Hi everyone, we have a bitcoin core pr review club tomorrow (3/20/2024) at 17:00 UTC for this implementation.

> **[Implement 64 bit arithmetic op codes in the Script interpreter](https://bitcoincore.reviews/29221)**
>
> Many future extensions of the bitcoin protocol - such as OP\_TLUV - want to create smart contracts based on the amount of satoshis in a bitcoin output.

Happy to answer any questions about the PR, and talk through the ‘Design Questions’ section that I think still have open questions. Hope to see some of yall tomorrow at 17:00 UTC.
