Farcaster has launched a new protocol called Snapchain, designed to support social media applications with efficient processing for micro-interactions. Snapchain can handle over 10,000 transactions per second and acts as a data storage layer for Farcaster. The launch coincides with Farcaster's "Airdrop Offers" program, rewarding active platform use. Farcaster, inspired by Twitter, is expanding its ecosystem to include crypto payments and mini apps. The platform has raised $150 million in funding and is valued at over $1 billion, with significant growth in user sign-ups and network activity since going permissionless.
