    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.

    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.

    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.

    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.

    Financial institutions are not all going to agree to run on one chain. The future is multi-chain, and Espresso is built to be a fundamental building block underneath it. @benediktbuenz, Chief Scientist at Espresso, on why custom chains win and where Espresso fits in.

    Money moves slower than it should. Almost every inefficiency in global finance, from remittances to stock settlement, comes down to speed. Fast finality is the fix. @jillgun in conversation with @KateEldaly on the @Celo L2 year one livestream.
