6/ @dankrad talks about the future of real-time proving and how latency, UX, and economic viability intersect.

Dankrad Feist

@dankrad

In the light of Succinct's announcement of real time proving, I think we should think about how we are going to use provers in the next few years.

I don't think the time to put limits on provers is now:

Relaxing the prover hardware requirements for the next few years

Real-time proving has arrived Last week, Succinct announced that they had achieved real time proving: We should see this as an amazing success, and as the time the big bet Ethereum made on ZK is...

14/ @VitalikButerin reflects on cashless societies and their discontents.

vitalik.eth

@VitalikButerin

Nordics are walking back the cashless society initiative because their centralized implementation of the concept is too fragile. Cash turns out necessary as a backup.

Ethereum needs to be resilient enough, and private enough, to be able to credibly play this kind of role.

15/ @MikeSeligEsq argues staking activities aren’t securities transactions, pushing back on regulatory assumptions.
