As new networks are tapping into Polkadot, its co-founder sees a high-stakes battleground forming over privacy and security."You want to create a system which is upgradable which can adapt to new technologies if you want to be able to stay one step ahead of the curve," says Rob Habermeier, who joins The Scoop host Frank Chaparro for a discussion on how exactly DeFi fits into Polkadot, where he sees privacy and security headed, and the hurdles that Polkadot's so-called 'parachains' face in 2022.Polkadot is still in “very early days”, said Habermeier, in terms of the interoperability of the network’s recently launched parachain functions.“A lot of this interoperability stuff that's been talked about for a very long time is just coming to fruition now. We're seeing the first parachains, we're seeing the first bridges between ecosystems," he says.Polkadot's parachains operate by allowing multiple blockchains to branch off their network. Polkadot deployed its first six parachain partnerships via the Kusama network on July 20. “And those are focusing on, for example, DeFi, on smart contracts, on layer 2 scaling, and on identity secure compute using some secure hardware," Habermeier continues.Habermeier also outlined how Polkadot’s Substrate platform works, on which Compound Labs recently launched a product called Gateway. Substrate works by reordering transactions in a block to suit the needs of DeFi institutions.“You're not going to have your profits constantly cut into by some aggressive miner who's reordering your transactions or sandwiching them,” Habermeier explained. “What that's going to do is essentially make it more difficult to exploit users who are using DeFi systems.”During this episode Habermeier and Chaparro also discuss:  Why Habermeier dropped out of college to build Polkadot Where security and privacy is headed with blockchain The challenges of finding and procuring talent in the digital asset industry Episode 46 of Season 3 of The Scoop was recorded remotely with The Block’s Frank Chaparro and Rob Habermeier, Co-Founder at Polkadot.Listen below, and subscribe to The Scoop on Apple, Spotify, Google Podcasts, Stitcher or wherever you listen to podcasts.
