :)

    donation-less builds floating around, which I will not link, out of respect for the XMRig dev.

    I wouldn’t recommend a random build “floating around”, not because doing so is disrespectful to the original dev, but because it might be dangerous.

    If a random anonymous person A says, “Use this build B. It’s better!” and a user C does so without suspecting a thing, C is likely to be in big trouble sooner or later: even if A is an ethical hacker and B is a good build, such a mental attitude of C seems dangerous, especially when the tool is crypto-related. Because Person A could trivially share good source code (donation just commented out), but compiled different (evil) source code and share them with the said good code 😓
    If 1% is big for you, or you have privacy concerns about remote connections for donation, well, you might want to think about something obvious: blocking remote connections is easy when xmrig just needs to talk to 127.0.0.1.





    • Tuta (free): you can send only like 6 email per day. Otherwise, Tor-friendly. No onion. Support forum on Reddit 😞 Germany.
    • Posteo.de: 1 €/mo affordable. Nothing fancy. Support via PGP like that’s common sense. Germany. Non-crypto anonymous payments w/ various options (e.g. a prepaid CC): they don’t even ask your name (much less address, cell phone number).
    • Disroot.org: Free, pop/smtp, community-based, trusted even by the Tails team. w/ onion. Netherlands.
    • Cock.li: Free, pop/smtp etc. Very Tor-friendly w/ fast onion. It’s good if you think it like disposal. Irresponsible in a way (aka Freedom), but actually 10-year-old & stable. Romania.
    • Proton (free): bloated, very mixed opinions, yet better than Google. w/ onion (slow). Switzerland. A simple feature like Plain Text view is missing (HTML by default: not serious about privacy).

  • –out-peers 64 --in-peers 32

    Note: For some reason, starting from v3.7, p2pool docs say --out-peers 32 --in-peers 64 (in is bigger); probably just typos. The doc also says: “If your network connection’s upload bandwidth is less than 10 Mbit,” use 16 & 8 instead.


    For the sake of fairness and transparency: 1% of your hashrate will be “donated” if you use an official Xmrig binary file. However, it is free software and you’re free to study how the program works, and change it anyway as you wish, if you’d like to.


    Your P2Pool wallet adress is public, periodically move mined funds to a new, truly private XMR wallet

    While doing this periodically is not absolutely necessary, there is some practical consideration: when there are many, many coins in your wallet, it’s technically impossible for you to spend (send) them in one go. If this situation ever happens to you, just send funds little by little (output will be consolidated). Feather Wallet may be convenient, where you can see and control individual coins, just like in Electrum. Happy studying, happy ethical hacking, happy mining, and happy holidays! Have happiness that money can’t buy :)
