Cloudflare's birthday, Fowler's notation, Stripe's stablecoin

Cloudflare's Birthday Week wrap-up lists 46 announcements across five days, each covered in one sentence. Most are about AI agents: agent CLIs, payments over HTTP 402, model routing, agent sandboxes. The post links to deeper write-ups but includes almost no mechanisms or benchmarks itself. Below are the infrastructure items, using only the detail the roundup provides.

Data and storage

• Workers KV Instant is built on Quicksilver, Cloudflare's internal config-distribution store. It keeps the Workers KV API and promises sub-2 ms p99 reads with fast replication to more than 300 locations. The roundup gives no consistency or replication-lag figures.
• K2 is a durable, ordered event stream that stores its data in R2. It decouples producers from consumers without a broker cluster to run. The roundup doesn't say how ordering, partitioning or delivery semantics work.
• Basin is now generally available. It's a serverless data platform on Apache Iceberg and R2 for ingesting, managing and querying large datasets.
• Artifacts is in open beta, with a contest to build a Git platform on Cloudflare.

PKI and post-quantum

Twelve years after launching Universal SSL, Cloudflare plans to become a public certificate authority. Its stated goal is to make free, automated certificate issuance more resilient. The planned CA would issue Merkle Tree Certificates, which are meant to make post-quantum authentication practical without the large certificates and handshakes that post-quantum signatures normally bring.

Martin Fowler's latest "Fragments" post is a set of short notes, and most of them are about LLMs. What follows covers the parts with lasting engineering value and leaves out the model commentary.

Building versus nurturing

Fowler draws a line between building deterministic computational systems and nurturing inferential ones. Bridges collapse and programs have bugs, he notes. But when you find a bug in a deterministic system you can usually fix it, or at least turn off the faulty component. He argues that inferential systems give you neither option. He uses the 1956 film Forbidden Planet as a warning about what happens when you raise a thinking machine you can't control.

What sits at the top of the stack

The most concrete note comes from Sam Ruby, who was responding to DHH's claim that generated code will eventually target assembler and then microcode. Ruby measured a Rails application: about 60,000 tokens as Ruby/Rails source and about 4,000,000 tokens once compiled to C. That is roughly a 67× increase. Even if no human ever reads the code, the larger version is harder for any tool to fit in its working context and harder to search for the part that matters. Ruby's view is that Rails is "the most compact, precise and conventional specification of a web application, whatever it ends up compiled to." His summary: "Let the drill go as deep as it can. Just keep the notation at the top."

Fowler ties this to projectional editing, the idea that the form you edit software in doesn't have to match the form it's stored in. Geoffrey Huntley argued that readable code is no longer the goal. Yet his own example explained a Haskell function by rewriting it in Python. Fowler reads that as support for keeping a readable representation, even if it's generated on demand.

Cloudflare says its Impact programs, which give security services to public-interest organizations, will pass $100 million in donated services this week. The post marks the company's 16th Birthday Week. It reads mostly as company history and recruiting copy, and it says nothing about how these customers are protected technically. The figures are the useful part.

Where the programs came from

Cloudflare launched as a free service. The plan was to collect attack data from free users' websites and use it to build paid products. According to author Patrick Day, the company then noticed that some free customers were doing sensitive work, such as reporting on corruption in Africa or on Russia's invasion of Crimea. Those same customers were taking some of the largest attacks on its network.

That led to Project Galileo in 2014, which gives more advanced security to journalists, human rights defenders and civil society groups. Today it covers more than 3,500 domains in over 120 countries. In 2025 Cloudflare blocked more than 38.5 billion attacks against participants, about 105.4 million a day. That count includes DDoS, attempts to exploit website vulnerabilities and email phishing.

Other programs followed:

• Athenian Project (2017): more than 440 election websites in 33 U.S. states, plus election management bodies in eight other countries, including Canada, Georgia and Moldova.
• run with Defending Digital Campaigns, covering more than 530 candidate websites.

Stripe has made Open USD (OUSD) the default stablecoin across its products, running on Tempo by default. OUSD is a new stablecoin issued by Open Standard, a consortium whose founding members are Coinbase, Mastercard, Shopify, Stripe and Visa, plus more than 200 network partners. Stripe says it will keep turning OUSD on by default in more products as support expands.

What changes for integrators

OUSD now works in five Stripe products:

• Treasury: receive, hold, send and spend funds.
• Issuing: run card programs.
• Global Payouts: pay recipients in other countries.
• Crypto Onramp: convert fiat to OUSD for end customers.
• Payments: accept OUSD.

It also works with Stripe's acquisitions Bridge and Privy. Bridge's orchestration APIs convert between OUSD, fiat and other stablecoins. Privy adds OUSD support to wallet products. Stripe's pitch is that a business can use the whole stack instead of combining separate providers for each step of a transaction. Ramp plans to use Stripe for stablecoin accounts that hold OUSD, earn rewards and make payments around the clock.

OUSD runs on Base, Ethereum, Solana and Tempo. Tempo is the default, but users can still pick a different stablecoin and chain based on cost, settlement speed or infrastructure. Stripe will not make anyone convert existing stablecoin balances to OUSD.
