1st Place: Infinite Drip
Infinite Drip is a CPU-friendly proof-of-work faucet that anyone (even AI agents) can use to obtain cryptocurrency, with a specific focus on testnet tokens.
Traditional faucets use burdensome anti-Sybil protections—like CAPTCHAs, mainnet balance checks, or social media logins—to rate-limit the distribution of their funds. This is because users provide no value back to the faucet, causing it to eventually run dry.
With Infinite Drip, users participate in proof-of-work to create real value, which is then exchanged for the coins they want, while market forces ensure the supply stays topped up.
Unlike traditional faucets, where an influx of users drains resources or slashes payouts, Infinite Drip scales dynamically. Assuming liquid markets, having more participants actually amortizes the cost of running the faucet, leading to greater efficiency for everyone.
Running autonomously within a TEE, Infinite Drip is entirely self-funding even with a modest number of active users. It automatically exchanges a portion of the user-created value to cover its own cloud computation costs and stay online.
Thanks to an integration with Crossroads (an IC3 research project), anyone can add new blockchains to the faucet in an entirely permissionless manner, without needing approval from a developer or swap platform.
