a16z Podcast: Trends in Cryptocurrencies

Episode Summary

Executive Summary: This A16Z Summit discussion argues that crypto’s real significance is not speculation but the emergence of decentralized protocols that can replace centralized internet services with verifiable, user-owned networks. Juan Benet and Olaf Carlson-Wee emphasize infrastructure first—storage, compute, scaling, verification, and governance—before consumer apps arrive, while also warning that ICO hype, weak governance, and poor security standards must be disciplined for the space to mature.

Main Topics: Decentralized protocols as the next internet layer (Priority: 5/5): The speakers frame crypto as a shift from company-owned platforms to peer-to-peer protocols owned and controlled by users, with tokens enabling coordination and value capture. Filecoin, IPFS, and useful proof-of-work (Priority: 5/5): Juan Benet explains how Protocol Labs aims to turn the energy spent on consensus into useful work like decentralized storage, using IPFS and Filecoin to create a distributed cloud storage market. Infrastructure before consumer apps (Priority: 4/5): Both speakers stress that the ecosystem is still in an infrastructure-building phase; consumer-facing applications like a 'Twitter protocol' will come only after storage, verification, and scaling layers mature. Scaling and verifiable computation (Priority: 4/5): The discussion covers Ethereum’s throughput limits and the need for off-chain computation, proofs, and other scaling techniques so decentralized systems can support real applications. ICO boom, capital formation, and hype (Priority: 5/5): They describe ICOs as a powerful new crowdfunding mechanism that accelerated development, while also producing scams, noise, and the need for stronger curation and diligence. Governance and protocol upgrade mechanisms (Priority: 4/5): The conversation highlights the lack of clear governance in live crypto systems and explores on-chain governance, proof-of-stake voting, and lessons from open-source projects like Linux. Security, censorship resistance, and internet freedom (Priority: 4/5): The speakers argue decentralized systems are important for security and anti-censorship, citing examples like the Equifax/DNC breaches and Catalonia using IPFS after website censorship.

Key Arguments: Decentralized networks matter because centralized cloud providers are not truly free at scale and can become expensive, brittle, and controlling once users depend on them for critical data. Filecoin’s model is to create an algorithmic marketplace for storage so excess global capacity can be monetized by providers who otherwise could not compete with Amazon-like incumbents. Tokens and protocols can align incentives so that work currently spent on wasteful mining is redirected into socially useful computation or storage. The ecosystem is still early; infrastructure such as IPFS, Filecoin, and verification tools must exist before mainstream consumer apps can succeed. Ethereum and similar systems need scaling via off-chain computation, proof systems, and other optimizations to support practical throughput. ICOs are theoretically powerful because they let globally distributed believers fund protocols directly, but the mechanism has attracted fraud and low-quality projects. Protocol governance is unresolved; without clear upgrade processes, communities can split or stall, so on-chain governance or other formal mechanisms are needed. Decentralized protocols can preserve internet openness and censorship resistance in a future where governments or large entities restrict access or control digital life.

Data Points: Bitcoin discovery year: 2011 - Olaf Carlson-Wee says he first found Bitcoin in June 2011 and then went down the "rabbit hole". Protocol Labs founding year: 2014 - Juan Benet says he started Protocol Labs in 2014 after building IPFS and early Filecoin work. Ethereum throughput: ~10 transactions per second - Used to illustrate the scalability gap between blockchains and centralized systems like Facebook. Bitcoin power consumption comparison: More power expensive than all of Slovenia - They cite an estimate that Bitcoin mining used more electricity than Slovenia, noting it had likely increased further. ICO fundraising speed: $100 million in 30 seconds - Used to illustrate the speed and efficiency of capital coordination in ICOs. ICO scale: Billions raised in the last year - They reference the aggregate amount raised through ICOs as evidence of an inflection point in crypto funding. Consumer app timeline: Late 2018 to 2019 / about three years - They predict consumer-facing decentralized apps will emerge after current infrastructure work. Scaling horizon: Next year or two - They expect major scaling improvements and live implementations to arrive over the next one to two years.

Pivotal Quotes: "Once you start thinking about it, nothing else feels interesting anymore." — Olaf Carlson-Wee: Describing his early immersion in Bitcoin and why the idea became all-consuming. "An Airbnb for storage, where it's mediated by a token." — Juan Benet: Explaining Filecoin’s market design for decentralized storage providers and clients. "For the first time, we're seeing cryptocurrency technology being used to accelerate the development of cryptocurrency technology." — Olaf Carlson-Wee: Characterizing ICOs as a self-funding mechanism for the crypto ecosystem.

Implications: The discussion suggests crypto’s long-term value lies in new trust, storage, governance, and incentive layers for the internet. If infrastructure and governance improve, decentralized protocols could compete with major web platforms, strengthen censorship resistance, and reshape how digital services are built and owned.
