still blown away by @0xb10c's p2p ebpf tool for bitcoin-core. detailed node introspection with only a few traces added to the codebase 🤯
Wednesday's Bitcoin Core PR Review Club will dive into User-Space, Statically Defined Tracing (USDT).
Our host @0xb10c opens the door to peeking into runtime internals of Bitcoin Core at statically defined tracepoints.
Come discuss and learn; notes and questions are up!
This is inspired by https://blog.bitmex.com/bitcoin-miner-transaction-fee-gathering-capability/ , which is a good read for everyone interested in this topic.
I'd like to thank the people who have provided feedback on this project. You shall remain anonymous, as I don't want to imply endorsement.
For example, it becomes apparent that #682170 did NOT filter transactions.
All transactions missing from the block had only been in my mempool for a few seconds. None are sanctioned.
Differences between templates and blocks are to be expected!
In response to block #682170, mined by MARA Pool, I'm announcing a project I've been working on. I hope this brings transparency into mining pool transaction selection.
This compares block templates generated by my node to the blocks mined by pools.
MARA Pool mined its first 'clean' block today.

hey all, i built both the vaccum TEP of shiftcrypto and the entropyseal.
apologies we have not yet published a video that clarifies some of the assumptions discussed here.
@giszmo - freezing attack is indeed not easily doable thanks to the protrusions, which we call pins, locking the entire system if the particles are frozen.
@giszmo - not friction makes cap insert rotate against the cap. there are teeth, actually heavy duty teeth that prevent from twisting the jar open without opening the particle insert into a loose state forcefully.
@kekcoin - slow and careful will still disturb the pattern due to pins inside cap and also from the other side of the insert. upside down opening does also not do the trick.
@jgettbtc - the design is foreseen in transparent polycarbonate, the locked particles should survive a simple drop easily. after all the design is made to be shipped internationally in locked state. thick tempered glass would be an option for the jar but would increase cost a bit.
@121
- love the idea of russian doll style. tough that would need two initial sizes and injection mold tooling is quite a cost factor.
@pete
- the vacuum tep's main security was not the bag but the problem to pull away the velcro particle pouch from the container without disturbing the pattern.
i gladly answer any further arising questions, also via entropyseal@protonmail.com
@stephanlivera @pox @ibz @lukedashjr @Mandrik @verretor @TallTim @zlok @nvk FYI, if you have a personal website that people might know (e.g. like Stephan), you can put a rel="me" link on it that points to your Mastodon profile, which the default Mastodon software will verify for people viewing your profile. E.g., here's mine.
I've written about the evolution of the signature size in Bitcoin over the years.

I am giving back to the community.
All Bitcoin sent to the address below will be sent back doubled! If you send $1,000, I will send back $2,000. Only doing this for 30 minutes.

In my third Mempool Observation, I describe and use a methodology to identify Blockchain wallet transactions, derive wallet-usage insights, and discuss potential wallet privacy improvements.

Good article but the particular mindblower is ... 3 of 4 with UNCOMPRESSED keys?? wtf bitmex

How is the Bitcoin network being used?
I've build a Bitcoin Transaction Monitor to gain deeper insights on the Bitcoin network usage. Transactions are plotted by time and feerate, which reveals interesting activity patterns.
