Yesterday I began fully integrating the @OpenAI trust cyber program into my Bitcoin Red Team efforts.
This morning I woke up to see this.
I am now being blocked from doing additional analysis on a codebase which I've already responsibly disclosed to, and have received confirmation had legitimate findings.
To be clear, this is after having already KYC'd and completed the onboarding process months ago to use the cyber capabilities OpenAI has to offer.
I am now prevented from being able to continue the investigation in a further effort to make sure their code changes are sufficient, as well as understand if there are other issues that have yet to be discovered.
It absolutely guts me as a patriotic American to have to do this, but I will be going back to using Chinese open source models to conduct my research to protect Bitcoin infrastructure.
Black hats will not hit these issues. The white hats will. We've hit a local minima in policy. Intelligence is unrestricted for those who don't follow rules, and those who engadge in harm reduction are left on the sidelines.
What are we doing in this country? How is this keeping people safe?
Please do something @DavidSacks @sama @realDonaldTrump

We made a short visual explainer to help people understand the Coldcard bug, and what it means for the security of affected wallets.
Bitcoin's entire security model depends on a user's ability to select astronomically large numbers from a truly random set.
If you imagine every possible Bitcoin private key as individual atoms, when a private key is generated properly, the pool of possibilities is so large that it's like an attacker is hunting for one specific atom hidden somewhere across 2 billion galaxies. No classical computer could ever search that many possibilities.
Unfortunately, affected Coldcard firmware drew its seeds from a much smaller, more predictable pool. If every possible Coldcard private key was an atom, the possible set of keys would only be about the size of a large virus. In comparison, a standard computer could work through that space in just a few hours.
Our video helps visualize what this difference looks like, we hope this is helpful for everyone to establish the importance of true entropy in key generation.
We are deeply sorry for anyone who lost funds to this bug. We know several people that were personally affected, including members of the BPI team. Losing funds after working hard protect your wealth is extremely difficult.
We are developing a set of policy reflections based on this vulnerability that we hope to publish as soon as possible.

Here's how to create a simple 12 word bitcoin seed using Seedsigner and dice.
Its filmed in real time with a timer running so you can see the entire process & how long it takes
Do you really think this is too hard, or too much trouble for you to secure your family's future?
They don't want you to know you can do this. How hard is it really and how long does it take?
I've seen a lot of aggressive fear porn raging against the idea that people can or will roll dice to generate a seed - I was curious how long it'd take to sit there and do the process from beginning to end...
I turned up some music loud and went into an adjoining room with no electronics. The music both masks the dice roll and keyboard entry sounds, and is fun to listen to.
Results: It takes about 4 minutes to roll a 12-word seed phrase and enter it into a Seedsigner. Skill level - kindergarten
I was able to go through everything below in 75 minutes
🎲 roll three unique 12-word seed phrases
✅ load them into seedsigner,
✅ Verify the fingerprints
✅ Verify the words
✅ Write down the words
✅ Export xpubs into Sparrow
✅ Create a watch-only multisig wallet over airgap between Sparrow and Seedsigner
✅ Receive testnet coins from the @mempool faucet
✅ Create a batch transaction sending back the coins to the faucet as well as another 2 wallets in Sparrow
✅ Send he tx over airgap back to the Seedsigner for the first signature,
✅ Sending the partially signed PSBT back to Sparrow to display the next PSBT QR,
✅ Sending the fully signed PSBT back to Sparrow and finally
✅ Broadcasting
And I did this all before Widespread Panic could even finish the first set of the concert! I basically started rolling dice at Stop-Go, and was done before the end of One By One.
Note: transactions all sent on testnet4. (Both Sparrow and Seedsigner were also set to Testnet/4.)
.@KLoaec from Wizard Sardine just published a full technical breakdown of a critical Coldcard vulnerability.
Every seed generated on the device since 2021 is compromised. Wallets are being drained right now.
The chip has a perfectly working hardware random number generator. Nobody was calling it.
"The Coldcard replaces MicroPython's randomness module with its own, deemed more conservative. To do so, it disables the original one... The catch is that MicroPython does not remove rng_get() when that flag is 0. It replaces it with a software imitation."
The result: "a Coldcard seed no longer held a single bit of physical randomness."
A compile-time safety check should have caught this but used `ifndef` instead of `if`. "One character stood between that safeguard and its purpose." It passed on every build for 5+ years.
Seeds from 50+ dice rolls or pre-2021 are safe. Everyone else: move funds now.
