What problem does this service solve?

Polkadot aims to improve interoperability and overall performance for DApps running across multiple networks.PCHAIN's multichain ecosystem will allow DApps to operate across blockchains and will enable larger scale applications.Cosmos is building a decentralized network of independent parallel blockchains. Their goal is to provide the infrastructure for anyone to be able to make their own blockchain that will be able to operate with others, and will allow transfers of value between them.

Company Description

The Polkadot blockchain is a multi-chain blockchain that is designed to bundle multiple chains together so that they can be executed in parallel. The goal is for every block on the Polkadot blockchain to contain multiple blocks from other chains. This will enable the network to contain the transaction information from multiple chains and dramatically increase the overall interoperability between different blockchain networks. Polkadot was created by the Web3 Foundation, which is led by Gavin Wood, one of the founders of Ethereum. Polkadot is their flagship project, and aims to solve the issues in the blockchain ecosystem related to disjointed governance and interoperability.

PCHAIN is developing a multichain ecosystem that will support the Ethereum Virtual Machine (EVM).PCHAIN's architecture will consist of one main chain and multiple child chains. They hope to improve transaction times with a Proof-of_Stake consensus mechanism that will be combined with sharding.. The PCHAIN network is currently powered by the Ethereum-based PAI token.

Cosmos is a cross-chain protocol that is working to establish a standardized way for blockchains to inter-operate. It has been called the internet of blocchains. Cosmos is building a standardized protocol for multiple blockchains to operate freely together, and allow transfers of value between them. Cosmos is made up of a network of blocckhains called zones. Each of these zones will be powered by a the Tendermint consensus protocol. Cosmos will act as a hub, that ties the zones together and manages their coordination. The Cosomos token called ATOM was released in an ICO that raised $53 million, but it will not be traded until the platform is launched.
