The infrastructure decisions being made now will shape how institutional finance settles for decades.
Espresso co-founder @benediktbuenz on the enterprise conversations Espresso is having with major financial institutions, on @zeroknowledgefm.
English
@arbitrum What about an L1 built from scratch to serve as a base layer for other chains, while not competing with them at the execution layer?
English
Institutions don't need an L1.
They want control over revenue, customization, security, liquidity and distribution.
Here's why a dedicated blockchain with the Arbitrum Platform, in the form of an L2, is the best option.
0:00 Costs
1:15 Revenue
2:04 Customization
2:59 Security & finality
5:16 Operational complexity
5:57 Liquidity & distribution
6:37 Launch & migrate
English
On a shared blockchain, none of these are yours.
On a dedicated chain built on Espresso, all of them are:
· Your fee model
· Your compliance layer
· Your upgrade schedule
· Your sequencing revenue
English
A conversation worth listening to.
Espresso co-founder and NYU computer science professor @benediktbuenz on zero-knowledge proofs, post-quantum Bitcoin, and the cryptographic tools that could reshape the protocol.

BITCOIN RAILS #69: ZERO-KNOWLEDGE PROOFS FOR POST-QUANTUM BITCOIN | with Benedikt Bünz 🔗 YOUTUBE: youtu.be/v8-4HWz5jV0 🌿 SPOTIFY: open.spotify.com/episode/4vy3UJ… While many Bitcoiners remain hopeful the network will embrace zero-knowledge proofs for protocol-level use cases, practical adoption has remained limited outside of BitVM and a handful of experimental proposals. Most of the world’s ZKP research has circled around Ethereum and other ecosystems, where significant resources have been dedicated to advancing these systems, particularly for scaling and privacy applications. One of the most notable contributors to this research is @benediktbuenz — professor of cryptography at NYU and collaborator of @danboneh, who together inarguably form one of the strongest blockchain-applied cryptography teams in the world. The pair recently announced they’ll be leading the new post-quantum cryptography unit @lclhostresearch — the first dedicated PQ research effort within a major Bitcoin development organization. With Benedikt leading the charge on the use of zero-knowledge proofs for post-quantum mitigation, the question emerges: will the post-quantum transition be the catalyst to finally bring zero-knowledge proofs to Bitcoin's core protocol? In more detail, Benedikt and I discuss: - Why ZKPs haven’t been widely adopted by the Bitcoin technical community — and why the threat of quantum computers may change that posture going forward - How ZKPs could be used for signature batching to address larger post-quantum signatures in Bitcoin’s post-quantum era - Why Bitcoiners will likely prioritize hash-based signatures as an initial post-quantum scheme — rather than more efficient but less proven alternatives (e.g., lattice-based) - How ZKPs have evolved over the last decade and may finally be ready for Bitcoin’s strict requirements around trust assumptions - Why Benedikt and Dan are teaming up with @lclhostresearch to create the first post-quantum cryptography unit within a major Bitcoin development organization + what they hope to accomplish This episode of Bitcoin Rails is brought to you by: LayerTwo Labs @LayerTwoLabs — developing research, software, and technologies for scaling Bitcoin via the integration of Drivechains (BIP 300/301) Hashi on @SuiNetwork — a primitive for executing Bitcoin DeFi transactions, without having to trust a federated bridge or other centralized entity BitBox @BitBoxSwiss — an open-source Bitcoin-only hardware wallet, with smooth UX and no compromises on security.

Not all institutional blockchain adoption is the same.
Espresso co-founder @jillgun breaks down two paths driving institutional adoption right now, and what separates them, live at @money2020.
English
Builders face a real tradeoff: join a monolithic chain and inherit its constraints, or build independently and lose interoperability.
Espresso changes that. Any chain can plug in for fast finality and real-time settlement without giving up sovereignty or architectural control.

Congrats to our co-founder & CEO @benafisch (also a Yale professor) on his National Science Foundation CAREER award. It'll fund years of research into private, verifiable computation, the kind of cryptographic primitives tomorrow's digital economy will be built on.

The caffeine is coming ☕
@EspressoSys pre-confirmations are coming to Celo later this year!
@KateGielty & @jillgun explain why low latency & fast finality are crucial for global stablecoin payments
English
Espresso Systems got its start building a privacy product for compliant stablecoin payments. Then came the pivot that changed everything.
CEO & Co-Founder @benafisch on how Espresso got to where it is today.
English
H1 delivered. Jovian shipped, zk proof generation set to get 75% faster, and the op-reth migration is underway.
H2: the caffeine arrives. @EspressoSys brings fast confirmations, op-reth hits Mainnet, and Karst is on deck.
H2 roadmap below 👇

Most active L2 on Ethereum, and soon the fastest to finality too. Congrats @celo.
marek.gwei@marek_
Celo has taken the lead again as the most used Ethereum L2 by DAUs. Let's go!

Listen back to the full conversation from last week.
We covered Q-Day timelines, why Ethereum is betting on hash-based signatures, what makes Flock stand out, and where post-quantum cryptography is heading.

What is a SNARK, and why do hash-based SNARKs matter for post-quantum security?
@kleptographic breaks it down in simple terms, from our X Space on Flock with @SuccinctLabs last week.
English
Like wire transfers crossing many banks, crosschain transactions with slow finality rely on intermediaries that add time, cost, and points of failure before settling.
Espresso removes the middlemen, finalizing a chain's new state in real time so others can act on it immediately.
English
@nyakiomaina11 @SuccinctLabs Thanks for putting this together! Great breakdown 🤎

Missed yesterday's spaces on Flock?
We've got you covered with notes on:
→ Q-day timelines
→ Flock: The fastest SNARK prover for standard hashes
→ What it means for Ethereum's post-quantum roadmap
ft. @benediktbuenz, @ronrothblum, @kleptographic and @drakefjustin.

Espresso was built as infrastructure, not a venue.
It doesn't host apps or run custom logic. It gives chains fast finality and real-time settlement, then gets out of the way. What those chains host, who uses them, and how they're architected stays with the teams building them.
