# ScaleFirst

> Technical writing on investment management systems, digital assets and distributed systems — Java, Spring Boot, Kafka, tokenized funds, fund accounting and AI agents in finance. Several posts are interactive essays whose simulations run client-side; the prose in this file is the complete argument, minus the controls.

## Blockchain

- [Building Tech for Tokenized Treasury Bills: A Java 21+ Guide](https://scalefirst.org/blog/building-tech-for-tokenized-treasury-bills-a-java-21-guide/): With the emergence of tokenized US Treasury securities like Franklin Templeton's FOBXX and BlackRock's BUIDL, traditional investment management systems need robust integration capabilities. This article explores building production-ready APIs using Java 21 and Spring Boot.

## Development

- [Addressing the AI Awareness Problem -SurvivalIndex](https://scalefirst.org/blog/addressing-the-ai-awareness-problem-survivalindex/): 230 new repositories per minute. That’s what GitHub reported in their 2025 Octoverse. 121 million new repos in a single year. A billion commits. 36 million new developers. But how is AI choosing the Open Source Tools in your code? SurvivalIndex Measures
- [Your AI Agent Did Something Last Tuesday and Nobody Can Tell You What](https://scalefirst.org/blog/your-ai-agent-did-something-last-tuesday-and-nobody-can-tell-you-what/): "You're a developer. You've got an AI agent doing something actually important — code review, infrastructure configs, customer data." "Because what you're about to discover is that you have essentially zero ability to answer 'what did my agent do and why?'"

## Digital Assets

- [Six Mechanisms That Decide Whether an Asset Can Be Tokenized](https://scalefirst.org/blog/six-mechanisms-that-decide-whether-an-asset-can-be-tokenized/): Not the token standard — the machinery underneath it. Six interactive simulations of the mechanics that govern tokenized funds: atomic settlement, the compliance subgraph, mirror-record drift, NAV staleness, liquidity transformation, and a scoring model for what gets tokenized next.

## Distributed Systems

- [The Keyed Worker Pool: Parallel Kafka Consumers That Keep Order](https://scalefirst.org/blog/the-keyed-worker-pool-parallel-kafka-consumers-that-keep-order/): Kafka orders records inside a partition. The moment you hand a batch to an executor, that guarantee is gone. Four interactive simulations of the machinery that gets parallelism back without losing order: mailbox dispatch, the low-watermark commit, pause-based backpressure, and the rebalance gap no broker setting can close.
- [Four Algorithms That Run Inside Every Kafka Cluster](https://scalefirst.org/blog/four-algorithms-that-run-inside-every-kafka-cluster/): Not the API surface — the machinery underneath it. Four interactive simulations of the algorithms every Kafka cluster runs: Boyer-Moore majority vote, consistent hashing, ISR and the high watermark, and sparse-index binary search. Drive each one and watch the invariants hold or break.

## FinTech

- [Revolutionizing SEC Compliance: Building an AI-Powered Domain-Specific Language with Java Spring Boot](https://scalefirst.org/blog/revolutionizing-sec-compliance-building-an-ai-powered-domain-specific-language-with-java-spring-boot/): In the rapidly evolving landscape of financial regulation, compliance teams face an impossible challenge: manually implementing complex SEC rules that change frequently, require months of development cycles, and demand perfect accuracy. At **ScaleFirst**, we're pioneering a revolutionary solution that combines the power of Domain-Specific Languages (DSL) with AI assistance to transform how financial institutions handle regulatory compliance.
