At Blockstream, we are first and foremost a Bitcoin development company, and are always thinking of ways to improve Bitcoin's security.

See the whole recap. ⬇️ https://blog.blockstream.com/blockstream-com-blog-us-tour-2025/

In 2017, Blockstream set out to develop a smart contract language that outperforms Bitcoin Script and EVM, offering more expressiveness with stronger safety assurances. Eight years later, we believe we have achieved this with Simplicity.

With the arrival of Simplicity on Liquid mainnet today, we now have, for the first time, a clean foundation for serious financial applications, free from the complexity and patchwork of risks that defined the last era of DeFi.

🚨 Stay vigilant 🚨 With Bitcoin near all-time highs we’re seeing more impersonations of Blockstream using fake posts, websites, and emails.

Don’t trust, verify.

If you spot suspicious content claiming to be us, submit a support ticket via help.blockstream.com

Wherever you are, Bitcoin’s in the lead.

Download the open-source, non-custodial Blockstream app and track every new all-time high in real time.

On this day in 2008, Satoshi Nakamoto emailed Adam Back about citing Hashcash in the Bitcoin whitepaper. Adam replied the next day and later co-founded Blockstream to help build Bitcoin’s future.

That future is now. Bitcoin’s here. Make it yours with the Blockstream app.
