There's been lots of debate about Core v30 removing the OP_RETURN size/count policy defaults, so I ran the numbers for the latest @mempool research report linked at the end. A thread 🧵 👇

Huge HUGE congrats & thank you to Vasil Dimov!

This is an awesome, simple privacy improvement when broadcasting a new tx.

He opened this PR almost 2yrs ago. But it wasn't simply a matter of sitting and waiting for it to be reviewed and merged.

He had to WORK at it. CONSTANTLY.

Statement from Foundation
We are incredibly saddened by the harsh five-year sentence given to Samourai Wallet co-founder Keonne Rodriguez.

We believe this outcome is unjust and deeply troubling. It directly conflicts with previous guidance from FinCEN; where one federal agency provided clarity, another chose prosecution.

The current administration often speaks in support of Bitcoin, yet the Justice Department continues to pursue policies that may predate this administration – targeting privacy technologies and open-source developers. The administration’s silence on these cases increasingly feels like tacit consent.

While the Samourai team could be abrasive online, they were principled libertarians who fought for freedom and recognized that Bitcoin is not private by default.

Years ago, we explored integrating CoinJoin into our Envoy mobile wallet and hoped to collaborate with Samourai, but we paused development due to legal uncertainty. We also donated 0.5 BTC to their defense – the least we could do to support those building for financial privacy.

We urge the administration to consider a pardon for Keonne Rodriguez and William Lonergan Hill and to issue a clear public stance affirming that privacy tools are not crimes.

Open-source developers deserve protection, not persecution.

@SimpleXChat @ChainWorld0 No, we dislike Ethereum because it is a premined dumpsterfire shitcoin with a supreme leader that reigns over his empire and changes policies as he sees fit

Re: Passport Prime

[Zach Herbert 🇺🇸 @zherbert]

To our Passport Prime Early Access customers: we appreciate your continued patience as our @FOUNDATIONdvcs team works to get devices into your hands. It’s taken longer than we thought it would – and while I still don’t have an exact date, we are much closer now and are aiming to begin shipping in the coming weeks. Below is a detailed update of where we are from a hardware and software perspective.

While Passport Prime will be the third device Foundation has created, it’s really an entirely new, first-generation device running a new operating system (KeyOS) and new hardware architecture. It’s the first of its kind personal security platform that will enable an open, permissionless developer ecosystem for third party apps.

It’s been an enormous effort to build KeyOS, ensure it is secure, and create the first-party apps that are shipping with Passport Prime. This week we officially finished our security audit by @keylabsio, who we think is best in the business. We will publish the final report next week and are finishing up implementing the suggestions from the audit to ensure Passport Prime is the most secure device on the market.

Completing the audit is a major milestone and was one of the items blocking us from being able to finalize the v1.0 bootloader and KeyOS release. I’m sharing a screenshot of the Conclusion page below, but I also wanted to share the last sentence of the report:

“This results in a highly secure hardware wallet architecture that exceeds industry standards for protecting users' digital assets.”

With Passport Prime and KeyOS, we are aiming to not only match industry standard security (cough, Ledger, cough), but exceed it. I am proud to say that we have done that.

Now that the audit is complete, the team is rigorously testing the firmware update process, so that when you unbox your Passport Prime and connect it to Envoy, it will seamlessly update to the latest KeyOS firmware.

This is of the utmost importance because we can fix most bugs with updates, even after shipping, but there cannot be any bugs in the initial process of connecting Passport Prime to Envoy and initiating a firmware update.

Once we internally deem that firmware updates are bulletproof, we will give the factory the go-ahead to provision all circuit boards with KeyOS and complete final assembly and packaging.

In the meantime, we are squashing bugs in our first-party apps and working to complete all Bitcoin app features. Since this is the Early Access batch, we do expect that there will be some bugs and/or some incomplete features across apps, but we want to ensure that (1) there are absolutely no bugs that will affect device security and (2) that the Bitcoin app has parity with the Passport Core experience, supports all the same software wallets, and so on.

I will continue to post regular updates and will also publish a video walking through the latest version of KeyOS. Please let me know if you have any questions! Thanks for reading.
