Inside a Polkadot developer’s mind on Kusama, Parachains, and decentralized governance

Polkadot emerged as one of the biggest “Ethereum killers” this year, with its high throughput, low-fee network, and the demand for such features booming as the DeFi sector surged in 2020. It is maintained by five individual teams.

He pointed out popular bridges largely depend on trust-based models where blockchains interact with each other, but that network security forms a huge concern in such systems. Polkadot cuts this out, he said.

Petrowski also shared that the decentralized governance features, which incentivize participation on the network, made Polkadot a more-balanced project. 

“Anybody who has a stake in the system can participate either as a c...
