Gummiworm: - Motivated by explaining L1 and Hydra trade-offs - L1 is very decentralized, but slow - Hydra is very fast, and fully secure, but requires "small world" - Key idea: split responsibilities of execution and custody - Short term custody vs. long term custody - People are fine with more centralized custody in the short term - For example in exchange of fast user experience - Multi-frequency Hydra - at least two levels of confirmation - Validation should be pluggable - Big multi-sig at first - stake-based or zk solutions thinkable too - Being able to check the health of the system - also to create back pressure - Good behavior incentivized through slashing = optimistic protocol - This makes a lot of sense on Cardano as SPOs could collateralize their pledge DeltaDefi: - Developing ongoing over last couple months - Identified critical issues - Working on Hydra in a way that making sure the software works before care about decentralization (aka Want to ensure no value locked if everyone is honest - Would move towards more decentralized approach after proving the product is needed by community - Brought up critical issue: https://github.com/cardano-scaling/hydra/issues/1773 - We should make sure its linked up with our latest idea how to solve it: https://github.com/cardano-scaling/hydra/issues/1858 - Sebastian pointed out that having non-finalizable head states is REALLY unsafe - Maybe partial fanouts could help? https://github.com/cardano-scaling/hydra/issues/1468 - Hinson: We think incremental decommit can serve same purpose? - Other two issues they noticed and will be closely monitoring: - https://github.com/cardano-scaling/hydra/issues/1871 - https://github.com/cardano-scaling/hydra/issues/1757
