Check out our 2022 review!

We're incredibly grateful to have the opportunity to work on #Bitcoin & push the boundaries of what's possible in the space.

We thank our collaborators & competitors for pushing us to constantly improve.

We look forward to continuing to build & seeing what the future holds!

We’re excited to announce that we’ve raised $125 million in convertible note and secured loan financing to expand our institutional #Bitcoin mining colocation services.

“Blockstream had a strong 2022 with 3x revenue growth from 2021, & strong demand for hosting into 2023 to expand for, with a return to a bullish market, with Bitcoin up 40% in the first 3 weeks of 2023 alone.”

IMPORTANT REMINDER for Liquid developers and members: On January 25, at block 2197440, the DynaFed transition occurred successfully. As a result, peg-in addresses generated before that date belong to the previous fedpegscript. Old addresses will be honored for a limited period, until the end of the current epoch, on February 7.

Funds sent to old peg-in addresses will be lost as Elements will not accept the claim transaction. This does not affect already claimed funds, as this only applies to new peg-ins.

Please confirm that you are not caching or reusing old peg-in addresses in your code. For those not doing peg-ins, nothing has changed.

If you have any questions, please ask us here or by email: liquid-support@blockstream.com.

The future is bright for #Bitcoin and #BuildOnL2 is the platform where you can help create it.
