You are all wrong about rollups and it is driving me insane
- Time
- Thu, Apr 23 · 11:45 AM – 12:00 PM
- Location
- Main Stage
- Type
- talk
- Duration
- 15m
Rollups are a flavor of blockchain that rely on a parent blockchain for security and data availability. They do this so they do not have to bootstrap their own validator set. They do not need a sequencer, and they do not need a bridge. They can operate purely through bitcoin L1 transactions, or they can maintain an offchain mempool for better throughput. To provide different types of execution layers for bitcoin the asset, they can have a bridge (which can be a federation, a single custodian, or some version of BitVM). Bitcoiners were introduced to rollups through progress made in BitVM; specifically from teams in the BitVM alliance. But, these teams were building rollups before BitVM was discovered and announced. And, rollups have existed on bitcoin for over a decade! In this Lightning talk, Janusz will explain why everyone is wrong about rollups, why the rollup teams are tricking you into believing that the bridge defines the rollup, and why this semantics debate is just a rehashing of arguments from the past. Janusz will provide three examples of rollups, one with a bridge, one without, and one without a bridge & a sequencer. He will share how all three of these systems ultimately work the same from the lens of the rollup full nodes; the real users.
NostrMail - Learning from three decades of PGP
- Time
- Thu, Apr 23 · 12:00 PM – 12:15 PM
- Location
- Main Stage
- Type
- talk
- Duration
- 15m
NostrMail is a cross-platform, end-to-end encrypted email client that bridges Nostr and traditional email protocols. It avoids the pitfalls of PGP by using Nostr for key discovery, it works with existing email providers like Gmail and uses wordlist encoding (e.g., BIP39) so ciphertext and signatures remain valid under forwarding. NostrMail is open source, cross-platform, and available now on the Zapstore.
ARK in its essence

Matthew Vuk, researcher at Second, takes us on a journey to understand the essence of the Ark protocol, through the lens of Jan Sholten’s homeopathy.
BitVM3 and Binohash Don’t Improve Bridge Security. Some Soft Forks Do.
- Time
- Thu, Apr 23 · 1:00 PM – 1:30 PM
- Location
- Main Stage
- Type
- talk
- Duration
- 30m
BitVM3 and Binohash are exciting developments, but their impact on Bitcoin bridge security is often misunderstood. BitVM3 mainly improves collateral efficiency, making bridge constructions more capital efficient, while Binohash enables new forms of transaction introspection in Bitcoin Script with important limitations. In this talk, I explain why these advances do not fundamentally strengthen bridge security and explore which proposed Bitcoin soft forks actually move the needle.
Mempool policy is bitcoin's administrative state
- Time
- Thu, Apr 23 · 1:30 PM – 2:00 PM
- Location
- Main Stage
- Type
- talk
- Duration
- 30m
This talk will compare how mempool policy is like the administrative state. When a self-governing people loses the ability for rigorous public debate and political compromise, the natural incentive is to outsource governing responsibility to processes outside of the regular political sphere. Once outsourced, normal checks and balances can be circumvented with changes expedited by experts. Here, the incentives are such that increasing complexity and knowing how to work the system above all is rewarded. Ossification doesn't freeze decisions in place. It shifts the realm of decision making elsewhere. [This was just thrown together for submission. Not sure how much I'll end up reworking the description once I've had time to think about it more]
The Coming Era of Nation State Hash Wars and Implications for the Bitcoin Network

A discussion of the cultural weight that is preventing bitcoin from making changes needed to survive for centuries to come, and an optimistic look at how to break free of that weight.
Bitcoin Without Controversy
- Time

It seems that changes proposed to bitcoin are never without controversy. For this panel, we pull together veterans of the space who have dealt with their own amount of controversy over the years.
Proofless Consensus and Client-side Validation
- Time
- Fri, Apr 24 · 10:30 AM – 11:00 AM
- Location
- Main Stage
- Type
- talk
- Duration
- 30m
Proofless consensus is a family of protocols that move transaction validation client-side, and minimises the responsibility of consensus to double-spend detection. This enables high-throughput private transactions with lightweight consensus. This talk explores preliminary interfaces, the proof-carrying data graph, and open questions such as Sybil resistance.
