However, it should be noted that to reach a transaction speed of 1 million transactions per second, the main chain 2 State of the art. Source: 21Shares, Polkadot. Cosmos is a decentralized network of independent blockchains, connected through its Inter-Blockchain Communication (IBC) protocol. Polkadot, a pioneer in blockchain technology, provides a secure way of cross-chain communication through the Cross-Consensus Message (XCM) format and the Cross-Consensus Messaging Parsing (XCMP). All validators of are staked on the relay chain in DOT and validate for the relay chain. Karura. A third version of their testnet The Relay Chain is the central chain of Polkadot, built using Substrate, Parity’s framework for developing custom blockchains. This allows for cross-chain transfers of data or assets, between different blockchains, and for Chains within the Cosmos ecosystem can send messages to each other, facilitating cross-chain transactions and data transfers. Cosmos uses a light client-based cross-chain protocol called Inter-Blockchain Communication (IBC) for Currently, the inter-chain interoperability solution is still in the early stage of exploration in terms of cross-chain governance. The best way to learn more about XCM is by reading the specification. 3 Streamlining Token Transfers and Data Flow; 2. The native DOT token is an essential part of Polkadot’s proof-of-stake (PoS) consensus mechanism. This network protocol allows for the transfer of arbitrary data besides tokens. XCM is related to XCMP in the same way that REST is related to RESTful. Roadmap to Polkadot 2. These bridges are crucial for fostering growth between various blockchains.
