Bitcoin at Block
Building a more open, accessible, and equitable global system
For over a decade, Block has championed bitcoin. We believe it’s the best technology we have for a native currency of the internet, one that breaks down barriers and enables economic empowerment for everyone. With bitcoin, we can work toward financial access without gatekeepers, borders, or discrimination.
From pioneering bitcoin access through Cash App in 2018 to launching Lightning payments, building self-custody solutions with Bitkey, and developing open-source mining hardware with Proto, we’ve consistently shipped technology to advance bitcoin and expand access for our customers. Now, as we roll out native bitcoin payments across millions of Square merchants, we’re building a future where bitcoin becomes everyday money that truly empowers economic freedom for all.

Square enables millions of merchants to accept bitcoin payments directly through their Square hardware using the Lightning Network for near-instant, low-cost transactions.

Block has been a leader in corporate bitcoin adoption since 2020, and now anyone can independently verify the bitcoin we custody — corporate treasury and customer holdings alike. Don’t trust. Verify.
Bitcoin Discovery Grants
Our grant program is a $5M commitment to nonprofits increasing bitcoin education and adoption in historically under-resourced communities around the world — because everyone deserves a chance to participate in the future of money.
Bitcoin Policy
Block is building toward a world where bitcoin is more than just a store of value. To realize this vision, we encourage Congress to modernize regulatory frameworks and unlock a tax barrier for small-dollar bitcoin transactions to be a practical medium of exchange in the US.
Bitcoin and Clean Energy
We believe bitcoin mining can help accelerate a transition to sustainable energy all over the world. That’s why we invest in projects like Gridless, which powers bitcoin mining with renewable energy in rural Africa.
CCI (Crypto Council for Innovation)
As a founding member of CCI, we strongly advocate for thoughtful, technology-neutral bitcoin policy through one of the leading global crypto trade associations. We work with them to build a positive narrative for bitcoin policy while engaging with regulators and policymakers at the state, federal, and global level.
Texas Blockchain Council
As a board member of the Texas Blockchain Council, we support pragmatic, pro-innovation bitcoin policy at the state level, with a focus on Texas. We work with the Council to highlight how mining can strengthen grid resilience, boost U.S. leadership in mining technology, drive investment in energy, and support rural economic development.
