Ever since the interview with Lukas Seyfrid (CZ), the chief of the hardware team, it was clear that Braiins is pivoting from the development of mining software, to building their own hardware.

!

This, I believe, is the first iteration of their effort in form of a consumer product, and while it is unlikely to make you a financial return on the investment, it's small form factor and nice anodized aluminum case can allow pretty much anyone to become familiar with the process of bitcoin mining. Or terrorize the testnet. The choice is yours.

I think I might buy one, just to try the viability of a pure solar setup.

HW specifications:

||| | ------------- | ------------- | | Price (pre-order) | $199.00 | | Hashrate | ~1Th/s | | Power Consumption | 40W - 55W | | Number of hashboards | 1 | | Number of ASIC chips | 4 | | Cooling Type | Active | | Noise | 40 dB | | Air outlet temperature | 40-50 °C |

But really, how much would it make in a year?

If we assume the current price and difficulty stays the same, the block subsidy is 3.125 BTC, median fees around 0.2212 BTC, free electricity, you'd get 0.001 BTC per 12 months, which is roughly 65 USD. A little more than 3 years to break even.

It's not going to break any records, but I'm still excited for what's to come next.

It's a successor to the model T, with the new design inspired by the Safe 3, announced earlier this year.

They promise nice, easy to use UI, color display, haptic feedback, gorilla glass. Several color variations are available, including the bitcoin-only orange option.

Globally, people are losing faith in our institutions. Our financial institutions, our governments, our media, our medical systems, even democracy as a concept in many cases. And for sound reasons. Proposed upgrades to Bitcoin's protocol would enable use of the chain (and L2s) for things aside from just money. On the world's most secure document: the bitcoin ledger. It will change everything and here's why.

The root problem is that we are building systems which rely on trust and time and time again, that trust has been broken. We have to trust that the people elected or appointed to those positions will do their jobs faithfully. But, of course, like us, they are humans and fallible. Subject to stupidity, greed, misdirection, and error whether through malice or accident. Take money, for example. Money has to be trust-able, so it is entrusted, for all its faults, to the most stable and neutral institutions humanity has ever created: the state. And yet, the state often abuses that authority to print money they shouldn't leading to inflation and hyperinflation, particularly for unpopular wars of conquest. Every failed state ends in hyperinflation, because it's a tool in the state's toolbox and they will use it when they have no other options. They'll turn on that money printer if they need to. And time after time, they have. There are ways to create trustless systems, where we do not have to trust individual actors to administer them faithfully, only for them to be mostly rational actors subject to the same laws of math and physics as the rest of us. Instead, the system administers itself according to some form of protocol. Bitcoin did this for money 15 years ago, it was created by Satoshi in the wake of the nearly total collapse of the global financial system (2008 financial crisis) to create a system which could not suffer the same fate. We all had to bail the banks out because they were "too big to fail", which was true, Bernanke won a nobel prize in economics for his analysis of this and the bailouts likely prevented the worst economic period since the great depression had the entire banking system be allowed to fail. You may not know who Bernenke is, but if you were alive during this time period, you know his face, he was the guy who had to sell the bailouts to the world as an idea. The reality is, fractional reserve banking is a ponzi scheme, and had the banks failed and people realized it, it would have stopped functioning. Our debt-based world order would have collapsed. No credit could be issued to build roads or fund schools or do anything because there would be no money in the banks to use as collateral and nobody would trust it. Just like in the US great depression. You can argue it's a sneakily beautiful ponzi scheme which drives the engine of human progress if you are a die-hard capitalist, but you can't argue it's not a ponzi scheme.

