Farcaster, a blockchain-based social protocol founded by two former Coinbase employees, announced a $150 million fundraising round led by Paradigm, with additional investment from a16z crypto, Haun Ventures, and others. Farcaster allows developers to build apps on its platform, with the most popular being Warpcast, a social network similar to Twitter.

Farcaster takes a hybrid approach, storing user identities on-chain while keeping data like posts and reactions off-chain. Users pay a small fee in Ethereum to store their data, or older posts will be deleted when new ones are made. This system prioritizes security and minimizes costs by limiting on-chain actions. Storing identities on-chain helps verify users, though it’s not foolproof since one person can create multiple wallets.

Farcaster also supports topic-specific channels, allowing users to liveblog events like the NBA finals without cluttering followers' feeds. Additionally, developers can showcase their apps using the Frames feature on Warpcast. However, using Farcaster requires a digital wallet, making the platform more suited to crypto enthusiasts than the general public.

Despite the complex structure and reliance on crypto, Warpcast has about 80,000 daily active users and 350,000 signups, which is smaller compared to decentralized platforms like Bluesky and Mastodon. The $150 million raise is significant, especially in the context of a 68% drop in crypto venture funding in 2023. However, Farcaster’s backing by crypto-focused firms shows confidence in the platform’s potential.
