Bitcoin Red Team update: we've grown to 16 globally distributed people working 24/7
We're running a large-scale ecosystem security audit across bitcoin code bases.
27.5 hours in, we've filed 4,962 findings across 390 projects. 85 critical and 635 high severity issues.
We're at 2.31 h+c findings per person per hour

It's a User Experience failure.
If multi-sig, passphrase, and adequate entropy are required (they are) the workflow should never let you skip these options.
A hardware wallet's only job is to keep funds secure. If there's a route which allows less security, it is a design FLAW.

BIP110 taketh away OP_IF, but giveth OP_PLENTY.
Introducing a novel way to encode arbitrary data in *contiguous* bytes. Up to 2MB fully BIP110 compliant.
OP_PLENTY encodes each 4 bit nibble of the raw data into a tapscript opcode. Decoding is trivial: take the opcode mod 22.

December 9, 2010. A user asks Satoshi Nakamoto why Bitcoin shouldn't just allow 64 or 128 bytes of "arbitrary data" in a transaction.
His answer, verbatim:
"I also support a third transaction type for timestamp hash sized arbitrary data. There's no point not having one since you can already do it anyway. It would tell nodes they don't need to bother to index it."
Read the design spec inside that answer. Small. Standardized. Not indexed by nodes.
Bitcoin Core shipped that exact spec in March 2014. It's called OP_RETURN.
#Runes lives entirely inside OP_RETURN. One runestone per transaction, prunable, zero UTXO bloat, full market fees. #Ordinals pays the same toll through witness space. The only gatekeeper Satoshi ever wrote into the system was the fee. Both pay it.
Now read BIP110. It proposes to reject the exact transaction class Satoshi said he supports, from the channel built to his own spec.
That is not enforcing Satoshi's design. That is reversing it.
And we already ran this experiment. In this same December 2010 thread, miners holding double digit hashrate publicly refused to filter non-standard transactions. Satoshi's response was not a crackdown. It was the quote above.
Fees settled this in 2010. Fees are settling it again in 2026.

The biggest problem with Bitcoin is that it's a really smart asset in a world full of retards.

On this day in history, 10 years ago, the Opendime was released. The USB can be passed by hand, checked by plugging in, and spent only after removing the resistor off the circuit board to reveal the private key, turning the bitcoin into the object itself.
