1) Full end-to-end AI software automation is near.

At Nexus, we have the goal of achieving full end-to-end automation of our software production system by end of year. We are experimenting with this via a fast iteration closed-loop self-improving system. I think it's quite interesting, so I want to share publicly as I haven't seen too many engineering teams talk publicly about findings like this yet.

In our tests, each autonomous improvement cycle has the following structure:

- 1. Pre-planning: High-level architectural goals
- 2. Planning: Medium-level planning and spec authoring, including specs for all tests, benchmarks, regression tests, etc.
- 3. Execution: Full end-to-end agentic implementation cycle spanning 1-2hrs of autonomous work. This is the bulk of the productive session where the actual code is written, tested, and progressed.
- 4. Evaluation: Complete running of tests, benchmarks, telemetry and profiling of the post-execution state system
- 5. Retrospective: Thorough retrospective of the end-to-end run, including telemetry of the agent itself, such as cost, tokens used, times context limits were hit, etc.
- 6. Self-improvement: Reasoning based on execution metrics and meta-level metrics about the agentic system itself

The view below shows a 3D visualization of 29 generations of a self-improving codebase authored by our E2E automation system

@lensassaman Perhaps today is another one of those days, wherever you are now, Len. R.I.P.

@sinnerman789 Pseudonymity ≠ lying.

It’s a longstanding accepted norm across crypto and security – used to separate identity from ideas, protect coders, and avoid the centralization and targeting that come with a known founder. I expect we'll see the importance of this with agentic systems.

[Alex Fowler @alexanderfowler]

1/ The hunt for the "real" Satoshi is back. But obsessing over who is behind the name misses the point. In 2026, the ability to act without revealing your identity is more essential than ever to trust online. 🧵

[Alex Fowler @alexanderfowler]

7/ The irony of the Satoshi hunt is that it proves his point. Bitcoin works without knowing who you are, and it's still working, over a decade later. We've been trying to solve online identity since the beginning and it remains unsolved in any one form or system. Maybe that's not a bug.

[Alex Fowler @alexanderfowler]

6/ We're entering an era where AI agents act on our behalf. "Who is behind this?" is the wrong question. The human isn't always the actor anymore. Perhaps what matters is what the agent does, and how we finally move beyond the constraints of identity altogether.

[Austin Hill @austinhill]

For additional context I suggested to @JohnCarreyrou to speak with Blockstream cofounder Greg Maxwell who is legendary in his ability to debunk faketoshi’s, knew the code base intimately and Adam personally.

I believe phrased it as “if your thesis and evidence can survive 10m of talking with Greg I’d be shocked” and offered to connect him to Greg.

I just now confirmed with Greg that he had no requests for contact or comment from anyone at the NY Times.

Purposefully avoiding talking to people who can debunk your story narrative isn’t reporting.

Messari's framing of what we built:

"Nexus represents an architectural bet: that high-performance financial infrastructure should not be simulated through smart contracts, but embedded directly into the base layer and verified cryptographically."

1/ Jolt now supports zero-knowledge 🧵

This makes Jolt suitable for privacy applications — no SNARK recursion, no "wrapping", no sacrifice of transparency. Marginal increase in proof size (~3 KB). Prover time is essentially unchanged.

This... We need to think about AGI from the perspective of "how measurement and verification shape the agentic economy."

[Christian Catalini @ccatalini]

1/ Some Simple Economics of AGI—🔥🧵
Right now, there is a low-grade panic running through the economy. Everyone is asking the same anxious question: what exactly is AI going to automate, and what will be left for us?

[Rob Hadick ＞|＜ @HadickM]

Looks like the market structure bill fight on yield won’t be our last, because we will have the same fight on rewards and yield in the OCC rule making process.

It makes no sense, and in fact is regressive, to not allow for rewards / cash back / loyalty for using money on platform and would harm both many current fintechs and consumers.

The banking lobby is trying incredibly hard to harm consumers and protect their moats.

Excited to introduce USDX, a new U.S. dollar product for a new era of finance.

USDX is 1:1-backed by U.S. Treasuries and cash equivalents, and is the upcoming native stablecoin of the Nexus economy.

USDX will endow the Layer 1, the Exchange and the broader Nexus Ecosystem with exiting new economic properties.

[Nexus @NexusLabs]

Introducing USDX — the native dollar of the Nexus economy.

A shared settlement layer for all apps, trades, and markets on Nexus.

One asset. Unified liquidity. Protocol-native incentives.

Capital is converging, and USDX is its native home.
