Shared Security in Polkadot

July 2 @ 17:30 - 19:30

“Shared Security in Polkadot”

Alistair Stewart and Bill Laboon will discuss shared security in Polkadot. It will cover the basics of how Polkadot works and what shared security is, as well as the benefits to the system provided by the shared security of Polkadot over other models. This includes the ability for even small chains to be supported by the security of the entire network and easier secure cross-chain communication. Finally, we’ll discuss some of the specific decisions made in implementing shared security in Polkadot.

When: 2nd July 2020
The door opens at 5:30 pm
Presentation starts at 6:00 pm
Where: Liquid Lounge @ CV Labs or tune in our Youtube channel
Presenters: Bill Laboon & Alistair Stewart
