“Bitcoin Second Layers’s Security and Privacy — Lessons from the War Trenches”
Antoine Riard;
Talk
Going from 2015 with the initial proposal of the Lightning Network to today.
The technical security and privacy shortcomings of a different categories of bitcoin’s second-layers (payment channels, coinjoin, coinswaps, statechains, time-sensitive wallets, vaults, etc).
“One Slice Left. Who Gets It? A talk about quantum computing.”
Nicolas Vescovo;
Talk
One Slice Left. Who Gets It? A talk about quantum computing, Bitcoin, and why waiting is not a strategy. In this session, RootstockLabs’ in-house mathematician and quantum researcher Nicolás Vescovo breaks down why the quantum threat isn’t a slow fade but a sudden grab: once scalable quantum computers arrive, algorithms like Shor’s could expose private keys from public keys, undermining Bitcoin and its layers like Rootstock overnight. The focus is on what quantum-proofing Bitcoin actually require, where current protections fall short, what migration paths exist, and the trade-offs and open questions the Bitcoin community still needs to face.
“To Filter or Not To, Decision Under Uncertainty and the Fracturing of Relations”
Karo Zagorus;
Talk
Societal pressure is building on decision making in Bitcoin and this is raising social capital costs as solutions require more abstraction and deliberation of what directions bitcoin can go into. This can feature relations and make long term delays in decision making for contributors, let's take a look at these factors and how we can get ahead of the curve be learning to compromise or not. Changing bitcoin can be dangerous but how much can we actually veer off the path until we end up with a shitcoin again and becoming a societal outcast in the Bitcoin space?
“You’re using Bitcoin — Do you know the rules you’re playing by?”
ALEKSANDR SARYGIN;
Talk
Do we ever stop and think about Bitcoin not just as code — but as a system with its own rules?
Imagine this:
Miners include your transaction in a block — are they just processing it, or actually making a decision that matters legally?
Your transaction appears on-chain — but when is it truly final in a system with no central authority?
And if everything is public… are you really anonymous — and do privacy laws still apply?
Sounds simple — until it isn’t.
These aren’t “legal questions.”
They’re real-life situations that most people run into without even realizing it.
The idea behind this talk is straightforward:
Bitcoin isn’t just technology. It’s a system with its own rules — and whether you know them or not, you’re already playing by them.
