@bitschmidty How many slides highlight how it improves Bitcoins quality as money (i.e. directly tied to the monetary properties being improved)

I recently presented "The State of Bitcoin Core" at the OPNEXT conference.
Its ~100 slides on what Bitcoin Core developers are actively working on.

@bitschmidty I don't know how many times I have to tell you that "shitcoin core is DEAD for bitcoiners".
It seems like you are not going to learn this FACT until you fuck around and find out with the successful activation of BIP110.

stop being retarded, fellow bitcoiners.
AI conspiracy confirmation slop is rotting your brains.
bitcoin development is robust, it doesn't need your "help".
fighting to erode or override IETF-like consensus process is a BAD IDEA, and will be forcefully rejected by the market.

I was pleased to be invited to present my work to Brink engineers on Hornet Node: A Minimal, Executable Specification of Bitcoin Consensus. Feedback welcome. Thank you @bitschmidty for the invitation 🙏🏼

Good to hear @bitcoindudebro present on his work towards creating a specification for Bitcoin consensus

Today we’re publishing Maelstrom's Bitcoin Grant Program Annual Report, for the period ending June 2026. The report covers the technical work of the four Maelstrom funded open source developers, working to improve Bitcoin, with respect to scalability, robustness and privacy.

@bitcoin_eagle @sedited_ I think that would be an amazing long term potential goal. But @sedited_ could comment

sedited (@sedited_), Bitcoin Kernel developer and Bitcoin Core maintainer, blog post on validation logic in Bitcoin Core:
"Block validation logic in Bitcoin Core is surprisingly complex. After more than a decade of engineering towards improving performance, Bitcoin Core has accumulated many caching layers, sub-steps, and optimizations before the node even calls the script interpreter. In the following, I’ll describe in broad strokes what these are, first roughly describing what validation is done in which order, then explaining why it was implemented in the way it is and the tradeoffs involved"...

@bitschmidty @sedited_ Will we ever get proven implementation?

bitcoinfuzz is a project to differentially fuzz test Bitcoin protocol implementations.
It throws quasi-random inputs at different Bitcoin implementations (& libraries) at the same time to see where there are differences in behavior.
Its finding real bugs. From @brrrunog & team:
Bruno Garcia@brrrunog
First bug found on libbitcoin-system with bitcoinfuzz (even without having it merged yet). libbitcoin was not properly checking empty blocks. Kudos to KY-U for finding and fixing the bug. github.com/libbitcoin/lib…
