  • pulsewidth@lemmy.worldtoTechnology@lemmy.zip•Fear that quantum computing is on the cusp of cracking cryptocurrency's encryption spurs a global investment firm to remove Bitcoin from recommendationsEnglish

    Businesses/orgs that have smart leaders are already implementing (or have already completed implementing) post-quantum encryption algs/methods into their systems to protect them for when quantum computers and quantum programming mature, making their existing encryption defeatable. For most systems it’s just a matter of a software update and re-encrypting any data.

    Eg: https://arstechnica.com/security/2025/10/why-signals-post-quantum-makeover-is-an-amazing-engineering-achievement/

    This is a problem for public proof-of-work systems that cannot change their encryption, eg: all crypto. Bitcoin cannot change how their coins are encrypted without redesigning and completely rebuilding their public blockchain - it would require concensus from all major bitcoin users and businesses (coin exchanges etc), and could potentially leave any prior-minted bitcoin vulnerable anyway. It will not happen anytime soon - and when it does happen, it may be too late.

    Hence, its actually pretty high on the list of quantum targets, and will likely be attacked as soon as it’s available. Some people might be able to steal a bunch of Bitcoin and exchange it for other new (secure) coins or for cash, and get out before the Bitcoin public realize its been cracked. At which time the Bitcoin price will crash hard and may not recover (depending on what action they take to resolve the issue), so the cautious are getting out asap.

    Another perspective:

    1. You can own your own music in many more formats than just vinyl.
    2. CDs are still being made, and cheap. Second hand CD trade is huge, and they are always cheaper than vinyl to buy and ship. Digital ownership is even cheaper (eg Bandcamp), and the same or higher quality.
    3. RuTracker has an enormous collection of FLAC well-seeded, as do other sites (but they require invites). Soulseek has an enormous collection and requires no account.

    Regarding equipment just get some good speakers and an amp, you’ll need that regardless of what format you end up getting your music in.

    Vinyl is often a trap. Expensive, fragile, degrades, difficult to resell unless you live in a big city (postage & packing), and the quality is ultra subjective and varies wildly between pressings. Just look up a couple of popular albums you know on Discogs or rateyourmusic and browse the comments see what they cost and how many people bring up complaints on pressings.

    I’m all CD and FLAC and loving it. Bandcamp is my first port of call, then CD (new or second-hand), torrent if rare or OOP or unavailable anywhere I frequent.

    Something else that may help - if you really think vinyl will sound better, enormous FLAC rips (2GB+) of popular high quality pressings in 192kHz/24-48bit rips are not uncommon on torrent and Slsk - vinyl enthusiasts often make a high quality digital capture of their purchases while the vinyl is new, so that they have a near-new copy in case their vinyl ever degrades with wear - or simply so they can use digital for convenience, but keep the analog hiss and increased frequency range of vinyl pressings. Best of both worlds.
