Polkadot vs Cosmos Cage match (DOT vs ATOM)

Kris: Welcome crypto nation to 
the battle of the blockchains.   I’m Kris – here with Davey Zelaya the 
Slaya as we pit Polkadot against Cosmos! Davey: There’s been a lot of tension building 
between these two. As we know, there are hundreds   and hundreds of blockchains in existence, 
but who will be the one to unite them all? Polkadot and Cosmos are both 
vying for that top position to be   THE ONE to connect all blockchains together.

Kris: Relay chain or hubs, bridges or pegs,   Substrate or Cosmos. Let’s not get too 
technical. We’re here to find out which   one will win the fight. While they certainly 
do it differently, both projects share one aim:   to build interoperability between blockchains.

Davey: so let’s get down to what matters most:   Security. Polkadot operates under a shared 
security model so that new and smaller chains can   basically bootstrap and outsource their 
security to Polkadot instead of trying   to secure their network on their own.

Kris: The downside to this is that if   the Polkadot GRANDPA consensus goes down, so does 
everyone in the relay chain.

And don’t you think   it might give the Polkadot validators a little 
too much power? How much do you think that shared   premium security will cost in terms of tradeoffs?

Davey: This is where Cosmos could have an edge.   Cosmos is big on sovereignty and each chain 
securing its own set of validators. Chains can   request for a hub to pool security, 
but overall, the Cosmos framework   gives individual chains more control.

Kris: But it’s each to their own here.   Some networks just want to get up and running 
without expending too much on security. Plus,   all Polkadot chains will trust in their shared 
and uniform security, ultimately enhancing   interoperability with each other.

Davey: That’s a great point, Kris.   It does sound more efficient but, can.

It. 
scale? How many blockchains can Polkadot support?   At last estimate it’s around 100 parachains.
  100 sounds like a lot, but Cosmos 
essentially has no limits.
  And you also have to stake a sizeable amount 
of the DOT token to launch a chain on Polkadot   while anyone can build on the Cosmos 
network without such restrictions. Kris: Which brings us to governance. 
Polkadot on-chain governance is   determined by DOT holders who vote for 
changes based on their staked amounts. Now, the Cosmos hub works in a similar way, with 
ATOM holders allowed to vote on proposals. But,   unlike Polkadot, each chain in the Cosmos 
network actually follows its own set of rules. Davey: Cosmos could actually be better for 
multiple blockchains wanting to maintain   greater sovereignty, while still being 
connected with other blockchains. Kris: But we all know that it 
comes down to the network effect.   Who has the biggest ecosystem and builders? Davey: The Cosmos network is already home to 
many big names including Binance, BAND protocol,   Bluzelle…and those are just the ‘B’s in the list!

Kris: Polkadot’s ecosystem is just as formidable.   How can you look past its cousin Kusuma, 
Polkadot’s canary network and testing   ground enjoying great success.

Not to 
mention other promising projects such as   PolkaStarter and Moonbeam. In total over 300 
projects are listed on PolkaProject which is   nearly double that of Cosmos to date.

Davey: That’s certainly hard to beat.
  Who’s going to be the reigning 
ruler of blockchains? Or is the   crypto universe big enough for two? One 
thing is for sure…once either succeeds,   it’s the beginning of a new era for blockchains. Kris: You decide who wins in the comments.
