1/ Introducing the Merge Mining Monitor, another tool in service of the Bitcoin monitoring mission.
Merge mining lets child chains ride on Bitcoin's PoW, preserving the parent headers miners hashed.

The quantum threat to Bitcoin is like Russian roulette, except that someone else is holding the gun.
It might not even be loaded...
And if it is, you don’t know which pull fires...
But you don’t hang around to find out...
You do something!

@jack thinks bitcoin payment adoption isn’t where it could or should be. We want your ideas on how Block, Spiral, and you can improve adoption odds within 5 years. We need a shift to change our trajectory. Here’s more on our thinking. Now we want yours.

New on Maple Max and Team: DeepSeek V4.1 Flash, abliterated.
Refusals removed from the model itself, so it works through security questions instead of declining them.
- 1M context
- Runs in the same attested enclaves as every Maple model
- Built for security research, code audits and red-teaming
Attackers already run uncensored models. Defenders shouldn't be stuck with "I can't help with that."

Loupe findings have been landing in Bitcoin Core. During this cycle, five PRs landed: three have been merged, two are under review. Below is a thread on what each one caught and which Core dev implemented which fix.

A Bitcoin block can carry full proof of work and still be invalid.
I've catalogued 143 established cases from 2010 to 2026, including two previously unreported F2Pool timestamp failures this year.

Both recent F2Pool headers survived in merge-mined chains, with no known Bitcoin-side capture.
These chains also yielded ~1,400 stales new to the stale-blocks collection. Monitoring them is essential to a holistic Bitcoin monitoring effort.

127 of the 143 blocks have no complete body, yet their failures remain independently checkable.
10 further reports still need evidence. Old node files, pool logs or archives could help.

I built an agent to hunt for live mutants in Bitcoin Core's consensus-critical code.
It found several gaps that led to two Bitcoin Core PRs adding tests for things the existing suite missed.
I wrote about how it works and what it found:

I am looking for chain data from a number of chains that merge mined with Bitcoin to build out the dataset.
Missing data includes Xaya, i0coin, Jincoin, Jax.Network, Fusioncoin, Huntercoin, Bitcoin Stash, BLAST, VCash, Syscoin (v2).
Please reach out if you have any!

For those that have long running nodes, the Bitcoin data community would REALLY appreciate if you could check your node for stale block data:
