The Evolution of Composability in Blockchain Computing and Duolingo's Unique Business Model

Blockchain technology has come a long way since its inception, and as it has evolved, new eras of computing have emerged. One key aspect of blockchain development is composability, which refers to the ability to use existing resources as building blocks to create higher-order applications. Composability allows developers to do more with less, leading to rapid innovation and advancement. In this article, we will explore the four eras of blockchain computing and how they relate to Duolingo's successful business model.

The first era, known as the "Calculator era," is characterized by the emphasis on security rather than programmability. Bitcoin, the pioneer of decentralized money systems, can be seen as more of a calculator than a computer. Its limited scripting language ensures security but limits its programmability. Despite this limitation, Bitcoin's calculative nature laid the foundation for future developments in the blockchain space.

The second era, the "Mainframe era," began with the introduction of Ethereum. Ethereum expanded upon Bitcoin's key ideas by including a Turing-complete virtual machine, allowing developers to deploy and run any program across a decentralized network. However, this level of trustless computation comes at a cost. Each node in the network must execute every program function, making it slow and expensive to use. Nonetheless, Ethereum remains unrivaled in terms of trustless computations.

During the Web 2.0 era, composability was not sustainable due to the lack of effective governance and financial incentives. The absence of a way to send money through APIs and the misalignment between developers and platforms resulted in the re-centralization of data and the loss of third-party innovation. While early network effects of composability were evident, the limitations of the mainframe era's throughput hindered further growth.

The current era, known as the "Server era," focuses on scalability and application-specific architectures. Developers are foregoing composability and shared network effects in favor of owning the infrastructure and having more control over the end-user experience and supply-side economics. In this era, blockchains still maintain composability but on a different dimension. New standards for communication between blockchain computers are required to enable composition across applications.

Looking ahead, the "Cloud era" represents the ideal vision of blockchain computing. This era promises a scalable and generalized substrate for trustless computation, where composition is only limited by creativity, not scale or communication complexity. Innovation can compound without hitting diminishing returns. There are also ongoing research efforts to explore new architectures that move computation off-chain, potentially revolutionizing the field of blockchain computing.

Now, let's shift our focus to Duolingo, a language learning app that has achieved remarkable success without charging its users. Duolingo recognized that there was a vast market of people who wanted to learn a new language but couldn't afford expensive software like Rosetta Stone. By offering a free app and relying on testing and crowdsourcing, Duolingo was able to tap into this underserved market and build a helpful language learning platform.

Duolingo's early business model revolved around crowdsourced translations, which allowed them to generate revenue while providing a free app to users. They leveraged the scale of their target market to beta test their idea and understand what resonated with users. By designing their app with the goal of eventually selling crowdsourced translations, Duolingo laid the foundation for their language learning while translating the web premise.

The concept of leveraging crowdsourced labor was not new to Duolingo's founders. They drew inspiration from reCAPTCHA, which used free labor to verify words that scanners couldn't recognize. Duolingo applied the same idea to language learning, harnessing the power of crowdsourced translations to generate human translations of the web on a large scale.

To keep users engaged and habitually using the app, Duolingo gamified the experience with features like streaks and constant A/B testing to optimize user engagement. They also introduced Duolingo Incubator, allowing volunteers to create courses for languages not yet available on the platform. These additional courses were created by volunteers who collaborated for free, aligning with Duolingo's mission of providing free language education.

Monetization was a challenge for Duolingo as they aimed to uphold their core value of providing high-quality language education for free. They explored various avenues, including partnering with other companies to sell translated content and offering paid plans that remove ads and enable offline learning. Duolingo ultimately decided to serve ads to users, but they made sure the ads were unobtrusive to maintain a good user experience.

In conclusion, both blockchain computing and Duolingo's business model have evolved over time to meet the needs of their respective industries. Composability has been a key aspect of blockchain development, allowing developers to create innovative solutions by building upon existing resources. Duolingo's success lies in its ability to tap into a large market and provide free language education while finding sustainable ways to monetize. By understanding the evolution of these two fields, we can gain insights into the power of composability and creative business models in driving innovation.

Actionable Advice:

• 1. Embrace composability in blockchain development: Consider how existing resources can be used as building blocks to create higher-order applications. This approach allows for more rapid innovation and can lead to compounding effects.

• 2. Tap into underserved markets: Identify markets with unmet needs and explore creative solutions to provide value. Duolingo's success is a testament to the power of addressing a large market that is unable to afford existing solutions.

• 3. Constantly iterate and optimize: A/B test different strategies, features, and user experiences to ensure continuous improvement. Duolingo's focus on gamification and user engagement has been instrumental in driving habitual use of their app.
