make BTrees faster => make everything faster

inspired work @MOVNTDQ 🙇
I built bbtree, the foundation of databases and filesystems, and the fastest concurrent btree.

authenticated state all the things

(QMDB is now <15% overhead over raw disk access 👀)
We achieve this by running a virtual userspace block device on top of a custom highly optimized interactive merkle proving protocol built on a fork of @commonwarexyz’s excellent QMDB library.

Every single read and write is verified inside of the TEE before the kernel sees it.

It appears these intermediary certificates were issued with single-byte P-384 private keys. This means anyone can exploit this issue locally and issue valid certificates under them with no effort.

This is very, very bad! Seems undetected since issuance in 2025?
private keys from 8 intermediate CA certs have been compromised (eMudhra)

Happy "Update everything" day to all my pager-carrying friends

For high performance blockchains, indexing and querying data quickly becomes the bottleneck. It doesn’t matter if your chain runs at 1M TPS if your data can only be ingested at 100K TPS

Excited for this launch from @commonwarexyz! @exowarexyz is an important solution to this
At Frontiers this morning, we launched our first two @exowarexyz products: log + store

Stream and index a stupid amount of data in realtime (~20-40ms cross-AZ durability at 5M keys/sec) for cheap 💸

Introducing Magnetar from Microsoft Research, the first zkVM that is: (1) general-purpose (RV64), (2) post-quantum from standard hashes alone (no curves, no lattices, no Poseidon), and (3) built for recursion.

Despite its conservative security, it is the fastest zkVM: 7.2–8.7 MHz on a laptop, 10–39× faster than existing zkVMs across 15 workloads! An optimized version reaches 9.5–12.8 MHz.