The crazy thing is, Bitcoin worked. It has kept every promise it made. For 15 years, it has faithfully administered a financial system with a known, transparent, limited supply of 21 million coins which can be transferred across the globe in seconds for pennies in fees. And it has continued to grow no matter which metric you measure it by. Through pandemics, wars, international conflict, attempted bans by major world powers, tick tock, next block, the blockchain continued to function. Not a single hour of downtime, not a single bank holiday, not a single hack or breach of security or protocol. Now, it has a market cap of over 1 trillion USD, which is bigger than the GDP of Israel, the Netherlands, Turkey, or Switzerland, countries with tens of millions of people. It's been consistently over 800 billion for a while now. It moves hundreds of millions of dollars of value on the regular. I can send a transaction to anybody on the planet with a cell phone and halfway reliable internet for under a cent in under a second.

Nobody can make Bitcoin print money it's not supposed to print. Nobody can transfer money without the private key of that coin. Nobody can force the network to do anything outside of its protocol, even if they bought every Bitcoin in existence. Even if they had a trillion dollars and 1,000 people with AKs ready to die for it. It's mathematically, computationally, financially, and logistically infeasible. I think the question is, long-term, how can be we build political and social systems which are equally trustless where we don't have to put people in positions of power. Just like democracy did to monarchy in spreading power around and reducing the damage one corrupted individual could do, we can now do that again in an order of magnitude greater in the same direction towards greater democratization. Whether you're a capitalist, a communist, or a member of the federation of planets, this tech has serious promise for making your ideal global vision come true. It's a matter of setting up the system correctly and getting adoption of it. It can be used for voting systems, for the collection of taxes, for the administration of public funds, goods, and markets. It can be used for a lot more than just money. With smart contract functionality, Bitcoin will be the ledger upon which all this is built.

I'm excited to be here with all of you. We are early. Most people I know don't own any crypto. The future is coming. Thank you Satoshi for your gift to the world.

I've been using lightning for a couple months now and I've read lots of incorrect or outdated information about it online. It's been a very smooth experience for me, and I want to share what I've learned.

TLDR: Using lightning with a custodial wallet (strike, cash app, etc) is as easy as using venmo. Transactions happen instantly and cost pennies, often under a single cent. Using it with a non-custodial wallet is slightly more complicated but well within the ability of the average person as nearly all the complexity has been abstracted away. Lightning scales really well.

Background:

Lightning is a scaling layer for Bitcoin that enables you to make transactions off-chain with security being provided by the base chain. Transactions confirm in under a second and the fees measure in pennies.

A fundamental problem with blockchain is that space in the blockchain is limited. If you increase the block size (number of transactions per block) or add smart contracts, the size of the chain increases. This means you need more powerful hardware and network connection to run a full node, which increases centralization. Bitcoin, at every turn, has chosen to pursue decentralization, but at the expense of higher chain fees since the limited space increases the competition for the available slots. This is why you can run a Bitcoin node on a 10 year old laptop with a 500GB hard drive but you can't run a node for other cryptos unless you have a server and a fiber connection.

Lightning was designed to enable fast off-chain transactions with much lower fees, and it does that.

How to use:

To use lightning, you need a wallet which supports it. You can use a custodial or non-custodial wallet.

Custodial wallets mean somebody else holds the keys/funds and you trust them to hold onto them. "Not your keys, not your coins" as they say. Custodial wallets are also a popular choice for buying/selling BTC since they can often connect to your bank account. Popular custodial wallets for Bitcoin lightning are Strike, Cash App, and Wallet of Satoshi. I highly suggest strike. Using a custodial wallet with lightning is as easy as using Venmo.

Non-custodial wallets mean you hold the key. If you don't write down the seed phrase it gives you and the device with your wallet dies, you will lose your key and your funds. Popular non-custodial wallets for lightning are Phoenix (mobile) and Electrum (desktop). Zeus (mobile) is great if you want more control and the ability to receive transactions while the app is closed. Non-custodial wallets can also be slightly more complex to use. I highly suggest Phoenix, I have been using it and it is awesome. Electrum is great as well, but I haven't used it for lightning.

