There are only two successful blockchains producing abundant real-world utility in the top 50 that have explicitly recognized and embraced this fact. Bitcoin and Bittensor. More than 780 quintillion hashes per second are currently being performed off-chain to secure and create everyone's Bitcoin. If this had to be done on-chain, Bitcoin would not exist." Link

- * * \ *💸 COSS Liquidity (M&A + IPOs)**
JJ: "Big congrats to @spyced and @ChetKapoor on exiting to @IBM. We @OSSCapital are proud investors of @DataStax for many years now. On the heels of @HashiCorp recent exit to @IBM as well (just cleared UK reg approval today), the @IBM portfolio of commercial open source continues to grow strongly. Open source is the future of software --- this strategy will pay off handsomely for @IBM going forward. Well done @ArvindKrishna!" Link
JJ: "Open source is the highest performing public investment by FAR ... and private (just a bit tricker for mainstream public to participate in the meteoric growth of private COSS startups thanks to regulators)." Link
🛠️ COSS Jobs
- 5,662 jobs and 330 companies hiring! Link
- JJ: "Really excited by our momentum at @hoppscotch_io in defining the future of API development. We're now serving many millions of users and hundreds of enterprise customers globally --- and scaling founder led sales. DM if this mission excites you. Hoppscotch.com" Link
- Bailey Pumfleet: "I don't care about your resume. At @calcom, we hire differently. - Can you ship fast? - Are you hungry to learn? - Do you challenge the status quo? Our best engineers had never built a scheduling product before. Our most successful sales person had zero enterprise experience. The thing is, when you're building something new, traditional experience can be a liability. I don't need you to tell me "how it's always been done." I want you to ask "why can't we do it better?" I'll take a passionate beginner over an "expert" stuck in their ways any day. Plus, if you're cool, you'll fit right in." Link
