I've build three physical Bitcoin hubs in my life, (Bitcoin Embassy, BlockHouse and Bitcoin Jungle help) and I've visited countless others.
The new Freedom Center we are building in Bitcoin Jungle will become the most awesome.
Think of it as a private members club with gym/sauna/cold plunge/pool with wellness activities, that's also a coworking space for digital nomads and expats, that has classrooms to teach freedom tech to locals, and dozens of monthly events on a massive rooftop terrasse.
Yes, it's real. Opening today!

The personal, as everyone’s so fucking fond of saying, is political. So if some idiot politician, some power player, tries to execute policies that harm you or those you care about, take it personally.
Get angry.
The Machinery of Justice will not serve you here – it is slow and cold, and it is theirs, hardware and soft. Only the little people suffer at the hands of Justice; the creatures of power slide from under it with a wink and a grin.
If you want justice, you will have to claw it from them.
Make it personal. Do as much damage as you can. Get your message across.
That way, you stand a better chance of being taken seriously next time. Of being considered dangerous.
And make no mistake about this: being taken seriously, being considered dangerous marks the difference - the only difference in their eyes - between players and little people.
Players they will make deals with. Little people they liquidate.
And time and again they cream your liquidation, your displacement, your torture and brutal execution with the ultimate insult that it’s just business, it’s politics, it’s the way of the world, it’s a tough life and that it’s nothing personal.
Well, fuck them. Make it personal.

Bull Bitcoin becomes the first mobile Bitcoin wallet that allows users to send and receive asynchronous Payjoin transactions without needing to run their own server, using BIP77!
I am very excited about this new and bleeding-edge feature, because it has been a long-standing ambition of Bull Bitcoin to become the first Bitcoin exchange to process Bitcoin withdrawals via Payjoin (Pay-to-Endpoint) transactions.
However, it was hard to justify Bull Bitcoin investing time into building this feature since there were no commercially available end-user Bitcoin wallets that were able to receive Payjoin payments.
Indeed, in order to receive Payjoin payments (BIP78), a Bitcoin wallet needed to be connected to a full node server and be online at the moment the payment is made. This means in practice that only merchants, professional service providers and advanced full node users had the capacity to receive Payjoin payments. This is, we believe, one of the major reasons why Payjoin had failed to gain significant traction among Bitcoin users.
For this reason, the Payjoin V2 protocol (BIP77) was conceived and developed by Dan Gould, as part of the Payjoin Dev Kit project, to outsource the receiver's requirement to run his own server to an untrusted third-party server called the Payjoin Directory. In order to prevent the server from spying on users, the information is encrypted and relayed to the Payjoin Directory via an Oblivious HTTP server.
Bull Bitcoin’s Payjoin ambitions had been put on hold since 2020, until there was more adoption of Payjoin receiving capabilities among end-user Bitcoin wallets…
But it turns out that in the meanwhile, Bull Bitcoin developed its own mobile Bitcoin wallet. And it also turns out that the open-source Bitcoin development firm Let There Be Lightning, which we had collaborated with in the past, had itself collaborated with Dan to build a software library for Payjoin that was compatible with and relatively straightforward to integrate into our own wallet software. All that was missing was to put the pieces together into a finished product.
Thanks to the collaborative open source effort of the Payjoin Dev Kit team, Let There Be Lightning team and the Bull Bitcoin team, the Bull Bitcoin wallet has now become the first commercially available end-user mobile wallet on the Google Play store to implement the BIP 77 Payjoin V2 protocol.
Moreover, the Bull Bitcoin wallet has also implemented asynchronous Payjoin payments, which means that a Payjoin transaction can be “paused” until the receiver or the sender come back online. This way, the receiver's mobile phone can be “turned off” when the sender makes the payment. As soon as the recipient’s phone is turned back on, the Payjoin session will resume and the recipient will receive the payment. This is a major breakthrough in the mobile Payjoin user experience.
We would like to thank the Human Rights Foundation for allocating a generous bounty for the development of a Serverless Payjoin protocol and its implementation in a mobile Bitcoin wallet, as well as OpenSats and Spiral for supporting the work of Payjoin Dev Kit, which made this all possible.
Why does this matter?
Payjoin, also known as Pay-to-endpoint, is a protocol which allows the Bitcoin wallet of a payments receiver and the Bitcoin wallet a payments sender to communicate with each other for the purpose of collaborating on creating a Bitcoin transaction.
I first heard about Payjoin (then called Pay-to-endpoint) in 2018 and it completely blew my mind. What I liked most about it was that it was not a protocol change to Bitcoin, but rather it was an application-layer protocol that allows wallets to communicate in order to create smarter and more efficient Bitcoin transactions.
Whereas in a normal Bitcoin payment the transaction is created by the sender, and all the inputs of that transaction belong to the sender, in a Payjoin payment both the sender and the receiver contribute coins as inputs.
In the Bitcoin whitepaper, Satoshi wrote:
"some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner"
With Payjoin, this assumption is no longer true. With Payjoin, we have fixed one of Bitcoin’s most fundamental privacy problems... without changing the Bitcoin protocol!
In a Payjoin transaction, the output amounts visible on the blockchain does not necessarily reflect the value of the payment that was actually exchanged. In other words, you can’t easily tell how much money one wallet sent to the other. This is great for users that are concerned a malicious third party may be attempting to obtain sensitive information about their finances without their consent. This does not however pose an accounting problem for the Bitcoin wallets involved in that transaction: since both wallets are aware of which coins they used as inputs and outputs, they are independently able to calculate the "actual" value of the payment that was sent even if the payment on the blockchain appears to be a of a different amount.
Payjoin breaks the common input ownership heuristic, an assumption used by hackers and fraudsters to track ownership of addresses on the blockchain. The neat thing about this property of Payjoin is that it benefits everyone on the network, not just the Payjoin users themselves.
It allows the receiver of a payment to opportunistically consolidate his utxos when he is receiving funds, in a way which does not necessarily appear to be a consolidation transaction on the blockchain. Depending on the configuration of a payment transaction, it can also make a regular payment look like a consolidation.
In addition to these benefits, the introduction of collaborative peer-to-peer transaction protocols opens up exciting opportunities for the creation of Lightning Network channels, as well as efficiencies for transaction batching.
How to use Payjoin in the Bull Bitcoin wallet:
It’s so seamless, you may not even realize you are using it!
To receive via Payjoin, simply navigate to the “Receive tab” using the network “Bitcoin” and you will see a Payjoin invoice. When you want to get paid, send this invoice to the payer, or show them the QR code. If the sender’s wallet is compatible with Payjoin, it will be up to the sender to decide whether or not they want to use Payjoin.
To send via Payjoin, simply paste the receiver's Payjoin invoice, or scan the associated QR code, in the Bull Bitcoin wallet. If you decide that you don’t want to pay with Payjoin, simply turn off the Payjoin toggle.

