If @ferkrell isn’t out training for a marathon, then he’s busy being the backbone of our entire Engineering team at Espresso Systems. Read more about Fernando below 👇
"I moved from Chile to be closer to the ecosystem—more meetups, more conferences, more time in person with the team.
This isn’t my first time living in the U.S. I did my PhD at Columbia, from 2010 to 2015. That’s actually where I met Ben—my advisor asked me to supervise him while he was visiting the program. We worked on a project about private database searches, long before either of us were thinking about blockchain. But we were already thinking about privacy.."

With AI agents moving more capital on their own, every second spent waiting on settlement is a disadvantage.
The edge will go to infrastructure that settles at machine speed.

Until recently, a slow leader could stall an Espresso block that already had the votes it needed. Not anymore.
Achieving subsecond finality meant redesigning HotShot, Espresso's consensus protocol, so each block finalizes inside its own view. Deep dive:

Getting Espresso to 1 million TPS meant rebuilding consensus, networking, block building, and data availability as one system, instead of tuning four separate ones.
Here’s a deep dive about how our engineers did it:

Banks want the verifiability of public chains, but privacy rules they control.
Today at @lfdecentralized’s privacy workshop, @ellierdavidson explains why the future of onchain finance will be many specialized chains on a high-performance base layer.

MegaETH has a soft spot for teams that refuse to accept the usual tradeoffs.
Espresso's latest benchmark pairs enormous throughput with sub-second finality. No small feat.
Something's brewing… ☕🐇

New metric just dropped: TPC. Transactions per cup. Ours is 300 million.
@ditchthebanks @EspressoSys At 1M TPS, Espresso can process about 300 million transactions while you enjoy a 5-minute coffee—all with finality still under 1 second.
Faster settlement improves tokenized products, but distribution is the near-term growth lever.
Tokenization lets institutions reach stablecoin holders who wouldn't otherwise invest in products that only exist off-chain, says @benafisch.

Our stacked list of Co-Founders includes @benediktbuenz who has probably worked on something you’ve used in the blockchain space recently. Who knows Benedikt from his early days??
"I first came to the U.S. as an exchange student in high school. It wasn’t Silicon Valley or New York—just a tiny town in rural Michigan—but I loved the culture. People were optimistic, outgoing, and driven. That stuck with me. So when grad school gave me the opportunity to return, I took it. I’ve now been here over a decade.."

8 months ago, Espresso upgraded to fully decentralized proof-of-stake. The foundation, network security, and fee structure for a state-of-the-art blockchain.
Since then, we’ve maintained a permissionless network, worked with 100 validators staking $ESP, updated HotShot to finalize blocks in under a second, and achieved enterprise-scale throughput.
We’re still building and there’s more to come.

Espresso’s Chief Product Officer never ceases to amaze. If you don’t already know @ellierdavidson, be sure to follow her for some big-brain content.
"I was a computer science major in college, and I needed one more elective to graduate. There was this blockchain class—great reviews, no clue what it was about—but I’d heard of Bitcoin, so I signed up. Dan Boneh and David Mazieres were the professors. I walked out of that class completely obsessed. I didn’t want to work on anything else. Crypto was it.."

Unlike legacy L1s built to be monolithic execution environments, Espresso was built as a base layer for other chains from day one, leaving execution entirely to the independent chains that rely on it for subsecond finality and throughput designed to scale to millions of TPS.
