Bitcoin

zkSNACKs, the developer of Wasabi wallet, has shut down its coinjoin coordinator since June. The news is not surprising, considering that it has already been unavailable for the US customers since May.

Since the wallet itself is non-custodial (you hold the keys), and it's using block filters to update your balance directly from the bitcoin network, the wallet functionality is intact. However, if you want to coinjoin, you have to find another public coordinator.

A list of currently active coordinators is available on wabisator.com, or wasabist.io

Coordinators do not require any privileged access to private information, so it should be safe to use any 3rd party coordinator with enough real active users. At no point are your funds at risk of being stolen.

However, a dedicated attacker running a public coordinator could still pull a de-anonymization attack by mixing your coins solely with their own outputs.

A great way to help humans in need, and a great example of a use case for bitcoin.

WikiLeaks co-founder Julian Assange is free after a 14-year battle against extradition to the United States. In a final effort to secure his freedom, an anonymous Bitcoiner donated over 8 Bitcoin, worth around $500,000, to help Assange’s family pay off the debt incurred by his travel and settlement expenses. [...] The donation link was posted by Stella Assange on June 25, and within 10 hours, an anonymous Bitcoiner paid over 8 Bitcoin (BTC) to the fund, almost clearing the goal of $520,000. He has also received over 300,000 British pounds ($380,000) in fiat donations so far.

The single Bitcoin donation was the largest donation to the fund, more than all other donations in all currencies combined. As a result, Assange will arrive in Australia debt free.

Had dinner with some boomer-age family friends tonight who shared stories about their grandparents and other relatives who survived (or didn’t survive) the holocaust.

One family, posing as Christians, managed to escape Poland to the US in 1939. They had to travel through Nazi Germany and Italy on their journey.

This family invested much of their life savings into expensive camera equipment to not raise suspicion, as they were traveling under the pretense of going on holiday.

The conversation developed into all the ways people attempted to conceal and travel with wealth as they fled their homeland. Apparently, sewing diamonds into clothing was a common tactic.

These close friends were struck to hear how Bitcoin enables the storage and transfer of wealth by simply knowing a secret number. I told them of the work @gladstein and others are doing to get Bitcoin knowledge and tools into the hands of political activists and refugees.

“Fuck You Money” is a world changing technology. Let us not lose site of what really matters here 🫡 🤙

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:

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.

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.
