Cross-chain projects like Polkadot and Cosmos aim to solve blockchain interoperability, a crucial challenge for the broader adoption of decentralized technologies. Comparing their investment potential requires analyzing their technologies and ecosystem development.

Polkadot:

Technology:
Relay Chain: Polkadot’s core is the Relay Chain, which coordinates the operation of multiple parallel blockchains (parachains).
Parachains: Projects can build their own parachains, connecting to the Relay Chain for security and interoperability.
Nominated Proof-of-Stake (NPoS): Polkadot uses NPoS for consensus, where validators are nominated by token holders.
Interoperability: Polkadot aims to enable communication and value transfer between different blockchains, including external networks via bridges.
