    Hi /r/Bitcoin!

    My name is Jeremy Rubin and I'm the author of BIP-119 OP_CHECKTEMPLATEVERIFY. Verification on Twitter.

    I figured running an AMA would be a great opportunity to get community feedback on the proposal and answer any questions about CTV or anything else you want to know!

    Some basic background:

    CTV adds a new capability in Bitcoin scripts that allows you to control how coins can move around. Before CTV, once you have the signatures you can spend the coin however you want. After CTV, you can make it such that a coin has to go through a sequence of steps and signatures before it can be spent. This lets you, for example, build time release Bitcoin vaults. There's a ton of other use cases and material available on https://utxos.org to learn more. I personally recommend starting with Aaron van Wirdum's article https://bitcoinmagazine.com/articles/secure-the-bag-cutting-transactions-in-half-to-resolve-bitcoin-network-congestion which explains the basics & how CTV can improve scalability in an approachable way.

    I'll be answering questions real time for 3 hours starting at 9am PT, and will answer any remaining questions throughout the day.

    Ask away!

    p.s. ask the AMA questions here, but be sure to join the TG group for updates & discussion longer term https://t.me/op_ctv_chat

    p.p.s., some people have asked where they might send some coin. I have an address here https://utxos.org/sponsors_addr/ which is signed through utxos.org and keybase (3LPmfWnmQcPK1T9mSVGtoMmcQXbRAuUfus). You can DM me for a non-reused addr or to discuss how funds might be used.

    Doing my bit for adoption

    Posted: 04 Jun 2020 10:22 PM PDT

    Hi guys , my graphic design business and SEO business is now accepting bitcoin as a payment method. I am super excited about supporting bitcoin long term and how it can improves our bottomline.

    Infact , bitcoin payments is a "requested" feature by SEO clients doing casino websites.This proves that adoption is getting there slowly but steadily or so I would think.

    What I Love About Bitcoin...

    Posted: 04 Jun 2020 03:47 PM PDT

    The anticipation I feel when I send my hard earned money to an address just hoping it shows up sometime soon

    And the relief I feel when it arrives

    The anxiety I feel withdrawing from an exchange before it gets hacked

    And the relief I feel when it returns back safely

    Going to bed up hundreds, waking up down hundreds and yes, going to bed down hundreds and waking up down more hundreds

    Hiding my seed somewhere safe and hoping it's still legible if I need it and sharing that location with someone I trust - for now

    Sleeping with my Nano in my pillowcase and waking up with Ledger imprinted on my cheek

    The desire to Hodl versus the desire to take a profit, after all, Hodling is way more important than taking profits

    The thrill of recognizing and warding off endless scam emails and phishing attempts that haven't been able to fool me (yet)

    Suggesting to friends and family they invest in Bitcoin and having them look at me like I'm out of my mind

    Teaching a newbie about Bitcoin and frustrating myself to no end, and not caring that I was once them

    Reading about technical blockchain stuff that is so far over my head I have to have an out of body experience to grasp it

    Perpetually wondering if Bitcoin will go to a million or zero or at least 11K again

    Buying all my Bitcoins at $19,783 and savouring the deal I got

    Dreaming my $10/Bitcoin buy limit order for $10,000 worth may accidentally fill

    Bashing myself for not being an early adopter and missing out on a chance in a lifetime

    These are some of the reasons I LOVE Bitcoin! How about you?

    Introducing the NGRAVE ZERO hardware wallet

    Posted: 05 Jun 2020 04:08 AM PDT

    Introducing the NGRAVE ZERO hardware wallet

    Dear community, I would like to introduce you to our new hardware wallet - NGRAVE ZERO - but first I want to address the likely immediate skepticism popping up in your head - "oh no, another one, why should I even bother listening to this?", etc. You might be thinking something along these lines, and rightfully so if you do. So, I want you to know why we really built this.

    We chose this path because we are blockchain technology believers, yet our very own experiences have reminded us over and over again that holding crypto isn't safe or at least full of dangers. The best (and for him worst) example is our CTO losing 44,000ETH with his company SwarmCity in the 2017 Parity hack. Similar experiences brought us, the three co-founders of NGRAVE, together in 2018. There and then, we decided to build the one solution that we would fully trust with our very first till our very last bitcoin. A solution to empower you, the user, to start truly owning what is yours.

    Throughout our journey, we partnered up with world leading players in nanotechnology, applied cryptography, hardware security, and more. Even the second reference of Satoshi's famed bitcoin paper - the famous cryptographer Jean-Jacques Quisquater - mentioned in almost every cryptography paper - joined in on our project. The result: we built, from the ground up, a new hardware wallet - ZERO - and a new metal backup solution - GRAPHENE. We even designed a system, together with Chainlink, for the safe posthumous recovery of your keys by your family, when the time comes.

    We analysed the end-to-end process of you owning your crypto, starting with the generation of your private keys (or master seed), having a real time overview of your accounts, receiving and signing transactions - basically your full user journey. And we left no stone unturned when looking at your security and ease of use. Today, I'm happy to tell you that our pre-order is live on Indiegogo since one week, and that we just surpassed our 500th backer.

    With leaving no stone unturned, we really mean it. We for example upgraded the key generation process, so that you no longer have to worry about backdoors in the interior (TRNG) chip (not necessarily by the manufacturer but even by governments and intelligence agencies), or that the hardware manufacturer might have information on your keys. Our ZERO is completely offline, multi-layered tamper proof, and the only blockchain solution in the world with an EAL7 security certification, the highest achievable. That's how serious we take your security.

    I'm telling you this now as I believe this is a very good time to contemplate how serious you are about your security and ease of use when managing your crypto. Especially since several of us are already smelling the next bull run. Also especially since you can get the ZERO and GRAPHENE at a considerable discount, right now. And especially since your security is not open for discussion.

    And know, if our intention was purely to sell and get rich, we would have chosen an easier entrepreneurial path, but we didn't. We chose the extremely challenging mix of hardware, high security, crypto (a difficult environment to sell given the unfortunate high amount of scams, as well as we started this journey when crypto winter kicked in). We chose this path because we are all-in into fostering worldwide blockchain adoption, and therefore, we make a promise to tackle the security and usability hurdles. No cutting corners.

    Start truly owning what is yours.

    Ruben

    Bitcoin based debit cards?

    Posted: 05 Jun 2020 01:55 AM PDT

    Got my bank account frozen earlier today due to a Localbitcoins transaction, which really chaps my ass. Sold off some BTC, and apparently the Interac e-Transfer that hit my account was fraudulent.

    So due to the bank's shitty security protocols and them allowing a fraudlent payment to go through, they decided it was a good idea to penalize me and just freeze my money. Then I find myself stuck on the phone for a couple hours, talking to some stranger sitting in a call center on the other side of the country, asking for their permission to access my own money, which I was denied. Sorry, but I shouldn't be penalized because they're security sucks and they dropped the ball.

    This is why I like bitcoin. It's my money, and nobody can touch it except me. I don't have to ask some stranger's permission if I'm allowed to access my own hard earned money. Fucken banks, I'm pissed...

    Anyway, any advice on good Bitcoin based debit cards? I know there's AdvCash and I'll grab a couple of them, but if you know of any other reputable debit card providers out there, I'm all ears. I'm going to distance myself from fiat, as it's total bullshit that people have control over my own money like that.

    If anyone else has had their bank account frozen due to shit like this, feel free to use this thread to vent. I'm pissed... that's my money I worked really hard for, assholes.