Note: an on-chain tx is required to move any of your existing Bitcoin into lightning. Unless you bought your BTC and store it in a custodial wallet or exchange that supports lightning.

Myths:

"Lightning requires you to be constantly re-balancing channels"

• If you use a custodial wallet, you don't even have to know what a channel is, your wallet provider handles all of this. For non-custodial wallets like Phoenix, this is mostly abstracted.
• For non-custodial wallets like Phoenix, most of this is abstracted away for you.
  • If you receive a payment and don't have enough liquidity, an on-chain tx will be made which incurs an on-chain fee. Some wallets like Phoenix allow you to rent liquidity for very cheap to avoid these fees.
  • Most people receive their paycheck and then spend most of it, if you follow this pattern, your channels will stay "balanced".
  • Some background on channels: in lightning, you make a "channel" by locking up some BTC. If you lock up 1BTC in a channel, you can send up to 1BTC to anybody else. You can have basically an infinite number of transactions in a channel. Every time you send or receive BTC in a lightning channel, the "balance" of the channel is updated ie how much of the BTC in the channel belongs to you vs the other person you opened it with. When you send BTC, you open up "channel capacity" called "inbound liquidity" for somebody to send you BTC over lightning. If you don't have incoming channel capacity and somebody wants to send you BTC, you will need to do an on-chain tx to create it. It works this way to ensure security.

"Funds are easy to steal on lightning and you have to monitor everything"

• Attacks in the wild are incredibly rare because every incentive is aligned against the attacker.
• If you use a custodial wallet, you don't have to monitor anything and your funds are safe if you trust your custodian.
• If you use a non-custodial wallet, you don't have to worry about this either. Phoenix, for example, automatically uses their watchtower service. As long as your device can connect to the internet every few days, you are fine here.
• The main attack watchtowers prevent against (and really the only attack possible in lightning) is for somebody to "force close" your channel and broadcast an "old" channel state on main chain which assigns the wrong amount of BTC to you. If you watch main chain, you can dispute this state they published, get the correct amount of BTC assigned to you, plus a penalty which is charged to the attacker.
• Lightning is great for everyday spending. If you have significant funds, on-chain txes and cold storage/multi-sig are best.

"You have to make a channel for everybody you transact with"

False. Once you have a channel with anybody you can use that channel to route payments to anybody else on lightning.

"You have to keep manual backups of your channel state or you can lose your funds!"

This is true, but this is usually automated and built into the app. With Phoenix, for example, so long as you have your seed phrase you can install Phoenix on a new phone and automatically retrieve the backups made of your chain state since Phoenix's developers automatically keeps the backups. Other wallets offer similar "storage via lightning" backup options.

With custodial wallets, they do this automatically so you just have to remember your username/password.

"Lightning doesn't scale"

• Lightning scales very well. Once you create a channel, you can have essentially an infinite amount of transactions in it, all of which occur off-chain. There is enough chain space to make lightning channels for billions of people.
• This provides enough capacity for significant growth in Bitcoin's adoption
• A single on-chain tx can make a single channel. There are proposals in the works to make multiple channels with a single tx (channel factories) and other L2s like Ark and Fedimint which extend/complement lightning.

"Sure fees are low now, but as more people use it, fees will get high!"

No. The reason fees increase on main chain is because you have limited space and you must pay miners for that space. A lightning channel, once opened with a single on-chain tx, can host millions or billions of transactions. The cost to route these transactions is extremely small from a computation standpoint, there is no mining required. Space is not limited, so competition for space doesn't drive high fees.

"Lightning is centralized"

Wrong.

• Lightning uses the security of Bitcoin's L1 to secure transactions.
• Transactions are routed through a network of lightning routing nodes, there's currently at least 41,000 of them, you can run one on a Raspberry Pi.
• Routing nodes can't rug you or steal your funds. You don't have to trust those nodes to secure your BTC, that is secured by L1.

Hello everyone!

