Cosmos released a new white paper introducing a cross-chain security mechanism that allows chains to rent security from the Cosmos Hub, similar to Polkadot’s shared security model. The new white paper also proposes the introduction of liquid staking across chains, with Cosmos Hub’s new liquid staking model generating revenue from various sources, including inter-chain transaction fees and inter-chain security fees. In addition, Cosmos Hub introduces a governance stack to provide a common system for decentralized autonomous organizations (DAOs). The continuous innovation and development of the Cosmos ecosystem enables it to achieve better results in cross-chain support, security, interoperability and user experience.
