Bitcoin at Block
In 2010, software developer Gavin Andresen, one of the key figures in Bitcoin’s early evolution, launched the original Bitcoin Faucet and handed out 5 $BTC to anyone who solved a CAPTCHA.
At Bitcoin’s all-time high, a single claim would have been worth about ~$600,000, while the more than 19,000 $BTC the faucet eventually distributed would have been worth roughly $2.39 billion.
Now, one of Bitcoin’s most legendary stories is being brought back to life ⚡
The return takes shape through Bitcoin at Block, Block’s bitcoin initiative, with Jack Dorsey leading the company as Block Head, Chairman, and cofounder.
The faucet is not returning as a simple throwback. It now points toward a broader bitcoin stack built around how people buy bitcoin, spend it, secure it, mine it, and build around it.
That broader vision takes shape across five key parts of the ecosystem:
• Cash App → Buy, sell, send, and receive bitcoin with Lightning support and Auto Invest
• Bitcoin on Square → Settle bitcoin payments with Lightning support and flexible payouts
• Bitkey → Store, secure, and manage bitcoin with self-custody, and multi-sig protection
• Proto → Build, run, and scale bitcoin mining with hardware, software, and infrastructure
• Spiral → Fund, build, and support bitcoin development with open-source tools and grants
Seen together, they make clear that the original Bitcoin faucet now belongs to something much larger. What made the original faucet unforgettable was how simply it placed bitcoin into new hands. What makes this revival interesting is everything that now surrounds it.
