@sreeramkannan @0xkydo @eigencloud Appreciate the chance to provide an early look and offer feedback! 🙇

ICYMI: We’re sharing the blueprints we used at Box for enterprise AI transformation in our new Executing As An AI-First series. 6 takeaways from this week’s installment: Start permissive. Consolidate ruthlessly. Transform workflows. Make it continuous.

Hats off to @sreeramkannan, @0xkydo, and the rest of the team at @eigencloud for both having the confidence to explore a new DA architecture and taking it all the way to prod (with frontier performance).

For some time, I've been watching for a DA construction that provides a formal and complete treatment of both "observation penalties" (rather than just the typical "alert" left to impl) and "DAS lite client recovery". Turns out, you can pull that off at 1GB/s+ 👀

We’re incredibly proud of what we've built with @axelar, growing the network to support 80+ connections, processing billions of value, and growing the ecosystem with dozens of applications and thousands of users. In the next chapter, I’m excited to share that we have entered into

I’m rapidly running out of reasons to not prove everything 👀

Teams like @tempo are already integrating with the Commonware Library to build the next generation of highly-performant blockchains. This collaboration between @commonwarexyz and LayerZero ensures storage won't be a bottleneck for anyone pushing the limit of what is possible

Respectfully, your phone plan sucks. Switch to Noble.

The Commonware Library has officially adopted LayerZero’s QMDB as their default verifiable database. @commonwarexyz will maintain the open-source, production-ready version of QMDB, with ongoing contribution and support from LayerZero.

Commonware 🤝 LayerZero The next gen DB for next gen chains.

And yes, like everything else in the Commonware Library, it is licensed as MIT/Apache-2.

After discussion with LayerZero, we both determined that instead of building our own versions of QMDB that we should direct our work towards a single implementation. We're excited to share that will be our family of authenticated databases, now renamed to QMDB.

Airia Wrapped 2025:

This family of databases, however, never diverged far from QMDB. We found coherent ways to break apart QMDB and introduced support for state sync but never departed from the core MMR-over-log abstraction (we couldn't find a way to do better).

The simplest database you need, for example, only supports inclusion proofs! https://t.co/mxq4Hmsefw

Rather than requiring all applications to support all proof types, we opted to instead build our own family of MMR-over-log databases (ADB) with granular control over proof support.

QMDB can “do it all” (inclusion and exclusion proofs over both current and historical state). At @commonwarexyz, however, we found a number of applications that didn't need to.

And last but not least, merklization can be performed with little memory and no disk access because new operations exclusively modify the right side of the tree.

By linking keys in lexicographic order, this log can generate exclusion proofs (prove inclusion before and after). Because the root spans the entire log, proofs for any key can be verified against the current root.

With QMDB, researchers at LayerZero found an (elegant) solution to authentication by layering a Merkle Mountain Range (MMR) over a log of key updates.
