Summary

Introduction to Blockchain Trends

In this episode, Chris Dixon and Olaf Carlson-Wee delve into the evolution of blockchain technology since the launch of Bitcoin and Ethereum. They identify seven key trends in blockchain computing that signal a shift from basic protocol design to product launch, emphasizing the importance of improving developer productivity, enhancing scalability, and establishing effective on-chain governance.

Developer Experience and Productivity

A central theme in the discussion is the notion that developer experience is paramount for the success of blockchain applications. The pair reflects on how Ethereum's launch opened up new possibilities for developers, treating wallets more like browsers than mere bank accounts. They emphasize that simpler programming languages and abstractions are crucial to scaling usage and fostering innovation in the blockchain ecosystem.

Scaling Strategies: Out vs. Up

Dixon and Carlson-Wee discuss the different approaches to scalability: scaling out (adding more computers) versus scaling up (adding more power to existing systems). They highlight how newer blockchain protocols are designed for scalability from the ground up, mentioning strategies like sharding and parallel processing to accommodate increased demand without significant sacrifices in performance.

Promoting On-Chain Governance

Another critical discussion point is the necessity for effective on-chain governance to allow blockchain projects to adapt and evolve over time. Dixon and Carlson-Wee explore the challenges that Bitcoin and Ethereum face with governance and the potential risks that can arise. They suggest that established frameworks for upgrades and decision-making are needed to foster long-term sustainability.

The Rise of Stablecoins and DeFi

The conversation transitions to decentralized finance (DeFi) and the significant role stablecoins play in the landscape. Dixon underscores the importance of crypto-collateralized stablecoins in mitigating volatility in financial transactions, thus enabling broader application of cryptocurrency in everyday finance. The advent of DeFi is seen as a major leap forward, paving the way for novel financial instruments and services.

The Future of Autonomous Code

Dixon and Carlson-Wee envision a future where autonomous software operates independently and can control business processes without intermediary intervention. This concept of compositionality and ownership over digital assets opens up new realms of possibility for blockchain applications, allowing for innovation in ways previously unconceived.

Emerging Opportunities and New Applications

The closing segment explores potential future applications of blockchain, including the possibility of creating marketplaces for various digital goods and services. The hosts analyze how interoperability among digital assets could drive new business models and user experiences, suggesting that the next wave of blockchain innovation will be about rethinking not just products, but entire industries.

In a followup to one of our most popular podcast episodes which originally aired in April 2017 (https://a16z.com/2017/04/03/cryptocurrencies-protocols-appcoins/), a16z Crypto Fund General Partner Chris Dixon returns to talk with Olaf Carlson-Wee of Polychain Capital in a free-wheeling conversation about the seven major trends they see happening in blockchain computing now as we shift from basic protocol design to pragmatic product launches:

Improving developer productivity
Scaling out versus scaling up
On-chain governance
Proof of Stake Networks, and especially their resilience to attacks
2017: year of of fund raising, 2019: year of launches
Autonomous and re-mixable code
Killer apps: distributed finance and beyond