The blocksize war wasn't so much about the blocksize (or, even, scaling Bitcoin). It was really about who controls the consensus rules and how we upgrade the protocol.
For context, a bunch of startups raised tons of money between 2013 and 2016 based on ridiculous user sign-up projections and then we had a long and painful bear market and they were looking for scapegoats (the developpers that were "throttling the network") to justify the lack of growth. I am thinking here specifically of Coinbase, Bitpay and Blockchain.info.
The vibe I got is that they thought of Bitcoin itself as a corporation, that they were the equivalent of Bitcoin's board of directors because they represented the interest of VC investors, and thus they were entitled to decision making power over the network.
I don't doubt that a few people were genuine about scaling p2p e-cash (e.g. Roger Ver) but I suspect what really motivated them is that they believed control of the Bitcoin network would be an asset to their business interests, and lack of control was being used as an excuse to why their interests weren't being satisfied.
There was also a bunch of developers that I believe may have been afraid of losing their relevance (Gavin and Garzik specifically). Regardless of their intentions or psychology, it seemed clear to me that the consortium of vc-backed startups (particularly Bitpay, Coinbase, blockchain(.)info and Roger) had picked a team of developers they thought they could control and wanted to appoint them as a technical management team whicn would execute their strategy, and these guys were willing to step up for that role.
I was physically in the room when the CEO of Blockchain.info (with the very obvious support of Coinbase CEO Brian Armstrong) announced that Bitcoin Core devs were being fired and would be replaced. This was after a couple days of failed discussions with other industry people. This was the moment when I realized what was really going on.
And finally, you had a Bitcoin mining giant (Bitmain) controlling both asic production and mining pools with a vested interest in promoting the idea that Bitcoin was a democracy and the way to vote was to buy hashing power. The main ideology being pushed here was that a formal governance mechanism of the protocol needed to be established and that hashrate was the only objective measure of who makes decisions.
The underlying big blocker ideology was that the chaos of spontaneous consensus of nodes is unpredictable, flimsy, bad for business. The absence of a formal governance process was seen as the root cause of the issue.
These companies really believed they could control the protocol, and controlling development of the protocol was seen as a very valuable asset to your company. I imagine they thought of themselves as the founders of a new consortium that would solidify itself into a permanent institution. The business interests would pay developers and set the goals, and the mining interests would ratify their decisions with hash power voting. That was their plan.
This became blatantly obvious when Bitmain used its refusal to activate segwit as leverage to get what it wanted (a blocksize increase and recognition of its hashpower as a vote mecanism) even though Bitmain iself acknowledged it was not really opposed segwit.
It was classic traditional politics: I'll give you segwit if you give me something in return.
This is the language the VC suits, investors and tech startup people understand and they were very happy to "negotiate" and find "consensus".
This eventually materialized into the New York Agreement, negotiated literally as a backroom deal during theConsensuss shitcoin conference. I was there and I refused to attend.
This (private) meeting consecrated the alliance of startups/investors and bitcoin mining interests in their appointment of a technical management committee. If you think this sounds like Jekyll Island, you're not alone.
They packaged segwit with a blocksize increase (Segwit2x) and decided to force a hard fork as a condition to "allow" us to have Segwit.
We know the rest of the story: we ended up activating anyway via UASF (or more precisely, the miners activated Segwit after they New York Agreement signatories became scared UASF would lead to a chain split which they were going to lose). And the blocksize increase was also abandoned shortly after when they realized their hard fork would cause a chain split and that they would not be able to claim that their new shitcoin is the real bitcoin.
All these people were subsequently were very pissed off they couldn't control the network, which they thought they were entitled to. Some ragequit, others created a bunch of shitcoins out of spite, Roger went on to spearhead BCH as the real Bitcoin, all these fools realized they might as well make some money off of it, everyone went all-in on the shitcoin casinos after that. The "small blockers" eventually went on to evolve into the Bitcoin Maximalists and cypherpunks that today tell you to run your own node and own your own keys.
