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.

For the uninitiated, Polkadot achieves this using its Parachain network, dividing its blockchain networks into many sub-pieces so that verifying transactions can become more efficient. This ensures that a designated community or validator verifies data on every shard, instead of an entire network going through and getting updated with every new information.

Today, Joe Petrowski, a Polkadot and Parity Technologies engineer sat down with crypto edutainment platform Cryptonites to discuss the network, its technological advances, the burgeoning DeFi market, and other nuances with host Alex Fazel, leading to an insightful conversation that covered various aspects for Polkadot newbies.

Here’s everything they said.

How cross-chain bridges have poor trust models

Petrowski, who first wrote trading bots to profit off the alluring crypto markets before joining Parity in 2018, said the issue of trust models in cross-chain bridges and the absence of solid cross-chain blockchain mechanisms were among the first issues he worked on.

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. 

“One of the key things with Polkadot is that we kind of link all of these things together, so that they can share some common context and actually have this security where everybody has an equal level of security.” Kingdom Kusama

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...
