Fun fact: when building Bitcoin Core’s bitcoind on modern systems, the x86_64 build compiles 10 more source files than the arm64 build.

i rebuilt satoshi's 2009 bitcoin.exe byte for byte!
afaik nobody has been able to perfectly recreate the executable published in 2009 from source, because we didn't know the exact build environment that was used.
using opus 5.5, i reverse-engineered satoshi's build machine from the binary.
it now outputs an exe with the exact same sha256 as the 2009 release!

Surround yourself with people who see a flying car and say, "Awesome!"
Not people who see a flying car and say, "It's not actually flying" or "I don't see the point."
This post is not about cars :)

‼️ just got a pretty smart github OAuth phishing/ATO attempt on my personal account.
attacker created a repo named after my github username, opened an issue mentioning me with a fake account-access alert, which triggered a real email from notifications@github.com.
“This wasn’t me” → attacker-controlled GitHub Pages → real github.com OAuth consent page for an app called “profile security settings”, asking for public/private repo access + permission to update GitHub Actions workflow files.
no fake github login page. the email is github, the auth page is github. the malicious part is the OAuth app + redirect flow.
the page is just an obfuscated redirector, while the OAuth callback forwards the returned code/state to the same backend: github.com/api6268/code-839c…
also caught two other username-specific phishing issues from the same github account before they disappeared.
some indicators:
issue account: 6119f4f
OAuth app: profile security settings
consent: Authorize request-6286
landing: api6268[.]github[.]io/code-839c74ee/
related landing: api25cd[.]github[.]io/account-13e95c92/
callback: request-6286[.]github[.]io
backend: gitmain[.]serveblog[.]net
route ID: 9e52a992

32.0rc2 testing binaries are now available bitcoincore.org/bin/bitcoin-…
Includes the new getopenrpcinfo RPC (shoutout @willcl_ark). It returns a machine-readable OpenRPC spec of the entire RPC API, useful for generating client code and docs or diffing between releases.

x402 lets agents pay for API calls using almost every form of digital money under the sun—except for the first digital money. Then @benthecarman got Lightning merged into the spec and now, BLAM, every agent is a bitcoiner.
The spec for lightning in x402 was merged last night!

I wrote a blog post on the recent exploits in the Bitcoin ecosystem, how Bitcoin Core is holding up, and how I think the community can get ahead of the models:

Our third-party e-mail provider has been breached. Please be aware that the email named ‘Critical Security Alert: STM32 Entropy Vulnerability’ is not coming from us, and it’s a phishing attempt. Do not click on any link.
We have taken down the domain, and we are investigating the situation, including how the hackers got access to our legit domain.