I made a site where you can make bets online with an electrum multisig wallet (p2wsh). I made the UX easy as possible for onboarding and I'd like to hear your feedback about it. The website is currently live on BTC testnet3. I made a cheesy tutorial as well!

The site is: https://olivetitan.com

You can get testnet coins from https://cryptopump.info, https://bitcoinfaucet.uo1.net/ and many others.

I think this is the safest way to bet online currently. BTW you get proof, that you lost :)

No one can cheat.

I'm also looking into bitVM and exploring how that can help. Still learning!

Thank you for reading and hope you have a great time! ♥

NOTE: Do not use LTC, it asks for real LTC, not testnet

"Prosecutors are alleging Samourai Wallet laundered over $100 million in criminal proceeds."

"Recent regulatory action against Consensys and Samourai has instilled fear among other crypto service providers operating in the United States."

• Wasabi is the main competitor to Samourai's whirpool mixing service. The only one flying under the radar currently is Joinmarket.
• Phoenix is the Lightning network wallet where users keep custody of their funds, but the channel management is outsourced to the company. The only remaining self custodial lightning wallet that remains is Breez.

While this news is deeply troubling, it might push further development to more sustainable trustless self-custodial solutions in the long term.

Luke-jr has always seen Ordinals as a threat to #Bitcoin. He intends to offer a solution that will prevent the creation of new ordinals.

Hi all! Does anybody know if bitcoin core (bitcoin-qt) is also vulnerable to keybleed / randstorm? Thank you

A new type of vulnerability has been found, affecting the routing nodes, allowing the attacker to steal the amount locked in HTLC you're forwarding for them. Several scenarios and possible mitigations are suggested in the article.

For more details, see the original paper: https://github.com/ariard/mempool-research/blob/2023-10-replacement-paper/replacement-cycling.pdf

Discussion on stacker.news: https://stacker.news/items/288995

There's a new Trezor HW wallet available. It's a long awaited refresh of the original Trezor One. Two buttons, one screen, USB-C, and a new chip that makes it tick. Now with 100% more secure element!

They also offer a new cold storage solution - https://trezor.io/trezor-keep-metal . The form factor is similar to cryptosteel, but the mechanism of entering the seed phrase is different. You punch a bunch of holes in the metal plates. Depending on what material is used, I'd say it's much more fool proof compared to cryptosteel. If an unsuspecting nocoiner opens it, there is no risk of them just spilling all the letters out and financially ruining the whole family in the process.

I'm sick of coming here and not having somewhere to talk so here's a thread for everyone.

I like Bitcoin, and u?

He has invested many years ago, he doesn't remember how much and he has never been able to figure it out himself so now im trying to help him on the first page it says "bitcoin" his mail and then some letters and numbers in a string, and then some random notes and a few shopping lists, but on many pages is the exact same shopping list consisting of 7 items so i think that might be the code but idk i have not yet found anthing that could be the code can anyone help me getting his bitcoins back

Not sure how serious, anyone know more?

Is there any online service/tool/website which provides a way to show badges (little SVG images like are commonly seen in Github readmes) which show the balance of a BTC address? Bonus if it shows the USD value as well. I found a project on github called balancebadge but seems to be dead.

This is so we can show the current total amount of donations made to an open-source project.

Example of badges I’m talking about:

TL;DR- Be optimistic, but not fatalistic. Success still requires action. The article is worth reading in full, though.

This attitude entirely ignores and greatly increases another exploitable attack vector: stalling and preventing beneficial changes to the protocol which can enable more robust peer-to-peer and self-custodial solutions on subsequent layers. Indeed, after the spectacular failure of SegWit2x, any adversary would likely conclude the stalling strategy to be far more viable. > >

That'd make them the largest company to do so, as far as I'm aware.

Title mostly says it all. I have a hardware wallet but the battery is toast and it only works when plugged in, and the buttons are a little sketchy at times, sometimes they work sometimes they don't.
